NSButton Multiple clicks

问题

I have an IBAction of when the button is clicked to change my view. How can I handle multiple clicks for example if I click the button a second time to cause another action?

Or do I need to delete the button after it has been clicked and then create a new one in its place? If so how do I handle the click event?

You can check the clickCount of the mouseDown event:

if ([event clickCount] > 1)
{
    // ... do double-click action
}
else
{
    // ... do single-click action
}
