有谁知道为什么我在通过我的日期格式化程序后得到一个空日期值?
//Sets expire date for listing to String
NSString *expireDate = [[_itemDetailArray valueForKey:@"expireDate"]description]; //returns my date correctly
NSString *formattedStringDate = [NSString stringWithFormat:@"%@",[formatter dateFromString:expireDate]]; //comes out null
任何想法为什么?
