How to add entitlements to your libGDX iOS game

Posted on: August 23rd, 2023 by Olu No Comments

Hi folks,

In this post, we will go over how to add an entitlement (capability) to your libGDX iOS game. we assume the app uses robovm to provide the iOS support.

We will assume you want to add Game Center capability to your app.

First, open xcode for a sample project, optionally with the same bundle identifier as your game app

Add the Game Center capability within Xcode by following the instruction here.

Check your provisioning profile to make sure it has the Game Center entitlement

Verify that you can build your sample iOS app using your distribution provisioning profile

If you get an error that the provisioning profile doesn’t contain the Game Centre entitlement, then go to apple developer portal and check the profile there

If the profile has expiration field set to invalid, that means the profile is out of date. click edit button to see the profile details page, then click save. check the profile again to make sure it has a valid expiry date (in the future).

Close and re-open xcode and make sure it fetches the latest provisioning profile

Then check for the entitlements file within your Xcode project. it will be a file with file name ending with .entitlements

Copy the entitlements file into your libgdx ios project. you can call it something like Entitlements.plist.xml

Next you need to configure robovm to add that entitlement. to do this, open your robovm config file (ios/robovm.xml) file and add the following line within the config tag.


That’s it. you can now build your iOS app with robovm resting assured that it has the desired capability.

That’s all for now. Till next time, happy game development.

How to suggest hymns using Yinkos Hymns Manager

Posted on: August 16th, 2023 by Olu No Comments

Hi folks,

In this article we will cover how to suggest hymns with YHM (Yinkos Hymns Manager).

First you visit the Suggestions screen. You can do this by clicking Suggest Hymns from the home screen.


Alternatively, from the top menu, click Hymns Management > Suggestions.


On the Hymns Suggestions page, you can suggest hymns for a given date by setting the selection mode and target date, then clicking Suggest.

Selection Mode means the approach you want to use to suggest hymns. There are 3 selection modes available:

1. Random
2. From Previous Selections
3. From Suggestions File.

We will explore these modes.

Random – suggest hymns randomly from certain sections of the Celestial Church of Christ hymn book. You can customise the sections by setting the Hymn Config in the Settings screen. You can see the sections being used by clicking on the Hymn Sections accordion in the page. YHM makes sure you don’t repeat hymns too often.

From Previous Selections – suggest hymns based on songs you have selected in the past. This can be very useful if you want to make sure you choose hymns that are familiar to your choir. In this mode, YHM would usually suggest hymns that were picked in a certain time range before the target date. By default this is between 63 and 120 days  before the target date. You can customize the time range on the Settings screen under the section: Time range for suggesting from Previous Hymns

From Suggestions File – suggest hymns based on songs from a Suggestions file you have uploaded to app Settings. This is useful if your choir has a list of hymns they are familiar with and would like to pick their hymns from that list. Click here to find out how to set up a suggestions file.

Note: if a hymn recording is available for a suggested hymn, then the suggestion is displayed in green font, otherwise it is displayed in black font.

For each suggestion, we display the section of the Celestial Church hymn book that the hymn belongs.

For each suggestion, we display a Save button. If you want to save the suggestion as a hymn record, all you have to do is click Save.

Also, if a hymn has already been selected and stored for a given position on a given date, then we display the stored hymn number along side the suggestion.


That’s all for now. Till next time, happy hymns management.

How to delete provisioning profiles for iOS application signing

Posted on: August 12th, 2023 by Olu No Comments

Hi folks,

In this post we cover how to delete provisioning profiles for iOS application signing. When developing iOS applications, you usually use to sign the application before you can deploy it on mobile devices or publish it to the App Store.

In case you run into a situation where you have one too many provisioning profiles in your Mac as seen in Xcode, RoboVM, etc, how do you delete the profile? Very simple:

Go to ~/Library/MobileDevice/Provisioning\ Profiles/.

Here you will find a list of all provisioning profiles recognized by your computer. if you click on a profile in Finder, you would see some details in the sidebar about the contents of the profile. This may help you recognize the profile more easily. Then simply delete it.

That’s all for now. Till next time, happy software development.
