检查从Swift中的UILocalNotification启动

这是 How to check launchOptions in Swift?的后续问题 – 我的应用程序在没有崩溃的情况下成功启动,但我似乎无法正确检测应用程序何时从通知启动到正常启动.

我正在创建我的UIlocalnotification：

// set up a frequently recurring notification here just for testing...
var fast = UIlocalnotification()
fast.fireDate = NSDate(timeIntervalSinceNow: 15)
fast.alertBody = "Alert Message"
fast.timeZone = NSTimeZone.localTimeZone()
fast.repeatInterval = NSCalendarUnit.CalendarUnitMinute
fast.userInfo = ["Important":"Data"]
UIApplication.sharedApplication().schedulelocalnotification(fast)

这是我从UIlocalnotification启动应用程序时尝试处理的代码.

func application(application: UIApplication!,didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
    if var launch = launchOptions {
        if var key = launch.objectForKey(UIApplicationLaunchOptionslocalnotificationKey) {
            // I never seem to reach this point...
        }
    }
    return true
}

如果我的应用程序是后台运行的,我点击警告框,我想要触发的操作正确执行,所以我知道我至少可以使一条路径正常工作.这里的问题是完全从通知启动应用程序.

解决方法

如果您的应用程序在后台运行,则不会调用“application didFinishLaunching”方法.它已经推出.

在这种情况下,您应该在“application didReceivelocalnotification”方法中完成工作.

func application(application: UIApplication!,didReceivelocalnotification notification: UIlocalnotification!) {
        // do your jobs here
}
