Fixed bug #1027 Vittorio Giovara 2010-07-17 19:21:36 PDT fix the double free error in SDL_uikitview the variable 'textfield' is initialialized and set to autorelease. however in the dealloc method a second [release] is sent. If the textfield has not been set to nil before (with a viewDidUnload for example) this can lead to awful hard-to-find crashes when the SDL code terminates. the error message is -[textfield release] message sent to deallocated instance 0x4e5fa90 the fix is simple, just release the object as soon as it is added to the subview, see attached patch
