how can I display UIImage from image url

Question

The code below works fine if I give statically but

imgDescView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:
[NSURL URLWithString:[NSString stringWithFormat:@"http://4cing.com/mobile_app/uploads/pageicon/6.jpg"]]]];

Same code - I am passing the image url name dynamically it's not working

imgDescView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:
[NSURL URLWithString:[NSString stringWithFormat:@"%@",[imagename objectAtIndex:0]]]];

print [imagename objectAtIndex:0] and check its equal to http://4cing.com/mobile_app/uploads/pageicon/6.jpg — Paresh Navadiya, Mar 20 '13 at 09:11

URL is not created. So u need to add http:// before [imagename objectAtIndex:0] and it should work!!! — Paresh Navadiya, Mar 20 '13 at 09:18
@RayofHope how would it compile if Closing Bracket was Missing at end. — Paresh Navadiya, Mar 20 '13 at 09:20
Check the array whether it is storing images or not..bcoz what i see u r unable to access it from array.. — Kundan, Mar 20 '13 at 09:34

NSMutableArray *imagename = [[NSMutableArray alloc] initWithObjects:@"http://4cing.com/mobile_app/uploads/pageicon/6.jpg", nil];
UIImageView *imgDescView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 200, 200)];

imgDescView.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:
                                            [NSURL URLWithString:[NSString stringWithFormat:@"%@",[imagename objectAtIndex:0]]]]];

it is working ... i think u r not creating array properly.

You need to verify the NSArray contents. Log out the objects of the array:

NSLog(@"imagename = %@",[imagename description]);

Also, a side-note - might want to think about loading that image dynamically. I wrote a class that makes this pretty painless:

The answer is geared toward using in TableViews (where lag would really hurt performance), but you can (and I do) use this for any web image loading. This keeps the UI fluid and is very fast.

[NSURL URLWithString:[[NSString stringWithFormat:@"%@",[imagename objectAtIndex:0]] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]
