Cordova app for iOS with Plugins - ios

Question

I am trying to create a cordova app for iOS. The same app we are using for android as well. I just tried to add the iOS plugin and launch the app. I have added below code in CDVDevice.h.
http://developmobilesoftware.blogspot.in/2013/12/the-unique-identifier-in-ios-app-udid.html
I am getting exception and my trace is as under :
+[CDVDevice uniqueIDForDevice] : unrecognized selector sent to class 0xf30c4
** WebKit discarded an uncaught exception in the webView: decidePolicyForNavigationAction:request:frame:decisionListener:delegate"<NSInvalidArgumentException> +[CDVDevice uniqueIDForDevice]: unrecognized selector sent to class 0xf30c4
Please help I am new to iOS programming.
Thank You!

First of all, editing CDVDevice isn't a good idea
But you can do two different things to fix your code:
change [devProps setObject:[[self class] uniqueIDForDevice] forKey:#"uniqueid"];
to [devProps setObject:[self uniqueIDForDevice] forKey:#"uniqueid"];
or change -(NSString*)uniqueIDForDevice
to +(NSString*)uniqueIDForDevice
Explanation, class methods start with +, instance methods start with -, you have declared an instance method but you call it like a class method, so you can change the class method to instance method changing the - to + or keep it as instance method and call it as an instance method just with self instead of [self class]
Anyway, as I said before, instead of editting the device plugin, you can use my identifier for vendor plugin

window.IDFVPlugin.getIdentifier(function(identifier){ alert(identifier); },function(error){ alert(error); });
