Swift Add click Gestures to Controls

Today, a colleague asked me how to add a click Method in TableView's Headerview, and today it is simple to explain that the way to add a click gesture in Swift is:

ImagePath. Addgesturerecognizer(UITapGestureRecognizer( target: Self, Action: "Imagepathclick:"))

What, seems to be more simple than OC, simply explain, ImagePath is my definition of a uiimageview, maybe someone added this gesture will find that why click this control does not work? The reason is that you may not have open user interaction, many controls , the default is not to accept user interaction, such as ImageView, such as label. So we need to let the control receive a click, enter the following code

ImagePath . userinteractionenabled = true
