问题 Here's my problem. Am Using a scrollview whose Frames I am changing when rotating the device. I have 8 AsyncImageView on that scrollview. And the Images on AsyncImageView's are set by calling web services. Project runs fine. Images on the AsyncImageView are loaded properly.

问题 as shown in the picture below the UIPanGestureRecognizer will not pan when the drag started inside the "dead zone" on the top of the screen. This is most likely caused by the notification center. The touchesMoved:withEvent: method however does get called, so there should be a way to get pan gestures recognized in this area.

问题 I have a weird issue: I have a UIScrollView whose background is transparent. Inside of it there are a few UILabels also with a transparent background and with a custom font.

This does not happen if i set an opaque background to the labels. Do you have any idea what might be causing this? 回答1: This sounds like you may be adding

问题 I have a UIScrollView with horizontal pagination - similar to the weather app. Under certain circumstances, I want to prevent the user from scrolling horizontally. Simply disabling the scrolling is a little jarring - I would prefer to duplicate the experience of scrolling past the last page - a little scrolling is permitted, but since there is no more content, the scrollview bounces back. How might I go about implementing this? Should I be changing the contentSize of the ScrollView? How do I

问题 I've put a ScrollView in storyboard. Next, in the code I call self.scroll.frame = CGRectMake(100, 0, 800, 900); I suppose the scroll should change the position into (100, 0) But somehow it still remains in the original position where was set in storyboard. What am I missing ? 回答1: Yes it won't work for any view in autolayout system at all if added using storyboard or xib. If you want to set frame initialise in your code. @property (nonatomic,strong) UIScrollView *scrollView; _scrollView = [
