I have a MapView and I want to display a black semi transparent rectangle

  • 0

I have a MapView and I want to display a black semi transparent rectangle on top with a text inside. Not over the entire map only on section of it (maybe on the top corner) just as an info box (like the one in the iPod player that appears on double tap and displays the Mute and skip buttons).

I tried google but I’m not getting any clear answers. How is the best way to accomplish this?

Thanks in advance

    Can be easily done with interface builder:

    enter image description here

    View Hierarchy

    NOTE The background has to be a separate view which is the first entry in the list of controls, so it is in the background. Setting the container view to an alpha value below 1 will also be inherited by the subviews, which is not displayed in the interface builder

    enter image description here

    Settings for view "view with clear color bg and alpha 1.0"

    enter image description here

    Settings for view "black translucent bg view"

    enter image description here
