UIActivityIndicatorView to send an action
Got an iPhone app enhancement request today to be able to tap the spinning activity indicator (UIActivityIndicatorView) to pop up some info on the status of the busy activity. UIActivityIndicatorView isn't like a UIButton which has sent actions, so is there a way to do this? -Carl ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: What's the right way to use UIActivityIndicatorView? After it's stopped
You can stack views and controls however you like. I do it all the time. You need to pay attention to the list of views, not just the visuals in iB. Just use an outlet or binding to hide the ones you don¹t want showing. Set the activity indicator to hide when not active. When you stop animation, unhide the other control.

UIActivityIndicatorView stops animating when table view cell moves
I have a UIActivityIndicatorView in a UITableViewCell that's set up in a dynamic-content cell prototype in a storyboard. It works fine, in that it's animating when displayed, unless the cell is removed and re-inserted. Then it stops animating (still shows). I never actually tell it to stop.

That won't work. Views are only redrawn once your method returns. So while
your activity indicator is shown and hidden, nobody will ever see it. If you do
activities that take a long time, you'd better split them up into smaller
NSOperations which let the main thread redraw the UI in between each operation.
Or if you have to, use a separate thread, but that's hard to get right, and
easy to get wrong in a way that causes random hard-to-find crashes.

UIActivityIndicatorView
Hi all.
I use an activity indicator in order to show, in my UIViewController, a "work
in progress" activity.
here my code
- (void)myMethod
{
[[self activityElab] setHidden:NO];
[[self activityElab] startAnimating];
// here I call a very CPU-intensive method.
[[self activityElab] setHidden:YES];
[[self activityElab] stopAnimating];
}
My problem is that nothing appear (activity indicator) when myMethod is called.
Now if I remove (comment) the call to my "intensive activity" method all is
working fine.
Any idea? I've tested this code both on the simulator and on a device (iPad)
with iOS 5.0 and iOS 6.0
My environment is Xcode 4.5.2 on OS X 10.8.2.
Thanks in advance.
Luca.

Use delayed performance. Here's sample code from one of my own apps:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath
*)indexPath {
[act startAnimating];
// jump out using delayed performance, to give us a chance to start
animating the UIActivityIndicatorView
[self performSelector:@selector(showItemsForRow:) withObject:indexPath
afterDelay:0.1];
}
And then showItemsForRow inits the view controller and loads its view in the
usual way. m.
