众多扩展

一组保存您的代码并可节省时间的 Swift 扩展。

特点

根据其依赖关系对扩展进行分组，这些依赖关系包括

• Foundation

  • CGPoint

    • 数学

    -CGPoint(x: -3, y: 5)                                       // {x 3 y -5}
    CGPoint(x: -3, y: 5) + 4                                    // {x 1 y 9}
    CGPoint(x: -3, y: 5) - 4                                    // {x -7 y 1}
    CGPoint(x: -3, y: 5) * 3                                    // {x -9 y 15}
    CGPoint(x: -3, y: 5) / 2                                    // {x -1.5 y 2.5}

  • CGSize

    • 数学

    -CGSize(width: 20, height: 54)                              // {w -20 h -54}
    CGSize(width: 20, height: 54) + 10                          // {w 30 h 64}
    CGSize(width: 20, height: 54) - 10                          // {w 10 h 44}
    CGSize(width: 20, height: 54) * 3                           // {w 60 h 162}
    CGSize(width: 20, height: 54) / 2                           // {w 10 h 27}

  • CGRect

    • 锚点，例如 topLeft、center、bottomRight

    let rect = CGRect(x: 5, y: -10, width: 50, height: 60)
    rect.topLeft                                                // {x 5 y -10}
    rect.topCenter                                              // {x 30 y -10}
    rect.topRight                                               // {x 55 y -10}
    rect.centerLeft                                             // {x 5 y 20}
    rect.center                                                 // {x 30 y 20}
    rect.centerRight                                            // {x 55 y 20}
    rect.bottomLeft                                             // {x 5 y 50}
    rect.bottomCenter                                           // {x 30 y 50}
    rect.bottomRight                                            // {x 55 y 50}

    • 锚点自动贴合

    let rect2 = CGRect(x: 25, y: 40, width: 100, height: 20)
    
    // Move `rect` such that it's top left is at `rect2`'s center
    rect.snapping(.topLeft, to: rect2.center)                   // {x 75 y 50 w 50 h 60}
    
    // Move `rect` such that it's bottom right is at `rect2`'s center left
    rect.snapping(.bottomRight, to: rect2.centerLeft)           // {x -25 y -10 w 50 h 60}

    • 边缘，例如 left、top

    rect.top                                                    // -10
    rect.left                                                   // 5
    rect.bottom                                                 // 50
    rect.right                                                  // 55

    • 边缘自动贴合

    // Move `rect` such that it's left is on `rect2`'s right
    rect.snapping(.left, to: rect2.right)                       // {x 125 y -10 w 50 h 60}
    
    // Move `rect` such that it's bottom is at `rect2`'s bottom
    rect.snapping(.bottom, to: rect2.bottom)                    // {x 5 y 0 w 50 h 60}

  • Bundle

    • Info.plist 值

    Bundle.main.releaseVersion                                  // returns CFBundleShortVersionString
    Bundle.main.buildVersion                                    // returns CFBundleVersion
    Bundle.main.displayName                                     // returns CFBundleDisplayName
    Bundle.main.shortName                                     // returns CFBundleName

• UIKit

  • UIEdgeInsets

    • 数学

    -UIEdgeInsets(top: 12, left: 6, bottom: -8, right: -10)     // {top: -12, left: -6, bottom: 8, right: 10}

    • 初始化方法

    UIEdgeInsets.all(value: 3)                                  // {top: 3, left: 3, bottom: 3, right: 3}
    UIEdgeInsets.symmetric(vertical: 10)                        // {top: 10, left: 0, bottom: 10, right: 0}
    UIEdgeInsets.only(left: 7, bottom: 3)                       // {top: 0, left: 7, bottom: 3, right: 0}

    • 水平/垂直求和

    let insets = UIEdgeInsets(top: 12, left: 6, bottom: 8, right: 10)
    insets.horizontals                                          // 16
    insets.verticals                                            // 20

  • UIImage
