对与cocos2d-x3.x 版本中的plist 文件中的frame 中的二维数组的

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>frames</key>
        <dict>
            <key>BG1.png</key>
            <dict>
                <key>frame</key>
                <string>{{0,0},{960,640}}</string>
                <key>offset</key>
                <string>{0,0}</string>
                <key>rotated</key>
                <false/>
                <key>sourceColorRect</key>
                <string>{{0,640}}</string>

        <dict>
            <key>format</key>
            <integer>2</integer>
            <key>realTextureFileName</key>
            <string>BG1-hd.pvr.ccz</string>
            <key>size</key>

            <string>BG1-hd.pvr.ccz</string>
        </dict>
    </dict>
</plist>

中<key>frame</key>                <string>{{0,640}}</string>                <key>offset</key>

的二维数组读取其实是用到的COCOS2D-x中的Rect 结构

<pre class="cpp" name="code">Rect rect;
	rect=<span style="color:#ff6666;">RectFromString</span>(farscene->valueForKey("frame")->getCString());

	
//	Point point=PointFromString()
	log("point=%f,%f,%f",rect.origin.x,rect.origin.y,rect.size.width,rect.size.height);

该类型相同的函有三个，<span style="color:#3333ff;">PointFromString(),RectFromString(),SizeFromString();这是我今天的收获。</span>
