SwiftyMenu is simple yet powerfull drop down menu component for iOS. It allow you to have drop down menu that doesn't appear over your views, which give you awesome user experience.
- Xcode 10.2
- Swift 5
- iOS 10
CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate SwiftyMenu into your Xcode project using CocoaPods, specify it in your Podfile
:
pod 'SwiftyMenu', '~> 1.0.1'
- Automatically in Xcode:
- Click File > Swift Packages > Add Package Dependency...
- Use the package URL
https://github.com/KarimEbrahemAbdelaziz/SwiftyMenu
to add TimelaneCombine to your project.
- Manually in your Package.swift file add:
.package(url: "https://github.com/KarimEbrahemAbdelaziz/SwiftyMenu", from: "1.0.1")
SwiftyMenu
supports initialization from Storyboard
and Code
.
Setup your view controller:
// Connect view in storyboard with you outlet
@IBOutlet private weak var dropDownMenu: SwiftyMenu!
Then connect IBOutlet
to Storyboard
, and connect the Height
Constraints of the menu as shown below.
- Init
SwiftyMenu
/// Init SwiftyMenu from Code
let dropDownCode = SwiftyMenu(frame: CGRect(x: 0, y: 0, width: 0, height: 40))
- Add
SwiftyMenu
asSubview
/// Add it as subview
view.addSubview(dropDownCode)
- Setup Constraints
/// Add constraints to SwiftyMenu
/// You must take care of `hegiht` constraint, please.
dropDownCode.translatesAutoresizingMaskIntoConstraints = false
let horizontalConstraint = NSLayoutConstraint(item: dropDownCode, attribute: NSLayoutConstraint.Attribute.centerX, relatedBy: NSLayoutConstraint.Relation.equal, toItem: view, attribute: NSLayoutConstraint.Attribute.centerX, multiplier: 1, constant: 0)
let topConstraint = NSLayoutConstraint(item: dropDownCode, attribute: NSLayoutConstraint.Attribute.top, relatedBy: NSLayoutConstraint.Relation.equal, toItem: otherView, attribute: NSLayoutConstraint.Attribute.top, multiplier: 1, constant: 64)
let widthConstraint = NSLayoutConstraint(item: dropDownCode, attribute: NSLayoutConstraint.Attribute.width, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 255)
dropDownCode.heightConstraint = NSLayoutConstraint(item: dropDownCode, attribute: NSLayoutConstraint.Attribute.height, relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, attribute: NSLayoutConstraint.Attribute.notAnAttribute, multiplier: 1, constant: 40)
NSLayoutConstraint.activate(
[
horizontalConstraint,
topConstraint,
widthConstraint,
dropDownCode.heightConstraint
]
)
To configure SwiftyMenu
DataSource, you'll need to prepare your Model
to be able to presented and retrived from the menu. Then, create and assign the DataSource to SwiftyMenu
.
We are supporting Generic Data Source, all you have to do is conforming to our Generic Protocol on which type you want to add to the menu.
- Example of
String
extension String: SwiftyMenuDisplayable {
public var displayableValue: String {
return self
}
public var retrivableValue: Any {
return self
}
}
- Example of custom
Struct
struct MealSize {
let id: Int
let name: String
}
extension MealSize: SwiftyMenuDisplayable {
public var displayableValue: String {
return self.name
}
public var retrievableValue: Any {
return self.id
}
}
- Create an
Array
of your models
/// Define menu data source
/// The data source type must conform to `SwiftyMenuDisplayable`
private let dropDownOptionsDataSource = [
MealSize(id: 1, name: "Small"),
MealSize(id: 2, name: "Medium"),
MealSize(id: 3, name: "Large"),
MealSize(id: 4, name: "Combo Large")
]
- Assign it to
SwiftyMenu
DataSource property
dropDownCode.items = dropDownOptionsDataSource
SwiftyMenu
supports 2 ways to capture the selected items, Delegate
and Closure
s. You can use one or both of them at the same time.
- Conform to
SwiftyMenu
Delegate protocol
extension ViewController: SwiftyMenuDelegate {
// Get selected option from SwiftyMenu
func swiftyMenu(_ swiftyMenu: SwiftyMenu, didSelectItem item: SwiftyMenuDisplayable, atIndex index: Int) {
print("Selected item: \(item), at index: \(index)")
}
// SwiftyMenu drop down menu will expand
func swiftyMenu(willExpand swiftyMenu: SwiftyMenu) {
print("SwiftyMenu willExpand.")
}
// SwiftyMenu drop down menu did expand
func swiftyMenu(didExpand swiftyMenu: SwiftyMenu) {
print("SwiftyMenu didExpand.")
}
// SwiftyMenu drop down menu will collapse
func swiftyMenu(willCollapse swiftyMenu: SwiftyMenu) {
print("SwiftyMenu willCollapse.")
}
// SwiftyMenu drop down menu did collapse
func swiftyMenu(didCollapse swiftyMenu: SwiftyMenu) {
print("SwiftyMenu didCollapse.")
}
}
- Assign
SwiftyMenu
delegate
dropDownCode.delegate = self
You can use callbacks to know what happen:
/// SwiftyMenu also supports `CallBacks`
dropDownCode.didSelectItem = { menu, item, index in
print("Selected \(item) at index: \(index)")
}
dropDownCode.willExpand = {
print("SwiftyMenu Will Expand!")
}
dropDownCode.didExpand = {
print("SwiftyMenu Expanded!")
}
dropDownCode.willCollapse = {
print("SwiftyMenu Will Collapse!")
}
dropDownCode.didCollapse = {
print("SwiftyMenu Collapsed!")
}
Having an amazing drop down menu is essential. So, there're a lot of UI customization for SwiftyMenu
(More to be added soon).
To configure UI customization for SwiftyMenu
:
- Create
SwiftyMenuAttributes
property
private var codeMenuAttributes = SwiftyMenuAttributes()
- Assign it to
SwiftyMenu
/// Configure SwiftyMenu with the attributes
dropDownCode.configure(with: codeMenuAttributes)
Also before assigning it to SwiftyMenu
you could customize the menu look using following attributes.
attributes.placeHolderStyle = .value(text: "Please Select Size", textColor: .lightGray)
attributes.textStyle = .value(color: .gray, separator: " & ", font: .systemFont(ofSize: 12))
attributes.scroll = .disabled
attributes.multiSelect = .disabled
attributes.hideOptionsWhenSelect = .enabled
attributes.rowStyle = .value(height: 40, backgroundColor: .white, selectedColor: .white)
/// Rounded Corners
attributes.roundCorners = .all(radius: 8)
/// Menu Maximum Height
attributes.height = .value(height: 300)
/// Menu Border
attributes.border = .value(color: .gray, width: 0.5)
/// `SwiftyMenu` have default arrow
attributes.arrowStyle = .value(isEnabled: true)
attributes.separatorStyle = .value(color: .black, isBlured: false, style: .singleLine)
attributes.headerStyle = .value(backgroundColor: .white, height: 40)
attributes.accessory = .disabled
attributes.expandingAnimation = .linear
attributes.expandingTiming = .value(duration: 0.5, delay: 0)
attributes.collapsingAnimation = .linear
attributes.collapsingTiming = .value(duration: 0.5, delay: 0)
