Codemine 是一个包含对 Swift 项目有用的函数和语法糖的扩展集合。
要将 Codemine 作为 Swift 包管理器 包使用，只需将以下代码添加到您的 Package.swift 文件中。
import PackageDescription
let package = Package(
name: "YourPackage",
dependencies: [
.Package(url: "https://github.com/nodes-ios/Codemine.git", majorVersion: 0)
]
)注意：目前这不会工作，因为 SPM 不支持 iOS，但我们将在它支持后立即支持它！ :)
let appName = Application.name // CFBundleDisplayName : String
let appVersion = Application.version // CFBundleShortVersionString : String
let appExecutable = Application.executable // CFBundleExecutable : String
let appBundle = Application.bundle // CFBundleIdentifier : String
let appSchemes = Application.schemes // CFBundleURLSchemes : [String]
let mainAppScheme = Application.mainScheme // CFBundleURLSchemes.first : String?轻松访问主包信息。
let point1 = CGPoint(x: 5, y: 5)
let point2 = CGPoint(x: 5, y: 6)
print(point1.isCloseTo(point2, tolerance: 1)) // true
print(point1.isCloseTo(point2, tolerance: 0.5)) // false
print(point1+point2) // (10, 11)
print(point1*point2) // (25, 30)
print(point1*2) // (10, 10)
print(point1-point2) // (0, -1)
print(point1/point2) // (1, 0.83)
print(point1/5) // (1, 1)var rect = CGRect(x: 10, y: 10, width: 120, height: 100)
rect.x = 50
print(rect) // outputs x:50, y:20, width: 120, height:100
rect.y = -10
print(rect) // outputs x:50, y:-10, width: 120, height:100
let reversedRect = rect.rectByReversingSize()
print(reversedRect) // outputs x:50, y:-10, width:100, height:120let size1 = CGSize(width: 20, height: 40)
let size2 = CGSize(width: 121, height: 576)
print(size1+size2) // CGSize(width: 141, height: 616)dispatch {
// dispatch in main queue
}
dispatch(queue: .Background) {
// dispatch in background queue
}
lazy var serialQueue = dispatch_queue_create("serialQueue", DISPATCH_QUEUE_SERIAL)
dispatch(queue: .Custom(serialQueue)) {
// dispatch in a serial queue
}使用 Grand Central Dispatch 容易地进行调度。支持所有常规的全局队列：Main、Interactive、Initiated、Utility、Background。以及用于您自己的调度队列的：.Custom()。
let error = NSError(domain: domain, code: code, description: description)而不是
let error = NSError(domain: domain, code: code, userInfo: [NSLocalizedDescriptionKey : description])guard let url = NSURL(string: "https://example.com/image.png") else { return }
let size = CGSize(width: 512, height: 256)
let heightParameterName = "height"
let widthParameterName = "width"
let url2 = url.urlByAppendingAssetSize(size, mode: .Default, heightParameterName: heightParameterName, widthParameterName: widthParameterName)
print(url2.absoluteString) // on an @2x screen: "https://example.com/image.png?width=1024&height=512"该方法将 size 乘以 UIScreen.mainScreen().scale 添加到资产 URL，以便资产在屏幕上显示正确的尺寸。
let camelCaseStr1 = "userId"
let camelCaseStr2 = "isUserActiveMemberOfCurrentGroup"
print(camelCaseStr1.camelCaseToUnderscore()) // "user_id"
print(camelCaseStr2.camelCaseToUnderscore()) // "is_user_active_member_of_current_group""[email protected]".isValidEmailAddress() // true
"email.example.com".isValidEmailAddress() // falselet str = "Hello world!"
let range = str.rangeFromString("e", toString: " w") // Range(1..<7)let red = UIColor(rgb: 0xFF0000)let image = UIImage.imageFromColor(UIColor.redColor(), CGSize(width: 512, height: 256), cornerRadius:4.0)返回用红色填充、指定大小和指定圆角的 UIImage。
let image = UIImage.imageByEmbeddingIconIn(UIImage(named:"profilePhoto"), icon: UIImage(named:"favouriteIcon"))返回通过在第一张图片上覆盖图标组成的 UIImage。
let view = UIView.viewWithNibNamed("customView")返回从指定的 nib 创建的视图。
let view = UIView(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
view.roundViewCorners(UIRectCorner.AllCorners, radius: 4.0)将 UIView 指定角的圆角转换为指定的半径。
let UIView().then {
$0.backgroundColor = UIColor.blackColor()
}
