从XCode包中读取文本文件 [英] Reading Text File from XCode Bundle

问题描述

为什么我不能读取foo.rtf的内容？我已经把它放在XCode包中。 fileRoot仍然包含null。

  NSString * filePath = @foo; 
 NSString * fileRoot = [[NSBundle mainBundle] pathForResource：filePath ofType：@rtf]; 
 
 NSLog（@File root contains％@，fileRoot）; 
  

感谢任何人的帮助。

@TheAmateurProgrammer，谢谢你的图。我只是添加foo.rtf到束资源。 fileRoot的结果仍然为空。我还缺少什么步骤？

Target构建阶段中的Copy Bundle Resources现在包含foo.rtf。 （我不能插入图片，因为我还是一个新手）。

（我会添加阅读内容后，我可以得到fileRoot指向正确）你添加了这个文件，但它真的被复制到你的应用程序包中吗？

解决方案

请确保您的RTF文件被复制到你的资源中。

其次，你只得到rtf的路径，而不是rtf的内容。

 的NSString * fileRoot = [[一个NSBundle mainBundle] pathForResource：文件路径ofType：@ RTF]; 
 NSString * contents = [[[NSAttributedString alloc] initWithRTF：[NSData dataWithContentsOfFile：fileRoot] documentAttributes：NULL] string]; 
  

这将得到rtf的内容。

Why can't I read the content of foo.rtf? I've already put it in XCode bundle. fileRoot still contains null.

NSString* filePath = @"foo";
NSString* fileRoot = [[NSBundle mainBundle] pathForResource:filePath ofType:@"rtf"];       

NSLog(@"File root contains %@", fileRoot);

Appreciate anyone's help on this.

@TheAmateurProgrammer, Thank you for the diagram. I just added foo.rtf into the bundle resources. The result for fileRoot is still null. What step am I still missing?

Target's "Copy Bundle Resources" in Build Phases now contains foo.rtf. (I can't insert picture as I'm still a newbie).

(I will add the content reading after I can get fileRoot to point correctly).

解决方案

You added the file, but is it really copied to your application bundle?

Make sure your rtf file is copied into your resource.

Secondly, you're only getting the path of the rtf, and not the contents of the rtf.

NSString *fileRoot = [[NSBundle mainBundle] pathForResource:filePath ofType:@"rtf"]; 
NSString *contents = [[[NSAttributedString alloc] initWithRTF:[NSData dataWithContentsOfFile:fileRoot] documentAttributes:NULL] string];

That will get the contents of the rtf.
