如何在iOS 8.1中转换“ Tue，14 Jul 2015 15:00:00 +0000”

Question

我尝试通过这种方式将字符串转换为NSDate ：

NSString *str = @"Tue, 14 Jul 2015 15:00:00 +0000";

NSDateFormatter* formatter = [[NSDateFormatter alloc] init];

[formatter setDateFormat:@"EEE, dd MMM yyyy hh:mm:ss zzzz"];

NSDate* aDate = [formatter dateFromString:str];

[formatter setDateFormat:@"MMM dd,yyyy HH:mm:ss"];

NSLog(@"%@", [formatter stringFromDate:aDate]);

但这是空的，真正的方法是什么？

Answer 1

我已经尝试过了，它应该可以工作，结果是：

Jul 14,2015 16:00:00 (based on my time zone)

这是代码：

NSString *str = @"Tue, 14 Jul 2015 15:00:00 +0000";

NSDateFormatter* formatter = [[NSDateFormatter alloc] init];


[formatter setDateFormat:@"EEE, dd MMM yyyy HH:mm:ss Z"];

NSDate* aDate = [formatter dateFromString:str];

[formatter setDateFormat:@"MMM dd,yyyy HH:mm:ss"];
//formatter.timeZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"]; if you want to avoid converting the time to the current timezone

NSLog(@"%@", [formatter stringFromDate:aDate]);

日期格式模式

希望这对您有帮助-

NSString *str = @"Tue, 14 Jul 2015 15:00:00 +0000";
NSDateFormatter* formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"EEE, dd MMM yyyy HH:mm:ss ZZZ"];
NSDate* aDate = [formatter dateFromString:str];
[formatter setLocale:[NSLocale currentLocale]];
[formatter setDateFormat:@"MMM dd,yyyy HH:mm:ss"];
NSLog(@"%@", [formatter stringFromDate:aDate]);
