NSDateFormatter改变2小时的日期 为什么?
原标题:NSDateFormatter is shifting the date of 2 hours, why?

我想将以下 NSString 转换为 NSDate :

我使用的代码如下:

NSString *dateString = @"2013-04-01T22:00:00Z";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd T HH:mm:ss Z "];
NSDate *theDate = [dateFormatter dateFromString:dateString];

当我打印 theDate 我得到以下答案: 2013-04-01 20: 00: 00+0000

我想知道为什么时间是20: 00而不是22: 00, 你有什么想法吗?

谢谢!

最佳回答

由于日期格式没有指定时区 NSDateFormatter 使用您的本地时区。 您必须自己设置时区。 字符串中的 Z 是指格林尼治时间区 。

[dateFormatter setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
问题回答

在你的代码中尝试时区, 我已经在您默认的 TIME Zone 中尝试过。 它的工作正常。

NSString *dateString = @"2013-04-01T22:00:00Z";
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy-MM-dd T HH:mm:ss Z "];
    [dateFormatter setTimeZone:[NSTimeZone defaultTimeZone];
    NSDate *theDate = [dateFormatter dateFromString:dateString];
