切换到另一个视图，但留在导航控制器

Question

我有一个关于特定产品的详细信息的导航控制器，其中一个细节是产品的小图像。现在我想添加一个按钮，该按钮必须通过产品的放大图像转到视图控制器。

如何使放大后的图像与细节屏幕位于同一导航控制器上，并且屏幕翻转过渡，但标题栏和标签栏不会翻转。

在导航控制器上添加了两个视图的概览图。

Answer 1

您可以使用类似：

UIView.Transition(this.NavigationController.View, 1f, 
UIViewAnimationOptions.CurveEaseInOut | UIViewAnimationOptions.TransitionFlipFromRight, 
delegate { this.NavigationController.PushViewController(this.ImageViewController, false); }); 

要使图片视图翻转的navogation控制器上时得到推而不是默认的过渡。 ImageViewController的title属性应该与您的详细信息中的属性相同。

UINavigationController的想法是处理多个控制器，因此您不应该通过覆盖视图来解决它。

Answer 2

将两个视图添加到控制器并为其帧属性设置动画以获得所需的效果。
