iPhone

iPad

Requirements

• iOS 8.0+
• Xcode 8.0+

Installation

CocoaPods

Yoshi is available through CocoaPods. To install it, simply add the following line to your Podfile:

Swift 4.2

pod 'Yoshi'

Swift 3.0

pod 'Yoshi', '2.2.2'

Swift 2.3

pod 'Yoshi', '1.1.1'

Subspec

Starting from version 3, Yoshi provides implementations for some common debugging tasks and category them in its subspecs, including:

• QAKit

To install, specify the subspec in your project's Podfile:

pod 'Yoshi', :subspecs => ['QAKit']

Carthage

You can also add Yoshi to your project using Carthage. Add the following to your Cartfile:

github "prolificinteractive/Yoshi"

Usage

To display Yoshi, simply set up the menu and present it.

// Setup the custom menus
Yoshi.setupDebugMenu([environmentMenu, instabugMenu, dateSelectionMenu])

// Invoke Yoshi
Yoshi.show()

By default, Yoshi will display your app's icon, along with the current build and version number.

Yoshi can be set up to display any sort of menu as long as the menu object conforms to YoshiGenericMenu. Action menu and single selection menus are available out of the box, with several easy-to-conform menu protocols providing flexibility to customize the cells.

Action Menu

Action Menu is the simplest Yoshi menu able to execute custom events when tapped.

For example, we can invoke Instabug when a custom menu is selected.

let instabugMenu = YoshiActionMenu(title: "Start Instabug",
                                   subtitle: nil,
                                   completion: { Instabug.invoke() })

Single Selection Menu

To display a single selection menu, just construct a YoshiSingleSelectionMenu with necessary information as below:

// Build necessary options.
let option1 = YoshiSingleSelection(title: "Option1", subtitle: "Select to push")
let option2 = YoshiSingleSelection(title: "Option2", subtitle: "Select to present")
let option3 = YoshiSingleSelection(title: "Option3", subtitle: "Select to dismiss")
let options: [YoshiTableViewMenuItem] = [option1, option2, option3]

// Construct YoshiSingleSelectionMenu.
let singleSelectionMenu = YoshiSingleSelectionMenu(title: "Options",
                                                   options: options,
                                                   selectedIndex: 0,
                                                   didSelect: { selection in /*Select the option based on selection*/ })

Yoshi will take care of managing selections and call back the convenient closure function when a new selection is made.

Date Selector Menu

To present a date selector menu, create a type that conforms to YoshiDateSelectorMenu protocol

final class DateSelectorMenu: YoshiDateSelectorMenu {

    var title: String
    var subtitle: String?
    var selectedDate: Date
    var didUpdateDate: (dateSelected: Date) -> ()

    init(title: String,
         subtitle: String? = nil,
         selectedDate: Date = Date(),
         didUpdateDate: (Date) -> ()) {
        self.title = title
        self.subtitle = subtitle
        self.selectedDate = selectedDate
        self.didUpdateDate = didUpdateDate
    }

}

let dateSelectorMenu = DateSelectorMenu(title: "Environment Date",
    subtitle: nil,
    didUpdateDate: { (dateSelected) in
      // Do something with the selected date here
})

Submenu

If you find your debug menu getting out of hand, you can organize it into submenus. To do so, just create a type that conforms to YoshiSubmenu:

final class Submenu: YoshiSubmenu {

    let title: String

    let subtitle: String?

    let options: [YoshiGenericMenu] {

}

let integrationsSubmenu = Submenu(title: "Third Party Integrations",
    subtitle: nil,
    options: [
        instabugMenu,
        crashlyticsMenu
    ]
)

Invocation Options

Yoshi can be invoked with a number of different options. The simplest way is to manually invoke using the show() function.

Yoshi.show()

In addition to the vanilla invocation option, Yoshi can also be invoked in response of 3 different options of motion or touch events.
If you want to enable all of those 3 following options you can simply pass the all option to the setupDebugMenu, although this option is already the default one.

Yoshi.setupDebugMenu([/* YoshiMenu items */], invocations: [.all])
/// Or simply
Yoshi.setupDebugMenu([/* YoshiMenu items */])

To specify which option you want exactly you just need to pass the ones you want to the setupDebugMenu function like this:

• To invoke Yoshi in response to a shake-motion gesture, add the shakeMotionGesture option in the setupDebugMenu invocations parameter as follows.

Yoshi.setupDebugMenu([/* YoshiMenu items */], invocations: [.shakeMotionGesture])

• To invoke Yoshi in in response to a multi-touch event, add the multiTouch option in the setupDebugMenu invocations parameter as follows.

Yoshi.setupDebugMenu([/* YoshiMenu items */], invocations: [.multiTouch])

• Finally, to invoke Yoshi in response to a 3D touch event, add the forceTouch option in the setupDebugMenu invocations parameter as follows.

Yoshi.setupDebugMenu([/* YoshiMenu items */], invocations: [.forceTouch])

Extra features

Clipboard copy

Long press on any cell of the Yoshi Menu to copy the subtitle.

Custom your cell UI

You can custom Yoshi menu cells using nib file or programmatically.
To do so, simply create a YoshiGenericMenu and a YoshiResuableCellDataSource:

To support custom UI, first, provide a YoshiResuableCellDataSource instance referencing to your custom cell.

• With Nib file

private final class CustomMenuCellDataSource: YoshiResuableCellDataSource {

    static var nib: UINib? {
        // Return your Nib file here
        return UINib(nibName: "CustomCell", bundle: nil)
    }

    func cellFor(tableView: UITableView) -> UITableViewCell {
    	// Dequeue and cast the cell here like you would normally did
        guard let cell = (tableView.dequeueReusableCell(withIdentifier: CustomMenuCellDataSource.reuseIdentifier)) as? CustomCell else {
            fatalError()
        }
        // config your cell here
        cell.label.text = "This is a custom cell"
        return cell
    }
}

• Without Nib file

private final class CustomMenuCellDataSource: YoshiResuableCellDataSource {

	func cellFor(tableView: UITableView) -> UITableViewCell {
    	// Dequeue the cell here like you would normally did, handle the case when deque failed
        guard let cell = (tableView.dequeueReusableCell(withIdentifier: CustomMenuCellDataSource.reuseIdentifier) ??
            UITableViewCell(style: .subtitle, reuseIdentifier: CustomMenuCellDataSource.reuseIdentifier)) as? CustomCell else {
                fatalError()
        }
        // config your cell here
        cell.label.text = "This is a custom cell"
        return cell
    }
}

Then, provide the menu that conforms to YoshiGenericMenu referencing to the data source.

struct MenuWithCustomUI: YoshiGenericMenu {

    var cellSource: YoshiResuableCellDataSource {
        return CustomMenuCellDataSource()
    }

    func execute() -> YoshiActionResult {
        // Do soomething here when the cell is tapped
        return .Handled
    }
}

Finally, display this custom menu like a normal Yoshi menu.

Yoshi.setupDebugMenu([MenuWithCustomUI()])
Yoshi.show()
