GSTouchesShowingWindow

A simple tool that automatically shows all touches inside your app as they are happening, using a circular image indicator. It's useful for creating iOS 8 App Previews, or any kind of app videos where you need to demonstrate some rich user interaction that might be hard to explain otherwise.

Example

How to set it up

1. First, copy GSTouchesShowingWindow.h, GSTouchesShowingWindow.m and the GSTouchImage@2x.png to your project.

A. Now, if you are using Storyboard in your project (and you should), do the following. If you are not using Storyboard, skip this step and check 2.b.
In your AppDelegate.m, import the header:

#import “GSTouchesShowingWindow.h”

and add the following -window method. This will provide the app with our own window instance instead of the default UIWindow.

- (GSTouchesShowingWindow *)window {
    static GSTouchesShowingWindow *window = nil;
    if (!window) {
        window = [[GSTouchesShowingWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    }
    return window;
}

B. If you are still using plain old .xib files, you only need to open your MainWindow.xib, select the window and then change the class in Identity Inspector from UIWindow to GSTouchesShowingWindow. Like this:

3. That’s it! There is no step three.

How it actually works

Inside the UIWindow subclass, I am just overriding the -sendEvent method, processing all the events and adding/moving/removing imageViews based on those events' touches. And then I call [super sendEvent]; so that the touches are forwarded to the app.
