ImagePicker

The newest code can be found here: cocos2d/cocos2d-x#11344. I've put all the codes into cocos2d-x 3.5 along with tests. Also win8.1-universal is supported now.

ImagePicker utility for cocos2d-x 3.5

Attention

• iOS 8 may crash with default setting. Please check out this issue iPhone 5S Error here. I haven't found an elegant way to fix this, and any pull request is welcomed!

This utility lets you load images from device gallery and load it to your application as a Texture2D. You may draw Sprite with this texture or use it in other ways.

The origin project is https://github.com/Losiowaty/ImagePicker, and I clear the whole project, in addition to:

• add support for iPhone (combined with iPad)
• add support for Win32/OSX/Win8.1
• put Android support together
• take advantage of ccx 3.5 API
• Javascript Binding (lua binding to be done)
• return base64 image data (Mac/iOS/Android) by Zinitter

The image is loaded by platform API and deliveried to ccx in memory directly. No repeated IO is needed.

Guide

Installation

1. iOS/Mac

Add the following sources into project:

• ImagePicker.h, ImagePicker.cpp
• ImagePickerImpl.h, ImagePickerImpl.mm
• ImagePicker-ios.h, ImagePicker-ios.mm (iOS only)
• ImagePickerBase64-ios-mac.h, ImagePickerBase64-ios-mac.m

2. Android/Win32/Win8.1

• ImagePicker.h, ImagePicker.cpp
• ImagePickerImpl.h, ImagePickerImpl.cpp
• Cocos2dxImagePicker.java (Android only)
• Base64.java (Android only)
• App.xaml.cs (Win8.1 phone version only)

3. JSB

• jsb_cocos2dx_extension_ImagePicker.hpp
• jsb_cocos2dx_extension_ImagePicker.cpp

Usage

Just call ImagePicker::getInstance()->pickImage() and pass in your delegate. If the image is picked successfully, your delegate will receive the corresponding Texture2D, or nullptr otherwise.

For cocos2d-JS users: add sc->addRegisterCallback(register_all_cocos2dx_extension_ImagePicker); in AppDelegate.cpp,

var delegator = new jsb.ImagePickerDelegate();
delegator.didFinishPickingWithResult = function(texture, base64Data){
    if(texture) {
        var sprite = cc.Sprite.createWithTexture(texture);
        var winSize = cc.director.getWinSize();
        sprite.x = winSize.width / 2;
        sprite.y = winSize.height / 2;
        self.addChild(sprite);
    }
    else {
        cc.log("ImagePicker return null");
    }
};
var picker = jsb.ImagePicker.getInstance();
picker.pickImage(delegator);
