更新时间：2018-06-01  附上demo：https://gitee.com/liangsenliangsen/time_stamp_time_classification.git demo里有为NSObject写的一个分类，该分类具有将时间戳转化为时间的功能)
 
由于时间戳和时间的转换并不是很常用，所以在用到的时候也只是去网上找下代码。今天发现去网上找代码还是会耗费一定时间的，于是耗费时间找代码不如自己记录下代码以便下次使用。
上代码：
 
#pragma mark --- 将时间转换成时间戳
- (NSString *)getTimestampFromTime{
    NSDateFormatter *formatter = [[NSDateFormatteralloc] init];
    [formatter setDateStyle:NSDateFormatterMediumStyle];
    [formatter setTimeStyle:NSDateFormatterShortStyle];
    [formatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];// ----------设置你想要的格式,hh与HH的区别:分别表示12小时制,24小时制
    
    //设置时区,这个对于时间的处理有时很重要
    //例如你在国内发布信息,用户在国外的另一个时区,你想让用户看到正确的发布时间就得注意时区设置,时间的换算.
    //例如你发布的时间为2010-01-26 17:40:50,那么在英国爱尔兰那边用户看到的时间应该是多少呢?
    //他们与我们有7个小时的时差,所以他们那还没到这个时间呢...那就是把未来的事做了
    NSTimeZone* timeZone = [NSTimeZonetimeZoneWithName:@"Asia/Shanghai"];
    [formatter setTimeZone:timeZone];
    NSDate *datenow = [NSDatedate];//现在时间,你可以输出来看下是什么格式
    NSString *nowtimeStr = [formatterstringFromDate:datenow];//----------将nsdate按formatter格式转成nsstring
    NSLog(@"%@", nowtimeStr);
    // 时间转时间戳的方法:
    NSString *timeSp = [NSStringstringWithFormat:@"%ld", (long)[datenowtimeIntervalSince1970]];
    NSLog(@"timeSp:%@",timeSp);//时间戳的值
    return timeSp;
}
#pragma mark ---- 将时间戳转换成时间
- (NSString *)getTimeFromTimestamp{
    //将对象类型的时间转换为NSDate类型
    double time =1504667976;
    NSDate * myDate=[NSDatedateWithTimeIntervalSince1970:time];
    //设置时间格式
    NSDateFormatter * formatter=[[NSDateFormatteralloc]init];
    [formatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];
    //将时间转换为字符串
    NSString *timeStr=[formatterstringFromDate:myDate];
    return timeStr;
}
