Ios 视图转换在自定义pop segue期间不设置动画
当我将新的视图控制器推到导航堆栈上时,我正在使用自定义序列创建扩展动画。如果在调用prepareForSegue:sender:时未指定sourceRect,则目标视图控制器将从源视图控制器的中心展开 ExpandSegue.m: expand segue按预期工作。我试图通过反转扩展序列的逻辑来创建一个折叠序列,但这给了我一些问题。我希望源代码视图控制器缩小到destinationRect的大小。如果未提供destinationRect,则我希望视图收缩到目标视图控制器视图的中心 CollapseSegue.m: sourceViewController的视图没有很好地设置动画,而是简单地消失,就好像我只调用了[sourceViewController.navigationController popViewControllerAnimated:NO];这似乎表明我没有正确设置视图层次结构,但我似乎无法找出哪里出了问题!任何帮助都将不胜感激Ios 视图转换在自定义pop segue期间不设置动画,ios,uistoryboardsegue,Ios,Uistoryboardsegue,当我将新的视图控制器推到导航堆栈上时,我正在使用自定义序列创建扩展动画。如果在调用prepareForSegue:sender:时未指定sourceRect,则目标视图控制器将从源视图控制器的中心展开 ExpandSegue.m: expand segue按预期工作。我试图通过反转扩展序列的逻辑来创建一个折叠序列,但这给了我一些问题。我希望源代码视图控制器缩小到destinationRect的大小。如果未提供destinationRect,则我希望视图收缩到目标视图控制器视图的中心 Collap
