Objective C: Reading text files

Question

I've done this before, but its not working for me now. I'm doing:

NSString* path = [[NSBundle mainBundle] pathForResource:@"test"                                                   ofType:@"txt"]; NSString* content = [NSString stringWithContentsOfFile:path                                               encoding:NSUTF8StringEncoding                                                  error:NULL]; NSLog(@"%@",path); 

and it returns (null) every time when I NSLog path and content. Can anyone see what I'm doing wrong?

Answer 1

content will be nil (which logs as '(null)') if you pass it a path it can't open. So your only issue is that the relevant instance of NSBundle is unable to find test.txt within the resources part of your application bundle.

You should:

1. check the file is in your Xcode project; and, if it is,
2. check it's included in the 'Copy Bundle Resources' phase underneath your selected Target (in the project tree view on the left in the normal Xcode window layout) and, if it is,
3. look inside the generated application bundle (find your product, right click, select 'Reveal in Finder', from Finder right click on the app and select 'Show Package Contents', then look for your file in there) to make sure that it's there.

If it's copied in but the relevant instance of NSBundle can't find it then something very strange is afoot.
