    <p>the best way is to add the activityIndicator in all "setImage" functions in UIImageView+WebCache.m, after that you remove it in "webImageManager:r didFinishWithImage:" , i test it in device and it work smoothly, her's an example : </p> <pre><code> - (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder { UIActivityIndicatorView *activity = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:(UIActivityIndicatorViewStyleWhiteLarge)]; [activity startAnimating]; [activity setCenter:self.center]; [self addSubview:activity]; [activity release]; SDWebImageManager *manager = [SDWebImageManager sharedManager]; UIImage *cachedImage = [manager imageWithURL:url]; if (cachedImage) { // the image is cached -&gt; remove activityIndicator from view for (UIView *v in [self subviews]) { if ([v isKindOfClass:[UIActivityIndicatorView class]]) { [activity removeFromSuperview]; } } } [self setImageWithURL:url placeholderImage:placeholder options:0]; } </code></pre> <p>and you remove it with a fade animation ;) :</p> <pre><code> - (void)webImageManager:(SDWebImageManager *)imageManager didFinishWithImage:(UIImage *)image { for (UIView *v in [self subviews]) { if ([v isKindOfClass:[UIActivityIndicatorView class]]) { // NSLog(@"-didFinishWithImage-"); [((UIActivityIndicatorView*)v) stopAnimating]; [v removeFromSuperview]; } } [UIView beginAnimations:@"fadeAnimation" context:NULL]; [UIView setAnimationDuration:0.9]; self.alpha = 0; self.image = image; self.alpha=1; //[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self cache:YES]; [UIView commitAnimations]; } </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
