Question

NSURL *url = [NSURL URLWithString: 
              pictureUrl];
UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL:url]];  
NSLog(@"image width:%@",image.size.width);

I am getting null from this log? The image is valid and displaying correctly?.
This is in a table cell

Answer 1

Try this:

NSLog(@"image width:%f",image.size.width);

Besides that, I hope you are calling this on a background thread (not within cellForRow), otherwise loading your cells will be very slow and screw up user interaction.
