从iOS 8.3中无法使用的数字键盘上的自定义"完成"按钮接收通知

Question

我已经使用其他线程中发布的解决方案向数字小键盘添加了一个自定义的"完成"按钮,就像这个.随着iOS 8.3的更新,一些东西已经改变,因为按钮仍然出现,但触摸通知永远不会触发.将按钮从键盘视图移动到超级视图会破坏按钮的位置,但会证明控件工作的通知.

它的行为类似于自定义按钮位于键盘上的透明层后面,并且无法进行任何触摸.

- (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];
            }
        }
    }
}
}

我遇到了同样的问题，我通过直接在 UITextEffectsWindow 上添加按钮解决了这个问题。我还更改了按钮框架。

- (void)addButtonToKeyboar {
// create custom button
self.doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.doneButton.frame = CGRectMake(0, [[UIScreen mainScreen] bounds].size.height - 53, [[UIScreen mainScreen] bounds].size.width / 3, 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];
UIButton* donebtn = (UIButton*)[tempWindow viewWithTag:67123];
if (donebtn == nil)//to avoid adding again and again as per my requirement (previous and next button on keyboard)
    [tempWindow addSubview:self.doneButton]; }
