NumberKeyPad中的完成按钮导致iOS 8中出现问题

Question

代码用于在Numberkeypad

中添加完成按钮

- (void)keyboardWillShow:(NSNotification *)note {
    // create custom button
    doneButton = [[UIButton alloc]init];
    doneButton.frame = CGRectMake(0, 163, 106, 53);
    doneButton.adjustsImageWhenHighlighted = NO;
    [doneButton setTitle:@"Done" forState:UIControlStateNormal];
    [doneButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

    [doneButton addTarget:self action:@selector(done) forControlEvents:UIControlEventTouchUpInside];

    if (IS_iOS_7_OR_LATER) {
        dispatch_async(dispatch_get_main_queue(), ^{
            UIView *keyboardView = [[[[[UIApplication sharedApplication] windows] lastObject] subviews] firstObject];
            [doneButton setFrame:CGRectMake(0, keyboardView.frame.size.height - 53, 106, 53)];
            [keyboardView addSubview:doneButton];
            [keyboardView bringSubviewToFront:doneButton];

            [UIView animateWithDuration:[[note.userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] floatValue]-.02
                                  delay:.0
                                options:[[note.userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]
                             animations:^{
                                 self.view.frame = CGRectOffset(self.view.frame, 0, 0);
                             } completion:nil];
        });
    }else {
        // locate keyboard view
        dispatch_async(dispatch_get_main_queue(), ^{
            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:@"UIKeyboard"] == YES)
                    [keyboard addSubview:doneButton];
            }
        });
    }
}

我已编写代码在数字键盘中添加完成按钮，它与设备的默认键盘完美配合，如果设备安装了第三方键盘，则会出现问题[快捷键App]是否有办法识别第三方键盘要解决这个问题

提前致谢！

如果你愿意，我知道一种方式，但你不是说的; 您不需要任何第三方库来使用此方法 你只需创建UIBarButton并向UIToolbar添加按钮，最后只需在实现后添加创建的工具栏

YourNumberTextField.inputAccessoryView = textFieldToolBar;

这是一个代码

UIToolbar* textFieldToolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
textFieldToolBar.barStyle = UIBarStyleBlackTranslucent;
textFieldToolBar.items = [NSArray arrayWithObjects:
                       [[UIBarButtonItem alloc]initWithTitle:@"Clear All" style:UIBarButtonItemStyleBordered target:self action:@selector("YourClearButtonFunctionName")],
                       [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
                       [[UIBarButtonItem alloc]initWithTitle:@"Ok!" style:UIBarButtonItemStyleDone target:self action:@selector("YourOkButtonFunctionName")],
                       nil];
[textFieldToolBar sizeToFit];
YourNumberTextField.inputAccessoryView = textFieldToolBar;
