new StyledStringElement("Hello","somevalue"),
new StringElement ("Welcome back Shane"),
new ImageElement(new UIImage("Images/QR.png")),

PushViewController (new DialogViewController (root), false);
}
我应该在哪里换颜色?要允许我更改顶部和底部?如果您的目标是iOS 5(以及更新版本),那么您应该查看新的ui外观
功能。它将允许您为应用程序设置所有类型控件的外观(一次,而不是为您创建的每个控件)
打电话给这个
UINavigationBar.Appearance.TintColor = UIColor.Black;
UITabBar.Appearance.TintColor = UIColor.Green;
从您的FinishedLaunching
将使所有导航栏具有黑色背景,即使是来自MonoTouch.Dialog(而不是默认的蓝色)和选项卡栏的导航栏也具有绿色背景(而不是黑色)
注意1:在iOS5之前,您需要为每个控件设置*Color
属性(这不太有趣,因为您并不总能访问它们)
注意2:您两次创建了UIWindow的新实例,即在FinishedLaunching
和CreateTabs
window = new UIWindow (UIScreen.MainScreen.Bounds);
