11 | 12 | ## Requirements 13 | IBLayoutConstraint is written in Swift 5.0 and is available on iOS/Mac Catalyst 11.0 or higher. 14 | 15 | ## Installation 16 | 17 | ### Dependency Managers 18 |
19 | CocoaPods 20 | 21 | [CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. You can install it with the following command: 22 | 23 | ```bash 24 | $ gem install cocoapods 25 | ``` 26 | 27 | To integrate IBLayoutConstraint into your Xcode project using CocoaPods, specify it in your `Podfile`: 28 | 29 | ```ruby 30 | source 'https://cdn.cocoapods.org/' 31 | platform :ios, '11.0' 32 | 33 | pod 'IBLayoutConstraint' 34 | ``` 35 | 36 | Then, run the following command: 37 | 38 | ```bash 39 | $ pod install 40 | ``` 41 | 42 |
43 | 44 | ## Introduction 45 | 46 | The main thought of this framework is convinient way to configure constraint for each device in Interface Builder. 47 | Sometimes we need to change `constant`/`multiplier` value for `NSLayoutConstraint` only for specific device, for example, for iPhone 5s (4"). 48 | If this `UIView` with layout has special constraint for one device, we should do: 49 | 50 | 1. inheritance from `UIView` 51 | 2. add `outlet` to this view `@IBOutlet weak private var someConstraint: NSLayoutConstraint!` 52 | 3. add some code to change constraint's value for specific device 53 | ```Swift 54 | if UIDevice.current.isIPhone5() { 55 | someConstraint.constant = 290 56 | } 57 | ``` 58 | 59 | IBLayoutConstraint will takes responsibility for this cases. 60 | 61 | ## How to use 62 | 63 |
(!) Notice: This approach isn't quite obvious, and you should point out it in documentation of your project. 64 |
65 | 66 | 1. Find `constraint` for configuration in Interface Builder View in Xcode. 67 | 2. Go to `Indentity Inspector` for this `constraint` in right-side panel. 68 | 3. Change Class `NSLayoutConstraint` to `IBLayoutConstraint` 69 | 70 | If you want to specify `multiplier` value or `constraint`and `multiplier` toghether, you should use `IBMultiplierLayoutConstraint`. 71 | 72 | 4. Go to `Attributes Inspector` for this `constraint` in right-side panel. You'll see: 73 | 74 | #### IBLayoutConstraint 75 | 76 |
77 | IBLayoutConstraint 78 |
79 | 80 | #### IBMultiplierLayoutConstraint 81 | 82 |
83 | IBLayoutConstraint 84 |
85 | 86 | 5. Find the screen size in inches that matches your need. You'll see two textfields: 87 | 88 | `Width` - value for landscape mode 89 | 90 | `Height` - value for portrait mode 91 | 92 | Fill the text fields. The necessary value will be applied after initialization and will change accordingly after device rotation. 93 | 94 | ##### Note: You don't need specify values for all sizes,but you need specify values for 'width' and 'height' in one line - it is required (even if you don't support rotation). If values don't specified for some size - IBLayoutConstraint will work as NSLayoutConstraint. 95 | 96 | ## Contributing 97 | 98 | Issues and pull requests are welcome! 99 | 100 | ## Author 101 | 102 | Maksim Kurpa - [@maksim_kurpa](https://twitter.com/maksim_kurpa) 103 | 104 | ## License 105 | 106 | This code is distributed under the terms and conditions of the [MIT license](https://raw.githubusercontent.com/MaksimKurpa/IBLayoutConstraint/master/LICENSE). 107 | -------------------------------------------------------------------------------- /Sources/IBLayoutConstraint.swift: -------------------------------------------------------------------------------- 1 | // 2 | // IBLayoutConstraint.swift 3 | // IBLayoutConstraint 4 | // 5 | // Created by Maks Kurpa on 4/3/20. 6 | // Copyright © 2020 Maks Kurpa.
