Objective-C

In your viewDidLoad: method write this:

-(void)viewDidLoad {

    UIImageView *imageview = [[UIImageView alloc]initWithFrame:CGRectMake(100.0, 100.0, 100.0, 100.0)];
    [imageview setImage:[UIImage imageNamed:@"image.png"]];
    [imageview setUserInteractionEnabled:YES];

    UITapGestureRecognizer *singleTap =  [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapping:)];
    [singleTap setNumberOfTapsRequired:1];
    [imageview addGestureRecognizer:singleTap];

    [self.view addSubview:imageview];
}

Then call your gesture method like this:

-(void)singleTapping:(UIGestureRecognizer *)recognizer {
    NSLog(@"image clicked");
}

Swift

override func viewDidLoad() {
    super.viewDidLoad()

    let imageView: UIImageView = UIImageView(frame: CGRect(x: 100.0, y: 100.0, width: 100.0, height: 100.0))
    imageView.image = UIImage(named: "image.png")
    imageView.isUserInteractionEnabled = true

    let singleTap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.singleTapping(recognizer:)))
    singleTap.numberOfTapsRequired = 1
    imageView.addGestureRecognizer(singleTap)

    self.view.addSubview(imageView)
}

@objc func singleTapping(recognizer: UIGestureRecognizer) {
    print("image clicked")
}
