Answer 1

尝试这个：

本地到格林威治标准时间

NSString *dateString = @"Wed, 12 Dec 2012 09:08:30 GMT";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd MM yyyy hh:mma"];
NSTimeZone* sourceTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"BST"];
[dateFormatter setTimeZone:sourceTimeZone];
NSDate *dateFromString = [dateFormatter dateFromString:dateString];

Answer 2

好吧，我们需要先创建一个NSDate对象形式“Wed, 12 Dec 2012 09:08:30 GMT”

NSString *dateString = @"Wed, 12 Dec 2012 09:08:30 GMT";

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"EEE, dd MMM yyyy HH:mm:ss Z"];
[dateFormatter setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"EN"]];
NSDate *date = [dateFormatter dateFromString:dateString];

您可能会发现我设置的区域设置NSDateFormatter与本地化日期有关（月份和日期都是英文）。

现在您可以使用日期格式化程序在本地时区显示 dat：

[dateFormatter setLocale:[NSLocale systemLocale]];
[dateFormatter setTimeZone:[NSTimeZone systemTimeZone]];
NSString *localDateString = [dateFormatter stringFromDate:date];
