我试过了:
[self.tableView setScrollsToTop:YES];
但是当点击屏幕顶部时tableview仍然没有滚动到顶部.

推荐答案
您必须在层次结构中的所有其他滚动视图上将 scrollsToTop 设置为 NO.如果多个滚动视图将 scrollsToTop 设置为 YES，则在触摸状态栏时它们都不会滚动到顶部.这在 scrollsToTop 属性的文档中有所提及.
You have to set scrollsToTop to NO on all the other scroll views in your hierarchy. If more than one scroll view has scrollsToTop set to YES, none of them will scroll to top when the status bar is touched. This is mentioned in the documentation of the scrollsToTop property.
请记住，这也适用于视图层次结构中 UIScrollView 的任何子类，以及 UITableView、UIContainerView 和 >UITextView 是 UIScrollView 的子类.
Keep in mind that this also applies to any subclasses of UIScrollView in your view hierarchy, and that UITableView, UIContainerView, and UITextView are subclasses of UIScrollView.
