Activity Indicator while loading UIView

Question

I have a second view in my app that takes about 2-3 seconds to load. How can I create an activity indicator while the view loads?

I know I can do something like this:

UIActivityIndicatorView *activityView=[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

    activityView.center=self.view.center;

    [activityView startAnimating];

    [self.view addSubview:activityView];

But how do I tell my app to only load the activity view while switching to another view?

Answer 1

you can add this indicator in ViewWillAppear and every time that your view appears it must show indicator if it takes 2-3 seconds.

Answer 2

Use interface builder and create a new activity indicator on your SECOND VIEW.

    - (void) viewDidLoad
{

 [activityView startAnimating]; /// start animating

 [self performSelector:@selector(stopActivityLoad) withObject:self afterDelay:0.8]; /// stop animating after 0.8

}

- (void) stopActivityLoad
{

[activityView stopAnimating]; /// stop animating.

}
