发送本地推送通知

Question

我正在尝试使用swift，immediatelly在本地发送推送通知（读取：未安排在将来）。

我正在尝试

          var localNotification:UILocalNotification = UILocalNotification()
        localNotification.alertAction = "Testing notifications on iOS8"
        localNotification.alertBody = "Some text here"
        localNotification.fireDate = NSDate(timeIntervalSinceNow: 1)
        UIApplication.sharedApplication().scheduleLocalNotification(localNotification)

有权发送已经授予的推送通知。

虽然代码被调用，但没有发送推送通知。我做错了什么？

谢谢！

您只需将timeZone设置为localTimeZone

即可

  

根据值解释fireDate中指定的日期   这个属性。如果指定nil（默认值），则触发日期为   解释为绝对GMT时间，适用于此类情况   作为倒数计时器。如果为此分配有效的NSTimeZone对象   属性，起火日期被解释为挂钟时间   当时区发生变化时自动调整;一个   适合这种情况的例子是一个闹钟。

// App委托

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Badge, .Sound, .Alert], categories: nil))
        return true
    }

///查看控制器

import UIKit

class ViewController: UIViewController {
    var localNotification = UILocalNotification()
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        localNotification.alertAction = "Testing notifications on iOS8"
        localNotification.alertBody = "Some text here"
        localNotification.timeZone = NSTimeZone.localTimeZone()

        localNotification.fireDate = NSDate(timeIntervalSinceNow: 1)
        UIApplication.sharedApplication().scheduleLocalNotification(localNotification)

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

您已确保为您的应用注册通知（例如在AppDelegate中）。
在Objective-C中，我设法使用：

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000


    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
    [[UIApplication sharedApplication] registerForRemoteNotifications];

#else

    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

#endif

然后你的代码就会被执行。

另一件事是，如果您在前台使用应用，则可能根本看不到它们 - 请尝试通过向下滑动来打开Notification Center。

您的问题可能是您没有看到通知，但它确实存在。只需打开通知中心即可：

要检查这一点，请在AppDelegate中实施didReceiveLocalNotification方法：

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
        println("Notification done")
    }

然后，您可以处理通知并显示PopUp或任何您想要的内容。
