objective-c - 对 NSDateFormatter 的 dateFromString 调用返回 nil

Question

下面代码中的日期变量返回 nil。我找不到日期格式有任何问题，有人可以帮忙吗？

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"EEE MMM dd HH:mm:ss zzz yyyy"];

NSString *dateString = [[NSString alloc] initWithFormat:@"%@", @"Mon Apr 05 04:37:28 UTC 2010"];
NSDate *date = [formatter dateFromString:dateString];

Answer 1

尝试

NSDate *date = [formatter dateFromString:@"Mon Apr 05 04:37:28 GMT 2010"];

或者

NSDate *date = [formatter dateFromString:@"Mon Apr 05 04:37:28 +0000 2010"];
