Who to add a double tap like? "Instagram Like" in swift

I want to add a like button, when you double tap the view it shows the like, but I don't know how to do that, any ideas?

Andrés,

I'd suggest investigating using UITapGestureRecognizer, which is a subclass of UIGestureRecognizer. I haven't made a double-tap interface like you're describing, but I think that could be done by setting the numberOfTapsRequired property to 2.

Pasan covers using this class in the "Playlist Browser with Swift / Obj-C" course, so I'd check that out for implementation instructions. The specific video is called "Adding Touch Capabilities" in the "Building the Master and Detail Views" section.

When creating an app, in Xcode there are some gestures recognizers that can do that. :)
