IBM Worklight 6.0-在iOS模拟器中进行预览时，如何避免推送通知错误？

Question

I am using IBM Worklight 6.0.0 and testing on iOS 7 Simulator.

I have the following JavaScript error. It appears everytime I login.

Error while trying to retrieve device token from the mobile operating system.
  (anonymous function)           cordova.js:5312
  __log                        worklight.js:1292
  (anonymous function)         worklight.js:1377
  __updateTokenCallbackError    wlgap.ios.js:403

On the client side, my code is:

if (WL.Client.Push){

    WL.Client.Push.onReadyToSubscribe = function(){
        WL.Logger.debug("onReadyToSubscribe");

        if (isPushSubscribed() == false) {
            doSubscribe();
        }
    };  
}
if (WL.Client.Push){
        WL.Client.Push.registerEventSourceCallback(
                "myPush", 
                "PushAdapter", 
                "PushEventSource", 
                pushNotificationReceived);
}

How can I avoid this error?

Answer 1

Use Cordova's device.name API method. You can also use WL.Client.getEnvironment to do the same, but for when previewing in the Worklight Console.

If you get "iPhone Simulator" (or "Preview" in the case Worklight Console), don't enter into those code blocks... do something else instead. Otherwise, continue into them.
