iOS shortcutItem点出分享界面的问题

Question

退出3dtouch之后很多应用都可以通过shortcutitem里面分享。但是我自己试了一下，代码如下：

• (void) application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
  {
  if ([shortcutItem.type isEqualToString:@"PBShorcutItem_Share"])
  {
  NSString *shareText = @"分享一下~";
  UIImage *shareImage = [UIImage imageNamed:@"Icon"];
  NSArray *activityItems = @[shareText, shareImage];
  UIActivityViewController *activityVctl = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];

  [self.window.rootViewController presentViewController:activityVctl animated:YES completion:^{
  
  }];
  

  }
  }

就是这样的UIActivityViewController是在进入app之后才会弹出来，如何让这个分享界面在桌面弹出？
