6 | 7 | It's a layer-based NSButton subclass that animates the styles and colors between normal and active (pressed) state. 8 | 9 | This package is used in production by [Gifski](https://github.com/sindresorhus/Gifski). 10 | 11 | ## Requirements 12 | 13 | - macOS 10.13+ 14 | 15 | ## Install 16 | 17 | Add `https://github.com/sindresorhus/CustomButton` in the [“Swift Package Manager” tab in Xcode](https://developer.apple.com/documentation/xcode/adding_package_dependencies_to_your_app). 18 | 19 | ## Usage 20 | 21 | See the [source](Sources/CustomButton/CustomButton.swift) for what properties you can change and play with it in the [example app](Example). By default, it has no style. 22 | 23 | ```swift 24 | import Cocoa 25 | import CustomButton 26 | 27 | @main 28 | final class AppDelegate: NSObject, NSApplicationDelegate { 29 | @IBOutlet weak var window: NSWindow! 30 | 31 | func applicationDidFinishLaunching(_ notification: Notification) { 32 | let button = CustomButton() 33 | button.translatesAutoresizingMaskIntoConstraints = false 34 | button.title = "CustomButton" 35 | button.activeBackgroundColor = .systemPink 36 | button.borderWidth = 1 37 | button.borderColor = .systemPink 38 | button.cornerRadius = 5 39 | button.textColor = .systemPink 40 | button.activeTextColor = .white 41 | 42 | let contentView = window.contentView! 43 | contentView.addSubview(button) 44 | 45 | NSLayoutConstraint.activate([ 46 | button.centerXAnchor.constraint(equalTo: contentView.centerXAnchor), 47 | button.centerYAnchor.constraint(equalTo: contentView.centerYAnchor), 48 | button.widthAnchor.constraint(equalToConstant: 100), 49 | button.heightAnchor.constraint(equalToConstant: 30) 50 | ]) 51 | } 52 | } 53 | ``` 54 | 55 | The button can also be edited in Interface Builder, but Xcode is very buggy with `@IBDesignable`, so I would recommend using it only programmatically for now. 56 | 57 | ## FAQ 58 | 59 | #### Can you support Carthage and CocoaPods? 60 | 61 | No, but you can still use Swift Package Manager for this package even though you mainly use Carthage or CocoaPods. 62 | 63 | #### Won't SwiftUI make this moot? 64 | 65 | SwiftUI does indeed make it much easier to create custom-looking buttons, but SwiftUI is still immature and most companies will not be able to require macOS 10.15 for a long time. So this package will still be useful for multiple years to come. 66 | 67 | ## Related 68 | 69 | - [Defaults](https://github.com/sindresorhus/Defaults) - Swifty and modern UserDefaults 70 | - [KeyboardShortcuts](https://github.com/sindresorhus/KeyboardShortcuts) - Add user-customizable global keyboard shortcuts to your macOS app 71 | - [LaunchAtLogin](https://github.com/sindresorhus/LaunchAtLogin) - Add "Launch at Login" functionality to your macOS app 72 | - [DockProgress](https://github.com/sindresorhus/DockProgress) - Show progress in your app's Dock icon 73 | - [More…](https://github.com/search?q=user%3Asindresorhus+language%3Aswift+archived%3Afalse&type=repositories) 74 | 75 | You might also like my [apps](https://sindresorhus.com/apps). 76 | -------------------------------------------------------------------------------- /screenshot.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/sindresorhus/CustomButton/e7c72500005ae4f3ca29c102ad7f8175c68c396b/screenshot.gif --------------------------------------------------------------------------------
