如何在swift中显示之前检查推送通知？
我想要检查数据，如果数据不正确，我不想要显示通知
更新代码
我的代码：
我只是使用简单的Parse.com示例。这是我的AppDelegate类
import Parse
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {
var window: UIWindow?
var singInCallback: (()->())?
let defaults = NSUserDefaults.standardUserDefaults()
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
Parse.setApplicationId("//",
clientKey: "//")
// Register for Push Notitications
if application.applicationState != UIApplicationState.Background {
// Track an app open here if we launch with a push, unless
// "content_available" was used to trigger a background push (introduced in iOS 7).
// In that case, we skip tracking here to avoid double counting the app-open.
let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
var pushPayload = false
if let options = launchOptions {
pushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil
}
if (preBackgroundPush || oldPushHandlerOnly || pushPayload) {
PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
}
}
var notificationActionAccept :UIMutableUserNotificationAction = UIMutableUserNotificationAction()
notificationActionAccept.identifier = "FIRST_ACTION"
notificationActionAccept.title = "Įvertinti"
var notificationCategory:UIMutableUserNotificationCategory = UIMutableUserNotificationCategory()
notificationCategory.identifier = "CallNotificationCategory"
notificationCategory .setActions([notificationActionAccept], forContext: UIUserNotificationActionContext.Default)
let settings = UIUserNotificationSettings(forTypes: [.Alert, .Sound, .Badge], categories: NSSet(array:[notificationCategory]) as! Set<UIUserNotificationCategory>)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()
// check if app opened because user tapped on notification
if let launchOptions = launchOptions as? [String : AnyObject] {
if let notificationDictionary = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as? [NSObject : AnyObject] {
self.application(application, didReceiveRemoteNotification: notificationDictionary)
}
}
return
}
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool
{
return
}
func applicationWillResignActive(application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}
func applicationDidEnterBackground(application: UIApplication) {
}
func applicationWillEnterForeground(application: UIApplication) {
// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(application: UIApplication) {
}
func applicationWillTerminate(application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let installation = PFInstallation.currentInstallation()
installation.setDeviceTokenFromData(deviceToken)
installation.saveInBackground()
}
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
if error.code == 3010 {
print("Push notifications are not supported in the iOS Simulator.")
} else {
print("application:didFailToRegisterForRemoteNotificationsWithError: %@", error)
}
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
print(userInfo)
PFPush.handlePush(userInfo)
if application.applicationState == UIApplicationState.Inactive {
PFAnalytics.trackAppOpenedWithRemoteNotificationPayload(userInfo)
}
}
