NSDateFormatter dateFromString [英] NSDateFormatter dateFromString

问题描述

来自我的数据源的字符串的格式如下:

The string which comes from my data source is formatted like this:

2011-04-11 23:12:05

2011-04-11 23:12:05

// dateString comes from my data source, and look like I've said like this.
dateString = @"2011-04-11 23:12:05";

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"MMMM"];

NSDate *date = [formatter dateFromString:dateString];

当我在此类线程之后搜索Internet时，答案始终是dateString的格式错误.但是我的dateString是正确的字符串之一，对吧?

When I've searched internet after threads like these the answer has always been that the dateString had wrong format. But my dateString is one of the correct ones, right?

为什么日期返回nil?

Why does date returns nil?

推荐答案

日期格式字符串@"MMMM"表示您要解析的字符串是一个月的全名(一月"，十月"等).

A date format string of @"MMMM" means that the string you're trying to parse is the full name of a month ("January", "October", etc).
