如何将 NSString 转换为 NSDate? [英] How to turn a NSString into NSDate?

问题描述

我一直在绞尽脑汁，没有运气.有人可以告诉我如何转换这个字符串:

Ive been racking my brains with no luck. Could someone please tell me how i would convert this string:

2011-01-13T17:00:00+11:00"

"2011-01-13T17:00:00+11:00"

变成一个 NSDate?

into a NSDate?

推荐答案

Unicode 日期格式文档在 这里

The unicode date format doc is here

另外，对于你的情况，你可以试试这个:

Also, for your situation, you could try this:

// original string
NSString *str = [NSString stringWithFormat:@"2011-01-13T17:00:00+11:00"];

// convert to date
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
// ignore +11 and use timezone name instead of seconds from gmt
[dateFormat setDateFormat:@"YYYY-MM-dd'T'HH:mm:ss'+11:00'"];
[dateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"Australia/Melbourne"]];
NSDate *dte = [dateFormat dateFromString:str];
NSLog(@"Date: %@", dte);

// back to string
NSDateFormatter *dateFormat2 = [[NSDateFormatter alloc] init];
[dateFormat2 setDateFormat:@"YYYY-MM-dd'T'HH:mm:ssZZZ"];
[dateFormat2 setTimeZone:[NSTimeZone timeZoneWithName:@"Australia/Melbourne"]];
NSString *dateString = [dateFormat2 stringFromDate:dte];
NSLog(@"DateString: %@", dateString);

[dateFormat release];
    [dateFormat2 release];
