Retrieve file according to the language required

Question

I would like to get a legal doc based on the language that the user is currently using.

The code I have is this one:

     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
    NSString *libraryDirectory = [paths objectAtIndex:0];
if (sender == privacyPolicyButton) {
        ppPath = [libraryDirectory stringByAppendingPathComponent:@"privacy_policy.html"];

    } else if (sender == termsOfServiceButton) {
        ppPath = [libraryDirectory stringByAppendingPathComponent:@"terms.html"];

    } else if (sender == endUserButton) {
        ppPath = [libraryDirectory stringByAppendingPathComponent:@"eula.html"];

    }

    NSData *ppData = nil;
    policyView.scrollView.scrollEnabled = NO;

    [loadingIndicator startAnimating];
    policyView.hidden = closePolicyButton.hidden = NO;
    privacyPolicyButton.hidden = termsOfServiceButton.hidden = endUserButton.hidden = YES;

    ppData = [NSData dataWithContentsOfFile:ppPath];
    NSLog(@"%@", ppPath);

    [policyView loadData:ppData MIMEType:@"text/html" textEncodingName:@"utf-8" baseURL:nil];

I have a version of each document in spanish and in english, how can I tell the path to use the version in spanish?

Answer 1

The NSBundle class does this for you. Assuming your HTML files are part of the app's resource bundle, you can simply do:

NSString *htmlPath = [[NSBundle mainBundle] pathForResource:@"terms" ofType:@"html"];

This will give you the path to the proper terms.html file based on the user's locale/language setting.
