Understanding Google Play Game Services on iOS: A Deep Dive into Rotating Toast Messages

Introduction

As game developers, we often rely on third-party libraries and services to enhance our gaming experiences. Google Play Game Services is one such service that provides a range of features to make our games more engaging and competitive. In this article, we’ll delve into the world of Google Play Game Services on iOS, focusing specifically on rotating toast messages in landscape mode.

What is Google Play Game Services?

Google Play Game Services (PGS) is a free library provided by Google that enables developers to add social features, leaderboards, achievements, and more to their mobile games. It allows players to compete with each other, track progress, and earn rewards, all while providing a seamless gaming experience.

Understanding the GPGManager

The GPGManager is a class in the Google Play Game Services SDK that manages game-related data and services on the client-side. It provides methods for initializing the service, setting up leaderboards, achievements, and more. In this article, we’ll focus on using the GPGManager to rotate toast messages.

Valid Orientation Flags

In iOS 8, the validOrientationFlags parameter of the setActivityOptions method in GPGManager was deprecated. This meant that developers had to use a different approach to achieve their desired orientation behavior.

What is Activity Options?

Activity options determine how a game’s activity should be managed when the system needs to switch between tasks or perform other actions. These options can include setting the orientation of the game, hiding the UI, and more.

Rotating Toast Messages in Landscape Mode

To rotate toast messages in landscape mode on iOS 8, we need to use a different approach than the deprecated validOrientationFlags parameter.

Step 1: Set the Orientation Option

We need to set the orientation option of the activity using the setActivityOptions method. To achieve this, we’ll create an instance of GPGManager and call the setActivityOptions method with a specific orientation option set.

- (void)rotateToastMessage:(UIImage *)image {
    // Create a new GPGManager instance
    self.gpgManager = [[GPGManager alloc] init];

    // Set the activity options to rotate the toast message in landscape mode
    ActivityOptions options = [[ActivityOptions alloc] initWithCategory:ActivityCategoryShow];
    [self.gpgManager setActivityOptions:options orientation:UIInterfaceOrientationLandscapeLeft];
}

Step 2: Update the Toast Message

Once we’ve set the activity options, we need to update our toast message UI to reflect the new rotation.

Step 4.1: Create a New View Controller

Create a new view controller that will display the toast message. We’ll use this view controller to rotate our toast message in landscape mode.

- (void)showToastMessage:(UIImage *)image {
    // Create a new UIViewController instance
    UIViewController *viewController = [[UIViewController alloc] init];

    // Set the view of the view controller to our toast message UI
    viewController.view = [self createToastMessageUI:image];

    // Add the view controller as a child to the main window
    [[UIApplication sharedApplication].keyWindow].rootViewController addChild:viewController;
}

Step 5: Rotate the Toast Message

To rotate the toast message, we’ll use the UIView class and its built-in rotation properties.

- (UIView *)createToastMessageUI:(UIImage *)image {
    // Create a new UIView instance
    UIView *view = [[UIView alloc] init];

    // Set the background image of the view to our toast message UI
    view.backgroundColor = [UIColor clearColor];
    view.addSubview:self.createToastImage:image];

    // Add rotation properties to the view
    [view setTransform:[CATransform3D transform]];
    [view setLayer:YES];

    return view;
}

Conclusion

Rotating toast messages in landscape mode on iOS 8 can be achieved by using a different approach than the deprecated validOrientationFlags parameter. By setting activity options and updating our toast message UI, we can ensure that our game’s toast message is properly rotated to reflect the user’s orientation.

While Google has replaced the deprecated method with a new one, it’s still essential for developers to understand the underlying concepts of Google Play Game Services on iOS and how they interact with each other. By following this article, you should now have a better understanding of rotating toast messages in landscape mode and how to achieve this using the GPGManager.

Troubleshooting Common Issues

Here are some common issues that might arise when trying to rotate toast messages:

Orientation is not being applied: Make sure that you’ve set the activity options correctly using the setActivityOptions method.
Toast message is not rotating: Verify that your toast message UI is properly set up and that you’re updating it with the correct rotation properties.
