NSData *assetData = [NSData dataWithContentsOfURL:asset.defaultRepresentation.url]; // img is my imageview img.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:asset.defaultRepresentation.url]]; //NSLog(@"Asset Data = %@",assetData);when i check the log i get (null)can you help me figure out why i'm not able to load image with the given URL. some people say this feature was available in IOS 4.0 and now in 5.0 not possible. great it works fine..

-    void (^assetEnumerator)(struct ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *result, NSUInteger index, BOOL *stop) {};+    void (^assetEnumerator)(ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *result, NSUInteger index, BOOL *stop) {};

If i keep the struct keyword i get an error.

Thank you very much for this tutorial.  Just wanted to point out that we had  some major problems getting Xcode 4.0.2 to accept the block syntax you provided.  Finally managed to hunt down some other examples and got the following syntax to work:ALAssetsGroupEnumerationResultsBlock assetEnumerator = ^(ALAsset *result, NSUInteger index, BOOL *stop) {                  }; Hi Colin.
