Question

I have one image view, I set the image on it. I want to open closeup view of that image by onclick of that image.
How we can achieve this? any idea

Answer 1

Firstly do this:

imageView.userInteractionEnabled = YES;

Another thing is add UIGestureRecognizerDelegate in .h of yourViewController

@interface yourViewController : UIViewController<UIGestureRecognizerDelegate>
#import <QuartzCore/QuartzCore.h>

Now Add UITapGestureRecognizer in imageView.

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleImageTap:)];
    tap.cancelsTouchesInView = YES;
    tap.numberOfTapsRequired = 1;
    tap.delegate = self;
    [imageView addGestureRecognizer:tap];
    [tap release];

// handle method
- (void) handleImageTap:(UIGestureRecognizer *)gestureRecognizer {
   // your closeup view here on image click
   UIImageView *imgPopView = [UIImageView alloc]initWithFrame:self.view.frame];
   // Add image in imgPopView
   [self.view addSubView:imgPopView];

   // instantaneously make the image view small (scaled to 1% of its actual size)
   imgPopView.transform = CGAffineTransformMakeScale(0.01, 0.01);
  [UIView animateWithDuration:0.4 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
    // animate it to the identity transform (100% scale)
    iimgPopView.transform = CGAffineTransformIdentity;
  } completion:^(BOOL finished){
    // if you want to do something once the animation finishes, put it here
  }];

}
