TouchUpInside doesn't recognize more than one click

Question

The nextButton only responds to the first click.

Do I need to implement something else to recognize more clicks?

nextButton.TouchUpInside += (s, e) =>
{

};

Answer 1

Set nextButton.MultipleTouchEnabled = true (or, in Swift 3, nextButton.isMultipleTouchEnabled = true) to allow multiple touches to be processed at once.
