@iSwap - I know that why your code is not working.

i think you put an url as a string instead of url. as above code ----

imageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:aURL]];

there is aURL that should be a url not a string, and u wrote it as a string like

imageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:@"http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World"]];

you have been forget to convert this string into an url.

the right method will be like this-

imageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World"]]];

i hope you got it, and one more thing there is no difference between "willcodejavaforfood" and "CodeBrickie" code. just way of writing is little differ.

This would block, use NSURLConnection for non-blocking download

NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Hello|World"]];

UIImage *downloadedImage = [UIImage imageWithData:imageData];

myImageView.image = downloadedImage;

Try imageView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:aURL]]
