我正在寻找有关在 iPhone 上创建幻灯片 ON/OFF 开关的 WPF 教程。
这是一个示例(“发送所有流量”选项)https://secure-tunnel.com/support/software_setup/iphone/images/iphone_vpn_settings.jpg

我还没有看到关于这个确切问题的教程,但我想你可以从启动 Expression Blend 并在其上放置一个 CheckBox 开始。然后选择复选框,进入主菜单 - 对象 -> 编辑样式 -> 编辑副本
这将使 Blend 生成 CheckBox 的默认样式,因此您可以对其进行修改。看看那里的事情是如何运作的,你将能够取得一些成果。
基本上(除了颜色和画笔),您需要查看与 IsChecked 属性挂钩的触发器。例如,当 IsChecked 为 True 时,您将矩形移动到一侧,显示 ON 字并隐藏 OFF 字。要对此进行动画处理,您只需添加触发器输入和输出动画。
UPD:我花了 10-15 分钟来混合制作“原型”:

如果您有兴趣,我还建议您阅读 WPF 中的样式和模板。
我根据 arcaut 的帖子创建了一些橙色和蓝色的样式。
截屏:
我希望我的风格更接近 iOS 设备的 On/Off Switch 风格。这种风格的一个区别是,滑动动画只滑动开关而不是下面的指示器。也许如果我能找到一些时间,我会这样修改它。在那之前,我想分享我的结果。它并不完美,但这是代码。

一些开源的切换开关:
我刚刚发布了一个关于此的条目,它提供了适当的滑动动作、完全可配置性并且不需要固定大小(因为我在网上找不到任何提供类似解决方案的东西而感到恼火)。
你可以在这里找到它:http: //itsallaboutthexaml.blogspot.com/2012/01/variables-in-animation.html
知道回答这个问题已经很晚了,但希望它对未来的任何人都有帮助。
我喜欢arconaut的漂亮原型,我添加了一些代码来使边框变圆。
您必须从 Grid 声明中删除“Background”属性,并在 Grid 声明和第一个 TextBlock 声明之间添加以下行:
<Border
x:Name="back"
CornerRadius="3,3,3,3"
BorderThickness="1"
BorderBrush="#FFC0CCD9"
>
<Rectangle Fill="#FFC0CCD9"/>
</Border>
好吧,我开始着手完成同样的任务,但这些示例与生产代码相比有点不足。例如,如果您将文本放入控件(如 On/Off 或文本的本地化版本)会发生什么情况,答案是您必须定义控件的大小,因为在呈现控件后您无法修改动画或模板触发器。这为您提供了一种万能的解决方案,该解决方案不适用于本地化文本。
我的解决方案是使用控件的 Loaded 事件和 FrameworkElementFactory 类为控件动态创建模板。我不得不说这很复杂,但可以实现。简单地说,在您的代码中,按照描述创建一个模板,为您的开/关文本设置依赖属性,使用文本度量来确定控件的宽度、高度和动画值。
很抱歉,我无法发布解决方案,因为它现在属于 Avanquest。:(
在 SystemSuite 和 Fix-It 12 中查找它。
