這closedCaptionButton被聲明為BCOVPUIButton , 這是一個子類UIButton並添加了三種額外的自定義方法。每當您自定義BCOVPlayerUI控件時，都應在可用的地方使用Native Player API。您的自定義代碼應類似於以下內容：
// Customize the CC button.
BCOVPUIButton *ccButton = playerView.controlsView.closedCaptionButton;
ccButton.titleLabel.font = [UIFont systemFontOfSize:14.];
ccButton.primaryTitle = @"CC";
[ccButton showPrimaryTitle:YES];
if let ccButton = playerView.controlsView.closedCaptionButton {
ccButton.titleLabel?.font = UIFont.systemFont(ofSize: 14)
ccButton.primaryTitle = "CC"
ccButton.showPrimaryTitle(true)}
