Hello, I fixed my problem.
Problem is that Simulator is teminated abnormally.
After [cache addSpriteFramesWithFile:@"blob.plist"];

In my cast. format value is 2. and happend NSAssert
file : CCSpriteFrameCache.m
{
//..
if(format 1) {
NSAssert(NO,@”cocos2d: WARNING: format is
not supported for CCSpriteFrameCache
addSpriteFramesWithDictionary:texture:”);
return;
}
}

My new version: I write format value with 1.
and Test Code is operated normally.
Frankly, I don’t know actual cause.
In my opinion. ZWOPTEX output file(.plist) don’t mismatch Cocos2d version.
Thank you~
file : CCSpriteFrameCache.m
{

format = 1; //This is Hard Coding..

if(format 1) {
NSAssert(NO,@”cocos2d: WARNING: format is
not supported for CCSpriteFrameCache
addSpriteFramesWithDictionary:texture:”);
return;
}
}

Dear hhamm….
I met a problem. Below is debug message….
It is wrong point that
[cache addSpriteFramesWithFile:@"blob.plist"];
I don’t know what’s wrong.
My zwoptex version is newly demo version.
zwoptex option is
width : 512
height : 512
sort on : width

and then I export two files.
Export texture and Export coordinate..
Two files is good..

What’s Problem..?
Sincerely your help~

Are you sure resources are accessible and correct implemented? Seems that somehow [cache spriteFrameByName: fname] returns nil, which means by default that fname could not be resolved. This could be because something is missing or wrong. Like blob.plist does not point to the correct png file. Make sure you have a png file accessible which the plist file is pointing to. To see which png the plist is pointing to, look inside blob.plist. By default blob.plist will point to blob.png, so that should be your png file. Also you have to look which prior png files you used for zwopptex, these png files will be the accessors for the frames and are also stored inside the plist file. So “spriteWithSpriteFrameName” will look for them and load them as frame. You application seems to return nil here.

What should i do?

CCSprite will use the same file name except the extention will be PNG. Look into CCspriteFrameCache.m : method:”addSpriteFramesWithFile” for further details. So if your plist file is “blob.plist” cocos2d will automatically associate “blob.png” to be load as atlas sprite, which will be loaded into the frame cache the same time when plist file is specified. If you want to use a specifc texture file you can call “addSpriteFrameWithFile:@”blob.plist” texture:[[CCTextureCache sharedTextureCache] addImage:@”myblob.png”];

Since Version 0.9 they changed the access to the Frame-Cache Instance to [CCSprite spriteWithSpriteFrameName:frameName]
So change the line :
CCSprite * blob = [cache createSpriteWithFrameName:@"blob_idle_01.png"];

CCSprite * blob = [CCSprite spriteWithSpriteFrameName:@"blob_idle_01.png"];
