- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
(我为这篇长文章道歉)为了让我的 AQGridView 更有趣,附加的代码将选定的单元格复制到 UIView 中,然后将该 View 设置为动画以扩展以填充屏幕,然后将 View 转换为看起来像全屏封面动画。随意重用,但这不是我的问题。我的问题是 Landscape 的动画,它必须不同。我希望将我的单元格 View 动画化到屏幕的右半部分并扩展以填充屏幕的右半部分(已经完成),然后让它在屏幕上向左旋转 y 翻转。 anchor 在 CGPointMake(0.5, 0.5);不起作用,也没有将平移 x 值设置为屏幕的一半并再次返回,它只是执行,然后飞出屏幕!帮助!!
编辑:(由于我没有意识到我已经将新的 UIView's
