Keyboard 从custom'接收通知；完成'；数字键盘上的按钮在iOS 8.3中不起作用

我使用其他线程中发布的解决方案，在数字键盘上添加了一个自定义的“完成”按钮。随着iOS 8.3的更新，有些东西发生了变化，按钮仍然出现，但触摸通知从未熄灭。将按钮从键盘视图移动到superview会破坏按钮的位置，但会证明控件工作的通知

它的行为就像自定义按钮位于键盘上的透明层后面，无法进行任何触摸

- (void)addButtonToKeyboard
{
// create custom button
self.doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.doneButton.frame = CGRectMake(0, 163+44, 106, 53);
self.doneButton.adjustsImageWhenHighlighted = NO;
[self.doneButton setTag:67123];
[self.doneButton setImage:[UIImage imageNamed:@"doneup1.png"]        forState:UIControlStateNormal];
[self.doneButton setImage:[UIImage imageNamed:@"donedown1.png"] forState:UIControlStateHighlighted];

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

// locate keyboard view
int windowCount = [[[UIApplication sharedApplication] windows] count];
if (windowCount < 2) {
    return;
}

UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
UIView* keyboard;

for(int i = 0 ; i < [tempWindow.subviews count] ; i++)
{
    keyboard = [tempWindow.subviews objectAtIndex:i];
    // keyboard found, add the button

    if([[keyboard description] hasPrefix:@"<UIPeripheralHost"] == YES){
        UIButton* searchbtn = (UIButton*)[keyboard viewWithTag:67123];
        if (searchbtn == nil)//to avoid adding again and again as per my requirement (previous and next button on keyboard)
            [keyboard addSubview:self.doneButton];

    }//This code will work on iOS 8.0
    else if([[keyboard description] hasPrefix:@"<UIInputSetContainerView"] == YES){

        for(int i = 0 ; i < [keyboard.subviews count] ; i++)
        {
            UIView* hostkeyboard = [keyboard.subviews objectAtIndex:i];

            if([[hostkeyboard description] hasPrefix:@"<UIInputSetHost"] == YES){
                UIButton* donebtn = (UIButton*)[hostkeyboard viewWithTag:67123];
                if (donebtn == nil)//to avoid adding again and again as per my requirement (previous and next button on keyboard)
                    [hostkeyboard addSubview:self.doneButton];
            }
        }
    }
}
}

-（无效）添加按钮键盘
{
//创建自定义按钮
self.doneButton=[UIButton-buttonwhithtype:UIButtonTypeCustom]；
self.doneButton.frame=CGRectMake（0,163+44,106,53）；
self.doneButton.adjustsImageWhenHighlighted=否；
[self.doneButton setTag:67123]；
[self.doneButton setImage:[UIImage ImageName:@“doneup1.png”]用于状态：UIControlStateNormal]；

[self.doneButton addTarget:self action:@selector（doneButton:）for controlEvents:UIControlEventTouchUpInside]；

//找到键盘后，添加按钮
如果（[[keyboard description]hasPrefix:@“我也遇到了同样的问题，我通过直接在UITextEffectsSwindow上添加按钮解决了这个问题。我还更改了按钮框架

[临时窗口添加子视图：self.doneButton]；}
objectAtIndex:1可能不是每次都以窗口索引为目标。因此，代码应根据其描述检查窗口是否为UITextEffectsWindow，如下所示

if (windowCount < 2) {
    return;

} else {
    periodButton.frame = CGRectMake(0, [[UIScreen mainScreen] bounds].size.height - 53, 106, 53);
    for (UIWindow *window in [[UIApplication sharedApplication] windows]) {
        if ([[window description] hasPrefix:@"<UITextEffectsWindow"]) {
            [window addSubview:periodButton];
        }
    }

}

if（windowCount<2）{
返回；
}否则{
periodButton.frame=CGRectMake（0，[[UIScreen mainScreen]边界].size.height-53,106,53）；
对于（在[[UIApplication sharedApplication]窗口]中的UIWindow*窗口）{
