This is a frequently asked question. Multi-touch feature is available on both iOS & Android port since the first version of cocos2d-x. But in iOS, apple turns the switcher off by default, and offers an API to enable it manually.

iOS

Please refer to cocos2d-x/samples/Cpp/TestCpp/proj.ios/Classes/testAppDelegate.mm, line 39

[__glView setMultipleTouchEnabled:YES]

When you have a project created by xcode cocos2d-x templates, you can modify this file MyGame/proj.ios/AppController.mm as below

1- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

2

// Override point for customization after application launch.

4

// Add the view controller's view to the window and display.

6 window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];

7 EAGLView *__glView = [EAGLView viewWithFrame: [window bounds]

8 pixelFormat: kEAGLColorFormatRGBA8

9 depthFormat: GL_DEPTH_COMPONENT16_OES

10 preserveBackbuffer: NO

11 sharegroup: nil

12 multiSampling: NO

13 numberOfSamples: ];

14

[__glView setMultipleTouchEnabled:YES]; // enable multi-touch here!! It's at about line 37

16

17 // ...

18

19 return YES;

20}

Apple official document about setMultipleTouchEnabled is HERE:

Android

On android, the multi-touch is open by default. You don't need to open anything before get the touch coordinates in void MyLayer::ccTouchesBegan/Moved/Ended

Other platforms

People usually debug cocos2d-x games on windows desktop system. But sadly, there's no multi-touch support on windows. You had to connect your mobile phones and test multi-touch feature on them.

Multi-touch Test Case

We added a test case for multi-touch since v2.0. After launching TestCpp, you can enter this test case from "MultiTouchTest". The video looks like this
