Answer 1

Get Url by this,

NSURL *url= (NSURL*) [[asset valueForProperty:ALAssetPropertyURLs] valueForKey:[[[asset valueForProperty:ALAssetPropertyURLs] allKeys] objectAtIndex:0]];

And get image from url like below.

ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
{
    ALAssetRepresentation *rep = [myasset defaultRepresentation];
    @autoreleasepool {
        CGImageRef iref = [rep fullScreenImage];
        if (iref) {
            UIImage *image = [UIImage imageWithCGImage:iref];
            self.loadedImage = image;
            dispatch_async(dispatch_get_main_queue(), ^{
                //UIMethod trigger...
            });
            iref = nil;
        }
    } 
};

ALAssetsLibraryAccessFailureBlock failureblock  = ^(NSError *myerror)
{
    NSLog(@"Can't get image - %@",[myerror localizedDescription]);
};

ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init];
[assetslibrary assetForURL:yourUrl
               resultBlock:resultblock
              failureBlock:failureblock];
