override func viewDidAppear(animated: Bool) {
	super.viewDidAppear(animated)

    print(self.tabBarHeight) // Works in NavigationController otherwise its 0
    print(self.navigationBarHeight) // Works in NavigationController otherwise its 0
    print(self.navBar) // Returns NavigationBar, works in NavigationController otherwise its nil
}

Easily navigate between UIViewControllers:

override func viewDidAppear(animated: Bool) {
	super.viewDidAppear(animated)

    let myViewController = myViewController()
    pushVC(myViewController) // Instead of navigationController?.pushViewController(myViewController, animated: true)

    popVC() // Instead of navigationController?.popViewControllerAnimated(true)

    presentVC(myViewController) // Instead of presentViewController(myViewController, animated: true, completion: nil)

view1.addSubview(view2)
view1.resizeToFitSubviews()
print(view1.frame) // (0.0, 0.0, 200.0, 200.0)

Easily resize your UIView according to its contents:

let label = UILabel(x: 0, y: 0, w: 20, h: 20)
print(label.frame) // (0.0, 0.0, 20.0, 20.0)
label.text = "I find your lack of faith disturbing."
print(label.frame) // (0.0, 0.0, 20.0, 20.0)

print(aview.frame) // (0.0, 0.0, 10.0, 10.0)
print(bview.frame) // (0.0, 10.0, 10.0, 10.0)
print(cview.frame) // (0.0, 20.0, 10.0, 10.0)
// This only works in reordering vertically

Ignore specific subviews while reordering:

let mainview = UIView(x: 0, y: 0, w: 100, h: 100)
let aview = UIView(x: 0, y: 0, w: 10, h: 10)
let bview = UIView(x: 0, y: 0, w: 10, h: 10)

print(newImage.getSizeAsKilobytes()) //396

Easily resize your images:

let image = UIImage(named: "lightsaber")!
print(image.size) // (800.0, 1420.0)

let newImage = UIImage.scaleTo(image: image, w: 50, h: 50)
print(newImage.size) // (50.0, 50.0)

let newImage2 = image.resizeWithWidth(100)
print(newImage2.size) // (100.0, 178.0)

let newImage3 = image.resizeWithHeight(100)
print(newImage3.size) // (57.0, 100.0)

Easily crop images:

let image = UIImage(named: "lightsaber")!
print(image.size) // (800.0, 1420.0)
let croppedImage = image.croppedImage(CGRect(x: 0, y: 0, w: 200, h: 100))
print(croppedImage.size) // (200.0, 100.0)

##UIColor Extensions

Easily initialize your colors:

let myColor = UIColor(r: 100, g: 100, b: 100) // Default alpha is 1
let myColor2 = UIColor(r: 100, g: 100, b: 100, a: 0.5)

Easily create gray colors:

let myColor = UIColor.Gray(100) // Equals 100,100,100 with alpha 1
let myColor1 = UIColor.Gray(100, alpha: 0.5) // Equals 100,100,100

Easily access individual color values:

let myColor = UIColor(r: 100, g: 55, b: 33)
print(myColor.redComponent) // 100
print(myColor.greenComponent) // 55
print(myColor.blueComponent) // 33
print(myColor.alpha) // 1

Easily create colors with HEX values:

let myColor = UIColor(hex: 0x233C64) // Equals 35,60,100,1
let myColor1 = UIColor(hexString: "0x233C64") // Equals 35,60,100,1
let myColor2 = UIColor(hexString: "0x233C64", alpha: 0.6) // Equals 35,60,100,0.6
let myColor3 = UIColor(hexString: "233C64") // Equals 35,60,100,1
let myColor4 = UIColor(hexString: "#233C64") // Equals 35,60,100,1
let myColor5 = UIColor(hexString: "not hex string") // nil

Easily get a random color:

let myRandomColor = UIColor.randomColor()

##UIFont Extensions

Easily declare common fonts:

let myFont = UIFont.HelveticaNeue(type: FontType.Bold, size: 15)
let myFont1 = UIFont.AvenirNext(type: FontType.Italic, size: 13)
let myFont2 = UIFont.Font(FontName.SanFranciscoDisplay, type: FontType.None, size: 20)

##UIButton Extensions

Easily initialize your buttons:

let myButton = UIButton(x: 0, y: 0, w: 100, h: 100, target: self, action: "myButtonClicked")

func myButtonClicked() {
    print("buttonPressed")
}

Easily change your buttons backgroundcolors according to its state:

let myButton = UIButton()
myButton.setBackgroundColor(UIColor.redColor(), forState: UIControlState.Normal)
myButton.setBackgroundColor(UIColor.blueColor(), forState: UIControlState.Selected)

##UIDevice Extensions

Easily access your device information:

print(UIDevice.idForVendor()) // 104C9F7F-7403-4B3E-B6A2-C222C82074FF
print(UIDevice.systemName()) // iPhone OS
print(UIDevice.systemVersion()) // 9.0
print(UIDevice.deviceName()) // iPhone Simulator / iPhone 6 Wifi
print(UIDevice.deviceModel()) // x86_64 / iPhone7,2
print(UIDevice.deviceModelReadable()) // Simulator / iPhone 6
print(UIDevice.deviceLanguage()) // en

Easily check if your system version is over a certain version:

print(UIDevice.isSystemVersionOver("8.1")) // true
print(UIDevice.isSystemVersionOver("9.3")) // false
// You might not need this after Swift2.0

##Block Objects

These objects use completion blocks instead of selectors, taken from: CEMKit-Swift

Easily initialize a BlockButton:

let button = BlockButton(x: 0, y: 0, w: 100, h: 100) { (sender) -> Void in
    print("Block button clicked!")
}

let button1 = BlockButton(x: 0, y: 0, w: 100, h: 100)
button1.addAction { (sender) -> Void in
    print("Block button clicked!")
}

// There are also BlockWebView, BlockTap, BlockPan, BlockSwipe, BlockPinch, BlockLongPress

##NSUserDefaults Extensions

let Defaults = NSUserDefaults.standardUserDefaults()
// Get values from NSUserDefaults
let userName = Defaults["userName"]

// Set values to NSUserDefaults
Defaults["userName"] = someUserName

##NSURL Extensions

let url = NSURL(string: "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=facebook")
if let queryParameters = url?.queryParameters {
    print(queryParameters["v"]) //Optional("1.0")
    print(queryParameters["q"]) //Optional("facebook")
    print(queryParameters["other"]) //nil
}
