突然我的應用程序無法生成設備令牌。 我創建了一個應用程序來接收遠程推送通知,應用程序運行良好,但今天我的應用程序不生成設備令牌,我在xcode上運行代碼並且不生成令牌。沒有委託方法調用。 我不改變任何東西,不工作更多。函數didRegisterForRemoteNotificationsWithDeviceToken不工作。看:我的應用程序無法生成設備令牌
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
print(deviceToken)
}
不打印什麼
這個函數什麼也不做:
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
print(error)
}
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
// Override point for customization after application launch.
let types:UIUserNotificationType = [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound]
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: types, categories: [newsCategory]))
return true
}
爲什麼這個問題呢?我該如何解決它?
