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.
Just use the properties x, y, width, height or use origin and size to kill two birds with one stone ;-)
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 existsHere's another short example of using centerToParent and the Fibonacci Series to create multiple subviewed squares
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:
-
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
Add the following line to your Podfile:
pod 'UIView+Positioning'
and then run:
$ pod install
