字符串转换为格式yyyy-MM-dd HH:mm:ss Iphone [英] String to a Format yyyy-MM-dd HH:mm:ss Iphone

问题描述

我有一个nsstring，见下文

I have an nsstring ,see below

NSString *Mydate=@"9/8/2011";以月/日/年的格式.

NSString *Mydate=@"9/8/2011"; in month/day/year format.

我希望此字符串的格式为yyyy-MM-dd HH:mm:ss.

I want this string to be in the format yyyy-MM-dd HH:mm:ss.

例如:2011-09-08 15:51:57

for eg: 2011-09-08 15:51:57

所以我需要以更高的格式在标签中显示字符串.

so that i need to show the string in a label in the later format.

谢谢.
