【iOS】OC-UTC日期字符串格式化

NSLog(@"%@",[NSDate

NSDateFormatter *dateFormatter = [[NSDateFormatter
alloc]

[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

- (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

//转为现在时间
