Join Kevin Favro for an in-depth discussion in this video Creating custom restrictions, part of iOS App Development: Accessibility.
- [Instructor] In this video,…we're going to take a look at how we,…as developers,…can create custom restrictions…that our users can set…while running our app within a guided access session.…We'll need to start in our AppDelegate…by adopting the UIGuidedAccessRestrictionDelegate…on line 12.…Next, let's open up a new line on line 11…and let's add a simple struct…that will allow us to easily refer…to our custom restriction.…We'll call our struct a GuidedAccessRestrictions.…
And for now it'll have one member.…It'll be a static constant…that we'll call FavoriteRestriction…and we'll set that to a string.…We'll use reverse DNS notation…to ensure it's unique throughout the entire system.…In order to create custom restrictions…we'll need to implement three methods…and populate one variable property.…Go ahead and scroll to the very bottom…and open up a new line on line 47.…The property we need to override…is the guidedAccessRestrictionIdentifiers property.…
We'll pass it an array of our custom restrictions.…For now,…we just have the one favorite restriction.…
