This group should be movable within the bar, as well as removable, and so is created as an optional group. The shapes group contains multiple items, and so uses the UIBarButtonItemGroup API to create the group. If you need a group with more than one item, you can use the UIBarButtonItemGroup method instead. Like fixed groups, movable groups cannot be removed, but can be moved.īecause of this, they require a customizationIdentifier so their position can be tracked and saved. The draw group contains a single item, so it also uses a convenience API, creatingMovableGroup (customizationIdentifier). If you need a fixed group with more than 1 item, you can use the UIBarButtonItemGroup method instead.įixed groups always appear first in the bar, and cannot be removed or moved by customization. The first group contains a single bar button item, so this example uses a convenience method of UIBarButtonItem, creatingFixedGroup(), to create it. In this example, there are 5 items in the bar, consisting of 4 groups. This allows for denser presentation when space is at a premium. Individual controls continue to be specified as UIBarButtonItems, but now are organized as UIBarButtonItemGroups. Overflow support is available in all modes, and allows the navigator style to indirectly support center items as well. IOS 16 takes advantage of this liberated space by allowing you to place additional controls in this region.Ĭenter items are part of a suite of changes to take better advantage of screen real estate, and include support for UIBarButtonItemGroup, customization support, and overflow. The browser and editor styles both free up a lot of space in the center of the bar. Editor UIs are often a destination, such as after selecting a document with a document picker, and so present a back button for easy access to that UI. Just like the browser style, the title is leading aligned. The editor style is optimized for when the primary function is document editing. The title is moved to the leading position in this styling. The browser style rearranges contents to be better optimized for interfaces where history matters as much as location, like in Files or Safari. The title is centered, there are leading and trailing bar button items, and a back button appears when there is more than 1 item on the stack. The default style, navigator, behaves exactly as a traditional UINavigationBar. UINavigationItem adds a style property, used to select from these styles: navigator, browser, and editor. UINavigationBar is used for many different purposes on iOS, and iOS 16 acknowledges that by providing new optimized UI for many of these cases. And, finally, updates to Search to help accelerate and polish the experience. Then features that are especially powerful for document based apps.

And to see how all these features work together, watch "Build a desktop class iPad app." In this video, I'll discuss changes to navigation that impact how you design your app for iOS 16.įirst are new features that make it easy to build more discoverable interfaces. The Edit menu has been overhauled, with a new interaction-based API that integrates with the menu system. The new Find and Replace UI is a snap to enable on built-in views and easy to add to custom ones. Updates to UINavigationBar allow you to take better advantage of screen real estate and build a great experience on all Apple platforms. UIKit adds many tools to help you meet these goals for your apps. iOS 16 brings advances to the tools used to design and build great apps, apps that bring more and better tools to the forefront and take advantage of all the hardware, both built in and attached.
