我正在开发 SDK 并 try catch 应用程序终止 Notification
。很容易将其作为(例如)NSNotification.Name.UIApplicationWillResignActive
self.resignActiveNotification = NotificationCenter.default.addObserver(forName: NSNotification.Name.UIApplicationWillResignActive,
object: nil,
queue: nil) { _ in
//something goes here and it works like a charm.
}
所以我想有类似的终止行为:
self.terminateNotification = NotificationCenter.default.addObserver(forName: NSNotification.Name.UIApplicationWillTerminate,
object: nil,
queue: nil) { _ in
NSLog("%@",#function)
}
而且这个永远不会被调用!
当然,如果我输入 AppDelegate
:
func applicationWillTerminate(_ application: UIApplication) {
//termination
}
它会起作用,但由于我正在构建一个 SDK,我无法使用 AppDelegate 方法。有没有办法获得终止关闭调用?或者任何其他方式知道应用程序即将终止?
在 Apple documentation你可以找到:
After calling this method, the app also posts a UIApplicationWillTerminate notification to give interested objects a chance to respond to the transition.
然而这似乎被打破了
这似乎对我有用:
init() {
NotificationCenter.default.addObserver(self,
selector: #selector(applicationWillTerminate(notification),
name: UIApplication.willTerminateNotification,
object: nil)
}
@objc func applicationWillTerminate(notification: Notification) {
// Notification received.
}
deinit {
NotificationCenter.default.removeObserver(self)
}
关于ios - 应用程序将终止通知,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/49030947/
