Use With UIPickerView And Its Source Type GalaryView In Ios/Iphone

=> Confirm Protocol Of UIimagePickerControllerDelegate:

@interface ViewController : UIViewController<UIImagePickerControllerDelegate, UINavigationControllerDelegate>

@property (weak, nonatomic) IBOutlet UIImageView *imgView;

@end

------------------------------
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

==> Here UIimage With NSData Used NSUrl:
   
    UIImage *img =[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjN0jOr9aVt9g1OIB-lfSO2lBBPvzO_I06eJ_i2x6y1TP1kPqM1t7ND_krBXO2600wwH38jrmaMpnISR2WAk6CMblXQOKsjgCqxoXC-YjG4EJIop6vN_omvttVxvrAE2gANyXv_iYA51Rk/s1600/1.png"]]];
    _imgView.image = img;
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

=> To Take Photo Action From Camera:

- (IBAction)btnTakePhotoAction:(id)sender {
    [self takePhotoMode:YES];
}
=> This Method Used For Load From GelleryView  Action In UIImagePicker:

- (IBAction)btnLoadFromGallaryAction:(id)sender {
    [self takePhotoMode:NO];
}

=> To Take Photo Mode And Check Source Type in ImagePIcker:

-(void)takePhotoMode:(BOOL)isFromCamera{
   
    if (isFromCamera && ![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
       
        UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                              message:@"Device has no camera"
                                                             delegate:nil
                                                    cancelButtonTitle:@"OK"
                                                    otherButtonTitles: nil];
       
        [myAlertView show];
        return;
       
    }
   
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = isFromCamera?UIImagePickerControllerSourceTypeCamera:UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentViewController:picker animated:YES completion:NULL];
   
}
==> Used For UIImagePickerDelegate Method And Action:-

#pragma mark - Image Picker Controller delegate methods

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
   
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    UIImage *origionalImage = [info objectForKey:UIImagePickerControllerOriginalImage];
   
   
   
    self.imgView.image = chosenImage;
    [picker dismissViewControllerAnimated:YES completion:NULL];
   
   
    [self saveImageToDouments:chosenImage];
   
}
==> Used For Save Image TO Document In UiImagePickerController:-

-(void)saveImageToDouments:(UIImage*)image{
    NSString *aStrDoc =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).lastObject;
   
    NSString *fullPath = [aStrDoc stringByAppendingPathComponent:@"sample.jpg"];
   
    NSData *imgData = UIImageJPEGRepresentation(image, 0.8);
    [imgData writeToFile:fullPath atomically:YES];
   
   
}
=> Use Action For Save Image In Gallery Using UIIMagePIckerController:-

-(void)saveImageToGallary:(UIImage*)image{
    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {   

    [picker dismissViewControllerAnimated:YES completion:NULL];
   
}
