use picture with size, equal to size of the screen(480x320 for non-retina iPhone/iPod, 960x640 for retina iPhone/iPod, 1024x768 for iPad, 2048x1536 for retina iPad). If you want to stretch picture to make it fill whole screen, change it's scaleXand scaleYproperties:
使用大小等于屏幕大小的图片（非视网膜 iPhone/iPod 为 480x320，视网膜 iPhone/iPod 为 960x640，iPad 为 1024x768，视网膜 iPad 为 2048x1536）。如果要拉伸图片以使其填满整个屏幕，请更改它的scaleX和scaleY属性：
CGSize winSize = [[CCDirector sharedDirector] winSize];
CGSize imageSize = image.contentSize;
imageSprite.scaleX = winSize.width / imageSize.width;
imageSprite.scaleY = winSize.height / imageSize.height;

To set the background for cocos2d 3.x
为 cocos2d 3.x 设置背景
CGSize wSize=[[CCDirector sharedDirector] viewSize];
CGSize scrSize={640,1136};
CCSprite* background1 = [CCSprite spriteWithFile:@"1136.png"];
background1.anchorPoint=ccp(0, 0);
background1.scaleX=wSize.width/scrSize.width;
background1.scaleY=wSize.height/scrSize.height;
[self addChild:background1];
