我正在尝试按照Parse指南来处理我以Json格式发送的通知,但我遇到了问题,这是我的代码：
func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
// Override point for customization after application launch.
Parse.setApplicationId("MyAppId",clientKey: "MyAppClientKey")
var notificationType: UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.sound
var settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationType,categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()
if let launchOptions = launchOptions {
var notificationPayload: NSDictionary = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as NSDictionary!
println(launchOptions)
var url = notificationPayload["url"] as String
var Feed: FeedTableViewController = FeedTableViewController()
Feed.messages.insert(url,atIndex: 0)
Feed.sections.insert("section",atIndex: 0)
}
return true
}
该应用程序现在不会崩溃,但我所做的更改不会发生.
Json代码：
{
"aps": {
"badge": 10,"alert": "Test","sound": "cat.caf"
},"url": "http://www.google.com"
}
解决方法
我猜你的问题在这里：
launchOptions(UIApplicationLaunchOptionsRemoteNotificationKey) as NSDictionary
我不确定你在期待什么,但据我所知,在字典上没有这样的方法.您可能正在寻找下标语法.像这样的东西：
launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as NSDictionary
要获取嵌套在键下的launchOptions字典中的字典：UIApplicationLaunchOptionsRemoteNotificationKey.
话虽这么说,launchOptions可能是零,你应该在你的代码中添加该检查,并尝试记录launchOptions并在此处发布结果.
您可以检查launchOptions是否为零：
if let launchOpts = launchOptions {
var notificationPayload: NSDictionary = launchOpts.objectForKey(UIApplicationLaunchOptionsRemoteNotificationKey) as NSDictionary
}
