Allow more annotation callout view customization

[friedbunny]

Our annotation callout view is currently hardcoded to a plain SMCalloutView and only offers custom title/subtitle text and customization of the left and right accessory views.

We should expose our SMCalloutView object and/or provide a delegate method for setting a custom callout view on a per annotation basis.

Possible duplicate of #1784

#1784 is a similar use case, but refers to adding arbitrary custom native views as annotations on top of the GL map view. This ticket refers to our existing callout view, which needs to be better exposed for customization.

Someone know if callout view customization will be avaible ?

@friedbunny Adding parity ticket as we already have this feature in Android release.

Hi, we need this feature at Mappy, I'm working on adding an API to set a custom callout view

new pull request done: #3322

Hi,

is this possible with the new pull request? I'd like to display a UIView instead of the default callout, is this achievable?

Thanks!

That's what I'm busy doing at the moment @YBthebest . You can do it by returning false for the annotationCanShowCallout delegate method and handling the annotation manually. For example show your custom UIView from that method with the information contained in the annotation (which already comes in as an argument in the annotationCanShowCallout method)

[RomainQuidet]

@byroncoetsee it's already done by this pull request #3322
@YBthebest Yes just pull the branch dedicated to #3322 and go to the demo app, there is an example.

@RomainQuidet sorry I'm fairly new to Github and its process, how can I pull your branch? I can't seem to find an URL

[RomainQuidet]

if you're new to github use the graphical app from github or bitbucket (I like sourceTree on MacOSX). From the graphical app, you have a remote source where you'll see all branches, find the one starting with 2211_ it's the one I worked on. then double click on it to pull it from the source.
If you're new to Git, read some doc about sources management!

[bloemy7]

Thanks for the tips, I have started reading all the docs !

For the time being, I am using SourceTree, and it's quite weird because in the "Remotes" => "origin" section, I see loads of branches, but the 2211 branch isn't there...

@YBthebest Sorry, it's not in MapBox repo yet, it's in our fork : https://github.com/Mappy/mapbox-gl-native

[bloemy7]

Will it be in the MapBox repo soon? Thanks for the great work

Fixed by #3456.
