-----------------------------------

             Summary: Change custom URL scheme handling in iOS
                 Key: CB-853
                 URL: https://issues.apache.org/jira/browse/CB-853
             Project: Apache Cordova
          Issue Type: Bug
          Components: iOS
            Reporter: Shazron Abdullah
            Assignee: Shazron Abdullah
             Fix For: 2.0.0


Don't know about the other platforms, but there are two ways it is handled in iOS right now,
we need to consolidate.

Summary:
The url scheme passed to the app is a form of inter-process communication, kinda like how
we do gap:// urls, but this is up to the app developer on how they marshal/unmarshal the url
into something they can use.

Right now in iOS, it is a bit confusing - there are two ways that the URL is handled and passed
off to the UIWebView.

 1. On *first* app startup, the URL sent is passed off to the UIWebView by setting a global
variable - *window.invokeString*. The URL is passed off untouched (see: https://github.com/apache/incubator-cordova-ios/blob/master/Cordova-based%20Application/Classes/AppDelegate.m#L67)

 2. On *subsequent* launches, i.e. resume from background (multi-tasking), the handleOpenURL
function is called instead, and this in turn calls the global JavaScript function in the UIWebView
*window.handleOpenURL()* and this is passed the URL, untouched (see: https://github.com/apache/incubator-cordova-ios/blob/master/Cordova-based%20Application/Classes/AppDelegate.m#L126)
