我正在尝试更改导航栏 Controller 和选项卡栏 Controller 的颜色
我正在使用 monotouch.dialog 来构建我的应用程序并具有以下代码
public partial class AppDelegate : UIApplicationDelegate
{
// class-level declarations
UIWindow window;
//
// This method is invoked when the application has loaded and is ready to run. In this
// method you should instantiate the window, load the UI into it and then make the window
// visible.
//
// You have 17 seconds to return from this method, or iOS will terminate your application.
//
public override bool FinishedLaunching (UIApplication app, NSDictionary options)
{
// create a new window instance based on the screen size
window = new UIWindow (UIScreen.MainScreen.Bounds);
// If you have defined a view, add it here:
// window.AddSubview (navigationController.View);
CreateTabs();
// make the window visible
window.MakeKeyAndVisible ();
return true;
}
protected void CreateTabs()
{
window = new UIWindow (UIScreen.MainScreen.Bounds);
var nav = new UITabBarController ();
nav.ViewControllers = new UIViewController [] {
new HomeController("Home"),
new WhereToUseController(),
new TransactionsController(),
new SettingsController()
};
// nav.TabBarController.TabBar.BackgroundColor = UIColor.Green;
nav.CustomizableViewControllers = new UIViewController [0];
window.RootViewController = nav;
// window.BackgroundColor = UIColor.Orange;
window.MakeKeyAndVisible ();
}
我的一个 Controller 的示例
public override void LoadView ()
{
base.LoadView ();
//TableView.BackgroundColor = UIColor.Clear;
// ParentViewController.View.BackgroundColor = UIColor.Red;
}
public HomeController (string s)
{
TabBarItem = new UITabBarItem (s, null, 1);
var root = new RootElement (s) {
new Section () {
new UIViewElement("My Caption:", view, false),
new StyledStringElement("Hello","somevalue"),
new StringElement ("Welcome back Shane"),
new ImageElement(new UIImage("Images/QR.png")),
}
};
PushViewController (new DialogViewController (root), false);
}
我应该在哪里改变颜色?让我改变顶部和底部?
最佳答案
如果您的目标是 iOS 5(及更新版本),那么您应该查看新的 UIAppearance
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)。
例如调用这个
UINavigationBar.Appearance.TintColor = UIColor.Black;
UITabBar.Appearance.TintColor = UIColor.Green;
来自您的FinishedLaunching
将使所有导航栏具有黑色背景,甚至是来自MonoTouch.Dialog的导航栏(而不是默认的蓝色)和具有绿色背景(而不是黑色)的选项卡栏。
注释 1: 在 iOS5 之前,您需要为每个控件设置 *Color
属性(这不太有趣,因为您并不总是有权访问它们)。
注释 2: 您创建了 UIWindow
的新实例两次,即在 FinishedLaunching
和 中调用以下内容创建选项卡
window = new UIWindow (UIScreen.MainScreen.Bounds);
