UITapGestureRecognizer not working in UIImageView

Question

I had the following code:

UITapGestureRecognizer *showStoryTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showNewsStory         


        

Answer 1

UIImageView has user interaction disabled by default, unlike most other UIView subclasses in UIKit.

Answer 2

    use lazy var instead of let . Here is an example.

    lazy var loginSignUpView: LoginSignUpView = {
            let lsv = LoginSignUpView()
            lsv.loginRegisterButton.addTarget(self, action: #selector(handleLoginRegistrationButton), for: .touchUpInside)
            lsv.segmentedControlForLoginRegister.addTarget(self, action: #selector(handleSegmentedControlForLoginRegister), for: .valueChanged)
            lsv.profileImageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleSelectProfileImageView)))

            return lsv
        }()


@objc func handleSelectProfileImageView() {
        print("Image tapped")
    }

Answer 3

objective-c ios 10

UITapGestureRecognizer *oneTouch=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(OneTouchHandeler)];

[oneTouch setNumberOfTouchesRequired:1];

[imageView addGestureRecognizer:oneTouch];

imageView.userInteractionEnabled = YES;

// swift 3.0

   let oneTouch = UITapGestureRecognizer(target: self, action: #selector(self.OneTouchHandeler(_:)))

imageView.addGestureRecognizer(oneTouch)

imageView.isUserInteractionEnabled = true
