didReceiveRemoteNotification未在后台模式中调用

Question

我正在处理推送通知,我收到的数据是JSON格式.如何解析JSON数据,如下面的通知中心所示:

Answer 1

如果你的应用程序在后台/前台模式下调用此方法

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler

如果您使用上述方法,您将在控制台中遇到以下错误

application:didReceiveRemoteNotification:fetchCompletionHandler:],但您仍需要将"remote-notification"添加到Info.plist中支持的UIBackgroundModes列表中.

解决此问题

按照步骤的图像

如果你的app在前台模式下调用此方法

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo

选择no-2

   - (void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
  UIApplicationState state = [application applicationState];
    // user tapped notification while app was in background
if (state == UIApplicationStateInactive || state == UIApplicationStateBackground) {
     // go to screen relevant to Notification content
} else {
     // App is in UIApplicationStateActive (running in foreground)
     // perhaps show an UIAlertView
}
}

迅速

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
var state: UIApplicationState = application.applicationState()
// user tapped notification while app was in background
if state == .Inactive || state == .Background {
    // go to screen relevant to Notification content
}
else {
    // App is in UIApplicationStateActive (running in foreground)
    // perhaps show an UIAlertView
}
}
