Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate RSSelectionMenu into your Xcode project using Carthage, specify it in your Cartfile:

github "rushisangani/RSSelectionMenu" ~> 5.2.1

Then follow below steps:

• Run carthage update to build the framework.
• Set Framework search path in target build settings : Build Settings -> Framework Search Paths : $(PROJECT_DIR)/Carthage/Build/iOS
• Add RSSelectionMenu.framework in Embedded Binaries.
• Add RSSelectionMenu.framework in Linked Frameworks and Libraries.

Usage

Simple Selection List

let simpleDataArray = ["Sachin", "Rahul", "Saurav", "Virat", "Suresh", "Ravindra", "Chris"]
var simpleSelectedArray = [String]()

// Show menu with datasource array - Default SelectionType = Single
// Here you'll get cell configuration where you can set any text based on condition
// Cell configuration following parameters.
// 1. UITableViewCell   2. Object of type T   3. IndexPath

let selectionMenu =  RSSelectionMenu(dataSource: simpleDataArray) { (cell, object, indexPath) in
    cell.textLabel?.text = object
    
    // Change tint color (if needed)
    cell.tintColor = .orange
}

// set default selected items when menu present on screen.
// Here you'll get onDidSelectRow

selectionMenu.setSelectedItems(items: simpleSelectedArray) { (text, isSelected, selectedItems) in

    // update your existing array with updated selected items, so when menu presents second time updated items will be default selected.
    self.simpleSelectedArray = selectedItems
}

// auto dismiss
selectionMenu.dismissAutomatically = false      // default is true

// show as PresentationStyle = Push
selectionMenu.show(style: .Push, from: self)

Multiple Selection List

let selectionMenu = RSSelectionMenu(selectionType: .Multiple, dataSource: dataArray, cellType: .Basic) { (cell, object, indexPath) in
    cell.textLabel?.text = object
}

• Set Maximum selection limit (Optional)

selectionMenu.setSelectedItems(items: selectedDataArray, maxSelected: 3) { (text, selected, selectedItems) in
}

Presentation Style - Formsheet, Popover, Alert, Actionsheet

// show as Formsheet
selectionMenu.show(style: .Formsheet, from: self)

// show as Popover
selectionMenu.show(style: .Popover(sourceView: sourceView, size: nil), from: self)

// show as Alert
selectionMenu.show(style: .Alert(title: "Select", action: nil, height: nil), from: self)

// Show as Actionsheet
selectionMenu.show(style: .Alert(title: nil, action: "Done", height: nil), from: self)

Event Handlers

On Dismiss

selectionMenu.onDismiss = { selectedItems in
    self.selectedDataArray = selectedItems
    
    // perform any operation once you get selected items
}

On WillAppear

selectionMenu.onWillAppear = {
    /// do something..
}

Customization

SearchBar

• You'll get notified via handler, when user starts typing in searchbar.

// show searchbar
selectionMenu.showSearchBar { (searchtext) -> ([String]) in

  // return filtered array based on any condition
  // here let's return array where name starts with specified search text

  return self.dataArray.filter({ $0.lowercased().hasPrefix(searchText.lowercased()) })
}

Cell Style - Right Detail or Sub Title

let selectionMenu = RSSelectionMenu(selectionType: .Single, dataSource: dataArray, cellType: .RightDetail) { (cell, object, indexPath) in

    // here you can set any text from object
    // let's set firstname in title and lastname as right detail

    let firstName = object.components(separatedBy: " ").first
    let lastName = object.components(separatedBy: " ").last

    cell.textLabel?.text = firstName
    cell.detailTextLabel?.text = lastName
}

selectionMenu.setSelectedItems(items: selectedDataArray) { (text, selected, selectedItems) in
    self.selectedDataArray = selectedItems
}

// show as default
selectionMenu.show(from: self)

Custom Cells

• Provide custom cell with xib file name and cell identifier.

let selectionMenu =  RSSelectionMenu(selectionType: .Multiple, dataSource: customDataArray, cellType: .Custom(nibName: "CustomTableViewCell", cellIdentifier: "cell")) { (cell, person, indexPath) in

// cast cell to your custom cell type
let customCell = cell as! CustomTableViewCell

// set cell data here
}

Header Row - Empty, None, All, or Custom

// To show first row as Empty, when dropdown as no value selected by default
// Here you'll get Text and isSelected when user selects first row

selectionMenu.addFirstRowAs(rowType: .Empty, showSelected: self.firstRowSelected) { (text, isSelected) in
    
    // update your flag here to maintain consistency. -  This is required to be update when presenting for the second time.
    self.firstRowSelected = isSelected
}

DataSource - Codable Objects, NSObject Subclasses or Dictionary Array

• Implement UniqueProperty protocol to model class or structure.

class Person: NSObject, UniqueProperty {

    let id: Int
    let firstName: String
    let lastName: String

    init(id: Int, firstName: String, lastName: String) {
        self.id = id
        self.firstName = firstName
        self.lastName = lastName
    }

    // Here id has the unique value for each person
    func uniquePropertyName() -> String {
        return "id"
    }
}

or

struct Employee: Codable, UniqueProperty {
    
    let empId: Int?
    let name: String?
    
    func uniquePropertyName() -> String {
        return "empId"
    }
}

or

selectionMenu.uniquePropertyName = "empId" or "keyname of unique value in dictionary"

UI Customization

NavigationBar

• Set Title, BarButton Titles, TintColor, and Title Color

// set navigation title and color
selectionMenu.setNavigationBar(title: "Select Player", attributes: nil, barTintColor: UIColor.orange.withAlphaComponent(0.5), tintColor: UIColor.white)

// right barbutton title - Default is 'Done'
selectionMenu.rightBarButtonTitle = "Submit"

// left barbutton title - Default is 'Cancel'
selectionMenu.leftBarButtonTitle = "Close"

SearchBar

• Set Placeholder, Tint Color

// show searchbar with placeholder and tint color
selectionMenu.showSearchBar(withPlaceHolder: "Search Player", tintColor: UIColor.withAlphaComponent(0.5)) { (searchtext) -> ([String]) in
    return self.dataArray.filter({ $0.lowercased().hasPrefix(searchtext.lowercased()) })
}
