将 NSString 解析为 NSDate 时出现问题

发布于 2024-10-29 15:58:46 字数 453 浏览 3 评论 0原文

我有具有此值的 XML：

<LastModifiedOnDate>2011-04-02T00:00:00</LastModifiedOnDate>

我试图在 iPhone 上将其从 NSString 解析为 NSDate 但没有运气。

NSDateFormatter *formate = [[[NSDateFormatter alloc] init] autorelease];  
        [formate setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ss"];  
        //NSString *strConcat = @"2010-09-24 17:30:00";  
        NSDate *date = [formate dateFromString:string];

I have XML with this value:

<LastModifiedOnDate>2011-04-02T00:00:00</LastModifiedOnDate>

I am trying to parse this on iPhone from NSString to NSDate but have no luck.

NSDateFormatter *formate = [[[NSDateFormatter alloc] init] autorelease];  
        [formate setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ss"];  
        //NSString *strConcat = @"2010-09-24 17:30:00";  
        NSDate *date = [formate dateFromString:string];

您不需要格式字符串中的所有这些撇号。您唯一需要的是 T 周围的值。

NSDateFormatter *formate = [[[NSDateFormatter alloc] init] autorelease];  
[formate setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"];
// I recommend setting a timezone because it will use the system timezone and that
// can cause confusion with your data.  
// [formate setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSString *strConcat = @"2010-09-24T17:30:00";  
NSDate *date = [formate dateFromString:strConcat];
NSLog(@"Date: %@", date);  // remember NSDate default to current timezone when logging to console

如果您的字符串有秒的一小部分，则将 SSS 添加到您的字符串格式中： [formate setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS "];

有关日期格式的更多信息，请查看 Unicode 技术标准 # 35。

You don't need all those apostrophes in your format string. The only ones you need are around the T.

NSDateFormatter *formate = [[[NSDateFormatter alloc] init] autorelease];  
[formate setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"];
// I recommend setting a timezone because it will use the system timezone and that
// can cause confusion with your data.  
// [formate setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
NSString *strConcat = @"2010-09-24T17:30:00";  
NSDate *date = [formate dateFromString:strConcat];
NSLog(@"Date: %@", date);  // remember NSDate default to current timezone when logging to console

If you string have fraction of seconds, then add SSS to your string format: [formate setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS"];

For additional information on date formatting check out Unicode Technical Standard #35.

将您的 SetDataFormat 函数替换为下面的函数，并让我知道结果...

    [formate setDateFormat:@"yyyy-MM-ddTHH:mm:ss"];

Replace your's SetDataFormat function with below and let me know for the result ...

    [formate setDateFormat:@"yyyy-MM-ddTHH:mm:ss"];

NSString *string=@"2011-04-05T12:43:56.537";
NSDateFormatter *formate = [[[NSDateFormatter alloc] init] autorelease];  
[formate setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ss.SSS"];  
NSDate *date = [formate dateFromString:string];

它的工作..

NSString *string=@"2011-04-05T12:43:56.537";
NSDateFormatter *formate = [[[NSDateFormatter alloc] init] autorelease];  
[formate setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ss.SSS"];  
NSDate *date = [formate dateFromString:string];

its working..
