Ruler
In some cases, we need to distinguish between different devices to set UI, but Adaptive Layout can not do that. So, there is a Ruler.
Requirements
Swift 4, iOS 8.0
(Swift 3, use version 1.0.1)
Example
If we only consider iPhone's width, iPhone 5 has the same width of iPhone 4s, iPhone 6 has a bigger width, iPhone 6 Plus' width even bigger than iPhone 6, and iPhone X's width is the biggest. Only four widths.
But if we consider full screen size of iPhone, there are five models, because iPhone 5's height is different from iPhone 4s'.
If our app is universal, we need consider iPad, there are two models (in points).
So all we need consider five cases as follows:
enum Ruler<T> {
case iPhoneHorizontal(T, T, T)
case iPhoneVertical(T, T, T, T, T)
case iPad(T, T)
case universalHorizontal(T, T, T, T, T)
case universalVertical(T, T, T, T, T, T, T)
}
In real world (thanks generics, Ruler can match anything for different sizes of iOS devices):
import Ruler
// size, off course
let width = Ruler.iPhoneHorizontal(10, 20, 30).value
let height = Ruler.iPhoneVertical(5, 10, 20, 30, 40).value
// or color
colorView.backgroundColor = Ruler.universalVertical(UIColor.black, UIColor.red, UIColor.blue, UIColor.green, UIColor.yellow, UIColor.purple, UIColor.cyan).value
// even closures
typealias Greeting = () -> Void
let greeting: Greeting = Ruler.universalVertical(
{ print("Hello!") },
{ print("Hi!") },
{ print("How are you!") },
{ print("How do you do!") },
{ print("好久不见!") },
{ print("你好!") },
{ print("很高兴见到你!") }).value
greeting()
// ...
Special offer
Detect if this device is an iPhone X:
if ScreenModel.isPhoneX {
print("It's an iPhone X. You're rich!")
}
