首先介绍一个api和相应的参数：
cc.view.setDesignResolutionSize(1024, 768, cc.ResolutionPolicy.FIXED_WIDTH);
这里设置游戏制作的目标尺寸和显示的模式。
模式包括：
cc.ResolutionPolicy = {
// The entire application is visible in the specified area without trying to preserve the original aspect ratio.
// Distortion can occur, and the application may appear stretched or compressed.
EXACT_FIT:0,
// The entire application fills the specified area, without distortion but possibly with some cropping,
// while maintaining the original aspect ratio of the application.
NO_BORDER:1,
// The entire application is visible in the specified area without distortion while maintaining the original
// aspect ratio of the application. Borders can appear on two sides of the application.
SHOW_ALL:2,
// The application takes the height of the design resolution size and modifies the width of the internal
// canvas so that it fits the aspect ratio of the device
// no distortion will occur however you must make sure your application works on different
// aspect ratios
FIXED_HEIGHT:3,
// The application takes the width of the design resolution size and modifies the height of the internal
// canvas so that it fits the aspect ratio of the device
// no distortion will occur however you must make sure your application works on different
// aspect ratios
FIXED_WIDTH:4,
UNKNOWN:5
};
参考官方说明： http://www.cocos2d-x.org/wiki/Multi_resolution_support
EXACT_FIT会拉伸游戏，充满整个屏幕，最简单最粗暴；
SHOW_ALL保持游戏原比例，让一边占满屏幕，另外一侧黑边；
NO_BORDER跟SHOW_ALL类似，但让短边占满屏幕，另外一侧超出屏幕，不显示黑边，一部分画面在屏幕外，无法显示；
FIXED_WIDTH和FIXED_HEIGHT都是NO_BORDER的升级版，指定那一侧充满屏幕，另外一侧超出屏幕。
这里建议使用FIXED_WIDTH和FIXED_HEIGHT，其他用法请参考：
