XZ_iOS之时间戳和时间字符串的一个转换

1、时间字符串“2015-03-10 12:00”转换成时间戳

NSString*timeStr =

2015-03-10 12:00"
NSDateFormatter*formatter = [[NSDateFormatteralloc]init];
[formattersetDateStyle:NSDateFormatterMediumStyle];
[formattersetTimeStyle:NSDateFormatterShortStyle];
[formattersetDateFormat:@"YYYY-MM-dd
HH:mm"];
NSDate*dateValue = [formatter

dateFromString:timeStr];
NSString*timeSp = [NSStringstringWithFormat:@"%ld",
(long)       [dateValuetimeIntervalSince1970]];
2、时间戳“1438146673000”转换成字符串

NSTimeInterval timeInt=[time doubleValue];
NSDate *detaildate=[NSDatedateWithTimeIntervalSince1970:timeInt];
NSDateFormatter *dateFormatter = [[NSDateFormatteralloc] init];

[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm"];
NSString *currentDateStr = [dateFormatter stringFromDate:
detaildate];
