问题描述
当我在iOS 8上为我的应用添加自定义输入视图时,我遇到了问题。这在iOS 7上完全正常,但是当切换到iOS 8时,一切都失败了。
I'm having an issue when I add a custom input view to my app on iOS 8. This was working perfectly fine on iOS 7 but when switching to iOS 8 everything fails.
这是堆栈跟踪:

相关部分是前几行。有人可以解释一下吗?我正在调用的是 myTextview.inputView = keyboard
;键盘是在故事板中创建并通过IBOutlet链接的UIView。
The relevant part being the top few lines. Can someone explain this? All I'm calling is myTextview.inputView = keyboard
; Keyboard being a UIView created in the storyboard and linked via IBOutlet.
推荐答案
之前我遇到过这个问题。
I encountered this problem before.
问题:
- 你必须确保您将分配给
inputView
或inputAccessoryView
的视图不属于任何父视图。当您从ViewController中的xib创建这些视图时,默认情况下它们被设置为superview的子视图。
- You have to ensure that the view you will assign to
inputView
orinputAccessoryView
doesn't belong to any parent view. When you create these views from a xib inside a ViewController, by default they are set as subviews of a superview.
解决方案提示:
- 在视图上使用方法
removeFromSuperview
分配给inputView
或inputAccessoryView
- Use the method
removeFromSuperview
on the view you will assign toinputView
orinputAccessoryView
