iOS 传入秒得到时分秒算法

传入 秒 得到 xx:xx:xx

-(NSString *)getMMSSFromSS:(NSString *)totalTime{
    
    NSInteger seconds = [totalTime integerValue];
    
    //format of hour
    NSString *str_hour = [NSString stringWithFormat:@"%02ld",seconds/3600];
    //format of minute
    NSString *str_minute = [NSString stringWithFormat:@"%02ld",(seconds%3600)/60];
    //format of second
    NSString *str_second = [NSString stringWithFormat:@"%02ld",seconds%60];
    //format of time
    NSString *format_time = [NSString stringWithFormat:@"%@:%@:%@",str_hour,str_minute,str_second];
    
    return format_time;
}

传入 秒 得到 xx分钟xx秒

-(NSString *)getMMSSFromSS:(NSString *)totalTime{
    
    NSInteger seconds = [totalTime integerValue];
    
    //format of minute
    NSString *str_minute = [NSString stringWithFormat:@"%ld",seconds/60];
    //format of second
    NSString *str_second = [NSString stringWithFormat:@"%ld",seconds%60];
    //format of time
    NSString *format_time = [NSString stringWithFormat:@"%@分钟%@秒",str_minute,str_second];
    
    NSLog(@"format_time : %@",format_time);
    
    return format_time;
}
