Sulcino’s Deck of Tarot App apha

DavidRak 2016-08-11 No Comments

This is preview of app I’m working on. Many features I have on todo list, e.g. spreads editor, more natural shuffle, iCloud sync etc.

But in the first place I need some tarot decks I can legally use. So if you know some free to use deck, or you create tarot cards and would be willing to provide them for this app under some conditions, please let me know.

Vector Layer Animation Basics Cheat Sheet

DavidRak 2016-05-22 No Comments

Take some UIView

let myView = UIView(frame: CGRect(origin: CGPoint(x: 0, y: 0),
                                  size: CGSize(width: 200, height: 200)))

let myView = UIView(frame: CGRect(origin: CGPoint(x: 0, y: 0),

size: CGSize(width: 200, height: 200)))

Make and setup layer for vector shape

let myLayer = CAShapeLayer()
// setup combining of paths if they overlap
myLayer.fillRule = kCAFillRuleEvenOdd
// set colors of shapes
myLayer.fillColor = UIColor.blackColor().CGColor
myLayer.strokeColor = UIColor.redColor().CGColor
// set thick of stroke
layer.lineWidth = 2.0

let myLayer = CAShapeLayer()

// setup combining of paths if they overlap

myLayer.fillRule = kCAFillRuleEvenOdd

// set colors of shapes

myLayer.fillColor = UIColor.blackColor().CGColor

myLayer.strokeColor = UIColor.redColor().CGColor

// set thick of stroke

layer.lineWidth = 2.0

Make path for shape layer

// we'll need CGPath,
// but UIBezierPath has friendlier methods for drawing shapes
let myPath = UIBezierPath()
// draw shape
myPath.moveToPoint(CGPoint(x: 0, y: 0))
myPath.addLineToPoint(CGPoint(x: myView.bounds.width * 0.7, y: 0))
myPath.addLineToPoint(CGPoint(x: myView.bounds.width * 0.7, y: myView.bounds.height * 0.7))
myPath.addLineToPoint(CGPoint(x: 0, y: myView.bounds.height * 0.7))
myPath.closePath()

// we'll need CGPath,

// but UIBezierPath has friendlier methods for drawing shapes

let myPath = UIBezierPath()

// draw shape

myPath.moveToPoint(CGPoint(x: 0, y: 0))

myPath.addLineToPoint(CGPoint(x: myView.bounds.width * 0.7, y: 0))

myPath.addLineToPoint(CGPoint(x: myView.bounds.width * 0.7, y: myView.bounds.height * 0.7))

myPath.addLineToPoint(CGPoint(x: 0, y: myView.bounds.height * 0.7))

myPath.closePath()

Add path to layer

myLayer.path = myPath.CGPath

1 2	myLayer.path = myPath.CGPath

Add layer to view

view.layer.addSublayer(myLayer)

1 2	view.layer.addSublayer(myLayer)

Now our view shows our brand new vector shape. Now we’ll animate it.

Prepare target shape for our animation

let targetPath = UIBezierPath()
targetPath.moveToPoint(CGPoint(x: myView.bounds.width * 0.3, y: myView.bounds.height * 0.3))
targetPath.addLineToPoint(CGPoint(x: myView.bounds.width, y: myView.bounds.height * 0.3))
targetPath.addLineToPoint(CGPoint(x: myView.bounds.width, y: myView.bounds.height))
targetPath.addLineToPoint(CGPoint(x: myView.bounds.width * 0.3, y: myView.bounds.height))
targetPath.closePath()

let targetPath = UIBezierPath()

targetPath.moveToPoint(CGPoint(x: myView.bounds.width * 0.3, y: myView.bounds.height * 0.3))

targetPath.addLineToPoint(CGPoint(x: myView.bounds.width, y: myView.bounds.height * 0.3))

targetPath.addLineToPoint(CGPoint(x: myView.bounds.width, y: myView.bounds.height))

targetPath.addLineToPoint(CGPoint(x: myView.bounds.width * 0.3, y: myView.bounds.height))

targetPath.closePath()

Setup animation

let animation = CABasicAnimation(keyPath: "path")
// shape on the beginning of animation
// we can use current shape on the layer by
// (view.layer.presentationLayer() as? CAShapeLayer)?.path
animation.fromValue = path.CGPath
// shape on the end of animation
animation.toValue = targetPath.CGPath
animation.duration = 2.0
animation.removedOnCompletion = false
animation.fillMode = kCAFillModeBoth

let animation = CABasicAnimation(keyPath: "path")

// shape on the beginning of animation

// we can use current shape on the layer by

// (view.layer.presentationLayer() as? CAShapeLayer)?.path

animation.fromValue = path.CGPath

// shape on the end of animation

animation.toValue = targetPath.CGPath

animation.duration = 2.0

animation.removedOnCompletion = false

animation.fillMode = kCAFillModeBoth

Add animation to layer

// if there can be another animations, you can remove them
myLayer.removeAllAnimations()
// add animation to layer
myLayer.addAnimation(animation, forKey: animation.keyPath)

// if there can be another animations, you can remove them

myLayer.removeAllAnimations()

// add animation to layer

myLayer.addAnimation(animation, forKey: animation.keyPath)

That’s all. Easy, isn’t it?

CoreData Basics Cheat Sheet

DavidRak 2016-05-03 No Comments

Get app delegate

let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate

1 2	let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate

Get context

let managedContext = appDelegate.managedObjectContext

1 2	let managedContext = appDelegate.managedObjectContext

Get entity

let entity = NSEntityDescription.entityForName("Toy", inManagedObjectContext: managedContext)

1 2	let entity = NSEntityDescription.entityForName("Toy", inManagedObjectContext: managedContext)

Get managed object

let toy = NSManagedObject(entity: entity!, insertIntoManagedObjectContext: managedContext)

1 2	let toy = NSManagedObject(entity: entity!, insertIntoManagedObjectContext: managedContext)

Add value to managed object

toy.setValue(name, forKey: "name")

1 2	toy.setValue(name, forKey: "name")

Save context

do {
    try managedContext.save()
} catch let error as NSError {
    print("Could not save \(error), \(error.userInfo)")
}

do {

try managedContext.save()

} catch let error as NSError {

print("Could not save \(error), \(error.userInfo)")

}

Fetching from Core Data

let fetchRequest = NSFetchRequest(entityName: "Toy")
do {
    let results = try managedContext.executeFetchRequest(fetchRequest)
    toys = results as! [NSManagedObject]
} catch let error as NSError {
    print("Could not fetch \(error), \(error.userInfo)")
}
