# UIView-Positioning
**UIView+Positioning** is a Swift Extension which provides easy shorthand methods to defining the frame properties (width, height, x, y) of any UIView based object in an easy fashion, as well as extra helpful properties and methods.
### USAGE
Just use the properties **x**, **y**, **width**, **height** or use **origin** and **size** to kill two birds with one stone ;-)
```swift
let btnTest = UIButton() // Or any other view
btnTest.width = 250
btnTest.height = 100
btnTest.y -= 100
btnTest.x += 35
btnTest.centerX = 20
btnTest.centerY = 15
btnTest.size = CGSize(width: 150, height: 70)
btnTest.origin = CGPoint(x: 25, y: 10)
print(btnTest.lastSubviewOnX?.x) // X value of the object with the largest X value
print(btnTest.lastSubviewOnY?.y) // Y value of the object with the largest Y value
btnTest.centerToParent() // Centers button to its parent view, if exists
```
Here's another short example of using **centerToParent** and the Fibonacci Series to create multiple subviewed squares
```swift
var currentView = self.view
var currentSize: CGFloat = 300
for i in 0...12 {
let newView = UIView()
newView.size = CGSize(width: currentSize, height: currentSize)
newView.backgroundColor = UIColor.random
currentView?.addSubview(newView)
newView.centerToParent()
currentView = newView
currentSize -= CGFloat(self.fibonacci(i+6) / 10)
}
```
Will result in this:
### AVAILABLE PROPERTIES & METHODS
- **x**, **y**, **origin** - Positioning Shorthand
- **width**, **height**, **size** - Sizing Shorthand
- **left**, **bottom**, **top**, **right** - Representing X and Y values of the different sides of the view
- **centerX**, **centerY** - Shorthand for the X and Y of the View's Center
- **boundsWidth**, **boundsHeight** - Shorthand for the width and height of the View's bounds
- **boundsX**, **boundsY** - Shorthand for the X and Y position of the View's bounds
- **lastSubviewOnX**, **lastSubviewOnY** - Returns the Subview with the height X or Y value (closest to the right or closest to the bottom)
- **centerToParent** - Center the current view relatively to his superview, if one exists
### INSTALLATION
Add the following line to your `Podfile`:
`pod 'UIView+Positioning'`
and then run:
