신속한 mp3 파일 공유 3

Question

콜렉션 뷰 셀에서 길게 누르면 mp3 파일을 공유하고 싶습니다. 나는 아래 코드를 썼다. 그러나 그것은 아무 것도 반환하지 않는다. 내 자신에게 전자 메일을 보냈을 때 말입니다. 그것은 mp3 파일을 포함하지 않으며 또한 whatsapp 부분을 볼 수 없습니다.

let r = NSURL(fileURLWithPath: temp_url!) 
    //var activityItems: [Any] = [temp_url!] 
    let activityViewController = UIActivityViewController(activityItems: [r], applicationActivities: nil) 
    activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash 

    // exclude some activity types from the list (optional) 
    let excludeActivities = [UIActivityType.airDrop, UIActivityType.print, UIActivityType.assignToContact, UIActivityType.saveToCameraRoll, UIActivityType.addToReadingList, UIActivityType.postToFlickr, UIActivityType.postToVimeo, UIActivityType.postToFacebook, UIActivityType.message, UIActivityType.postToWeibo] 
    activityViewController.excludedActivityTypes = excludeActivities 

    // present the view controller 
    self.present(activityViewController, animated: true, completion: nil) 


    // exclude some activity types from the list (optional) 
    activityViewController.excludedActivityTypes = [ UIActivityType.airDrop, UIActivityType.postToFacebook ] 

    // present the view controller 
    self.present(activityViewController, animated: true, completion: nil)

아래 코드로 해결합니다.

if(temp_url != nil){ 
let activityViewController = UIActivityViewController(activityItems: [temp_url!], applicationActivities: nil) 
     activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash 

     // exclude some activity types from the list (optional) 
     let excludeActivities = [UIActivityType.airDrop, UIActivityType.print, UIActivityType.assignToContact, UIActivityType.saveToCameraRoll, UIActivityType.addToReadingList, UIActivityType.postToFlickr, UIActivityType.postToVimeo, UIActivityType.postToFacebook, UIActivityType.message, UIActivityType.postToWeibo] 
     activityViewController.excludedActivityTypes = excludeActivities 

     // present the view controller 
     self.present(activityViewController, animated: true, completion: nil) 
}
