使用导航控制器推动后,UIScrollView滚动不起作用 [英] UIScrollView scroll not working after pushed with a navigation controller
问题描述
我有一个奇怪的问题.我在视图层次结构的一部分中有一个UIScrollView.当通过UITabBarController呈现视图时,它工作得很好,但是在使用Navigation控制器将视图推入视图后,它根本不起作用(这是将第三个vc推到根目录之上).滚动视图是在情节提要中创建的,并且以下行位于viewDidAppear方法中:
I'm having an odd problem. I have a UIScrollView in a part of view hierarchy. It's working just fine when the view is presented via UITabBarController, but doesn't work at all after it is pushed with a Navigation controller (it is the third vc pushed atop the root). The scroll view was created in storyboard and the following lines are in the viewDidAppear method:
[super viewDidAppear:animated];
[self.scrollView setScrollEnabled:YES];
self.scrollView.contentSize = CGSizeMake(320.0f, 468.0f);
有什么想法或建议吗?如果您需要滚动视图属性检查器的照片,请告诉我.这是调用方法.该错误可能在此处某处.
Any ideas, or suggestions? If you need shots of scrollview attributes inspector let me know. Here's the call method. The error might be somewhere inside here.
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main_iPhone"
bundle:nil];
MKontaktViewController *vc = [sb instantiateViewControllerWithIdentifier:@"Kontakt"];
vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self.navigationController pushViewController:vc
animated:YES];

推荐答案
如果您在viewDidLayoutSubview函数中调整滚动视图内容的大小,它将再次起作用.
If you resize the scroll view content size in the viewDidLayoutSubview function it will work again.
- (void) viewDidLayoutSubviews {
[self resizeScrollViewContent];
}
