how to get image name when click on uiimageview?

I have a UIScrollview. In the UIScrollview there are 4 UIImageViews with images. When I click on any UIImageview I want to know the name of that image.

UIImageView just keeps the pointer to the place the UIImage is stored inside the memory, so it's not possible with UIImageView. You would need to create a subclass of UIImageView with a NSString variable which stores the value to access it later. Something like this:

#import <UIKit/UIKit.h>

@interface MyImageView : UIImageView

@property (strong, nonatomic) NSString *imageName;

@end

The image names are not stored in UIImage objects so you have to keep them somewhere else for lookup. To detect touches in image views you either have to subclass them and add code for touch detection, add tap recognizers or replace them with buttons.
