iOS Tutorial GoogleMaps Tutorial

The iGoogleMaps library allows you to show a map inside your app:

It is similar to B4A GoogleMaps library.

In order to use it you need to get a free api key from Google. Follow the "Obtaining an API Key" steps: https://developers.google.com/maps/documentation/ios/start#obtaining_an_api_key
Start with the attached project. You will need to change the package name.

When you are ready to start a new project you need to:
Add these two attributes to your project (if you want to show the user location):

#PlistExtra:<key>NSLocationWhenInUseUsageDescription</key><string>Used to display the current navigation data.</string>
#PlistExtra:<key>NSLocationUsageDescription</key><string>Used to display the current navigation data.</string>

You can change the description text.

Copy the GoogleMaps.bundle folder from the example project (under Files\Special) to Files\Special in your project.

You can download the example project from: https://www.b4x.com/b4i/files/GoogleMaps.zip

Updates:

- Example updated with B4i v10+ and Google Maps v10.4.0 requirements. The bundle was updated.

copy to what libs directory? the application builder libs directory?

 

[Erel]

If you are using a local Mac builder then you need to copy the framework to the Libs folder that is under the builder folder.

 

[davepamn]

When you say copy GoogleMaps.Framework under macserver-aa/libs

will I see macserver-aa/Libs/GoogleMaps.Framework when done?

 

[Erel]

Yes. Note that the folder name is Libs not libs.

 

[davepamn]

I looked at the googlemaps example and saw the plist items were inserted in the project section of the code

 

[davepamn]

I created the "Key for iOS apps (with bundle identifiers)"

Build Configurations
Configuration Name=Default
Package: anywhere software.b4i.googlemaps

PrivateApiKeyAsString = "AIzaSyA-xxxxxxxxxx"

In the googlemaps demo code

I get a grey screen with no map. (Resolved)

It is working
I changed the version number and iTunes updated the code then the map display.
Great Job

How do I add a google Map to a tab controller Page?

I need to load google maps into a panel on my frmPage4 Layout.

gmap.Initialize("gmap", ApiKey)

    'Page4.RootPanel.AddView(gmap, 0, 0, 100%X, 100%y)

    panelMap.AddView(gmap, 0, 0, 100%X, 100%y)

    gmap.MapType = gmap.MAP_TYPE_TERRAIN

    gmap.GetUiSettings.CompassEnabled = True

    gmap.GetUiSettings.MyLocationButtonEnabled = True

    gmap.MyLocationEnabled = True

The app crashes when using this code.

 

[davepamn]

the error message is "Google Maps SDK for iOS to be part of your target under "Copy Bundle Resources""

I forgot to "Copy the GoogleMaps.bundle folder from the example project (under Files\Special) to Files\Special in your project."

I copied the "GoogleMaps.bundle" from sample data. Is that the correct process

 

[davepamn]

it is now working. Amazing

What is the procedure if no one uses local Mac builder but hosted builder?
Thank you

 

[Erel]

Follow the steps explained in the first post.

In B4A, it is possible to set 'showinfowindow' on true or false. This is usefull to update the infowindow, if the title or the snippet has changed. Is it possoble in B4i to update an markers infowindow, during the infowindow is shown?

 

[Erel]

Have you tried it?

 

[schimanski]

Yes, I have tested it. In b4a and b4i, it is not possible to update an open marker-window.

 

[Erel]

This is how GoogleMaps SDK works apparently.

 

[schimanski]

Ok. Thanks for your efforts.

 

[ciginfo]

Impossible to test the attached project GoogleMaps. I have changed the package name to "com.ciginfo.maps"
Below the 2 last lines of the error message

"Sending data to remote compiler. Error
Le thread a été abandonné."

 

[Erel]

Can you post a screenshot of this error? How long did it take until you see it?

 

[ciginfo]

It appears 25 or 30 seconds after
