我正在寻找一个关于在iPhone上创建幻灯片ON / OFF开关的WPF教程。
以下是一个示例(“发送所有流量”选项)https://secure-tunnel.com/support/software_setup/iphone/images/iphone_vpn_settings.jpg
有什么想法吗?
干杯, 凯文。

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CheckBox开始。然后选择CheckBox,转到主菜单 - 对象 - >编辑样式 - >编辑副本
这将使Blend生成CheckBox的默认样式,以便您能够修改它。看看事情是如何运作的,你将能够取得一些成果。
基本上(除了颜色和画笔之外)你需要查看连接到IsChecked属性的触发器。 例如。当IsChecked为True时,您将矩形移动到其中一个边,显示ON字并隐藏OFF字。要为此设置动画,您只需添加触发动画内外动画。
UPD: 我花了10-15分钟时间混合制作一个“原型”:

我根据arconaut的橙色和蓝色创建了一些样式。

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,滑动动画只会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,我会以这种方式修改它。在那之前,我想分享我的结果。它并不完美,但这是代码。

我刚刚发布了一个关于此的条目,该条目提供了正确的滑动动作,完全可配置性并且不需要是固定大小(因为我在Web上找不到任何提供类似解决方案的内容而感到烦恼)。
您可以在此处找到它:http://itsallaboutthexaml.blogspot.com/2012/01/variables-in-animation.html
知道回答这个问题已经很晚了,但希望将来能帮到任何人。
答案 4 :(得分:1)
我开始着手完成同样的任务,但是这些例子略微缺乏生产代码。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,因为在渲染控件后无法修改动画或模板触发器。这为您提供了一种适用于本地化文本的“一刀切”的解决方案。
我的解决方案是使用控件的Loaded事件和FrameworkElementFactory类动态创建控件的模板。我不得不说这是复杂的,但可以实现。简单地说,在你的代码中,按照描述创建一个模板,设置开/关文本的依赖属性,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。 :(

答案 5 :(得分:0)
我喜欢arconaut的优秀原型,并添加了一些代码以使边框四舍五入。
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>
