Hi all!
I'm implementing a singleton class that controls access to a SPTextureAtlas, but when i run the game on a real Device (and only on real device) I get the following error:
NOTE: when I just call "atlasGeneral" instead of "atlasGeneral2" works correctly on simulator and device (I've imported the necessary files).
Seems that the application can not find the file when running on the device

Here's my code:
Atlas.h
#import <Foundation/Foundation.h> @interface Atlas : NSObject { } + (SPTextureAtlas *)atlasGeneral; + (SPTextureAtlas *)atlasGeneral2; @end
on Atlas.m
#import "Atlas.h" /* Singleton */ @implementation Atlas + (SPTextureAtlas *)atlasGeneral { static SPTextureAtlas *atlasCompartido; @synchronized(self){ if (!atlasCompartido) { atlasCompartido = [SPTextureAtlas atlasWithContentsOfFile:@"atlas_general.xml"]; //Lazy initialization [atlasCompartido retain]; } } return atlasCompartido; } + (SPTextureAtlas *)atlasGeneral2 { static SPTextureAtlas *atlasCompartido_2; @synchronized(self){ if (!atlasCompartido_2) { atlasCompartido_2 = [SPTextureAtlas atlasWithContentsOfFile:@"atlas_general-2.xml"]; //Lazy initialization [atlasCompartido_2 retain]; } } return atlasCompartido_2; } - (void)dealloc { [super dealloc]; } @end
On my Game.m I instantiate it:
SPImage *img = [[Atlas atlasGeneral2] textureByName:@"texture_0"]; [container addChild:img];
Any Idea?
Thanks guys!
Great Framework, but i'm still learning 
Ok, Solved! My XCode had gone mad...
