   it seems that it is trying to call an scheduled method, but the name is given name was incorrect.
   probably you missed the : in the name.

   check for:
   

   [self schedule:@selector(mySchedule)];  // WRONG

   Instead, it should be:
   

   [self schedule:@selector(mySchedule:)];  // OK. Notice the ':'

   @riq i double checked this before! I just cleanup the autorelease from actions, and now stop crash! Can be that @riq?

   @badawe: mmm... what did you do ? Did you remove the autorelease message from some actions ? autorelease should not crash any action. If you remove the autorelease and now it is not crashing, my guess is that you forgot to retain the action properly.

   Could you post some code ?

   @riq the problem still ocorrent, i don't know exactly what part of the code i must post to undestand what i'm doing wrong, i have one loading scene, and when i call the new scene, like score screen, i get this errors random, the the exaclty point of error is here:

   -(void) fire: (ccTime) dt
   {
   	if( elapsed == - 1)
   		elapsed = 0;
   	else
   		elapsed += dt;
   	if( elapsed >= interval ) {
   		impMethod(target, selector, elapsed);
   		elapsed = 0;
   	}
   }

   I Keep looking, probably is something i mess up. if if found something I post here!

   @riq, its the autorelease crashing my game, looke at this:

   -(void) showUpItens
   {
   
   	id showItem1 = [[Sequence actions: [ScaleTo actionWithDuration:0.2 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil] autorelease];
   	id showItem2 = [[Sequence actions: [ScaleTo actionWithDuration:0.4 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil] autorelease];
   	id showItem3 = [[Sequence actions: [ScaleTo actionWithDuration:0.2 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil] autorelease];
   	id showItem4 = [[Sequence actions: [ScaleTo actionWithDuration:0.4 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil] autorelease];
   	id showItem5 = [[Sequence actions: [ScaleTo actionWithDuration:0.5 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil] autorelease];
   	id showItem6 = [[Sequence actions: [ScaleTo actionWithDuration:0.6 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil] autorelease];
   	id showItem7 = [[Sequence actions: [ScaleTo actionWithDuration:0.7 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil] autorelease];
   
   	[as_height setVisible:true];
   	[as_boxes setVisible:true];
   	[as_trace setVisible:true];
   	[as_score setVisible:true];
   	[height_fontAtlas setVisible:true];
   	[boxes_fontAtlas setVisible:true];
   	[score_fontAtlas setVisible:true];	
   
   	[as_height runAction:showItem1];
   	[height_fontAtlas runAction:showItem2];
   	[as_boxes runAction:showItem3];
   	[boxes_fontAtlas runAction:showItem4];
   	[as_trace runAction:showItem5];
   	[as_score runAction:showItem6];
   	[score_fontAtlas runAction:showItem7];
   }

   If i using like that i get crash, just take of the autorelease and no errors:

   -(void) showUpItens
   {
   
   	id showItem1 = [Sequence actions: [ScaleTo actionWithDuration:0.2 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil];
   	id showItem2 = [Sequence actions: [ScaleTo actionWithDuration:0.4 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil];
   	id showItem3 = [Sequence actions: [ScaleTo actionWithDuration:0.2 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil];
   	id showItem4 = [Sequence actions: [ScaleTo actionWithDuration:0.4 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil];
   	id showItem5 = [Sequence actions: [ScaleTo actionWithDuration:0.5 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil];
   	id showItem6 = [Sequence actions: [ScaleTo actionWithDuration:0.6 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil];
   	id showItem7 = [Sequence actions: [ScaleTo actionWithDuration:0.7 scale:0.0],
   					[EaseElasticOut actionWithAction:[ScaleTo actionWithDuration:1.0 scale:1.0]],
   					nil];
   
   	[as_height setVisible:true];
   	[as_boxes setVisible:true];
   	[as_trace setVisible:true];
   	[as_score setVisible:true];
   	[height_fontAtlas setVisible:true];
   	[boxes_fontAtlas setVisible:true];
   	[score_fontAtlas setVisible:true];	
   
   	[as_height runAction:showItem1];
   	[height_fontAtlas runAction:showItem2];
   	[as_boxes runAction:showItem3];
   	[boxes_fontAtlas runAction:showItem4];
   	[as_trace runAction:showItem5];
   	[as_score runAction:showItem6];
   	[score_fontAtlas runAction:showItem7];
   }

   I know, you probably must reply things like that all the time, but if you can help me understand this, i ill be very happy:

   What i must release? If i have one Sprite* declared at my .h file, without @property/@@synthesize, i must release that? Even if i not retain it? And in some spots i read about set mySprite = nil; in the dealloc, everytime? or just when i retain?

   When i must call: [[TextureMgr sharedTextureMgr] removeAllTextures]; and [[TextureMgr sharedTextureMgr] removeUnusedTextures];? This clean my memory? If i call something like that propably in the Activity Monitor, i see the memory drops right?

   Sorry about that, but i almost done to release my app, and just want do things right!

   yes, the autorelease should not be there.
   [Sequence ...]; already returns an autoreleased object.

   I suggest reading this PDF:
   http://developer.apple.com/iphone/library/documentation/Cocoa/Conceptual/MemoryMgmt/MemoryMgmt.html

   It is a MUST read for every objective-c programmer.

   @riq thanks! Reading now!

   Just about the [[TextureMgr sharedTextureMgr] removeAllTextures]; and [[TextureMgr sharedTextureMgr] removeUnusedTextures];

   [[TextureMgr sharedTextureMgr] removeAllTextures]; use is whenever one scene call dealloc right?

   And
   [[TextureMgr sharedTextureMgr] removeUnusedTextures]; is in memory warning right?

   It is safe to use [[TextureMgr sharedTextureMgr] removeUnusedTextures]; in memory warnings.

   Regarding [[TextureMgr sharedTextureMgr] removeAllTextures];.... mmm... it depends on your game. If the next scene is going to use more or less the same textures, then I wouldn't remove them.
