(DropdownTitleView
A simple and configurable "dropdown" view built for UINavigationItem.titleView.
Installation
Just add DropdownTitleView to your Podfile and pod install. Done!
pod 'DropdownTitleView'
Usage
Create an instance of DropdownTitleView, configure it, and set it as a UINavigationItem's titleView:
func viewDidLoad() {
super.viewDidLoad()
let titleView = DropdownTitleView()
titleView.configure(title: "Hello world!", subtitle: "Is this thing on?")
navigationItem.titleView = titleView
}
Add touch handling like you would any other UIControl:
func viewDidLoad() {
super.viewDidLoad()
// setup and set titleView
titleView.addTarget(
self,
action: #selector(onTitle),
for: .touchUpInside
)
}
@objc func onTitle() {
print("do something")
}
