Answer 1

第一套textfield委託在viewDidLoad這樣..

self.textfield.delegate=self; 

然後用這個方法。

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

    [textField resignFirstResponder]; 
    return YES; 
    } 

Answer 2

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

這應該這樣做，如果你設置了delegate在視圖控制器的textField。
