iPhone操作系统：点击状态栏滚动到顶部不工作后删除/添加 [英] iPhone OS: Tap status bar to scroll to top doesn't work after remove/add back

问题描述

使用此方法隐藏状态列：

Using this method to hide the status bar:

[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];

当将hidden设置为NO时，轻触滚动到顶部UIWebView，UITableView，无论如何）不再工作，需要重新启动应用程序以获得功能。

When setting "hidden" back to NO, the tap-to-scroll-to-top (in UIWebView, UITableView, whatever) doesn't work any more, and requires a restart of the app to get the functionality back.

这是一个错误（我提交了一个rdar无论如何）还是我错过了一步？我可能会期望这种行为，因为statusBar失去了触摸某种方式与相应的视图？

Is this a bug (I filed a rdar anyhow) or have I missed a step? Should I perhaps expect this behavior since the statusBar "loses touch" somehow with the respective view?

推荐答案

您可以尝试设置ScrollsToTop属性重新显示后为true：

You could try setting the ScrollsToTop property to true again after re-showing it:

[currentView setScrollsToTop:YES];

如果这不工作，你肯定只显示一个视图吗？如果有多个滚动视图，则会忽略scrollViewDidScrollToTop消息...

If that's not working, are you definitely only showing one view? If there is more than one scrolling view a scrollViewDidScrollToTop message is ignored...
