Iphone stop assetEnumerator

void (^assetEnumerator)(struct ALAsset *, NSUInteger, BOOL *) = ^(ALAsset *result, NSUInteger i开发者_Python百科ndex, BOOL *stop) {

How can I stop the assetEnumerator run loop?

Thanks.

Pretty much what the documentation says:

in the block do:

*stop = YES;

Then after you current "iteration", it'll cease to enumerate the assets.
