ios - 空投:使自定义 URL 方案对收件人来说不那么难看

Question

我正在使用 Airdrop 发送自定义 URL，使我的应用在其他设备上打开并显示相关信息。

它工作正常，但在接收设备上看起来真的很难看，因为他们收到一条消息，其中引用了正在发送的 URL，例如 schemename://123456。有什么方法可以使消息看起来更好，或者让接收设备告诉您它想在哪个应用程序中打开信息，而不是显示神秘的 URL？

制作一个与 UIActivityItemSource 确认的自定义对象

 @interface LAAirDropCustomUrl : NSObject <UIActivityItemSource>

 @property (strong, nonatomic) NSURL *url;
 @property (strong, nonatomic) UIImage *productImage;
 - (id)initWithUrl:(NSURL *)url;


 @end



  @implementation LAAirDropCustomUrl

  - (id)initWithUrl:(NSURL *)url {
      if (self = [super init]) {
          _url = url;
      }
      return self;
  }

  #pragma mark - UIActivityItemSource

  - (id)activityViewControllerPlaceholderItem:(UIActivityViewController *)activityViewController {
      //Because the URL is already set it can be the placeholder. The API will use this to determine that an object of class type NSURL will be sent.
      return self.url;
  }

  - (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType {
      //Return the URL being used. This URL has a custom scheme (see ReadMe.txt and Info.plist for more information about registering a custom URL scheme).
      if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
          return nil;
      } else {
          if ([activityType isEqualToString:UIActivityTypeAirDrop]) {
              return self.url;
          }
      }
      return  nil;
  }

  - (UIImage *)activityViewController:(UIActivityViewController *)activityViewController thumbnailImageForActivityType:(NSString *)activityType suggestedSize:(CGSize)size
  {
      //Add image to improve the look of the alert received on the other side, make sure it is scaled to the suggested size.

      return self.productImage;
  }
