- (NSString *)getTimeStringWithSeconds:(NSInteger)seconds {
    NSInteger hour = seconds / 3600, min = (seconds % 3600) / 60, sec = seconds % 60;
    NSString *timeString = seconds > 3600 ? [NSString stringWithFormat:@"%02ld:%02ld:%02ld", (long)hour, (long)min, (long)sec] : [NSString stringWithFormat:@"%02ld:%02ld", (long)min, (long)sec];
    NSLog(@"timeString:%@",timeString);
