- Fixes for all warnings.
- Tab item text is using a system font size of 11, instead of a bold system font size 11.
- Tab item title color is using tintColor for both states, instead of some grayish (masking).
- Changed spacing between tab image and text to fit better with imageset.
- Add backgroundColor property to SPStackedNavigationController, overriding the background image of the controller.
- Add sp_tintedImageWithColor: to the UIImage category.
- Add backgroundColor property to SPSideTabBar, overriding the background pattern.
- Added roundCorners property to SPSideTabBar, to turn on and off the corner radius applied to the tab bar. (Spotify has turned it off now too).
- Add useTintedImages property to change generation of tab images from using Spotify glow masks to using pure tints.
Currently, the code still contains Spotify (or now, Aura) specific code. Mostly colors. I might filter these out, but it is not always very simple to do, especially with the UIImage category.
Spotify seems to not update the code in the repository:
- The app does not use rounded corners anymore
- Nor does it have a background image in the nav controller.
- And it works fine with the status bar of iOS7 (the code did not without modification.)
SPStackedNavigationController is a UINavigationController drop-in replacement, which represents its content in stacks of panes, rather than one at a time. This interface trend was started by Loren Brichter in Tweetie for iPad, and has spread to many apps in many variations since.
There are two main advantages to this approach:
- You can display two pieces of main content at once, allowing you to navigate in one while using content in the other.
- Navigation is direct instead of indirect, which is faster and more intuitive to use. You actually grab the UI and pull it to where you want it. In contrast, a standard navigation controller requires you to find and tap a button with an abstract "back" concept.
The main drawback is that you should no longer use horizontal gestures, as they will interfere with navigation, or the other way around.
At Spotify, we use this style for navigation in our iPad app. We are very proud of the outcome, and are contributing it back to the community, in hopes that others will find it as useful as we do. This code has been used for several years at Spotify and should be very stable.
In our implementation, a page can either be "full size" and thus cover the whole width of the parent container (which we use for the root view controllers in our stacks), or half-size (exactly two will fit in landscape, or one and a half in portrait).
In addition, SPSideTabController is a drop-in replacement for UITabBarController, but with tabs along the left side rather than along the bottom. This is one of the UIs that are commonly combined with a stacked navigation.
Extra tab bar items can be added along the bottom (e g for "Settings"), and the whole bottom of the screen can have an attachment, which we use to show the currently playing track in Spotify.
- Pull in "include", "Sources" and "Graphics" into your main project.
- Go to your project settings, then Build Settings for your app target, and change "Header Search Paths" to include and "{your path to SPStackedNav}/include".
- #import <SPStackedNav/SPStackedNav.h> either from your prefix header, or the source file where you want to use these classes.
See Examples/StackExample for some example usage.
