A grid overlay for iOS apps.
Use this during the development of your app to help align your interface to a grid, and easily spot layout issues. It will overlay every view in your app, but not interfere with interaction, so you can still move around.
A simple example app is included.
SUPGridWindow *grid = [SUPGridWindow sharedGridWindow]; [grid setGridColor:[UIColor redColor]]; [grid setMajorGridSize:CGSizeMake(40, 40)]; [grid setMinorGridSize:CGSizeMake(10, 10)];
This is a development tool. You probably want to make sure you don't ship with this. The window is added above all others, so it will even overlay the keyboard and the status bar. Apple doesn't like that.
The right gesture to toggle the grid will vary app to app, so we didn't set any by default.
