NSDateFormatter 时区（Etc/GMT）未解析 dateFromString

发布于 2024-11-19 05:33:08 字数 592 浏览 2 评论 0原文

我尝试通过以下代码将此 2011-07-11 13:28:59 Etc/GMT 转换为 NSDate，但结果为零。

NSString *dateString=@"2011-07-11 13:28:59 Etc/GMT";
NSDateFormatter *dateformatter=[[NSDateFormatter alloc] init];
[dateformatter setDateFormat:@"yyyy-MM-dd hh:mm:ss z"];
NSDate *purchaseDate = [dateformatter dateFromString:dateString];

此日期来自苹果服务器本身，用于应用内购买验证。我已经讨论了很多与时区相关的话题。但他们都没有展示如何转换这个 Etc/GMT

我已经尝试过 z zz zzz zzzz Z ZZ ZZZ ZZZZ

这里可能有什么问题。

I am getting nil for trying to convert this 2011-07-11 13:28:59 Etc/GMT into a NSDate by the following code

NSString *dateString=@"2011-07-11 13:28:59 Etc/GMT";
NSDateFormatter *dateformatter=[[NSDateFormatter alloc] init];
[dateformatter setDateFormat:@"yyyy-MM-dd hh:mm:ss z"];
NSDate *purchaseDate = [dateformatter dateFromString:dateString];

This date is coming from apple server itself for in-app purchase validation. I've gone about lot of threads with timezone. but none of them show how to convert this Etc/GMT

i have tried z zz zzz zzzz Z ZZ ZZZ ZZZZ

what might be the issue here.

正确的 dateFormat 是 yyyy-MM-dd HH:mm:ss VV 这是您应该用来解决问题的方法。

// 斯威夫特版本

    let DateString = "2016-01-21 00:29:09 Etc/GMT"
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss VV"
    var dateObject = dateFormatter.date(from: DateString)

// Swift Version

    let DateString = "2016-01-21 00:29:09 Etc/GMT"
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss VV"
    var dateObject = dateFormatter.date(from: DateString)

NSString *dateString=@"2011-07-11 13:28:59 Etc/GMT";
dateString = [dateString stringByReplacingOccurrencesOfString:@"Etc/GMT" withString:@"GMT"];
NSDateFormatter *dateformatter=[[NSDateFormatter alloc] init];
[dateformatter setDateFormat:@"yyyy-MM-dd HH:mm:ss z"];

// Or stuff....>>

NSDate *date = [dateformatter dateFromString: dateString];

dateformatter = [[[NSDateFormatter alloc] init] autorelease];
[dateformatter setDateFormat:@"yyyy-MM-dd hh:mm:ss a"];

NSString *convertedString = [dateformatter stringFromDate:date];
