Question

我已经审核了GoogleCast v3 SDK中提供的自定义样式，除非我遗漏了一些内容，否则我看不到更改deviceChooser的backgroundColor的方法。见下文：

有没有办法改变这种灰色？

Answer 1

Google Cast sdk使用的是常规UINavigationBar。在推送到sdk的媒体控件UI之前，您可以更改导航栏的外观。

我尝试过didFinishLaunchingWithOptions

 [UINavigationBar appearance].barTintColor = [UIColor whiteColor];
 [UINavigationBar appearance].translucent = NO;

希望它会有所帮助:)

Answer 2

您可以通过以下多种方式在适用于 iOS 的 Chromecast SDK 上自定义样式：

GCKUIStyle.sharedInstance()

我对导航栏样式的贡献：

从DOCUMENTATION我可以看到下图

所有“样式类”之间的共同点是它们都继承自 GCKUIStyleAttributes 所以：

func configureChromecast() {
    let gckCriteria = GCKDiscoveryCriteria(applicationID: "ABC123")
    let gckCastOptions = GCKCastOptions(discoveryCriteria: gckCriteria)
    
    GCKCastContext.setSharedInstanceWith(gckCastOptions)
    GCKLogger.sharedInstance().delegate = self
    
    // General
    let textColor: UIColor = UIColor.black
    let backgroundColor: UIColor = UIColor.white
    
    GCKUIStyle.sharedInstance().castViews.backgroundColor = backgroundColor
    
    GCKUIStyle.sharedInstance().castViews.headingTextColor = textColor
    GCKUIStyle.sharedInstance().castViews.headingTextFont = UIFont.textStyleRegular
    
    GCKUIStyle.sharedInstance().castViews.bodyTextColor = textColor
    GCKUIStyle.sharedInstance().castViews.bodyTextFont = UIFont.textStyleRegular
    
    GCKUIStyle.sharedInstance().castViews.captionTextColor = textColor
    GCKUIStyle.sharedInstance().castViews.captionTextFont = UIFont.textStyleRegular
    
    GCKUIStyle.sharedInstance().castViews.buttonTextColor = textColor
    GCKUIStyle.sharedInstance().castViews.buttonTextFont = UIFont.textStyleRegular
    
    GCKUIStyle.sharedInstance().castViews.iconTintColor = textColor
    
    
    // Navigation & Toolbar
    let navigationBackgroundColor: UIColor = UIColor.blue
    let navigationtintColor: UIColor = UIColor.white
    
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.navigation.backgroundColor = navigationBackgroundColor
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.toolbar.backgroundColor = navigationBackgroundColor
    
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.navigation.headingTextColor = navigationtintColor
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.toolbar.headingTextColor = navigationtintColor
    
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.navigation.bodyTextColor = navigationtintColor
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.toolbar.bodyTextColor = navigationtintColor
    
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.navigation.captionTextColor = navigationtintColor
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.toolbar.captionTextColor = navigationtintColor
    
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.navigation.buttonTextColor = navigationtintColor
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.toolbar.buttonTextColor = navigationtintColor
    
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.navigation.iconTintColor = navigationtintColor
    GCKUIStyle.sharedInstance().castViews.deviceControl.connectionController.toolbar.iconTintColor = navigationtintColor
    
    
    GCKUIStyle.sharedInstance().apply()
}

结果：

Answer 3

您可以使用GCKUIStyle设置所有GCK视图的样式，

例如：

GCKUIStyle.sharedInstance().castViews.mediaControl.miniController.buttonTextColor = .black

GCKUIStyle.sharedInstance().apply()

根据您的情况，可以使用此行设置导航样式

connectionController.navigation.backgroundColor = UIColor.black

我可以更改Chromecast导航栏的背景颜色吗？
