SMCalloutView aims to be an exact replica of the private UICalloutView system control.
We all love those "bubbles" you get when clicking pins in MKMapView. But sadly, it's impossible to present this bubble-style "Callout" UI anywhere outside MKMapView. Phooey! So this class painstakingly recreates this handy control for your pleasure.
To use SMCalloutView in your own projects, simply copy the files
SMCalloutView, by default, will render in the new style introduced with
iOS 7. If you need the old style, simply include
SMClassicCalloutView.m in your project as well. There is a special
+[SMCalloutView platformCalloutView] which will
automatically select the appropriate callout class for the current platform.
The comments in
SMCalloutView.h do a lot of explaining on how to use the
class, but the main function you'll need is
specify the view you'd like to add the callout to, as well as the rect
defining the "target" that the popup should point at. The target rect should
be in the coordinate system of the target view (just like the similarly-
UIPopover method). Most likely this will be
target.frame if you're
adding the callout view as a sibling of the target view, or it would be
target.bounds if you're adding the callout view to the target itself.
You can study the included project's UIViewController subclasses for a working example.
If you use only the
title/titleView/subtitle/subtitleView properties, the
callout will always be the "system standard" height. If you assign the
contentView property however, then the callout will size to fit the
contentView and the other properties are ignored.
Yes, the callout background is an instance of
can set your own custom
View subclass to be the background, or you can use
one of the built-in subclasses:
SMCalloutMaskedBackgroundView renders an iOS-7 style background.
SMCalloutImageBackgroundView lets you specify each of the image
"fragments" that make up a horizontally-stretchable background.
SMCalloutDrawnBackgroundView draws the background at any size using
CoreGraphics methods. You can copy the
-drawRect method and change the
parameters to suit your needs.
Nope, but other intrepid coders have!

And for the outdoor map data and tiles themselves, check out Mapbox's iOS
SDK, a complete open-source solution for custom maps. They even use
SMCalloutView out of the box!
