ImageView loads local image but not from URL

Question

I am having trouble getting an image to load from a URL. I have CollectionViewCell subclass with an image view setup like this:

@property (strong, nonatomic) IBOutlet UIImageView *albumCover;

I cannot get it to load images from a URL. Here is the code im using:

NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString: song.albumURL]];
cell.albumCover = [[UIImageView alloc] initWithImage:[UIImage imageWithData: imageData]];

Meanwhile, this works:

cell.albumCover.image = [UIImage imageNamed:@"lock.png"];

I know the URL connection is getting the proper image back because I am monitoring it with Fiddler. Why isn't the image showing up then?

I was allocating the UIImageView object again instead of just initializing it with the image. The correct code is:

NSData * imageData = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString: song.albumURL]];
[cell.albumCover initWithImage:[UIImage imageWithData: imageData]];

SDImageview also does so much more awesome stuff, like build it animated gifs! – David Wong Sep 03 '13 at 02:59

You should use fileURLWithPath: instead of the URLWithString:.

URLWithString: is for WWW URL.

And an example:

NSString *rootPath = [[NSBundle mainBundle] resourcePath];
NSString *filePath = [rootPath stringByAppendingPathComponent:@"example.mov"];
NSURL *fileURL = [NSURL fileURLWithPath:filePath isDirectory:NO];
yourMoviePlayer = [[MPMoviePlayerController alloc] initWithContentURL: fileURL];
