PFPush handlePush crash: NSCFDictionary length

Question

I'm getting a crash when the app is open and it receives a push notification.

[PFPush handlePush:userInfo];

the JSON is a simple alert: title, body and one custom field that's a hex number.

userInfo:

{
    aps =     {
        alert =         {
            body = "Test Body";
            title = "Test Title";
        };
    };
    url = "miner://item/5528c5aeaacfce1fd2d527dd";
}

Just checked your sample code and you're right: this kind of string messages are crashing while handled by PFPush handlePush:

The reason why this is happening: The Parse supports iOS and Android PushNotification services at the same time, which means it cannot use any service-specific format in the general JSON string.

iOS uses these kind of formats:

{
    "aps" : {
        "alert" : {
            "title" : "Game Request",
            "body" : "Bob wants to play poker",
            "action-loc-key" : "PLAY"
        },
        "badge" : 5,
    },
    "acme1" : "bar",
    "acme2" : [ "bang",  "whiz" ]
}

And Android

"data": {
            "title": "Push Title",
            "message": "Push message for Android",
            "customData": "Custom data for Android"
        }

In Parse, you need to use a different format type like

{
  "alert": "Tune in for the World Series, tonight at 8pm EDT",
  "sound": "chime",
  "title": "Baseball News"
}

In an iOS app, this will be the userInfo object from the JSON string above:

{
    aps =     {
        alert = "Tune in for the World Series, tonight at 8pm EDT";
        sound = chime;
    };
    title = "Baseball News";
}

In this userInfo, the alert is an NSString instead of an NSDictionary. When the Parse SDK tries to process that, it sends a length message to the instance - which causes the crash.
