iphone - 将Textview文本转换为post请求参数--iphone开发

Question

我想通过发布请求将我的 TextView 内容传递到服务器，但我想我有编码问题。做|必须手动将空格转换为 + 或 %20 或者是否有 cocoa 或任何其他第三方支持的库？这……是小事吗？我在这个简单的步骤上坚持了几个小时! :)

看看如何在 http://www.rudis.net/content/2009/01/26/adding-percent-esacpes-cocoa 添加百分比转义的示例，引用作者的话:

One obvious way to do this is by calling NSString's

-(NSString*)stringByAddingPercentEscapesUsingEncoding:(NSStringEncoding)encoding

method. While this does a good job, it is not perfect and will miss things like "/", which may make some web services cry. The best way to do this encoding is to use:

CFStringRef CFURLCreateStringByAddingPercentEscapes (
   CFAllocatorRef allocator,
   CFStringRef originalString,
   CFStringRef charactersToLeaveUnescaped,
   CFStringRef legalURLCharactersToBeEscaped,
   CFStringEncoding encoding
);
