uiscrollview

问题 i have got a UILabel which is not static. I want to resize my scroll view so that it fits the label. Here is my idea now: self.scrollView.contentSize = CGSizeMake(320.0, 92+self.contentLabel.frame.size.height); 92 stands for pixels from where my label start. (there is a heading too) But it doesn't work, it seems to be connected with Interface Builder also. Thanks guys. 回答1: You need to set the frame as well. The contentSize of the scrollview is just what is within, not the frame of the view

问题 I was wrestling with UIScrollview and it knocked me out. I tried to take reference from following two post on stackOverFlow scrollview xcode4.5 autolayout, Xcode 4.5 UIScrollView, Embed ImageView in ScrollView with Auto Layout on iOS 6, I tried viewDidLayoutSubviews, as told in UIScrollView setContentSize breaks view with Auto Layout that is causing my app to crash. And I tried ViewDidLoad, viewDidAppear and viewWillAppear but nothing worked. I tried google and found couple more related post

问题 I am creating a view in a storyboard that has a bunch of text boxes with a button at the bottom. When I click in the text box the keyboard appears. This hides some of my text boxes. All text boxes live within the scrollview. Is there a way in storyboarding (if not then in code) to make the scrollview scroll properly amongst all the content when the keyboard appears? Do I have to dynamically change the content size when the keyboard appears, or is there a way that I can set up the scroll view

All seem to be easy and there are a lot of tutorials how to do it. But my problem that scrolling works only when I zoom in screen. Setting "contentSize" doesn't give any effect. @interface OMSScroolViewController : UIViewController <UIScrollViewDelegate> @property (strong, nonatomic) IBOutlet UIScrollView *scroll; @property (strong, nonatomic)

问题 I have a UIScrollView which has a subview UITextView. When I added text to UITextView by code, the view is scrolling to the last line. I want the view not to scroll when I add text to UITextView by code. Anyone can help me fix the problem? 回答1: Finally I can fix my problem.

问题 I am having an issue when trying to sketch on a UIView that is a child view in a UIScrollView . The problem occurs when you try to sketch on the UIView after it's been zoomed or scrolled on. It seems my sketch code (shown below) does not take into account the zoom or scale of the UIView within the UIScrollView because the lines blur and don't show up where they should. Please let me know if there is something that can be done to my code or provide another solution. - (void)touchesBegan:(NSSet
