Triggering actions on controls using sendActionsForControlEvents: will not pass a `UIEvent` to action:forEvent:

gistfile1.m

@implementation ViewController

- (void)triggerAction;
{
    [self.button sendActionsForControlEvents:UIControlEventTouchUpInside];
}

- (void)action:(id)sender forEvent:(UIEvent *)event;
{
    // event is UIEvent when triggered by a touch on the button.
    // event is ViewControler when triggered using sendActionsForControlEvents:
}
