Question

I am trying to loading images in tableViewCell asynchronously.
When I move the table up and down then images appear otherwise not.

AsyncImageView contains NSUrlConnection. It doesn’t go inside the delegate “connectionDidFinishLoading”. but when I move the table up or down then it goes inside this delegate function

Below is the code

        CGRect frame;
        frame.size.width=115; frame.size.height=100;
        frame.origin.x=0; frame.origin.y=0;
        AsyncImageView* asyncImage = [[[AsyncImageView alloc]
                                       initWithFrame:frame] autorelease];
        loadingTable=[[UIActivityIndicatorView alloc] initWithFrame:frame];
        [cell.contentView addSubview:loadingTable];
        [loadingTable startAnimating];
        asyncImage.tag = 999;
        NSURL* url = [NSURL URLWithString:[[videoCollection objectAtIndex:indexPath.row] videoImageUrl] ];
        [asyncImage loadImageFromURL:url activity:loadingTable];
        [cell.contentView addSubview:asyncImage];

First load all images and add them some data structure like array and after that show it to the table. Don’t overlap your UI with network calls.
