Question

I can use a string literal like @"content", but I think it’s a waste of memory. Is there a custom solution for this situation?

I’m a new Xcoder, so may be this is not a good question, but I’m very confuse about the use of NSString…

Put the text in a file. Let’s say you name the file userAgreement.txt. Make sure the file is part of your target (check the Target Membership section of the File Inspector while you have the file open in the primary editor).

Read the contents of the file at runtime like this:

NSString *path = [[NSBundle mainBundle] pathForResource:@"userAgreement" ofType:@"txt"];
NSString *userAgreement = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:NULL];

A feature of this approach is that you can localize the file, and this code will automatically pick up the appropriate version for the user’s locale.

Note that if you want to use a custom end-user license agreement (EULA), and you want to put this app in the App Store, you must enter the EULA in your app configuration in iTunes Connect.
