SlangKing — map and player profile update

The key for app users to interact with the world is the map. By finding other users or players on the map constructs a mature social network for the specific app. The close feeling of nearby players give the user sense of secure and identity.

There are 3 features updated:

1. MapKit

MapKit Tutorial: Getting Started

2. Social image share

Add a new func with extension in UIView to screenshot the player profile page

//UIView extension which converts the UIView into an image.
extension UIView {
    func toImage() -> UIImage {
        UIGraphicsBeginImageContextWithOptions(bounds.size, false, UIScreen.mainScreen().scale)

        drawViewHierarchyInRect(self.bounds, afterScreenUpdates: true)

        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image
    }
}

Then present the UIActivityViewController with activityItems:[screenshot].

@IBAction func shareButtonPressed(_ sender: Any) {
let activityController = UIActivityViewController(activityItems: [self.view.toImage()], applicationActivities: nil)
present(activityController, animated: true, completion: nil)
}

3. Input image with camera or photo library

By using UIAlertController and UIImagePickerController gives the player two options to input their head photo.

UIImagePickerController:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print(“info \(info)”)
let image = info[UIImagePickerControllerOriginalImage] as? UIImage
mainPlayerImageView.image = image
dismiss(animated: true, completion: nil)
}

UIAlertController:

@IBAction func changePhotoButton(_ sender: Any) {
func chooseHowToPhoto() {
// setting alertController
let alertController = UIAlertController(title: “Photo”, message: “Choose from”, preferredStyle: .actionSheet)
// getting photo by camera
let cameraAction = UIAlertAction(title: “Camera”, style: .default) {(action: UIAlertAction!) -> Void in
let imagePicker = UIImagePickerController()
imagePicker.allowsEditing = true
imagePicker.sourceType = .camera
imagePicker.delegate = self
self.present(imagePicker, animated: true, completion: nil)
}
// getting photo by photo library
let photolibraryAction = UIAlertAction(title: “Photo Library”, style: .default) {(action: UIAlertAction!) -> Void in
let imagePicker = UIImagePickerController()
imagePicker.allowsEditing = true
imagePicker.sourceType = .photoLibrary
imagePicker.delegate = self
self.present(imagePicker, animated: true, completion: nil)
}
// add additional cancel button
let cancelAction = UIAlertAction(title: “Cancel”, style: .cancel, handler: nil)
alertController.addAction(cameraAction)
alertController.addAction(photolibraryAction)
alertController.addAction(cancelAction)
self.present(alertController, animated: true, completion: nil)
}
chooseHowToPhoto()
}

Also the data passing between controllers by func prepare and unwind segue. It will be updated to Notification to updated all the data to the game rather then profile only.
