我试图将当前用户添加到安装类,但由于某种原因,该函数未被调用.我究竟做错了什么？我该如何解决？下面是finishlaunchingwithoptions和didregisterfornotifications.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
Parse.enableLocalDatastore()
// Initialize Parse.
Parse.setApplicationId("***********************",
clientKey: "****************************")
let settings = UIUserNotificationSettings(forTypes: [.Alert, .Sound, .Badge], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()
if let launchOptions = launchOptions as? [String : AnyObject] {
if let notificationDictionary = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as? [NSObject : AnyObject] {
self.application(application, didReceiveRemoteNotification: notificationDictionary)
}
}
return true
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
// Store the deviceToken in the current Installation …当用户a向用户b发送推送通知时,用户b将收到通知,但是一旦他们点击该通知,该通知的有效负载就会消失.相反,当用户b打开通知时,通知中的有效负载将保存为解析,因此他可以查看发送给他的所有通知.这就像是通知历史.以下是我发送通知的代码.我需要有关如何在这些通知中保存有效负载的帮助,以便用户可以查看通知历史记录.
func pushNotifications(){
let userQuery: PFQuery = PFUser.query()!
userQuery.whereKey("objectId", containedIn: Array(setOfSelectedFriends))
let pushQuery: PFQuery = PFInstallation.query()!
pushQuery.whereKey("user", matchesQuery: userQuery)
let push = PFPush()
push.setQuery(pushQuery)
push.setMessage("\(username!) wants you to meet them at \(location!)")
push.sendPushInBackgroundWithBlock {
success, error in
if success {
print("The push succeeded.")
} else {
print("The push failed.")
}
}
}
我正在使用云代码,我有两个Parse帐户.我已授权第一个Parse帐户,但我想将云代码添加到新的Parse帐户,但每当我这样做时Parse add,它会自动将我带到我已授权的解析帐户的应用程序列表中,如何启动应用程序从另一个帐户？
我有一个表情符号，我希望它是白色的，但是当我运行该程序时，它显示为红色。如何将其更改为白色？
rating.text = "\(?????)"
rating.textColor = UIColorRGB("ffffff")
