How to detect long press or double tap or swipe on UI button (Unity 4.6)?

I am already a few days trying to figure out how can I detect if a few buttons existed long press touch, the new UI interface Unity 4.6 in C #.

Sorry for my bad english, and if I can help or explain would be grateful. I want to have multiple buttons, and each of whether the user has exercised long press touch.

 

Hi axcs,

Here is one easy solution for detecting long press.

1) First of all, I would add an Event Trigger component to each one of my buttons.
2) On the Event Trigger component of each button, I would add an event type for Pointer Down and an event type for Pointer Up.
3) I would then code my Pointer Down and Pointer Up to create a 'long press'.

The function triggered by Pointer Down will be something like this:
public void PointerDown()
{
StartCoroutine(LongPressResult());
}

The function triggered by Pointer Up will be something like this:
public void PointerUp()
{
StopCoroutine(LongPressResult());
}

Finally, you need to code the following which is what will happen on a long press, as well as defining how long is a 'long press'.

public float LongPressDuration; // you should set this equal to the duration you want for a long press, e.g. 2 seconds.
public IEnumerator LongPressResult()
{
yield return new WaitForSeconds(LongPressDuration);
// Here type the code for what you want to happen at the end of the long press
}

I hope this helps!
