无法移动键盘视图iOS9 swift [英] Can't move keyboard view iOS9 swift

问题描述

我需要实现一个不屑一顾的键盘（向下滑动以解除），就像在iOS上的股票消息应用程序中那样。

I need to implement a dismissive keyboard (swiping down to dismiss) like the one in the stock messages app on iOS.

我有这个代码来获取键盘查看：

I have this code to get the keyboard view:

func keyboardWillShowWithNotification(notification:NSNotification) {
    let keyboardView = accessoryView.superview
}  

我连接了tableView的UIPanGestureRecognizer，以检测我何时需要开始移动键盘。

And I connected the UIPanGestureRecognizer of the tableView to detect when I need to start moving the keyboard down.

func handleTableViewPan(gr:UIPanGestureRecognizer) {

   let location = panGestureRecognizer.locationInView(self.view)
   let offset = ... //calculated correctly
   keyboardView.frame.origin.y = originalKeyboardFrame.origin.y + offset
}

这个方法适用于iOS 8，但是对于iOS 9，似乎键盘保持不变，所以我无法移动它。
也许有人遇到了同样的问题，可以帮助我。
谢谢。

The method worked fine with iOS 8 but with iOS 9 it seems like the keyboard is hold in place a little different so I can't move it. Maybe someone encountered the same problem and can help me. Thank you.

推荐答案

在iOS 9中有一个名为UIRemoteKeyboardWindow的键盘新窗口，所以当你使用accessoryView.superview你会得到一个错误的视图。

In iOS 9 there is a new window for keyboard named UIRemoteKeyboardWindow, so when you are using accessoryView.superview you will get a wrong view.

要获得正确的视图，请尝试直接从窗口层次结构中找到它：
（objective-c code）

To get correct view try to find it from window hierarchy directly: (objective-c code)

-(UIView*)getKeyboardInputView {
    if([[UIDevice currentDevice].systemVersion floatValue] >= 9.0) {
        for(UIWindow* window in [[UIApplication sharedApplication] windows])
            if([window isKindOfClass:NSClassFromString(@"UIRemoteKeyboardWindow")])
                for(UIView* subView in window.subviews)
                    if([subView isKindOfClass:NSClassFromString(@"UIInputSetHostView")])
                        for(UIView* subsubView in subView.subviews)
                            if([subsubView isKindOfClass:NSClassFromString(@"UIInputSetHostView")])
                                return subsubView;
    } else {
        return accessoryView.superview;
    }
    return nil;
}
