UITextField委託

Question

我有一個UITextFiled我應用委託關閉鍵盤按「完成」。

... 
    textfield.returnKeyType = UIReturnKeyDone; 
    textfield.delegate = self; 
    .... 

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

    [textField resignFirstResponder]; 
    return YES; 
} 

如何在按「完成」時調用方法？

Answer 1

這是你想要的嗎？

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

Answer 2

當按下「完成」按鈕時，該字段的編輯將結束。您可以調用的委託方法：

textFieldDidEndEditing: 

時田辭職的第一響應狀態時調用此方法，因此它也將被稱爲當您執行textFieldShouldReturn喜歡你指定它。
