我正在尝试向其中一个UICollectionViewCell添加一些按钮或标签,但当点击共享按钮时,似乎无法激活UIActivityViewController。
以下是我的代码:
class VerticalCollectionViewCell: UICollectionViewCell {
override init(frame: CGRect) {
super.init(frame: frame)
containerView.addSubview(shareButton)
shareButton.bottomAnchor.constraint(equalTo: containerView.bottomAnchor, constant: -16).isActive = true
shareButton.rightAnchor.constraint(equalTo: favoriteButton.leftAnchor, constant: -16).isActive = true
shareButton.widthAnchor.constraint(equalToConstant: 24).isActive = true
shareButton.heightAnchor.constraint(equalToConstant: 24).isActive = true
shareButton.addTarget(self, action: #selector(handleShareButton), for: .touchUpInside)
}
@objc func handleShareButton(sender: UIButton) {
let shareText = NSLocalizedString("I found something interesting you may want to take a look at.", comment: "share")
let shareImage = #imageLiteral(resourceName: "Bear")
let activityViewController : UIActivityViewController = UIActivityViewController(activityItems: [shareText, shareImage as Any], applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView = self.view
self.present(activityViewController, animated: true, completion: nil)
}
}
错误包括:
Value of type 'VerticalCollectionViewCell' has no member 'view'
和
Value of type 'VerticalCollectionViewCell' has no member 'present'
.
我知道presentViewController是一个UIViewController方法,UITableViewCell没有名为presentViewController的方法,UITableViewCell不应该处理任何业务逻辑。它应该在视图控制器中实现。
但我不知道如何解决这个问题。
