@KDRocks. this Code is Running successfully for get the Name with complete Path.

-(NSString*) videoAssetURLToTempFile:(NSURL*)url
{
    NSString * surl = [url absoluteString];
    NSString * ext = [surl substringFromIndex:[surl rangeOfString:@"ext="].location + 4];
    NSTimeInterval ti = [[NSDate date]timeIntervalSinceReferenceDate];
    NSString * filename = [NSString stringWithFormat: @"%f.%@",ti,ext];
    NSString * tmpfile = [NSTemporaryDirectory() stringByAppendingPathComponent:filename];

    ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
    {
        ALAssetRepresentation * rep = [myasset defaultRepresentation];
        NSUInteger size = [rep size];
        const int bufferSize = 8192;
        NSLog(@"Writing to %@",tmpfile);
        FILE* f = fopen([tmpfile cStringUsingEncoding:1], "wb+");
        if (f == NULL) 
        {
            NSLog(@"Can not create tmp file.");
            return;
        }
        Byte * buffer = (Byte*)malloc(bufferSize);
        int read = 0, offset = 0, written = 0;
        NSError* err;

                      fromOffset:offset
                          length:bufferSize
                           error:&err];
            written = fwrite(buffer, sizeof(char), read, f);
            offset += read;
        } while (read != 0);
        }
        fclose(f);

    ALAssetsLibraryAccessFailureBlock failureblock  = ^(NSError *myerror)
