What to use instead of UIScreen.mainScreen().applicationFrame for swift in ios 9.1?
提问by Jennifer
This might be a simple question but since I'm a beginner, it is best to ask.
这可能是一个简单的问题，但由于我是初学者，最好问一下。
As the title says what should I use instead of UIScreen.mainScreen().applicationFramesince it's deprecated in 9.0.
正如标题所说，我应该使用什么来代替， UIScreen.mainScreen().applicationFrame因为它在 9.0.0 中已被弃用。
If possible it would be great if you can provide me with a sample or example ,since I find Apples document difficult.
如果可能的话，如果您能向我提供样本或示例，那就太好了，因为我发现 Apples 文档很困难。
Currently I use the code below but I wish to change it to the new version. I would love to hear from you!
目前我使用下面的代码，但我希望将其更改为新版本。我很想听听你的意见！
let sizeRect = UIScreen.mainScreen().applicationFrame
let posX = arc4random_uniform(UInt32(sizeRect.size.width))
let posY = arc4random_uniform(UInt32(sizeRect.size.height))
Enemy.position = CGPoint(x: CGFloat(posX), y: CGFloat(posY))

Use
用
let rect1 = UIScreen.mainScreen().bounds // Returns CGRect
let rect2 = UIScreen.mainScreen().bounds.size // Returns CGSize

I know that UIScreen.mainScreen().boundsis the recommended alternative; however, it's not the exact equivalent to UIScreen.mainScreen().applicationFrame, particularly when your application does NOT occupy the whole screen, which happens with Split View and Slide Over feature on certain iPads.
我知道这UIScreen.mainScreen().bounds是推荐的替代方案；但是，它并不完全等同于UIScreen.mainScreen().applicationFrame，尤其是当您的应用程序不占据整个屏幕时，某些 iPad 上的分屏浏览和侧滑功能会发生这种情况。
In that case, this is a good alternative:
UIApplication.sharedApplication.keyWindow.frame. (of course keyWindowhas to be available, that is, you did invoke makeKeyAndVisible)
在这种情况下，这是一个不错的选择：
UIApplication.sharedApplication.keyWindow.frame. （当然keyWindow必须可用，也就是说，你确实调用了makeKeyAndVisible）

As of swift 3 you need to use it like this now.
从 swift 3 开始，您现在需要像这样使用它。
let SCREEN_WIDTH = UIScreen.main.bounds.size.width
let SCREEN_HEIGHT = UIScreen.main.bounds.size.height

For:
为了：
let width = UIScreen.mainScreen().bounds.width
and for:
和：
let height = UIScreen.mainScreen().bounds.height
