    <p>I am using a <code>UIActivityIndicatorView</code> as an <code>IBOutlet</code>. I am trying to control it using <code>[activityView startAnimating]</code> and <code>[activityView stopAnimating]</code>.</p> <p>I have enabled 'Hides when stopped' and 'Animating' behaviors in XIB file.</p> <p>I want to start animate the spinner for several user actions inside the controller. But after the first <code>[activityView stopAnimating]</code> call it does not response to <code>[activityView startAnimating]</code> call again. </p> <p>That is mean the spinner is disappeared after the first <code>[activityView stopAnimating]</code> call.</p> <p>I tried <code>activeView.hidden = NO;</code> before the next <code>[activityView startAnimating]</code> call. But it does not work. </p> <p>Any idea about this issue?</p> <p><strong>Edited</strong></p> <p>After my controller loaded I do follow thing,</p> <pre><code>do { [self.activityIndicator startAnimating]; [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [webServiceCallOperation getResults]; [self.activityIndicator stopAnimating]; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; } while (![webServiceCallOperation isValideResponse] || [webServiceCallOperation isServerError]); </code></pre> <p>In the same controller I have a IBAction for a button click. </p> <pre><code>- (IBAction)tappedSearchButton:(id)sender { [self.activityIndicator startAnimating]; [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [self tappedSearchButtonAction]; [self.activityIndicator stopAnimating]; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; } </code></pre> <p>I noticed that the spinner not begin to animate just after the <code>[self.activityIndicator startAnimating];</code> call. Using <code>[self tappedSearchButtonAction];</code> I call to a web service and go to the search results view. The spinner begin to animate just before change the view. That's why I did not see it. But I suppose to animate it before web service call and should animate it while my web service call.</p> <p>Same behavior of the network activity indicator. </p>

    1. COAre you sure it is not released? Also, you start the second time on the main thread only, right?

    2. COProvide some code. It's difficult to understand what is going on. Check if the indicator stays under your curent displayed view.

    3. COSure. I do not release the spinner object. And also I noticed the problem. It's animating. But it does not animating just after the [activityView startAnimating] call. I could not find when it starts to animate. I edited my problem by adding my codes.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
