RadialMenu

Looking for help? For $150/hr I'll help with your RadialMenu problems including integrating it into your project. Email [email protected] to get started!

Experimental Software: Fun to play with, but probably shouldn't put it in production (yet).

RadialMenu is a custom control that allows you to provide a context menu to a user on a touch screen (generally after a long press). This is similar to the record functionality Apple introduced for iMessage in iOS 8.

Here's an example of the iMessage menu recreated, taken from the demo app:

You can create your own custom menus as well

Plus it's built with Facebook POP, so it's very flexible!

Install

Copy the source files from the RadialMenu/ directory into your project.

How to use?

There are two examples provided which show how to use the control in detail (download and run the Xcode project). At a highlevel:

// Create a radial submenu (it's just a UIView subclass)
let subMenuRed = RadialSubMenu(frame: frameOfSubMenu)
subMenuRed.userInteractionEnabled = true
subMenuRed.layer.cornerRadius = subMenuRadius
subMenuRed.layer.backgroundColor = UIColor.redColor()
subMenuRed.layer.borderColor = UIColor.blackColor()
subMenuRed.layer.borderWidth = 1
subMenuRed.tag = tag


// Create multiple submenus and assign to array
let subMenus = [subMenuRed, subMenuBlue, ...]


// Initialize the radial menu
let radialMenu = RadialMenu(menus: subMenus, radius: menuRadius)
radialMenu.center = view.center
radialMenu.openDelayStep = 0.05
radialMenu.closeDelayStep = 0.00
radialMenu.minAngle = 180
radialMenu.maxAngle = 360
radialMenu.activatedDelay = 1.0
radialMenu.backgroundView.alpha = 0.0

// Setup event handlers for specific actions
radialMenu.onOpen = {
    // menu has opened
}

radialMenu.onHighlight = { subMenu in
    // perform highlight change
}

radialMenu.onActivate = { subMenu in
    // did select subMenu
}


// Setup menu to show when pressing a button
let longPress = UILongPressGestureRecognizer(target: self, action: "pressedButton:")
button.addGestureRecognizer(longPress)

// Gesture handler can react to menu in different ways depending what you want
// (for example, keeping the menu open if nothing is selected)
func pressedButton(gesture:UIGestureRecognizer) {
    switch(gesture.state) {
        case .Began:
            radialMenu.openAtPosition(button.center)
        case .Ended:
            radialMenu.close()
        case .Changed:
            radialMenu.moveAtPosition(gesture.locationInView(self.view))
        default:
            break
    }
}
