Easily display third-party licenses in your app.
Create an instance of FFLicensesViewController as rootViewController of a UINavigationController:
FFLicensesViewController *licensesViewController = [[FFLicensesViewController alloc] init];
UINavigationController *licensesNavigationController = [[UINavigationController alloc] initWithRootViewController:licensesViewController];
Create your FFLicense instances:
NSBundle *bundle = [NSBundle mainBundle];
BOOL iOS7 = [UIDevice currentDevice].systemVersion.floatValue >= 7.0f;
FFLicense *fullscreenConstraint = [FFLicense licenseWithTitle:@"NSLayoutConstraint+FullscreenConstraints" filePath:[bundle URLForResource:@"NSLayoutConstraint+FullscreenConstraints_License" withExtension:((iOS7) ? @"rtf" : @"txt")]];
FFLicense *animatedTableUpdate = [FFLicense licenseWithTitle:@"UITableView+AnimatedArrayUpdate" filePath:[bundle URLForResource:@"UITableView+AnimatedArrayUpdate_License" withExtension:@"txt"]];
Set the licenses property of the FFLicensesViewController and present it (modally in this case):
licensesViewController.licenses = @[fullscreenConstraint, animatedTableUpdate];
[self presentViewController:licensesViewController animated:YES completion:nil];
If you already have a UINavigationController you can of course just create an instance of FFLicensesViewController, set the licenses property and push it onto the navigation stack:
FFLicensesViewController *licensesViewController = [[FFLicensesViewController alloc] init];
licensesViewController.licenses = @[fullscreenConstraint, animatedTableUpdate];
[self.navigationController pushViewController:licensesViewController animated:YES];
Also have a look at the sample project.
As of iOS 7 you can use rtf files and it will turn them into NSAttributedString.
Although the FFLicense always returns NSAttributedString they only have attributes on iOS 7+. On iOS 6 it will just load a normal string and turn it into a NSAttributedString without any attributes.
As seen in the example above (as well as the sample project) you can just set different file extensions depending on which iOS version you run on. This, however, requires two versions of each license file.
