Swift
迅速
UIApplication.sharedApplication().networkActivityIndicatorVisible = true
Swift 5, Swift 4.x, Swift 3.x
斯威夫特 5、斯威夫特 4.x、斯威夫特 3.x
UIApplication.shared.isNetworkActivityIndicatorVisible = true
Update for iOS 13
iOS 13更新
It seems there will be no network indicator displayed from iOS 13.
iOS 13 似乎不会显示网络指示器。
The deprecationmessage says:
该弃用的消息说：
Provide a custom network activity UI in your app if desired.
如果需要，请在您的应用中提供自定义网络活动 UI。
