excludeActivityTypes 在 Swift 3 中不起作用

Question

我正在开发我的图像 iOS 应用程序，我刚刚添加了一个图像共享按钮，我希望排除共享类型的一些功能，但是当我在模拟器中运行时，所有功能都在那里。

这是我的代码...

let image = UIImage("b3")
let imageToShare = [image!]
let shareImage =  UIActivityViewController (activity items:imageToShare,application Activities:nil)
shareImage.popoverPresentationController?.sourceView = self.view
self.present (shareImage,animated:true,completion:nil)
shareImage.excludedActivityTypes = [UIActivityType.print,UIActivityType. copyToPasteboard]

如何排除它们？ 请提供任何建议

Answer 1

只要改变顺序excludedActivityTypes上UIActivityViewController

像这样：

shareImage.excludedActivityTypes = [UIActivityType.print,UIActivityType.copyToPasteboard]
self.present (shareImage,animated:true,completion:nil)

Answer 2

您在设置 excludeActivityTypes 之前展示您的活动视图控制器。 用以下代码替换您的代码：

let image = UIImage("b3")
let imageToShare = [image!]
let shareImage = UIActivityViewController (activity items:imageToShare,application Activities:nil)
shareImage.popoverPresentationController?.sourceView = self.view
shareImage.excludedActivityTypes = [UIActivityType.print, UIActivityType.copyToPasteboard]
self.present (shareImage, animated:true, completion:nil)
