Timer Help

[doopster]

Hi. Ive been making a game and for some reason instead of this number counting down by 1 its been counting down by 4. Here is my code below:

- (IBAction)count:(id)sender {
    myTimer = 60;
    myTicker = [NSTimer scheduledTimerWithTimeInterval: 0.5 target: self selector: @selector(showActivity) userInfo: nil repeats: YES];
}
- (void)showActivity {
    myTimer = myTimer-1;
    text.text=[NSString stringWithFormat:@"%i", myTimer];
}

Please Help

Why are you calling showActivity every 0.5 seconds? If it is a timer, wouldn't you want it calling every second? I would set it up personally as:

-(void)someMethod {

myTimer = 60;
myTicker = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(showActivity) userInfo:nil repeats:YES];

}

-(void)showActivity {

myTimer = myTimer - 1;
textView.text = [NSString stringWithFormat:@"%d",myTimer];

}

Declare myTicker as an NSTimer and myTimer as an integer.

int myTimer;
NSTimer *myTicker;

I tried that code and its still Counts down by 4 (e.g 60, 56, 52 )

The most common cause for a "timer value" to count by 4's is that it's incorrectly declared as "int *", rather than just "int". Double-check the declaration in your class interface.

Thank you, that worked! I had "int *myTimer" instead of "int myTimer"
THANKYOU!!!!

For the record, this is what Speed suggested two posts before mine, and you said that you tried it and it didn't work... :/

Woops I didn't notice that there was no * on Speeds post. I thought that it had it. There for My Bad. I guess that speeds post did solve the problem. And that you just kind of showed me what I missed.

So thankyou to you both!
