Click Event on UIImageView programmatically in ios

Question

I am displaying a image from code here is the code

UIImageView *preArrowImage =[[UIImageView alloc]init ]; preArrowImage.image =[UIImage imageNamed:@"arrowprev.png"]; preArrowImage.frame = CGRectMake(20, 60, 10, 30); [self.view addSubview:preArrowImage]; 

I want to handle the touch event on the preArrowImage programmatically.

Answer 1

SWIFT 5

let preArrowImage : UIImageView // also give it frame let singleTap = UITapGestureRecognizer(target: self, action: #selector(tapDetected)) preArrowImage.isUserInteractionEnabled = true preArrowImage.addGestureRecognizer(singleTap)  //Action  func tapDetected() {     print("Imageview Clicked") } 

Objective-c

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapDetected)]; singleTap.numberOfTapsRequired = 1; [preArrowImage setUserInteractionEnabled:YES]; [preArrowImage addGestureRecognizer:singleTap];   -(void)tapDetected{     NSLog(@"single Tap on imageview");   } 

Answer 2

Simply add a UITapGesture on the image but remember to make its UserInteraction Enabled.

    UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self      action:@selector(singleTapGestureCaptured:)];     [preArrowImage addGestureRecognizer:singleTap];     [preArrowImage setMultipleTouchEnabled:YES];     [preArrowImage setUserInteractionEnabled:YES];
