        Hi all,

        I'm having trouble in trying to access the content of a sprite kit particle file in a way that conforms with the recent deprecation of several functions in NSKeyedArchiver.

        Briefly, my project contains a file named "ParticleSmoke.sks", which I used to access easily with the following lines of code:


             NSString *smokePath = [[NSBundle mainBundle] pathForResource:@"ParticleSmoke" ofType:@"sks"];

             SKEmitterNode* smoke = [NSKeyedUnarchiver unarchiveObjectWithFile:smokePath];


        now that the unarchiving function has been deprecated, I fail to use the (poorly documented)  unarchivedObjectOfClass function. Especially, the code below returns nil.


             NSString *smokePath = [[NSBundle mainBundle] pathForResource:@"ParticleSmoke" ofType:@"sks"];

             NSData* smokeData = [NSData dataWithContentsOfFile:smokePath];

             NSError* error=nil;

             Class cls = [SKEmitterNode class];

             SKEmitterNode* smoke = (SKEmitterNode*)[NSKeyedUnarchiver unarchivedObjectOfClass:cls fromData:smokeData error:&error];


        Unexpectedly, the content of "error" (code 4864) was

        @"NSDebugDescription" : @"value for key 'NS.objects' was of unexpected class 'NSColor'. Allowed classes are '{(\n    SKKeyframeSequence,\n    NSArray,\n    NSNumber,\n    NSMutableArray\n)}'."


        Has anyone an idea to fix this issue?

        Thanks for your help....
