我想排除微博和微信，并设置以下代码：

let av = UIActivityViewController(activityItems: items, applicationActivities:nil)
av.excludedActivityTypes = [.postToWeibo, .postToTencentWeibo]
self.present(av, animated: true)

无论我做了什么，这两个应用程序仍然显示在UIActivityViewController上。但不包括邮件和copyToPasteboard都是可行的

av.excludedActivityTypes = [.postToWeibo, .postToTencentWeibo, .copyToPasteboard, .mail]
