Reading Text File from Xcode Bundle

问题

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);

---

@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).

回答1:

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.

回答2:

First check that your file is present inside the bundle or not and if it present it must have same name as "foo.rtf".

You are getting nil because your file is not present directly inside in the bundle.

once you get the right file path you can get the content of your text file as a string by calling initWithContentsOfFile method on NSString class.
