I m 自动交换机,其中含有UIImage电文。 因此,当其中一人被重新使用时,我必须做的第一项事情就是清楚它所展示的旧形象。 我似乎无法做到这一点。 我目前的法典是:
[self.imageView removeFromSuperview];
self.imageView = nil;
然后,Im 重新分发/加入。 UIImageView
,UIImage
等。 这似乎只是trick。 旧形象出现后,新形象出现在顶端。 我还需要做些什么来消除旧的形象?
感谢。

如果你重新处理你的UIImageView的话,你就重新找回了你的看法,因为你只是重新找回这些观点。
当你重新编辑《普通评论》时,确保放弃《普通评论》中的财产,即你在《普通评论》中处于循环状态时,不保留“UIImage”。
当你把电离层电离层电离层电离层外再使用时,图像应当被清除,你可以用新的图像数据重新绘制UIImageView的<>mage财产。 你们应当看到新的形象。
