问题:

I would like to create a UIViewController with various options, each can be enabled/disabled with a UISwitch. I'm using Xcode 5 and iOS 7 deployment target. The UITableView contains static cells. The interface is created in a storyboard.

When I'm adding a UISwitch to a cell (to it's contentView) I get this error:

Exception while running ibtool: *** setObjectForKey: object cannot be nil (key: objectID)

Isn't it possible to add a UISwitch to a static UITableViewCell? When removing the UISwitch the error disappears.

回答1:

I have the exact problem today and I couldn't figure out what is causing my problem because I have added too many items on my view controller. Now I know it is the UISwitch.

But I have resolved the problem, nonetheless.

I disabled the "Accessibility" option and the build was successful.

But How come the "Accessibility" option becomes an issue of Object Id remains unclear.

回答2:

For static table cells one has use to a UITableViewController. Static cells are not supported by UITableView.

A bit late but to the game, but...

If you define a User Defined Runtime Attribute to an AutoLayout constraint that is a Placeholder (i.e. removed at build time), you get this error.
