Airdrop 可以從 UIActivityViewController 使用。UIActivityViewController 類是標準檢視控制器，提供多種標準服務，例如將專案複製到剪貼簿，將內容共享到社交媒體站點，通過 Messages，AirDrop 和一些第三方應用程式傳送專案。

在這種情況下，我們將通過 UIActivityViewController 傳送影象

UIImage *hatImage = [UIImage imageNamed:@"logo.png"];
if (hatImage)//checks if the image file is not nil
{
//Initialise a UIActivityViewController
UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:@[hatImage] applicationActivities:nil];
//Excludes following options from the UIActivityViewController menu
NSArray *excludeActivities = @[UIActivityTypePostToWeibo,UIActivityTypePrint, UIActivityTypeMail,UIActivityTypeMessage,UIActivityTypePostToTwitter,UIActivityTypePostToFacebook,
                                                              UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,
                                                              UIActivityTypeSaveToCameraRoll,UIActivityTypeAddToReadingList,
                                                              UIActivityTypePostToFlickr,UIActivityTypePostToVimeo,
                                                              UIActivityTypePostToTencentWeibo];
controller.excludedActivityTypes = excludeActivities;
[self presentViewController:controller animated:YES completion:nil];
}

迅速

if ((newImage) != nil)
        {
            let activityVC = UIActivityViewController(activityItems: [newImage], applicationActivities: nil)
            activityVC.excludedActivityTypes =[UIActivityTypeAddToReadingList]
            self.presentViewController(activityVC, animated: true, completion: nil)
            
        }
