Xamarin.forms导航栏标题设置IOS的文本颜色
我正在使用xamarin.forms应用程序,我想更改标题颜色。我添加了安卓系统,工作正常,但IOS系统不知道如何改变。我添加了状态栏设计Xamarin.forms导航栏标题设置IOS的文本颜色,xamarin.forms,xamarin.ios,navbar,Xamarin.forms,Xamarin.ios,Navbar,我正在使用xamarin.forms应用程序,我想更改标题颜色。我添加了安卓系统,工作正常,但IOS系统不知道如何改变。我添加了状态栏设计 public override void OnActivated(UIApplication uiApplication) { if (UIDevice.CurrentDevice.CheckSystemVersion(13, 0)) { //
public override void OnActivated(UIApplication uiApplication)
{
if (UIDevice.CurrentDevice.CheckSystemVersion(13, 0))
{
// If VS has updated to the latest version , you can use StatusBarManager , else use the first line code
// UIView statusBar = new UIView(UIApplication.SharedApplication.StatusBarFrame);
UIView statusBar = new UIView(UIApplication.SharedApplication.KeyWindow.WindowScene.StatusBarManager.StatusBarFrame);
statusBar.BackgroundColor = Color.FromHex("07987f").ToUIColor();
statusBar.TintColor= Color.FromHex("07987f").ToUIColor();
UIApplication.SharedApplication.KeyWindow.AddSubview(statusBar);
}
else
{
UIView statusBar = UIApplication.SharedApplication.ValueForKey(new NSString("statusBar")) as UIView;
if (statusBar.RespondsToSelector(new ObjCRuntime.Selector("setBackgroundColor:")))
{
statusBar.BackgroundColor = Color.FromHex("07987f").ToUIColor();
statusBar.TintColor= Color.FromHex("07987f").ToUIColor();
}
}
base.OnActivated(uiApplication);
}
状态栏、导航栏设计也可以:
UINavigationBar.Appearance.BarTintColor = Color.FromHex("07987f").ToUIColor();
UINavigationBar.Appearance.TintColor = Color.White.ToUIColor();
但是标题颜色是黑色。有什么建议吗?在这里TintColor属性更改导航栏的背景色 BarTintColor属性影响
- 后指示器图像
- 按钮标题
- 按钮图像
UINavigationBar.Appearance.TitleTextAttributes = new UIStringAttributes
{
ForegroundColor = UIColor.White
};
尝试设置
UINavigationBar.Appearance.TitleTextAttributes=newuistringattributes{ForegroundColor=UIColor.White}代码>@LucasZhang MSFT谢谢。我首先编写了UINavigationBar.Appearance.TitleTextAttributes.ForegroundColor=Color.White.ToUIColor();并获取NullObject异常。现在工作顺利了,我会把答案贴出来,你能接受吗?这将帮助更多人:)@LucasZhang MSFTyes@LucasZhang-微软接受
