按下远程通知时打开视图控制器

Question

我的应用允许用户向朋友发送消息。然后他们会收到推送通知。当通过通知打开应用程序时，如何通过打开传入消息来获取视图控制器？

Answer 1

为此，您需要覆盖app delegate didFinishLaunchingWithOptions函数并检查launchOptions是否包含任何通知密钥：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    if let options = launchOptions {

        if let notification = options[UIApplicationLaunchOptionsRemoteNotificationKey] as? [NSObject : AnyObject] {

            //notification found mean that you app is opened from notification
        }
    }


    return true
}
