本机时间转换成秒

    //时间

      NSDateFormatter *formatter = [[NSDateFormatter alloc]init];

    [formatter setDateFormat:@"HH:mm:ss"];

    NSString *strDate = [formatter stringFromDate:[NSDate date]];

    //本机转换成秒

    NSArray *dateArr = [strDate componentsSeparatedByString:@":"];

    

    int s1 = [dateArr[0] intValue]; //时

    int s2 = [dateArr[1] intValue]; //分

    int s3 = [dateArr[2] intValue]; //秒

    NSLog(@"%d-%d-%d",s1,s2,s3);

    

    int nowS = s1*60*60 + s2 *60 + s3;
