POHow to solve delay of progressView's movement animation
text
Body
copied!<p>Currently, I'm downloading data from a web server by calling a method <code>fetchProducts</code>. This is done in another separate thread. As I successfully download fifty items inside the method stated above, I <code>post</code> a notification to the <code>[NSNotification defaultCenter]</code> through the method call <code>postNotificationName: object:</code> which is being listened to by the <code>Observer</code>. Take note that this <code>Observer</code> is another <code>ViewController</code> with the selector <code>updateProductsBeingDownloadedCount:</code>. Now as the <code>Observer</code> gets the notification, I set the property of my <code>progressView</code> and a label that tells the progress. Below is the code I do this change in UI.</p> <pre><code>dispatch_async(dispatch_get_main_queue(), ^{ if ([notif.name isEqualToString:@"DownloadingProducts"]) { [self.progressBar setProgress:self.progress animated:YES]; NSLog(@"SetupStore: progress bar value is %.0f", self.progressBar.progress); self.progressLabel.text = [NSString stringWithFormat:@"Downloading %.0f%% done...", self.progress * 100]; NSLog(@"SetupStore: progress label value is %@", self.progressLabel.text); [self.view reloadInputViews]; } }); </code></pre> <p>The idea is to move the <code>progressView</code> simultaneously as more items were being downloaded until it is finished. In my case, the <code>progressView</code>'s animation will just start right after the items were already downloaded, hence a delay. Kindly enlighten me on this. </p>
