UISearchController上的“取消”按钮有时不起作用

Question

I am facing an issue with the UISearchController in iOS 8. The problem is that whenever I am clicking on cancel button, instead of cancelling the search operation, it is bringing up the keyboard. Follow below steps to reproduce the issue -

1. Click on the search bar.
2. Type a word and click on search(This will dismiss the keyboard)
3. Now click on cancel.

Now, instead of dismissing the search, the keyboard is popping up for entering the text. This usually happens when I am tapping at the right half of cancel button and it can be reproduced even in standard iOS apps like Contacts app. I would like to dismiss search when cancel is tapped.

Is there any workaround for this issue?

单击取消按钮时，可以通过编程方式删除搜索栏作为第一响应者，以防止键盘弹起。

[searchController.textField resignFirstResponder];
