从 JSON 日期格式获取 NSDate 日期(1268123281843)
在 Json.NET 4.5 之前,日期是使用 Microsoft 格式编写的:“/ Date(1198908717056)
/”。如果你的服务器以此格式发送日期,你可以使用以下代码将其序列化为 NSDate:
Objective-C
(NSDate*) getDateFromJSON:(NSString *)dateString
{
// Expect date in this format "/Date(1268123281843)/"
int startPos = [dateString rangeOfString:@"("].location+1;
int endPos = [dateString rangeOfString:@")"].location;
NSRange range = NSMakeRange(startPos,endPos-startPos);
unsigned long long milliseconds = [[dateString substringWithRange:range] longLongValue];
NSLog(@"%llu",milliseconds);
NSTimeInterval interval = milliseconds/1000;
NSDate *date = [NSDate dateWithTimeIntervalSince1970:interval];
// add code for date formatter if need NSDate in specific format.
return date;
}
