  • UIKeyboardTypeNumberPad 数字键盘添加完成按钮

    一:添加通知

     //数字键盘添加完成

        [[NSNotificationCenterdefaultCenter] addObserver:selfselector:@selector(keyboardWillShow:) name:UIKeyboardDidShowNotificationobject:nil];

    二:数字键盘出现添加

    //键盘处理
    - (void)keyboardWillShow:(NSNotification *)note
    {
        UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
        doneButton.frame = CGRectMake(15, 172, 65, 35);
        //doneButton.frame = CGRectMake(8, 163, 50, 30);
    
        //[doneButton setTitle:@"完成" forState:UIControlStateNormal];
        [doneButton setBackgroundImage:[UIImage imageNamed:@"pickerBackIMG.png"] forState:UIControlStateNormal];
        [doneButton addTarget:self action:@selector(doneBtn) forControlEvents:UIControlEventTouchUpInside];
        
        UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
        UIView* keyboard;
        for(int i=0; i<[tempWindow.subviews count]; i++) {
            keyboard = [tempWindow.subviews objectAtIndex:i];
            // keyboard view found; add the custom button to it
            if(([[keyboard description] hasPrefix:@"<UIPeripheralHostView"] == YES) ||(([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES)))
                    [keyboard addSubview:doneButton];
        }
    }
    
    - (void)doneBtn
    {
        [phoneNumTextField resignFirstResponder];
    
    }
    

      三:移除通知

    - (void)dealloc

    {

        [[NSNotificationCenterdefaultCenter]removeObserver:selfname:UIKeyboardDidShowNotificationobject:nil];

        [kDatePickerrelease];

        [super dealloc];

    }
