iOS时间相差8小时

获取时间相差8小时的处理办法：

现将需要转换的时间转换为nsdata：timeUtc

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

[dateFormatter setDateFormat:@"YYYY/MM/dd hh:mm:ss"];

NSDate *te    = [self getNowDateFromatAnDate:timeUtc];

NSString *str = [NSString stringWithFormat:@"%@",te];

dateString    = [str substringToIndex:19];

- (NSDate *)getNowDateFromatAnDate:(NSDate *)anyDate

{

//设置源日期时区

NSTimeZone* sourceTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"UTC"];//或GMT

//设置转换后的目标日期时区

NSTimeZone* destinationTimeZone = [NSTimeZone localTimeZone];

//得到源日期与世界标准时间的偏移量

NSInteger sourceGMTOffset = [sourceTimeZone secondsFromGMTForDate:anyDate];

//目标日期与本地时区的偏移量

NSInteger destinationGMTOffset = [destinationTimeZone secondsFromGMTForDate:anyDate];

//得到时间偏移量的差值

NSTimeInterval interval = destinationGMTOffset - sourceGMTOffset;

//转为现在时间

NSDate* destinationDateNow = [[NSDate alloc] initWithTimeInterval:interval sinceDate:anyDate];

return destinationDateNow;

}
