问题描述
我遇到了一个奇怪的问题.我在视图层次结构的一部分中有一个 UIScrollView .当视图通过 UITabBarController 呈现时,它工作得很好,但在使用导航控制器推送后根本不起作用(它是第三个 vc 推送到根顶部).滚动视图是在情节提要中创建的,以下几行在 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.下面是调用方法.错误可能在这里的某个地方.
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];
谢谢,丘吉尔
推荐答案
如果你在 viewDidLayoutSubview 函数中调整滚动视图内容的大小,它会再次起作用.
If you resize the scroll view content size in the viewDidLayoutSubview function it will work again.
- (void) viewDidLayoutSubviews { [self resizeScrollViewContent]; }
