#GridOverlay

This swift class will overlay a grid over your UI to help make sure UI elements align to redlines.

Installation:

Copy the GridOverlay.swift class to your project

Usage:

In code:

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
        GridOverlay.gridColor = UIColor.redColor()
        GridOverlay.gridSize = CGSizeMake(30, 30)
        GridOverlay.show()
    }

In the debugger:

You can also show, hide, or configure the GridOverlay at runtime but setting a breakpoint and executing the commands in the debugger.

expr GridOverlay.show()

You will need to let the app process the main thread's runloop so the UI can be updated after executing the command in the debugger.

Note: you may need to import UIKit in the debugger session to use UIColor, etc

expr @import UIKit
