Answer 1

The URL you give isn’t an image so it won’t work.

More importantly, while it looks OK, it’s absolutely not recommended to do it like this.

The call to dataWithContentsOfURL: is blocking the main thread during the download, making the app unresponsive.

Take a look at some open-source projects as mentioned by Antaresm.
You may also want to look at AFNetworking, put it in your project and then, all you have to write is

[UV setImageWithURL:url];
