如何将字符串转换为日期和字符串中的日期?
问题描述：
我的输入字符串是
NSString *inputString=@"15 February 2012 17:05";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"dd MMMM YYYY HH:mm"];
NSDate *dateVal = [dateFormat dateFromString:inputString];
NSDateFormatter *dateFormat2 = [[NSDateFormatter alloc] init];
[dateFormat2 setDateFormat:@"MM/dd/YYYY HH:mm"];
NSString *outputString = [dateFormat2 stringFromDate:dateVal];
[dateFormat release];
[dateFormat2 release];
我有以下日期 outputString = 12/25/2011 17:05
I got the following date outputString=12/25/2011 17:05
但这应该是2012年2月15日17:05 ..我在哪里弄错了?
But it should be 02/15/2012 17:05..Where did i do the mistake?
答
您为日期格式使用了错误的格式，也无需创建NSDateFormatter的另一个实例-
You are using wrong format for date format and also there is no need to create another instance of NSDateFormatter -
NSString *inputString=@"15 February 2012 17:05";
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"dd MMMM yyyy HH:mm"];
NSDate *dateVal = [dateFormat dateFromString:inputString];
[dateFormat setDateFormat:@"MM/dd/yyyy HH:mm"];
NSString *outputString = [dateFormat stringFromDate:dateVal];
