How can I send a "UIControlEventValueChanged" event from my custom control?

ios objective-c uicontrolevents target-action

[self sendActionsForControlEvents:UIControlEventValueChanged];

This will call all registered targets (via addTarget:action:forControlEvents: that this event has happened.

Use this function where you deem should trigger a value has changed
