Fire countdown from subclass - ios

Question

I have those methods to create a simple countdown in my ViewController.m:
- (void)viewDidLoad {
[super viewDidLoad];
secondsLeft = 10;
}
- (void)updateCounter:(NSTimer *)theTimer {
if(secondsLeft > 0 ){
secondsLeft -- ;
seconds = (secondsLeft %3600) % 60;
myCounterLabel.text = [NSString stringWithFormat:#"%02d", seconds];
}
else{
secondsLeft = 10;
}
}
-(void)countdownTimer{
secondsLeft = seconds = 0;
timer = [NSTimer scheduledTimerWithTimeInterval:1.0f target:self selector:#selector(updateCounter:) userInfo:nil repeats:YES];
}
From where I call the method in the subClass :
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
[self.vc countdownTimer];
}
So I have a ViewController with a UIView inside. This UIView has a custom class. I want to call from this custom Class a method which is in the ViewController. I achieved to call it but the myCounterLabel.text is logged as (null)... Whereas I call the method from the ViewController itself the myCounterLabel.text is correctly logged with the left seconds. Thanks for your help!

Answer 1

countdownTimer method is in view controller.m file and you calling it from other view controller by making object of ViewController controller but do you notice one thing? When you call countdownTimer method then everytime secondsLeft will be 0 and it set to 10 so whenever you call countdown timer method secondsLeft will be reset.
So timer will not start
