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");
  }
