問題用行動表

當我顯示在textFieldDidBeginEditing動作片隱藏鍵盤，這裏是我的代碼：問題用行動表

- (void)textFieldDidBeginEditing:(UITextField *)textField { 
    // dept_label is my UITextField property 
    if (textField == dept_label) { 
     [textField setUserInteractionEnabled:YES]; // i also used dept_label instead textfield here... 
     [textField resignFirstResponder]; 
     UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Select" 
                   delegate:self 
                 cancelButtonTitle:@"OK" 
                destructiveButtonTitle:nil 
                 otherButtonTitles:@"Manpower", @"Admin",@"Research" ,nil]; 
     [actionSheet setActionSheetStyle:UIActionSheetStyleDefault]; 
     [actionSheet showInView:self.view]; 
    } 
}

問題是動作片得到激活，但鍵盤是沒有得到隱藏！

放'睡眠（0.5）;'語句之後'[文本字段resignFirstResponder];'：P –

我不認爲它的時間問題，因爲即使選擇後操作手冊中的值，鍵盤仍然是隱藏的！ – BaSha

你試過了嗎？它無論如何。如果鍵盤以前沒有隱藏。選擇UIActionSheet按鈕後，您不希望鍵盤被隱藏。 –

finally this worked.. 

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{ 
    if(textField==dept_label){   
     [textField setUserInteractionEnabled:YES]; 
     [textField resignFirstResponder]; 

      UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Select" delegate:self cancelButtonTitle:@"OK" destructiveButtonTitle:nil otherButtonTitles:@"Manpower", @"Admin",@"Research" ,nil]; 
    actionSheet.actionSheetStyle = UIActionSheetStyleDefault; 
    [actionSheet showInView:self.view];   

    }  
    return YES;  
}

使用UITextField委託這樣的：

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField { 
    if (textField == dept_label) { 
     // dept_label is my UITextField property 
     [textField setUserInteractionEnabled:YES]; 
     UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Select" 
                   delegate:self 
                 cancelButtonTitle:@"OK" 
                destructiveButtonTitle:nil 
                 otherButtonTitles:@"Manpower", @"Admin", @"Research", nil]; 
     [actionSheet setActionSheetStyle:UIActionSheetStyleDefault]; 
     [actionSheet showInView:self.view]; 
     return NO; 
    } 
    return YES; 
}

thnks omk，我試過這個，但它限制鍵盤顯示從我所有的文本字段，因爲我們返回NO，所以我稍微修改了你的代碼，現在它的工作:) – BaSha
