    text
    copied!<p>I want to animate images on multiple UIImageViews.Image is coming from server side with Url so i request url and convert it in to image and i give animation to uiimageview i.e. crossdissolve , one issue is occured image reference is changing in UIImageView means first time it's displaying different images and when i scroll then other image display on same UIImageView.This problem will occur only for the first time because i maintain imagecache.Any idea about this bahavious ?. Below is code that i used.</p> <pre><code>-(void)requestForImage:(NSString*)strURL{ NSOperationQueue *queue = [[NSOperationQueue alloc] init]; NSURLRequest *request; NSString * newImageURL = [strURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; request = [NSURLRequest requestWithURL:[NSURL URLWithString:newImageURL]]; [NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) { UIImage *image = [UIImage imageWithData:data]; if ([data length] &gt; 0 &amp;&amp; error == nil &amp;&amp; image) //If success { //receive data [[myImage sharedMyclass] setImage:image withKey:strURL]; dispatch_queue_t queue_ = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul); dispatch_async(queue_, ^{ UIImage *image = [[myImage sharedMyclass] imageForURL:strURL]; //That return image from particular path [self performSelectorOnMainThread:@selector(receivedImage:) withObject:image waitUntilDone:NO]; [data writeToFile:[[NSUserDefaults standardUserDefaults] valueForKey:strURL] atomically:YES]; dispatch_sync(dispatch_get_main_queue(), ^{ [UIView transitionWithView:self duration:2.0 options: UIViewAnimationOptionTransitionCrossDissolve|UIViewAnimationOptionAllowUserInteraction animations:^{ self.image = image; } completion:NULL]; self.contentMode = UIViewContentModeScaleAspectFit; }); }); } }]; } </code></pre>
