IOS UITextField 跳转到搜索界面

利用下面的代码，当UITextField 输入框中焦点停留时，立刻跳转到搜索页面中，进行搜索处理。

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if (textField ==
_searchTextField)
{
SearchViewController *_followSearchViewController = [[SearchViewController
alloc]init];
[self.navigationController
pushViewController:_followSearchViewController
animated:YES];
}

return
YES;
}

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
[self
resignTextResponder];
}
