问题描述
这是我的代码，仅未调用thumbnailImageForActivityType ...
class ShareMovieEvent: NSObject,UIActivityItemSource {
let movieDate: String
let movieTitle: String
let movieDescription: String
let imageHeader: UIImage
init(movieDate: String,movieTitle:String,movieDescription:String,imageHeader:UIImage) {
self.movieDate = movieDate
self.movieTitle = movieTitle
self.movieDescription = movieDescription
self.imageHeader = imageHeader
}
func activityViewControllerPlaceholderItem(_ activityViewController: UIActivityViewController) -> Any {
return ""
}
func activityViewController(_ activityViewController: UIActivityViewController,itemForActivityType activityType: UIActivity.ActivityType?) -> Any? {
if activityType == UIActivity.ActivityType.message {
return "\(movieDate) \n\n \(movieTitle) \n\n \(movieDescription)"
} else if activityType == UIActivity.ActivityType.mail {
return "\(movieDate) \n\n \(movieTitle) \n\n \(movieDescription)"
}
return nil
}
func activityViewController(_ activityViewController: UIActivityViewController,subjectForActivityType activityType: UIActivity.ActivityType?) -> String {
if activityType == UIActivity.ActivityType.message {
return ""
} else if activityType == UIActivity.ActivityType.mail {
return "Check this event"
}
return ""
}
func activityViewController(_ activityViewController: UIActivityViewController,thumbnailImageForActivityType activityType: UIActivity.ActivityType?,suggestedSize size: CGSize) -> UIImage? {
return imageHeader
}
}
这是我的ViewModel类中的调用
@objc func shareBtnPressed(_ sender: UIButton){
let share = ShareMovieEvent(movieDate: movie.date,movieTitle: movie.title,movieDescription: movie.movieDescription,imageHeader: imageHeaderMovie.image!)
let viewController = UIActivityViewController(activityItems: [share],applicationActivities: [])
self.pushableViewControllerObservable?(viewController)
}
