UIApplication在swift3 Xcode8中没有成员keywindow

Question

我在xcode8中编写此代码，但我有错误：

Missing required parameters for [Route: resource] [URI: resource/{Resource_ID}])

但我有错误，UIApplication没有成员keywindow

我该怎么做！？

Answer 1

经过大量搜索后我发现它如何解决：

if let window = UIApplication.shared.delegate?.window {
            let blackView = UIView()
            blackView.backgroundColor = UIColor.black
            window?.addSubview(blackView)
            blackView.frame = (window?.frame)!

        }

SOLVE：

  

shared.delegate.window

而不是

  

sharedApplication.keywindow

和

blackView.frame = window.frame

将其更改为

blackView.frame = (window?.frame)!

Answer 2

解决:(斯威夫特3）

if let window = UIApplication.shared.keyWindow {
            let blackView = UIView()
            blackView.backgroundColor = UIColor.black

            window.addSubview(blackView)
            blackView.frame = window.frame
}
