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
