How can i programatically stop animating UIActivityIndicatorView using Thread

Question

Hi i am beginner in objective C. I have an ActivityIndicator in my project.

UIActivityIndicatorView *loading = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[loading setCenter:CGPointMake(450,400)];
[loading setColor:[UIColor blackColor]];
[self.view addSubview:loading];

Is it possible to stopAnimating this activity indicator after some specific time using Thread?

Do you mean stopping UIActivityIndicatorView animating from another thread? — trungduc

Yes....I need to set up a thread that automatically stopAnimating my activity indicator after a specific time period. — SIDHARTH P U

I think you can use loading performSelector:@selector(stopAnimating) withObject:nil afterDelay:1];. — trungduc

could you please explain this code? What is the purpose of afterDelay:1 — SIDHARTH P U
– SIDHARTH P U, Commented Jul 10, 2018 at 9:10
It makes loading call method stopAnimating after 1 second. You can change 1 to another number for different delay. For more information, you can take a look at this developer.apple.com/documentation/objectivec/nsobject/… — trungduc

You can do it like

UIActivityIndicatorView *loading = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[loading setCenter:CGPointMake(450,400)];
[loading setColor:[UIColor blackColor]];
[self.view addSubview:loading];
// To stop after delay of 3 
[self performSelector:@selector(StopIndicator) withObject:nil afterDelay:3];

    -(void)StopIndicator
    {
    [loading stop];
    //[loading removeFromSuperview]; //uncomment if you want to remove it as well 

    }
