UISearchBar ios 7在取消时崩溃

Question

我正在使用UITableViewController，在表添加的搜索栏的标题视图中。在iOS 6中搜索和取消按钮对我来说很好，但在iOS 7搜索工作正常，当我点击取消按钮应用程序崩溃时，以下消息。

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Auto Layout still required after executing -layoutSubviews. UITableView's implementation of -layoutSubviews needs to call super.'

libc++abi.dylib: terminating with uncaught exception of type NSException

我正在使用故事板和默认取消按钮。

请帮助解决这个问题。谢谢。

Answer 1

取消选中使用AutoLaout字段并尝试再次运行，请参见下图：

Answer 2

UITableView's implementation of -layoutSubviews needs to call super.

我认为这是问题。

检查所有UITableView的layoutSubviews实现，添加[super layoutSubviews];。

- (void)layoutSubviews{
    [super layoutSubviews];
    //to do other things
}
