Add the following line to your Cartfile.
github "isair/ManualLayout" Then do carthage update. After that, add the framework to your project.
Add the following line in your Podfile.
pod "ManualLayout" Just import ManualLayout in your code and use the methods and properties provided by the library to layout your views. You can check out the cheat sheet below for a compact list of everything. There are also example projects to get you started.
The smart assign operator =~ has only one job; to make your life easier.
someView.origin =~ (0, 20) anotherView.size =~ (100, 100) yetAnotherView.frame =~ (0, 120, view.width, 100)// For fast positioning. var origin: CGPoint var x: CGFloat var y: CGFloat var center: CGPoint var centerX: CGFloat var centerY: CGFloat var top: CGFloat var right: CGFloat var bottom: CGFloat var left: CGFloat // For fast sizing. var size: CGSize var width: CGFloat var height: CGFloat // Alternate edges. Their names may change in the near future. var top2: CGFloat var right2: CGFloat var bottom2: CGFloat var left2: CGFloatThe difference between alternate edges and normal edges require a bit of explaining. Imagine we have a view at position (0, 0) of size (100, 100) named myView. If we do myView.right = 200, then its position is now (100, 0) and its size remains unchaged. However, back when our view was located at (0, 0), if we had done myView.right2 = 200, then myView would have still been at (0, 0) but would have had a size of (200, 100).
So basically, setting a normal edge's position drags the whole view along with that edge but setting an alternative edge's position drags just that edge. And don't worry if you, for example, try to drag a left edge past its view's right edge. Edge swapping is done automatically so you don't have to worry about it.
Just one method with two variants for now, and those are used for easy size calculations.
func sizeToFit(width: CGFloat, height: CGFloat) -> CGSize func sizeToFit(constrainedSize: CGSize) -> CGSizeSo let's say that you have a label inside a view and you want to lay it out with an inset of 4 points on all sides, you could easily do the following:
myLabel.sizeToFit(inset(myView.size, 4)) myLabel.origin =~ (4, 4)Done!
var contentWidth: CGFloat var contentHeight: CGFloat var contentTop: CGFloat // Always equal to 0. Read-only. var contentLeft: CGFloat // Always equal to 0. Read-only. var contentBottom: CGFloat // contentHeight alias. var contentRight: CGFloat // contentWidth alias. var viewportTop: CGFloat // contentOffset.y alias. var viewportLeft: CGFloat // contentOffset.x alias. var viewportBottom: CGFloat // conentOffset.y + view height var viewportRight: CGFloat // contentOffset.x + view widthAll UIViewController properties are read only. They offer easy read access to a controller's view's properties.
var bounds: CGRect var center: CGPoint var centerX: CGFloat var centerY: CGFloat var size: CGSize var width: CGFloat var height: CGFloat var top: CGFloat // Top layout guide y coordinate. var right: CGFloat // Equal to the width of the controller's view. var bottom: CGFloat // Bottom layout guide y coordinate. var left: CGFloat // Always equal to 0.These functions never modify the view/layer/rectangle/etc they are passed.
