Issue using Variables to load PDF File in iphone SDK

[lolcott]

Hi all, I'm trying to load a PDF in my App:

Using this works fine

    pdfURL=[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource: @"myFile" ofType:@"pdf"]];

            controller.pdfUrl = pdfURL;
            [self.navigationController pushViewController:controller animated:YES];
            [controller release];

However, i would like to be able to call the file from a NSString variable. i.e. Take out the @"myFile" and insert NSString fileName. Any idea what i'm doing wrong?

Thanks in advance!

Should be able to do it. I assume because the code you sent works that you have a file named 'myFile.pdf' so if you you want to get a new file you should just put in the new file name and it should work providing the file is known to the project.

new code code is

 pdfURL=[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource: fileName ofType:@"pdf"]];

And i get a: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[NSURL initFileURLWithPath:]: nil string parameter' error in console.

I put a NSLog right before to check for an empty fileName. It is not empty. Thank you for taking a look! -L
