Answer 1

ALAssetsLibrary *al = [[ALAssetsLibrary alloc] init]; 


[al enumerateGroupsWithTypes:ALAssetsGroupAll 

    usingBlock:^(ALAssetsGroup *group, BOOL *stop) 
    { 
     [group enumerateAssetsUsingBlock:^(ALAsset *asset, NSUInteger index, BOOL *stop) 
     { 
      if (asset) 
      {     
       .. do something with the asset 
      } 
     } 
     ]; 
    } 

    failureBlock:^(NSError *error) 
    { 
     // User did not allow access to library 
     .. handle error 
    } 
];
