Answer 1

首先在viewDidLoad中设置textfield的委托，如下所示。

self.textfield.delegate=self;

然后使用这个方法。

-(BOOL)textFieldShouldReturn:(UITextField *)textField
   {

    [textField resignFirstResponder];
    return YES;
   }

Answer 2

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
}

如果您已经在视图控制器中设置了textField的delegate，应该可以做到这一点。
