First of all you should implement UISearchBarDelegatein your class & check if you have connected the to your UISearchBaror not?
首先，您应该UISearchBarDelegate在您的班级中实施并检查您是否已将其连接到您的课程UISearchBar？
If you are adding UISearchBarthrough IB then you should select delegate property of the UISearchBar to the file's owner. You should make sure that you are connecting IBOutletfor the UISearchBarin the code properly .
如果您UISearchBar通过 IB添加，那么您应该选择 UISearchBar 的委托属性给文件的所有者。你应该确保你所连接 IBOutlet的UISearchBar代码正确。
If you are adding UISearchBarvia code then you should set the delegate yourself in the code like this searchBar.delegate=self;
如果您UISearchBar通过代码添加，那么您应该像这样在代码中自己设置委托searchBar.delegate=self;
Next step is to make sure that delegate methods are being called, which is obvious if you have connected delegate properly, best thing to check stuff is putting break pointer in your code or print through NSLog.
下一步是确保调用委托方法，如果您已正确连接委托，这很明显，检查内容的最佳方法是在代码中放置中断指针或通过NSLog.
Finally use this method to hide the keyboard if you want to hide when user clicks to search
最后，如果您想在用户单击搜索时隐藏键盘，请使用此方法隐藏键盘
- (void) searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[searchBar resignFirstResponder];
}
OR you could try when editing finished
或者你可以在编辑完成后尝试
- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar {
[searchBar resignFirstResponder];
}

Try this:
尝试这个：
Set the delegate on the search bar and check whether the IBOutlet is connected or not
在搜索栏设置delegate，检查IBOutlet是否连接
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[searchBar resignFirstResponder];
}
