Click Event on UIImageView programmatically in ios

Now in Swift!

let singleTap = UITapGestureRecognizer(target: self, action: Selector("tapDetected"))
singleTap.numberOfTapsRequired = 1

preArrowImage.userInteractionEnabled = true
preArrowImage.addGestureRecognizer(singleTap)


//Action
func tapDetected() {
    println("Single Tap on imageview")
}

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];

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");
  }

Swift 3

On UIImageView enable UserInterAction

 override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesEnded(touches, with: event)

        if let touch = touches.first {
            if touch.view == self.imgVwPostPreview { //image View property

                //Do your actions
                //self.delegate?.didClickOnCellImageView(indexPath: self.cellIndexPath!)
            }
        }
    }
