Question

How can I lazy load images in a UITableView cell, with a fade-in effect when the image is loaded?

Answer 1

You are reffering to Asynchronous images. There is a great article available at: http://www.markj.net/iphone-asynchronous-table-image/

Within the connectionDidFInishLoading just put the later after this

UIImageView* imageView = [[[UIImageView alloc] initWithImage:[UIImage imageWithData:data]] autorelease];
//Paste below code here

to fade it in:

//Paste following here
imageView.alpha = 0.0f;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5f];

imageView.alpha = 1.0f;

[UIView commitAnimations];
