如何解码iPhone中的字符串

发布于 2024-09-05 13:43:20 字数 432 浏览 5 评论 0原文

我想解码我的字符串。我使用了解析并从 RSS feed 中获取了一个字符串。在字符串中，不允许使用这些特殊字符 &、<、>在我的应用程序中。在服务器端对这些字符进行编码并将其赋予字符串。所以现在我得到了这样的字符串，

 Actual String : <Tom&Jerry>  (only these characters are not allowed in node data & < >).

 After Encoding:  %3CTom%26Jerry%3E.

但我需要显示该字符串是

                  <Tom&Jerry>

那么我如何解码该字符串。

请帮帮我。

谢谢。

I want to decode my string. I have used parsing and get a string from RSS feed. In a string these special characters are not allowed &,<,> in my app. In server side encoding those characters and give it to the string. So now i got the string like,

 Actual String : <Tom&Jerry>  (only these characters are not allowed in node data & < >).

 After Encoding:  %3CTom%26Jerry%3E.

使用 -stringByReplacingPercentEscapesUsingEncoding： 方法。

[@"%3CTom%26Jerry%3E"
 stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

Use the -stringByReplacingPercentEscapesUsingEncoding: method.

[@"%3CTom%26Jerry%3E"
 stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

查找

- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encoding

Or 通过示例：

NSString *input = @"Hello%20World";
NSString *output = [text stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(@"%@ becomes %@",input,output);

Log: Hello%20World becomes Hello World

Look for

- (NSString *)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encoding

Or by example:

NSString *input = @"Hello%20World";
NSString *output = [text stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(@"%@ becomes %@",input,output);

Log: Hello%20World becomes Hello World

我得到了答案，我的代码是，

     NSString *currentString =@"%3CTom%26Jerry%3E";

     NSString  * decodeString = [currentString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    lblTitle.text = decodeString;

谢谢。

I got the answer and my code is,

     NSString *currentString =@"%3CTom%26Jerry%3E";

     NSString  * decodeString = [currentString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    lblTitle.text = decodeString;

Thanks.
