This is how you can use NSXMLParser :

In your .h file declare :

NSMutableData       *webPortFolio;
NSMutableString     *soapResultsPortFolio;
NSURLConnection     *conn;

//---xml parsing---

NSXMLParser         *xmlParserPortFolio;
BOOL                elementFoundPortFolio;
NSMutableURLRequest *req;

NSString            *theXMLPortFolio;
NSString            *strSoapMsg;
UIAlertView         *alertView;











n your .m file use the following code:

-(void)callURL
{

     //Your logic to call URL.

     conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
     if (conn)
     {
         webPortFolio = [[NSMutableData data] retain];
     }
}
And to handle the response you can use following functions :

-(void)connection:(NSURLConnection *)connection

didReceiveResponse:(NSURLResponse *)response
{
    [webPortFolio setLength:0];    
}

-(void)connection:(NSURLConnection *)connection

didReceiveData:(NSData *)data
{
    [webPortFolio appendData:data];
}

-(void) connection:(NSURLConnection *) connection didFailWithError:(NSError *) error
{

    NSLog(@"error...................%@",[error description]);
    [webPortFolio release];
    [connection release];
}

-(void) connectionDidFinishLoading:(NSURLConnection *) connection
{

    //Check the request and returns the response.

    NSLog(@"DONE. Received Bytes: %d", [webPortFolio length]);

    theXMLPortFolio = [[NSString alloc]
                      initWithBytes: [webPortFolio mutableBytes]
                      length:[webPortFolio length]
                      encoding:NSUTF8StringEncoding];

    //---shows the XML---

    NSLog(@"shows the XML %@",theXMLPortFolio);
    [theXMLPortFolio release];   

    if(xmlParserPortFolio)
    {
        [xmlParserPortFolio release];
    }
    xmlParserPortFolio = [[NSXMLParser alloc] initWithData: webPortFolio];
    [xmlParserPortFolio setDelegate: self];
    [xmlParserPortFolio setShouldResolveExternalEntities:YES];
    [xmlParserPortFolio parse];
    [webPortFolio release];
    [connection release];
}

//---when the start of an element is found---
-(void)  parser:(NSXMLParser *) parser

   namespaceURI:(NSString *) namespaceURI

How to Pass Data One ViewController to Another View Ios/Iphone

=> Here Taken One Example ViewControllerA and ViewControllerB

=>For Here Used pass a BOOL value from ViewControllerA to ViewControllerB:-.

    In ViewControllerB.h declared one property for the BOOL variable:

    @property(nonatomic) BOOL *isSomethingEnabled;

    In ViewControllerA you need to Say ViewControllerB so use It:-

    #import "ViewControllerB.h"

=>  Then where you want to load the view eg. didSelectRowAtIndex or some IBAction
    you need to set the property in ViewControllerB before you push it onto nav stack.

    ViewControllerB *viewControllerB = [[ViewControllerB alloc] initWithNib:@"ViewControllerB" bundle:nil];
    viewControllerB.isSomethingEnabled = YES;
    [self pushViewController:viewControllerB animated:YES];

    This will set isSomethingEnabled in ViewControllerB to BOOL value YES.

==> Here Passing Data Forward Using The Segue's:-

==> If you are using Storyboards you are most likely using segues and
    will need this procedure to pass data forward. This is similar to the above but instead of passing
    the data before you push the view controller, you use a method called:-

=> Here Used One Of the Method Whitch is:-

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

==> Here Pass a BOOL from ViewControllerA to ViewControllerB:-

    In ViewControllerB.h create a property for the BOOL

    @property(nonatomic) BOOL *isSomethingEnabled;

    in ViewControllerA you need to tell it about ViewControllerB so use an

    #import "ViewControllerB.h"

=> Create a the segue from ViewControllerA to ViewControllerB on the storyboard and give it an identifier,
   in this example we'll call it "showDetailSegue"

=> Next we need to add the method to ViewControllerA that is called when any segue is performed,
   because of this we need to detect which segue was called and then do something.
   In our example we will check for "showDetailSegue"
   and if thats performed we will pass our BOOL value to ViewControllerB:-

    -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
        if([segue.identifier isEqualToString:@"showDetailSegue"]){
            ViewControllerB *controller = (ViewControllerB *)segue.destinationViewController;
            controller.isSomethingEnabled = YES;
        }
    }

=>If you have your views embedded in a navigation controller you need to change the
   method above slightly to the following

    -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
        if([segue.identifier isEqualToString:@"showDetailSegue"]){
            UINavigationController *navController = (UINavigationController *)segue.destinationViewController;
            ViewControllerB *controller = (ViewControllerB *)navController.topViewController;
            controller.isSomethingEnabled = YES;
        }
    }

=> This will set isSomethingEnabled in ViewControllerB to BOOL value YES.

==> Passing Data Back


    In ViewControllerB.h, below the #import, but above @interface you specify the protocol.

    @class ViewControllerB;

    @protocol ViewControllerBDelegate <NSObject>
 - (void)addItemViewController:(ViewControllerB *)controller didFinishEnteringItem:(NSString *)item;
    @end

=> Next still in the ViewControllerB.h you need to setup a delegate property and
   synthesize in ViewControllerB.m

    @property (nonatomic, weak) id <ViewControllerBDelegate> delegate;

=> In ViewControllerB we call a message on the delegate when we pop the view controller.

    NSString *itemToPassBack = @"Pass this value back to ViewControllerA";
    [self.delegate addItemViewController:self didFinishEnteringItem:itemToPassBack];

=> That's it for ViewControllerB. Now in ViewControllerA.h, tell ViewControllerA to
   import ViewControllerB and conform to its protocol.

    #import "ViewControllerB.h"

    @interface ViewControllerA : UIViewController <ViewControllerBDelegate>
=>    In ViewControllerA.m implement the following method from our protocol

    - (void)addItemViewController:(ViewControllerB *)controller didFinishEnteringItem:(NSString *)item
    {
        NSLog(@"This was returned from ViewControllerB %@",item);
    }

=>  We need to tell ViewControllerB that ViewControllerA is its delegate before
    we push ViewControllerB on to nav stack:-

    ViewControllerB *viewControllerB = [[ViewControllerB alloc] initWithNib:@"ViewControllerB" bundle:nil];
    viewControllerB.delegate = self
    [[self navigationController] pushViewController:viewControllerB animated:YES];

How to use Protocol In Ios/iphone

==> Here One Protocol Declared :
@protocol MyProtocol <NSObject>

=> Declared One Of the Method :-

  - (void)aRequiredMethod;

=> Here Required Method:
 @required
- (void)anotherRequiredMethod;

@optional
- (void)anOptionalMethod;

@end

@interface MyClass <MyProtocol>

@end

@property (nonatomic, weak) id<MyProtocol> delegate;

[self.delegate aRequiredMethod];

[self.delegate conformsToProtocol:@protocol(MyProtocol)]

[self.delegate respondsToSelector:@selector(anOptionalMethod)]

Use Category With Custom Method In Ios/Iphone

=> Here Seeing One Of the Imporetd Categortt Concept:=

#import <objc/runtime.h>

static void *MyClassResultKey;
@implementation MyClass

=> Here taken One method Of which Using Category In Ios:

 - (NSString *)test {

  NSString *result = objc_getAssociatedObject(self, &MyClassResultKey);
  if (result == nil)

{
    // do a lot of stuff
    result = ...;
    objc_setAssociatedObject(self, &MyClassResultKey,

                  result, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
  }
  return result;
}
=> finaly Object set Associate object Using Category:-

 @end

How to Use Completion Block In Ios/iphone

=> Here Work with returnType (.h above @interface declaration)

=> typedef void (^CompleteDiceRolling)(NSInteger diceValue);

    Declared With One Of the a @property for the block (.h)

    @property (copy, nonatomic) CompleteDiceRolling completeDiceRolling;

    Declared here One Of a Method with finishBlock (.h)

    - (void)getDiceValueAfterSpin:(void (^)(NSInteger diceValue))

     finishBlock;

=>  Use Periviose Method in .m file and commit finishBlock to @property
    declared before:-

    - (void)getDiceValueAfterSpin:(void (^)(NSInteger diceValue))

     finishBlock{
        self.completeDiceRolling = finishBlock;
    }

=>  Here Use completionBlock Pass Predefined variableType to it
    (Don't forget to check whether the completionBlock exists):-

    if( self.completeDiceRolling ){
        self.completeDiceRolling(self.dieValue);
    }

    => Finaly Use it With Work Completion Block.

How To Create Databse .DB Sqlite File In Ios/iphone

=> Hare Call the Method Of Whitch Declared Belove Side:

-(BOOL)application:(UIApplication *)application

 didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.

    [self createDb];

    return YES;
}
==> Create One Databse File And Create Db And Usingf Some Method:

 -(void)createDb
{
    NSArray *dir=NSSearchPathForDirectoriesInDomains

   (NSDocumentDirectory, NSUserDomainMask, YES);

    NSString *dbPath=[NSString

    stringWithFormat:@"%@/userDb.sqlite",[dir lastObject]];

    sqlite3 *db;

    NSFileManager *fm=[NSFileManager new];

    if([fm fileExistsAtPath:dbPath isDirectory:nil])
    {
        NSLog(@"Database already exists..");
        return;
    }

How To Use Animated ANd Hide Show UIView In Ios/Iphone

==> First Take Pne IBOutlet Of UIView And Then Use Animated:
==> How to Hide ANd Show Some Kind Of UIView In Ios:
import <UIKit/UIKit.h>

@interface ViewController: UIViewController
@property (strong, nonatomic) IBOutlet UIView *cautionView;


- (IBAction)btnToggleClick:(id)sender;
@property (strong, nonatomic) IBOutlet UIButton *btnToggle;
@end
.m file:

#import "ViewController.h"

@interface ViewController()
@end

@implementation ViewController

bool isShown = false;
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
=> USe tHIS Action To toggle Click On Button:-
 - (IBAction)btnToggleClick:(id)sender {
    if (!isShown) {
        _cautionView.frame =  CGRectMake(130, 20, 0, 0);
        [UIView animateWithDuration:0.25 animations:^{
            _cautionView.frame =  CGRectMake(130, 30, 100, 200);
        }];
        isShown = true;
    } else {
        [UIView animateWithDuration:0.25 animations:^{
            _cautionView.frame =  CGRectMake(130, 30, 0, 0);
        }];
        isShown = false;
    }
}
=> Based ON Button Click Hide And Show And Make UIView Frmae Size On
   Button Clikced:-

Use of Username And Pasword Post Method In Ios/Iphone

==> Here,  How can use of POST Method.: And Pass Parameter Username Password:

1. Use Some Like String With Actual Username And Password.

   NSString *post = [NSString stringWithFormat:@"Username=%@&Password=%@",
   @"username",@"password"];

2. PostString  That Encoding using NSASCIIStringEncoding  also

=> You Need Send That Post String To  NSData Format.


    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding
    allowLossyConversion:YES];


=> You need to send the actual length of your data. Calculate the length of
   the post string.

    NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];

3. Use Object  a UrlRequest with  Properties Like HTTP Method,

=>  HTTP Header Field With Length of
    Post String. Create URLRequest object and initialize it.

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];

 =>   Set That URL Whitch going to Send The Data To That Request.

     [request setURL:[NSURL URLWithString:

     @"http://www.abcde.com/xyz/login.aspx"]];

 =>  Now, set HTTP method (POST or GET). Write this lines as it is in your code.

     [request setHTTPMethod:@"POST"];

 =>  Set HTTP header field with length of the post data.

    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];

 => Set Also Here Encoded Value For HTTP Header:-

   [request setValue:@"application/x-www-form-urlencoded"
   forHTTPHeaderField:@"Content-Type"];


=> Set UrlRequest with PostData To HttpBody:-

    [request setHTTPBody:postData];

 4. Create URLConnection object. Initialize it Using With The URLRequest.

   NSURLConnection *conn = [[NSURLConnection alloc]
   initWithRequest:request  delegate:self];

=> It returns the initialized URL connection , load the data for the URL request.
   You can check URL connection Based On Below Code  if/else statement as below.


    if(conn) {
    NSLog(@"Connection Successful");
    }  else {
    NSLog(@"Connection could not be made");
}
5.  To receive the data from the HTTP request , you can use the delegate

    methods provided by the URLConnection Class Reference.

    Delegate methods are as below.

=>// This method is used to receive the data which

   we get using post method.

- (void)connection:(NSURLConnection *)connection

didReceiveData:(NSData*)data

// This method receives the error report in case of connection is

not made to server.


- (void)connection:(NSURLConnection *)connection

didFailWithError:(NSError *)error

// This method is used to process the data after connection

has made successfully.
- (void)connectionDidFinishLoading:(NSURLConnection *)connection

Post method to send request And Response In Ios /Iphone

 ==> Here Usd some IBOUTLET Of NSUrlCOnnection and
==> Used Some NsmutableData Object Using it Work it.

@property (retain, nonatomic) NSURLConnection *connection;
@property (retain, nonatomic) NSMutableData *receivedData;


==> Use this method to post some

-(void)postMethod
{
    [self.connection cancel];

    //initialize new mutable data

    NSMutableData *data = [[NSMutableData alloc] init];

    self.receivedData = data;

    //initialize url that is going to be fetched.

    NSURL *url = [NSURL URLWithString:@"http://192.168.0.176/idictionary/index.php?r=login"];

    //initialize a request from url

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[url standardizedURL]];

    //set http method

    [request setHTTPMethod:@"POST"];

==> Here  data whitch Using Post Data

    NSString *postData = @"mac_id=val2&email_id=abc@gmail.com&password=abcfggkjhkj";


==>Here You Heve to Give To Some Parameter Vakue That You Want:

    //set request content type we MUST set this value.

    [request setValue:@"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

    //set post data of request

    [request setHTTPBody:[postData dataUsingEncoding:NSUTF8StringEncoding]];

    //initialize a connection from request

    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

    self.connection = connection;
    //start the connection

    [connection start];

}
==> Add Some Deleget file Of Method And Action Which Help it.

/*

=> this method might be calling more than one times according to incoming data size
 */

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{

    [self.receivedData appendData:data];
}
/*

 if there is an error occured, this method will be called by connection
 */

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
    NSLog(@"%@" , error);
}
/*

==>  if data is successfully received, this method will be called by connection

 */
-(void)connectionDidFinishLoading:(NSURLConnection *)connection{

    //initialize convert the received data to string with UTF8 encoding

    NSString *htmlSTR = [[NSString alloc] initWithData:self.receivedData

                                              encoding:NSUTF8StringEncoding];

   // NSLog(@"%@" , htmlSTR);
    NSError *e = nil;
    NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData: self.receivedData options:
    NSJSONReadingMutableContainers error: &e]; <== Here used One Parser Called   SBJson Prser

    NSLog(@"data %@",jsonArray);  <== here Some OutPut Display

    //show controller with navigation
}

Push viewController from code and storyboard In Ios

PlaceViewController *newView = 

 [self.storyboard instantiateViewControllerWithIdentifier:

@"storyBoardIdentifier"];
[self.navigationController pushViewController:newView animated:YES];

For Storyboards, you should use performSegueWithIdentifier like so:  [self performSegueWithIdentifier:@"identifier goes here" sender:self];
