ios - 为什么 didReceiveRemoteNotification :fetchCompletionHandler is called but usual didReceiveRemoteNotification isn't?

Question

在我的应用程序中，我有两种类型的推送通知:带有 content-available = 1 标志的远程静默通知和带有 body、badge< 的普通推送通知 和其他东西。

我还定义了两个委托(delegate)方法 didReceiveRemoteNotification:fetchCompletionHandler 和常用的 didReceiveRemoteNotification。

但是当没有content-available 标志的推送通知到达时，调用didReceiveRemoteNotification:fetchCompletionHandler，而不是didReceiveRemoteNotification。

如何解决这个问题？
为什么我不能为后台推送和常规推送设置两个委托(delegate)方法？

iOS 7 只调用新的，这是我在我的应用程序中处理它的方式:

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

    // Pass on
    [self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:nil];

}

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

    // Check if in background
    if ([UIApplication sharedApplication].applicationState == UIApplicationStateInactive) {

        // User opened the push notification

    } else {

        // User hasn't opened it, this was a silent update

    }

}
