问题 I have done animation opening a page on tapping on it but now I have to change it for Pan Gesture. How should I start? [UIView setAnimationDelegate:self]; [UIView commitAnimations]; CALayer *layer = ges.view.layer; CATransform3D initialTransform = ges.view.layer.transform; initialTransform.m34 = 1.0 / -1100; layer.transform = initialTransform; layer.anchorPoint = CGPointMake(-0.0, 0.5); [UIView beginAnimations:@"Scale" context:nil]; [UIView setAnimationDuration:2]; [UIView setAnimationCurve:

iOS 11 on NavigationBar pull down - height of bar changes?

问题 What I want to to: I want to drag down the whole view of a viewController to dismiss to the parent viewController using a pan gesture recognizer. The Problem: When I drag the view down, the navigationBar decreases its height and does not look good. When the view returns to its original position, the navigationBar returns to the default size. I want the navigationBar to stay at its size. I also tried to use the new large titles and some other properties of the navigationController/-bar, but

UIPanGestureRecognizer not moving object smoothly

由 一个人想着一个人 提交于 2019-12-08 05:44:36
问题 Im trying to use UIPanGestureRecognizer to move my object around, but i cannot seem to get it moving smoothly. When i move in a particular direction and change to the opposite it does not react instantly. I assume that there might be something wrong with the value, since it is positive in the "->" direction and negative in "<-". My code is following: - (void)panDetected:(UIPanGestureRecognizer *)panRecognizer { CGPoint pointA = [panRecognizer locationInView:self.view]; CGPoint pointB =

问题 I am developing an application where I have used the Pan Gesture as well as Swipe Gesture. So every time I do the Swipe Gesture but the method from the Pan Gesture is always getting called and Swipe Gesture method is not getting called. Is there any priority between all the gesture method? 回答1: You can call them in parallel by implementing the following method of the UIGestureRecognizerDelegate protocol: - (BOOL)gestureRecognizer:(UIPanGestureRecognizer *)gestureRecognizer

Using multiple UIGestureRecognizers simultaneously like UIRotationGestureRecognizer & UIPanGestureRecognizer in Swift 3

由 ≯℡__Kan透↙ 提交于 2019-12-06 13:20:17
问题 In modern user interfaces on iOS, it is often useful to implement multiple UIGestureRecognizers on a single view, in order to provide more realistic behavior of displayed objects that model the real world. For example, you might want to be able to both drag a view around the screen, but also use two fingers to rotate it. The UIGestureRecognizerDelegate provides an optional function shouldRecognizeSimultaneouslyWith for this purpose. Returning true avoids only one gesture having effect at a

This question already has answers here : Can you attach a UIGestureRecognizer to multiple views? (11 answers) Closed 4 years ago . I am working on a sample of Pan Gesture. I am keen to know that can I add single gesture on two views? My code is as follows: UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(invokePanGesture:)]; [panGesture setMinimumNumberOfTouches:1]; [panGesture setMaximumNumberOfTouches:2]; [btnGreen addGestureRecognizer:panGesture]; [btnYellow addGestureRecognizer:panGesture]; my handler method is as follows: - (void

How to allow drag UIView (PanGesture..) just in some area

由 不羁的心 提交于 2019-12-06 07:16:55
I need drag UIView via PanGestureRecognizer (I know how to do), but I can't figure out, how to make it with limitation. Need some padding from top and also if there is collision with one of four sides (left, right, top (here is the padding) and bottom of device) stop the drag and you can't over - or 1px padding like on the top, whatever. :) I tried this one: https://github.com/andreamazz/UIView-draggable but if I set the area with limitation via cagingArea, iPad (Air) is lagged. Also the moving is not smooth, I think the native PanGestureRecognizer is the best, need just the limitation area,

Slowly panning in UIPercentDrivenInteractiveTransition results in glitch

问题 In my app I'm dismissing a viewController using a UIPercentDrivenInteractiveTransition triggered by a pan gesture. I'm expecting my viewController to be dragged to the right as I'm panning it. However when I slowly pan I get a glitch: the viewController quickly jumps from left to right a bit. This can be seen here: https://youtu.be/3IEtId1w7jM Here's the code for the transition : class FilterHideTransition: UIPercentDrivenInteractiveTransition { let viewController: FilterViewController var

How to programmatically send a pangesture in swift

由 情到浓时终转凉″ 提交于 2019-12-05 18:05:09
问题 I have a view that has panGesture functionality, but I need to send a pan-gesture from one point to another programatically. Is there a way to do this in swift using an animation with a specific time interval? Here is my attempt at calling the pan gesture programmatically: var upPanPoint = CGPoint(x: contentView.center.x, y: contentView.center.y + 500) var upPan = panGestureRecognizer.setTranslation(upPanPoint, inView: self) onSwipe(upPan) here is the code that recognizes the pan gesture:

iOS: How sync two UIScrollview

I have two horizontal UIScrollview s. I want to synchronise their scrolling when user drag fingers in either of them. Here is my code: self.topScrollView = [[UIScrollView alloc] initWithFrame:CGRectZero]; self.topScrollView.delegate = self; self.topScrollView.bounces = YES; self.bottomScrollView = [[UIScrollView alloc] initWithFrame:CGRectZero]; self.bottomScrollView.delegate = self; self.bottomScrollView.bounces = YES; ... - (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView { if (scrollView == self.topScrollView) { self.bottomScrollView.delegate = nil; } else { self.topScrollView
