accessing file saved to device writeToFile

Question

I'm saving my UITextView text into a file, test.txt

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"test.txt"];
[self.textBox.text writeToFile:path atomically:YES];
NSLog(path);

This works fine on the mac in the simulator, as it provides a library and I can just click on it to open the txt file. However, on the iPad, I"m not sure how to do this.

/var/mobile/Applications/10AC319A-D567-4DC6-B7C9-E53E71B82B89/Documents/test.txt

is where i'ts stored. I'm guessing the documents folder can't be accessed via ipad?

How do I pull this document within the app? Or save it in the app so that the user of the app can access it ?

Aside from the save button, I have another button called Read which should pull up test.txt somehow

I've started with

 -(IBAction)readAssignment:(id)sender{

    NSString* GetApplicationDocumentsDirectory(); {
        static NSString* documentsDirectory = nil;
        if (documentsDirectory == nil) {
            documentsDirectory = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"test.txt"];}

        self.textBox.text= [documentsDirectory stringByAppendingPathComponent:@"text.txt"];
    }

}




self.textBox.text= [documentsDirectory stringByAppendingPathComponent:@"text.txt"];

returns the file path, but how do i get it so that it displays the text.txt text that is saved into the textview?

But I know this isn't working/right.

Using NSString's stringWithContentsOfFile method, you can read back the text from a file.

NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"test.txt"];
NSError *error = nil;
[self.textBox.text writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:&error];
NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];
NSLog(@"myText: %@", myText);
