我与C4一道玩.,似乎无法说明我的形状为何不行。 如果我这样作的话:
self.theShape = [C4Shape ellipse:CGRectMake(100, 100, 2, 2)];
页: 1
[theShape setFrame:CGRectMake(200, 200, 50,50)];
形形形形形形形形形形形形色色色的大小变化。 执行表明,它应当,但我看不到。 是否有人错了吗? 这是否是因为我没有更新信道?

在C4中,在C4Shape物体上打上setFrame:
将不予以扩大。
原因是,改变化学文摘社协会的观点框架不会改变其基本面貌。 与此不同的是,在形象上用同样的东西。 UI 工具包将扩大图像和其他内容,但不会扩大用户(如我所知)。
因此,如果要求撤销,则要求:
[theShape rect:aNewFrame]
或者,如果说是粗略的,则要求:
[theShape ellipse:aNewFrame]
这种做法形成了一种新的形态,然后是杠杆作用。 核心分析能力,可以含蓄地将旧形线与新方向之间的过渡联系起来。
