SetNeedsReadable

A collection of helper methods for UIView and calculated variables for CGFloat to help enhance readability.

Installation

Available through CocoaPods. To install, add the following line to your Podfile:

pod 'SetNeedsReadable'

Usage

Usage of the centering helper methods should be restricted to layoutSubviews:, viewDidLayoutSubviews: or animation blocks as appropriate. When used outside of these scenarios, the user is still responsible for marking the appropriate view as dirty with a call to setNeedsLayout. To use, simply import the SetNeedsReadable module where needed.

Centering

---

foo.centerAlongHorizontalAxis(of: bar)
foo.centerAlongVerticalAxis(of: bar)
foo.centerHorizontally(between: bar, and: baz)
foo.center(inside: bar)
foo.centerVertically(between: bar, and: baz)

Aligning Inside Another View

---

foo.alignInside(leftEdgeOf: bar)
foo.alignInside(rightEdgeOf: bar)
foo.alignInside(topEdgeOf: bar)
foo.alignInside(bottomEdgeOf: bar)

Aligning Outside Another View

---

foo.alignOutside(leftEdgeOf: bar)
foo.alignOutside(rightEdgeOf: bar)
foo.alignOutside(topEdgeOf: bar)
foo.alignOutside(bottomEdgeOf: bar)

Animating

---

The methods can also be invoked inside animation blocks.

UIView.animate(withDuration: duration, delay: delay, options: [], animations: {

  self.foo.centerHorizontally(between: self.bar, and: self.baz)
  self.foo.centerVertically(between: self.bar, and: self.baz)
})

There is an example project in the repository that demonstrates usage.
