uiswipegesturerecognizer

问题 Note: This is the iOS 13 beta, but also could apply to the official release tomorrow. Update 2: I replaced it with a larger thumb image, and I'm still having a problem. Update: It looks like it still controls continuously if I'm super precise about touching the thumb on the slider. But why is this changed, and how can I make it control like before? I have a swipe gesture recognizer added to my view: let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self

问题 I am creating a Share extension and faced with a strange behaviour during my tests on iOS 13.0 and later. I use UISwipeGestureRecognizer to interpret user's swiping gestures on the main view on my extension. This simple code provides below as an example of that I want and works perfectly on 12.4 and older: @interface ShareAndSwipeRootController () @end @implementation ShareAndSwipeRootController - (void)loadView { [super loadView]; [self.view setBackgroundColor:[UIColor redColor]]; [self.view

问题 Right Now I am making an iOS app and I would like to implement the ability to remove letters in a UILabel by simply "Dropping the letter". The part That I am having an issue with is adding a gesture recognizer to individual letters of a UILabel. I have already searched the web for this and have nothing.Just to be clear, I am NOT adding a gesture recognizer to the whole label, I am only wanting to add it to individual letters. Any help is greatly appreciated. Thanks 回答1: It seems that the

问题 I am creating an app that has a user interface similar to Tinder. By this, I mean that there are three primary view controllers that can be "panned" between. The user can simply drag to move to any of the three view controllers. I have implemented something similar in my app with one important caveat: it utilizes swipe gesture recognizers and not pan gesture recognizers. The end-result looks and feels very unnatural. This is how I'd like my user interface to behave (ignore the Gecko): This is

问题 I use UISwipeGestureRecognizer and my overwritten -(void)touchesBegan...,-(void)touchesEnded...,-(void)touchesMoved... methods. It seems that touchesBegan and touchesMoved keep tracking touches untill Swipe Gesture recognized and touchesEnded is not called (same as touchesCancelled). But I need both swipe gesture recognizer and touchesEnded to do the job, how can i do it? 回答1: At first, drag and drop the Swipe Gesture Recognizer from Libraries into View. And you check off the item canceled in

问题 I have an array of images that I want to be able to swipe forward (left) to the next image, or back (right) to the previous image. When the imageList hits -1/out of range, the app crashes. I'm having trouble of figuring out the logic of how to keep it within range. Here is my code: var imageList:[String] = ["image1.jpg", "image2.jpg", "image3.jpg"] let maxImages = 2 var imageIndex: NSInteger = 1 The swipe gestures are in my viewDidLoad() method, not sure if this is the right place... :

问题 Okay so here is the problem I'm running into: I am attempting to switch from one viewController that I named MenuViewController which contains my menu (obviously). I have a separate viewController named ViewController that contains my mapView . I would like to be able to double finger swipe left from my MenuViewController over to my mapView . I'm not exactly sure where to start. Also, I am using xib files, and not the storyboard. Running iOS 6. 回答1: UISwipeGestureRecognizer *swipeLeftGesture=
