![]() YacktmanĪpplication Architecture Fundamentals - Bob Tabor. Here are some great resources to help dive into MVC, Separation of Concerns, Architecture and more!Ĭocoa Design Patterns - Erik M. Changes that happen in the model are also sent from the Controller to the View. Users interacting with elements in the view result in requests made to classes(objects) in the Controller layer, which in turn may request changes to information in the Model. They contain the Buttons, Text boxes, WebViews, etc.Ĭontroller - The purpose of the classes in this layer is to decouple the Model from the Views. are the part of the application the user interacts with. View - The elements in this layer, whether they be classes, story boards, xibs, etc. It should be able to stand alone with out dependencies on the View or Controller layers. The Model is the layer that makes the application valuable. One set of classes may contain network communication logic. One set of classes may contain data persistence logic. One set of classes may contain calculation logic. Model - The classes in this layer contain the special “business logic” and address the problem domain that the app is all about. See the LICENSE file for more info.Some notes that might help in the description of MVC. TEQuickPageViewController is available under the MIT license. Feel free to open it up and play around! License TEQuickPageViewController.xcodeproj is a simple iOS app making use of the TEQuickPageViewController class. It should be easy to see if you have a loop in your chain, and remove the problem segue. ![]() If you have a cycle in your chain of pages (such as connecting -> -> ), this will result in an infinite loop when establishing the array of pages, and our app will crash. You can now change the identifier for your segues to this string. To specify your own identifier, just set the "Segue Id" attribute on your TEQuickPageViewController. Custom Segue Identifierīy default, your page segues need an identifier of "page", but this may not be desirable. When disabled, the user will not be able to swipe backwards from the first page or forwards from the last page. The Wrap Around attribute in your TEQuickPageViewController's attributes allows your pages to "wrap" from the end back to the beginning. These control the color of the unselected page indicators and the currently selected page indicators respectively. You may have seen in the above screenshot for Extended Pages that there are color options for "Indicator Tint" and "Indicator Current". Of course, you may need to change the scroll indicator colors Changing Indicator Colors Just open the Attributes inspector of your TEQuickPageViewController and set "Extended Page" On.īingo! No more ugly bar. To get rid of this, you can set up your TEQuickPageViewController to extend your pages across the entire view. You'll probably have noticed the ugly black bar that appears at the bottom of your view when using the scroll transition. This will create a chain of pages in your storyboard.Īdditional Features Extended Views (get rid of the black bar!) To add a second page, just drag another View Controller into your view and add another custom segue with the same settings, this time from your first page. Set the segue's class to TEQuickPageViewSegue and the Identifier to "page".Add a custom segue between your Page View Controller and the new View Controller.Drag a View Controller into your Storyboard.To add a page to your sequence of pages, you will need to connect it to your controller or preceding pages: ![]() In the Page View Controller's Identity Inspector, set the class to TEQuickPageViewController.Drag a Page View Controller into your Storyboard.To include the required source directly, just add these files to your project:įirst, you'll need to prepare your UIPageViewController:
