cs193p – Smashtag Update Swift 1.2

Please note, this blog entry is from a previous course. You might want to check out the current one.

To run the Smashtag code with Swift 1.2. are quite extensive:

  • countElements() is now called count()
  • as needs to be replaced with as!
  • reduce() requires the combine parameter named explicitly
  • same with custom methods, its now quite strict …
  • let is now more restrictive, some parameters have to be changed to var (it might be I went a little bit over board here)
  • NSString is no String any more and needs to be cast explicitly
  • if a parameter is set within a closure of the init method, set a default value outside

The updated code is available on GitHub.

Mameli for Constantinus

The Austrian Professional Association of Management Consultancy and Information Technology has created the CONSTANTINUS Award to promote excellence in consulting and IT-services.
It has become the leading national award for knowledge-based services in Austria and has been recognized by the Austrian Federal Government as the sole qualifying process for the Federal State Award.

I submitted an app, called Mameli. It’s an reading book which helps children learn reading and thematizes xenophobia and demarcation.

And because there is an Audience Award for which you can vote on Facebook, I would really like to ask you to do so!

Unfortunately it is in German only, but it should not be too hard to find the text “Mameli” and click on the vote button 😉

cs193p – Project #5 Assignment #5 Step #5 – The Configuration

Please note, this blog entry is from a previous course. You might want to check out the current one.

For the configuration – the settings of the game – create a new class which will handle the communication with the user defaults. Most of the variables stored in the settings are optional, as a way when to use default values.

The columns and the rows setting hold the dimensions of the level “one” of the brick wall:

    struct Const {
        static let ColumnsKey = "Settings.Columns"
        static let RowsKey = "Settings.Rows"
    }

    let defaults = NSUserDefaults.standardUserDefaults()

    var columns: Int? {
        get { return defaults.objectForKey(Const.ColumnsKey) as? Int}
        set { defaults.setObject(newValue, forKey: Const.ColumnsKey) }
    }

    var rows: Int? {
        get { return defaults.objectForKey(Const.RowsKey) as? Int}
        set { defaults.setObject(newValue, forKey: Const.RowsKey) }
    }

cs193p – Project #5 Assignment #5 Step #4 – The Alert

Please note, this blog entry is from a previous course. You might want to check out the current one.

That’s a quick one. In the last completion block of the destroy animation check if there are any bricks left:

    private func destroyBrickAtIndex(index: Int) {
        ...
                    ...
                    UIView.animateWithDuration(1.0, animations: {
                        ...
                        }, completion: { (success) -> Void in
                            ...
                            ...
                            if self.bricks.count == 0 {
                                self.levelFinished()
                            }
                    })
            ...
    }

cs193p – Project #5 Assignment #5 Step #3 – The Bricks

Please note, this blog entry is from a previous course. You might want to check out the current one.

A new structure provides two sets of information – the view of the brick and its relative frame information (without information about the current device information). Store this structure for each brick in a dictionary:

    var bricks = [Int:Brick]()
    
    struct Brick {
        var relativeFrame: CGRect
        var view: UIView
    }

cs193p – Project #5 Assignment #5 Step #2 – The Paddle

Please note, this blog entry is from a previous course. You might want to check out the current one.

Create the paddle lazily. Place it outside (just a little bit) of the game view – which perhaps a bad way to know if it has been created recently. … and make it nice and colorful, with rounded corners etc …

    struct Constants {
        static let PaddleSize = CGSize(width: 80.0, height: 20.0)
        static let PaddleCornerRadius: CGFloat = 5.0
        static let PaddleColor = UIColor.greenColor()
    }

    lazy var paddle: UIView = {
        let paddle = UIView(frame: CGRect(origin: CGPoint(x: -1, y: -1), size: Constants.PaddleSize))
        paddle.backgroundColor = Constants.PaddleColor
        paddle.layer.cornerRadius = Constants.PaddleCornerRadius
        paddle.layer.borderColor = UIColor.blackColor().CGColor
        paddle.layer.borderWidth = 2.0
        paddle.layer.shadowOffset = CGSize(width: 2.0, height: 2.0)
        paddle.layer.shadowOpacity = 0.5
        
        self.gameView.addSubview(paddle)
        
        return paddle
    }()
