Only a demo

Share.share({
                message:'MSG',
                url:'URL',
                title:'RN',
            },{
                 dialogTitle:'Stephanie',
                 excludedActivityTypes:[
                    //把你不想要展示的内容同通过放在这里
                    //这里仅仅展示一个;其他的自己添加;我在下面给出其他选项
                    'com.apple.UIKit'.activity.PostToFacebook
                ],
                  tintColor:'green'
            }).then(this._showResult).catch(error) => this.setState({result:'error:' + error.message});

extension UIActivity.ActivityType {

    @available(iOS 6.0, *)
    public static let postToFacebook: UIActivity.ActivityType

    @available(iOS 6.0, *)
    public static let postToTwitter: UIActivity.ActivityType

    @available(iOS 6.0, *)
    public static let postToWeibo: UIActivity.ActivityType

    @available(iOS 6.0, *)
    public static let message: UIActivity.ActivityType

    @available(iOS 6.0, *)
    public static let mail: UIActivity.ActivityType

    @available(iOS 6.0, *)
    public static let print: UIActivity.ActivityType

    @available(iOS 6.0, *)
    public static let copyToPasteboard: UIActivity.ActivityType

    @available(iOS 6.0, *)
    public static let assignToContact: UIActivity.ActivityType

    @available(iOS 6.0, *)
    public static let saveToCameraRoll: UIActivity.ActivityType

    @available(iOS 7.0, *)
    public static let addToReadingList: UIActivity.ActivityType

    @available(iOS 7.0, *)
    public static let postToFlickr: UIActivity.ActivityType

    @available(iOS 7.0, *)
    public static let postToVimeo: UIActivity.ActivityType

    @available(iOS 7.0, *)
    public static let postToTencentWeibo: UIActivity.ActivityType

    @available(iOS 7.0, *)
    public static let airDrop: UIActivity.ActivityType

    @available(iOS 9.0, *)
    public static let openInIBooks: UIActivity.ActivityType

    @available(iOS 11.0, *)
    public static let markupAsPDF: UIActivity.ActivityType
}

如果使用其他组件应该也会有类似excludedActivityTypes的字段,道理是一样的
