how to allocate NSTimer property from another class in my class - objective-c

Question

I have two class. I have one property NSTimer in my first class like this:
#interface KKProgressTimer : UIView
#property(nonatomic,retain) NSTimer *TimeCount;
#end
I could create two object from KKProgressTimer class and add in my second class.
in my second class I want to allocate NSTimer property to every object KKProgressTimer class.but I can't please guide me!!!
//this loop check and get two object KKProgressTimer class
for (UIView *subview in self.view.subviews) {
if ([subview isKindOfClass:[KKProgressTimer class]]) {
KKProgressTimer *Progress = (KKProgressTimer*)subview;
//now I want to allocate NSTimer property this here and define scheduledTimerWithTimeInterval for it
//timing = [[NSTimer alloc]init];
//timing = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:#selector(CountDown:) userInfo:timing repeats:YES];
}
}

Answer 1

I would probably create a method inside KKProgressTimer to start up its own timer and handle its own callbacks but if you want to do it from outside, try:
Progress.TimeCount = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:#selector(CountDown:) userInfo:timing repeats:YES];
Note, however that this means the object that contains the loop is going to get all the timer callbacks for both subviews.

My friend maybe you forget set method for TimeCount.
write this code in second class:
Progress.TimeCount = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:#selector(CountDown:) userInfo:timing repeats:YES];
and write this code in .m file KKProgressTimer class
- (void)setTimeCount:(NSTimer *)TimeCount {
if (TimeCount) {
TimeCount = nil;
}
}
