pod 'Persei', '~> 4.0'github "Yalantis/Persei" ~> 4.0For application targets that do not support embedded frameworks, such as iOS 7, Persei can be integrated by including source files from the Persei folder directly, optionally wrapping the top-level types into
struct Perseito simulate a namespace. Yes, this sucks.
- Add Persei as a submodule by opening the Terminal,
cd-ing into your top-level project directory, and entering the commandgit submodule add https://github.com/yalantis/Persei.git - Open the
Perseifolder, and dragPersei.xcodeprojinto the file navigator of your app project. - In Xcode, navigate to the target configuration window by clicking on the blue project icon, and selecting the application target under the "Targets" heading in the sidebar.
- Ensure that the deployment target of
Persei.frameworkmatches that of the application target. - In the tab bar at the top of that window, open the "Build Phases" panel.
- Expand the "Target Dependencies" group, and add
Persei.framework. - Expand the "Link Binary With Libraries" group, and add
SideMenu.framework - Click on the
+button at the top left of the panel and select "New Copy Files Phase". Rename this new phase to "Copy Frameworks", set the "Destination" to "Frameworks", and addPersei.framework.
import Perseilet menu = MenuView()
tableView.addSubview(menu)In order to set items you need to instantiate array of MenuItem:
let items = feedModes.map { mode: SomeYourCustomFeedMode -> MenuItem in
return MenuItem(image: mode.image)
}
menu.items = itemsYou can specify selected item manually:
menu.selectedIndex = 3Note, that selectedIndex declared as Int? and will be nil in case of menu.items = nil.
Also, you can implement MenuViewDelegate to be notified about selection change:
// during init
menu.delegate = self
// actual implementation
extension FeedViewController: MenuViewDelegate {
func menu(menu: MenuView, didSelectItemAt index: Int) {
dataSource.mode = feedModes[index] // alter mode of dataSource
tableView.reload() // update tableView
}
}Menu can be reveal as a result of button tap:
func menuButtonSelected(sender: UIControl) {
menu.revealed = !menu.revealed
// or animated
menu.setRevealed(true, animated: true)
}Use contentViewGravity to control sticking behavior. There are 3 available options:
- Top:
contentViewsticked to the top position of the view - Center:
contentViewis aligned to the middle of the streched view - Bottom:
contentViewsticked to the bottom
MenuItem declares set of attributes, that allow you to customize appearance of items:
struct MenuItem {
var image: UIImage // default image
var highlightedImage: UIImage? // image used during selection
var backgroundColor: UIColor // default background color
var highlightedBackgroundColor: UIColor // background color used during selection
var shadowColor: UIColor // color of bottom 2px shadow line
}Also you're free to configure background of MenuView by utilizing backgroundColor or backgroundImage. Note, that image should be resizeable:
let menu = MenuView()
menu.backgroundImage = UIImage(named: "top_menu_background")- Can I place the UIImageView instead?
- Sure! Just subclass / use
StickyHeaderViewdirectly. It offers layout, positioning and reveal control. All you have to do is to assign your custom view (animated nian-cat UIImageView) tocontentView:
let headerView = StickyHeaderView()
let imageView = UIImageView(...)
headerView.contentView = imageViewObviously, your custom view can have heigh different from default:
headerView.contentHeight = image.size.heightAs well as control distance to trigger open/close of the header:
headerView.threshold = 0.5Threshold is a float value from 0 to 1, specifies how much user needs to drag header for reveal.
We’d be really happy if you sent us links to your projects where you use our component. Just send an email to [email protected] And do let us know if you have any questions or suggestion regarding the animation.
P.S. We’re going to publish more awesomeness wrapped in code and a tutorial on how to make UI for iOS (Android) better than better. Stay tuned!
