iOS中处理日期时间,我们可以使用以下方法,请注意地区时差的问题,代码及效果如下:

//2015-09-15 18:09:28 - 1442311768

NSLog(@"2015-09-15 18:09:28");

NSDate *createTimesp =

[NSDate dateWithTimeIntervalSince1970:1442311768+28800];

NSLog(@"%@",createTimesp);

 

NSString *str=@"1442311768";//时间戳

NSTimeInterval time = [str doubleValue]+28800;//因为时差问题要加8小时 == 28800 sec

NSDate *detaildate=[NSDate dateWithTimeIntervalSince1970:time];

NSLog(@"%@",[detaildate description]);

 

//实例化一个NSDateFormatter对象

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

//设定时间格式,这里可以设置成自己需要的格式

[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

NSString *currentDateStr = [dateFormatter stringFromDate:[NSDate dateWithTimeIntervalSince1970:1442311768]];

NSLog(@"%@",currentDateStr);

//NSLog(@"%ld",(long)[[NSDate date] timeIntervalSince1970]);

运行效果:
