Crashing on simulator target 5.1 with MapKit

Get the following error whenever initializing a MKMapView with showsUserLocation = true on simulator targeting 5.1.

'uri.rb:4:in 'decode_www_form:': undefined method 'split' for nil:NilClass

I guess Google Maps uses that method to resolve user location. It works fine on 6.0 since MKMapView uses Apple Maps and does not call the above method anymore.

Question are

  1. Should fix it by checking null string?
  2. Or, should not monkey patch URI class?

Wow, that sucks! I'd rather not mutilate the class names (URI -> WSURI) to assuage the Objective-C runtime, but I don't see any other choice.

If you hack up the gem to do that, does it work?

I modified the method to check empty string and it works, though I don't think it is the solution.

I prefer separate class or utility methods rather than monkey patching core ruby/objc classes unless RubyMotion has a way to conditionally compile source code based on environment.

Finally got a chance to sit down with this one. Looks like Google Maps in 5.1 sends a Content-Type of application/x-www-form-urlencoded with a HTTP body that is decidedly not URL-encoded. The URI class chokes on this because it's expecting a String.

This issue is fixed in 0.3.7 by not handling requests at all in dev mode. The mismatched Content-Type/body handling is fixed in master.

Thank you for bringing this to my attention.
