Container view controller that simulates the behavior of a wheel to navigate through the view controllers. It's inspired by the Podcast app.
It inherits from UIViewController having two views inside their basic view, a wheel bar view and the view containing your custom content. The wheel bar view provides the selection controls to navigation through the view controllers.
Create your view controllers and assign them to the Wheel Bar Controller, like we do with Tab Bar Controllers.
Wheel Bar will use the title attribute of each view controller as the label for the buttons.
UIViewController *v1 = [[UIViewController alloc] init];
UIViewController *v2 = [[UIViewController alloc] init];
UIViewController *v3 = [[UIViewController alloc] init];
[v1 setTitle:@"Books"];
[v2 setTitle:@"Entertainment"];
[v3 setTitle:@"Medical"];
[v1.view setBackgroundColor:[UIColor redColor]];
[v2.view setBackgroundColor:[UIColor blueColor]];
[v3.view setBackgroundColor:[UIColor greenColor]];
PXLWheelBarController *controller = [[PXLWheelBarController alloc] init];
[controller setViewControllers:@[v1,v2, v3]];Wheel Bar view utilizes UIAppearance to make easy to customize several attributes, including:
- Font
- Color
- Highlighted Color
- Selection Indicator Image
- Backgroung Image
Using it to customize some attributes would be like:
[[PXLWheelBar appearance] setBackgroundImage:@"background-image.png"];
[[PXLWheelBar appearance] setSelectionIndicatorImage:[UIImage imageNamed:@"bullet.png"]];
[[PXLWheelBar appearance] setTitlesColor:[UIColor whiteColor]];
[[PXLWheelBar appearance] setTitlesHighlightedColor:[UIColor colorWithRed:.52f green:.75f blue:0.f alpha:1.f]];
[[PXLWheelBar appearance] setTitlesShadowColor:[UIColor colorWithWhite:0.f alpha:.6f]];
Deployed to iOS 5.0+ and it's ARC enabled.
