CommonExtensions 2.0.0

Common Extensions for Swift are a collection of commonly used extensions to existing Swift and UIKit classes. These will be modified, added to and possibly removed as Swift develops as a language, and as I learn more about what Swift has to offer.

Suggestions and pull requests are welcomed and encouraged.

####UIView+SnapShot Captures a snapshot of a UIView.

// Take a snapshot
let snapshot:UIImage = captureMeView.captureSnapShot()

####UIColor+Hex Create UIColor with Hex values

// Change the background to RED
self.view.backgroundColor = UIColor.colorFromHex(0xFF0000)

// Change the background color back to white using hex color as a string
self.view.backgroundColor = UIColor.colorFromHex(string:"#FFFFFF")

####UIImage+Resize Resize and crop UIImage when you need to manipulate a UIImage, and not just it's UIImageView.

// Create an image
var testImage:UIImage = UIImage(named:"puppy-running.png")!

// Resize the image proportionately with a height
testImage = UIImage.resize(image: testImage, height: 50)

// Resize the image proportionately with a width
testImage = UIImage.resize(image: testImage, width:100)
        
// Resize the image proportionately with a scale
testImage = UIImage.resize(image: testImage, scale:0.5)
        
// Resize the image to fit in rectangle
testImage = UIImage.resize(image: testImage, rect:CGRect(x:0, y:0, width:150, height:40))
        
// Crop image with rectangle
testImage = UIImage.resize(image: testImage, rect: CGRect(x:0, y:0, width:100, height:100))

####UIImage+Color Creates a UIImage with a solid color. Can specify a image size (Defaults to 1x1).

// Create a red square image (1x1)
let redImage:UIImage = UIImage.image(fromColor: UIColor.red)

// Create a blue square image (10x10)
let blueImage:UIImage = UIImage.image(fromColor:UIColor.blue, imageSize: CGSize(width:10, height:10))

####NSDate+Locale NSDate+Locale contains convenience methods to get the current date as a String in different formats.

// Current date
let now:NSDate = NSDate()
println("Local: "  + now.getLocalizedDate())   // RESULT: Local Date: 07/02/2014
println("US Date: "     + now.getUSDate())     // RESULT: US Date: 07/02/2014
println("GB Date: "     + now.getGBDate())     // RESULT: GB Date: 02/07/2014
println("JP Date: "     + now.getJPDate())     // RESULT: JP Date: 2014/07/02

####NSDate+JSON NSDate+JSON converts JSON String to NSDate.

var date:Date = Date.date(fromJSONDate:"2014-04-25T15:03:21Z")
println("JSON Date: " + date.getLocalizedDate() )

// RESULT: JSON Date: 04/25/2014

####NSDate+Elapsed NSDate+Elapsed contains methods to get amount of time between two dates (DateComponenets, or string representing time between [Good for blog entries]).

// Calendar and offset components
let gregorian:NSCalendar = NSCalendar(calendarIdentifier: NSCalendar.Identifier.gregorian)!
var offsetComponents = NSDateComponents()
offsetComponents.month = -1

var fromDate:Date = gregorian.date(byAdding: offsetComponents as DateComponents, to:now, options:.matchFirst)!
println("Elapsed Time (month): " + Date.elapsedTime(fromDate: fromDate, toDate:now ) )

// RESEULT: Elapsed Time (month): Created 1 month ago
