iOS巅峰之将时间戳转化成标准的时间格式

-

-(NSString *)setTime:(NSInteger)time{
    
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init] ;
    [formatter setDateStyle:NSDateFormatterMediumStyle];
    [formatter setTimeStyle:NSDateFormatterShortStyle];
    [formatter setDateFormat:@"YY-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
    
    NSDate *confromTimesp = [NSDate dateWithTimeIntervalSince1970:    time];
    NSString *confromTimespStr = [formatter stringFromDate:confromTimesp];
    return confromTimespStr;
    
}
