Create a segue in the Interface Builder, give it a unique identifier, then call that segue in your code using

[self performSegue:@"segueIdentifier" sender:self];

回答2:

You have to embed the button's view controller in a UINavigationController, otherwise you will get an error like this:

Terminating app due to uncaught exception 'NSGenericException', reason: 'Push segues can only be used when the source controller is managed by an instance of UINavigationController.'

Once I put it in a UINavigationController, it transitioned just fine in my tests.

If you do not want a UINavigationController, you can set the segue to Modal, and it should also transition to the Tab Bar, but modally.
