Xcode更新到5.1,"Cast from pointer to smaller type 'int' loses information” in EAGLView.mm

编译Cocos2dx时，在EAGLView.mm中

代码：

    for (UITouch *touch in touches) {

        ids[i] = (uintptr_t)touch;//(int)touch;//在这里int会出错，将其改为uintptr_t即可通过

        xs[i] = [touch locationInView: [touch view]].x * view.contentScaleFactor;;

        ys[i] = [touch locationInView: [touch view]].y * view.contentScaleFactor;;

        ++i;

    }
