使用Swift和iOS 7.1进行远程通知时出错

Question

我在var setting...上遇到以下错误var setting...仅在iOS 7.1上显示以下行：

没有更多的线索了。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    var type = UIUserNotificationType.Badge | UIUserNotificationType.Alert | UIUserNotificationType.Sound;
    var setting = UIUserNotificationSettings(forTypes: type, categories: nil);
    UIApplication.sharedApplication().registerUserNotificationSettings(setting);
    UIApplication.sharedApplication().registerForRemoteNotifications();
    return true
}

在iOS 8.1和8.2上运行良好。 您能指出我该如何解决吗？

Answer 1

我在目标C中实现了以下目标，可能会对您有所帮助。

if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)]){
    // This will execute for iOS 8
    [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

    [application registerForRemoteNotifications];
}
else {
    // This will execute for iOS 7 and prior
    [application registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
}

UIUserNotificationSettings可从ios 8与registerUserNotificationSettings一起使用

您可以使用iOS 7的registerForRemoteNotificationTypes ，但需要在运行时（操作系统版本）进行检测，并使用正确的方法。
