推荐答案

为UITextField设置一个委托对象(指向您的视图控制器)并使用方法

Set a delegate object (point to your view controller) for your UITextField and use the method

- (BOOL)textFieldShouldReturn:(UITextField *)textField

-textFieldShouldReturn将在用户点击"Go"或"Return"之前被调用.请记住返回是".

-textFieldShouldReturn will be called just before the user the user taps the "Go" or "Return". Remember to return "YES".
