Setting background image for PFQueryTableViewController

问题

Swift iOS
xcode 7.1 Beta

I am trying to set background image on the PFQueryTableViewController. I tried dragging the table from the story board (Ref. outlet: tableView) but I am not able to make the code work referring to that outlet.

    let image = UIImage(named: "Background")
    tableView.backgroundView = UIImageView(image: image)

The app crashes stating:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle:.

I even tried setting the background color tableView.backgroundColor = UIColor.greenColor()

But again, the app crashes

Can someone explain what's going on in here? I searched online, but most of the posts are only related to fetching images inside the PFQueryTableViewController cell.

回答1:

Try using the same code inside the queryForTable() block that returns query. It should work. No need of reference outlet.

Code should be something like:

override func queryForTable() -> PFQuery {

  let image = UIImage(named: "YourImageName")
  tableView.backgroundView = UIImageView(image: image)

  // your PFQueryTableViewController query goes here.... 

  return query
}
