RxSwift: How to add gesture to UILabel?

Swift 5 (using RxGesture library).

Best and simplest option imho.

     label
        .rx
        .tapGesture()
        .when(.recognized) // This is important!
        .subscribe(onNext: { [weak self] _ in
            guard let self = self else { return }
            self.doWhatYouNeedToDo()
        })
        .disposed(by: disposeBag)

Take care! If you don't use .when(.recognized) the tap gesture will fire as soon as your label is initialised!

A UILabel is not configured with a tap gesture recognizer out of the box, that's why RxCocoa does not provide the means to listen to a gesture directly on the label. You will have to add the gesture recognizer yourself. Then you can use Rx to observe events from the recognizer, like so:

let disposeBag = DisposeBag()
let label = UILabel()
label.text = "Hello World!"

let tapGesture = UITapGestureRecognizer()
label.addGestureRecognizer(tapGesture)

tapGesture.rx.event.bind(onNext: { recognizer in
    print("touches: \(recognizer.numberOfTouches)") //or whatever you like
}).disposed(by: disposeBag)
