c# - MvvmCross - 如何添加自定义模态转换
<p><p>我正在使用 MvvmCross 和 Xamarin 开发一个项目。我试图在呈现和关闭我的模态视图时添加自定义过渡。目前我是这样介绍的:</p>
<pre><code>
public partial class MyView : MvxViewController
{
</code></pre>
<p>并以这种方式解雇它:</p>
<pre><code>NavigationController.DismissModalViewController(true);
</code></pre>
<p>所以我已经准备好我的动画，但我假设我需要将转换委托(delegate)设置为我创建的那个。我该怎么做？</p>
<p>我对 MvvmCross 还很陌生，因此非常感谢任何提示和技巧。谢谢!</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我不确定，你真正想要在这里实现什么。</p>
<p>如果您正在寻找语法帮助。应该是这样的。</p>
<pre><code>this.NavigationController.TransitioningDelegate = new MyOwnDelegate();
internal class MyOwnDelegate : IUIViewControllerTransitioningDelegate
{
public IntPtr Handle => throw new NotImplementedException();
public void Dispose()
{
//throw new NotImplementedException();
}
}
</code></pre>
<p>但通常人们使用，这个。如果有帮助，我也会给出一些语法</p>
<pre><code>this.NavigationController.Delegate = new NavigationControllerDelegate();
public class NavigationControllerDelegate : UINavigationControllerDelegate
{
public NavigationControllerDelegate(IntPtr handle) : base(handle)
{
}
public NavigationControllerDelegate()
{
}
public override IUIViewControllerAnimatedTransitioning GetAnimationControllerForOperation(UINavigationController navigationController, UINavigationControllerOperation operation, UIViewController fromViewController, UIViewController toViewController)
{
var fromVcConformA = fromViewController as ICustomTransition;
var fromVCConFromB = fromViewController as IWaterFallViewControllerProtocol;
var fromVCCConformc = fromViewController as IHorizontalPageViewControllerProtocol;
var toVcConformA = toViewController as ICustomTransition;
var toVCConfromB = toViewController as IWaterFallViewControllerProtocol;
var toVCCConformc = toViewController as IHorizontalPageViewControllerProtocol;
if ((fromVcConformA != null) && (toVcConformA != null) && ((fromVCConFromB != null && toVCCConformc != null) || (fromVCCConformc != null && toVCConfromB != null)))
{
var transition = new CustomTransition();
transition.presenting = operation == UINavigationControllerOperation.Pop;
return transition;
}
else
{
return null;
}
}
}
</code></pre></p>
