copied!<p>I just wrote a small application that read from a site feed and display in UITableViewCell. I am using custom view cell and my UITableView is screwed in scrolling like it is not very smooth in scrolling upside down. Any idea? Here's the code for my UITableViewCell,</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CustomCell"; CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { // cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:nil options:nil]; for(id currentObject in topLevelObjects) { if([currentObject isKindOfClass:[UITableViewCell class]]) { cell = (CustomCell *) currentObject; break; } } } //MiceAppDelegate *AppDelegate = (MiceAppDelegate *)[[UIApplication sharedApplication] delegate]; if(dataArray != nil) { // //NSArray *promoArray = (NSArray *) promotions; NSDictionary *datadict = [self.dataArray objectAtIndex:indexPath.row]; NSString *url = [datadict objectForKey:@"imageUrl"]; NSString *title = [datadict objectForKey:@"title"]; NSString *description = [datadict objectForKey:@"description"]; NSString *newAddressPartOfURL = [url stringByReplacingOccurrencesOfString:@" " withString:@"+"]; //NSLog([url stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]); NSURLResponse *urlResponse; NSData *data = [NSURLConnection sendSynchronousRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newAddressPartOfURL]] returningResponse:&urlResponse error:nil]; // Configure the cell. UIImage *urlImage = [[UIImage alloc] initWithData:data]; // NSLog(@"%i",[imageView.image topCapHeight]); cell.title.text = title; cell.description.text = description; cell.image.image = urlImage; [urlImage release]; } return cell; } </code></pre>
