Question

I am developing a 2D iPhone game by using cocos2d. I need a countdown timer. How can I create a count down timer in cocos2d?

Answer 1

Not enough rep to upvote Tom, but he’s absolutely right. Within the context of this question, NSTimer is the WRONG solution. The Cocos2d framework provides a scheduler that integrates with other game features like Pause/Resume (and most likely uses NSTimer under the hood).

Example from the above link:

-(id) init {     if( ! [super init] )         return nil;      // schedule timer     [self schedule: @selector(tick:)];     [self schedule: @selector(tick2:) interval:0.5];      return self; }  -(void) tick: (CCTime) dt {     // bla bla bla }  -(void) tick2: (CCTime) dt {     // bla bla bla }
