1. 图标按钮

• 在appDelegate中实现这个方法

  //3DTouch
  func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
      if shortcutItem.type == "OpenDoor" {
          root?.openDoorBtn.sendActions(for: .touchUpInside)
      }
  }

• 在info.plist中实现一些属性
  

2. 程序内的3DTouch

self.registerForPreviewing(with: self, sourceView: self.tableView)


func previewingContext(_ previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
    guard let index = tableView.indexPathForRow(at: location)else{
        return nil
    }

    let cell = tableView.cellForRow(at: index)
    let model = self.dataSource[index.row]
    let detailVC = NoticeDetailController()
    detailVC.model = model
    detailVC.preferredContentSize = CGSize(width:0,height:0)
    previewingContext.sourceRect = cell!.frame
    
    return detailVC
}
