【iOS】OC-UTC日期字符串格式化

    NSLog(@"%@",[NSDate date]);

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

    [dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSSZ"];//此处注意时间格式

    //[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZ"];

    NSString * timeStr = @"2015-11-06T00:37:51.103Z";

    NSDate *localDate = [dateFormatter dateFromString:timeStr];

    NSLog(@"now Time = %@",[self getNowDateFromatAnDate:localDate]);

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

{

    //设置源日期时区

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