application crashes at spriteFrameByName in NSMutableArray

Question

[action_array addObject:[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:[NSString stringWithFormat:@"baloon-bl_%d",i]]; 

我该如何解决

Answer 1

I believe there are brackets missing. Try:

[action_array addObject:[[CCSpriteFrameCache sharedSpriteFrameCache]spriteFrameByName:[NSString stringWithFormat:@"baloon-bl_%d",i]]];
