{ 25 | didSet { 26 | let panGestureRecognizer = UIPanGestureRecognizer( 27 | target: self, action: #selector(ViewController.pan(recognizer:)) 28 | ) 29 | panLabel.addGestureRecognizer(panGestureRecognizer) 30 | } 31 | } 32 | ``` 33 | 34 | ### UIPanGestureRecognizer 35 | 36 | ```Swift 37 | // 返回手势积累量 38 | func translation(in view: UIView?) -> CGPoint 39 | // 重置 translation，为防止多次手势叠加，需最后重置为 CGPoint.zero 40 | func setTranslation(_ translation: CGPoint, in view: UIView?) 41 | // 手势拖动速度，单位 points/s 42 | func velocity(in view: UIView?) -> CGPoint 43 | ``` 44 | 45 | ### UIGestureRecognizerState 46 | 47 | - UIGestureRecognizerState 是手势状态的枚举。 48 | - 手势开始前：`.possible`。 49 | - 对于连续的手势：例如 pan（拖动），从 `.begin` 开始，重复 `.changed`，最后结束 `.ended`，状态有时会 `.failed` 或 `.cancelled`，需要特别注意。 50 | - 对于不连续的手势：例如 swipe（猛划）、tap（轻拍），没有中间过程，直接 `.ended` 或 `.recognized`。 51 | 52 | ```Swift 53 | func pan(recognizer: UIPanGestureRecognizer) { 54 | print("pan 手势状态枚举原始值：\(recognizer.state.rawValue)") 55 | 56 | switch recognizer.state { 57 | case .changed: fallthrough 58 | case .ended: 59 | let point = recognizer.translation(in: pannableLabel) 60 | let center = pannableLabel.center 61 | 62 | recognizer.view?.center = CGPoint(x: center.x + point.x, y: center.y) 63 | recognizer.setTranslation(CGPoint.zero, in: pannableLabel) 64 | default: 65 | break 66 | } 67 | } 68 | 69 | func tap(recognizer: UITapGestureRecognizer) { 70 | print("tap 手势状态枚举原始值：\(recognizer.state.rawValue)") 71 | } 72 | ``` 73 | 74 | ## MVC 75 | 76 | - 本节主要涉及了多 MVC 的场景，例如 UINavigationController，UITabbarController，以及 UISplitController。 77 | - UISplitController 主要为大屏设备使用，为适配小屏，需配合 UINavigationController 使用。 78 | - 本章内容使用文字表述过于复杂，未来可能整理至 Demo 中。 79 | 80 | ## Segue 81 | 82 | - Segue 即转场。 83 | 84 | ### Types 85 | 86 | - Show Segue: e.g. push 87 | - 从右向左进入，从左向右返回。 88 | - 嵌入 UINavigationController 时，头部自带返回按钮。 89 | - Show Detail Segue: e.g. replace 90 | - 从下向上进入，从上向下返回。 91 | - 嵌入 UISplitViewController 时，替换 DetailViewController，不带返回按钮。 92 | - Modally Segue 93 | - 由 Presentation 选项定义。 94 | - Popover Segue 95 | - Custom 96 | 97 | ### Identifier 98 | 99 | - Segue 总是创建一个新的 MVC 实例（不会重用）。 100 | - 使用代码调用 Segue `func performSegue(withIdentifier identifier: String, sender: Any?)`。 101 | 102 | ### Preparing 103 | 104 | - 以下方法的调用时机在 Outlet 链接前。 105 | 106 | ```Swift 107 | override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 108 | if let identifier = segue.identifier { 109 | switch identifier { 110 | case "Show Graph": 111 | if let vc = segue.destination as? GraphController { 112 | // Setup vc 113 | } 114 | default: 115 | break 116 | } 117 | } 118 | } 119 | ``` 120 | 121 | ### Preventing 122 | 123 | - 若要 UIViewController 阻止 Segue 发生，重写以下方法并返回 `false` 即可。 124 | 125 | ```Swift 126 | override func shouldPerformSegue(withIdentifier identifier: String, sender: Any?) -> Bool { 127 | return false 128 | } 129 | ``` 130 | 131 | ## Reference 132 | 133 | -

ARC: Automatic Reference Count 自动引用计数（!= Garbage Collection 垃圾回收） 24 | - 引用类型（例如类）存储在堆（Heap）中。 25 | 26 | ### strong 27 | 28 | - 「强」引用： 29 | - 默认的引用指针，可省略 30 | - 只要有强引用指针指向，对象将一直保存在堆中。 31 | 32 | ### weak 33 | 34 | - 「弱」引用： 35 | - 当对象没有被使用时，即被销毁（nil）。 36 | - 弱引用用于指向引用类型的可选类型指针。 37 | - 弱引用指针将不会把对象保存在堆中。 38 | - 例子： 39 | - outlets（其被视图层次强力持有，所以可为 weak）。 40 | 41 | ### unowned 42 | 43 | - 「不」持有： 44 | - 需确保指针指向的对象没有被销毁（离开堆），否则程序会崩溃。 45 | - 常只用于打破循环引用。 46 | 47 | ### Closures 48 | 49 | > 此处代码已更新至 [Calculator](https://github.com/kingcos/CS193P_2017/tree/master/Calculator)。 50 | 51 | - 闭包是引用类型，同样存储在堆区。 52 | - 闭包可以放在数组，字典等，是 Swift 的一等（first-class）类型。 53 | - 当作为参数的闭包，执行的时机超出其自身时，需声明为逃逸闭包，即在闭包参数前加 `@escaping`： 54 | 55 | ```Swift 56 | mutating func addUnaryOperation(named symbol: String, _ operation: @escaping (Double) -> Double) { 57 | operations[symbol] = Operation.unaryOperation(operation) 58 | } 59 | ``` 60 | 61 | - 逃逸尾随闭包的使用： 62 | 63 | ```Swift 64 | // 常规写法 65 | brain.addUnaryOperation(named: "✅") { (value) -> Double in 66 | return sqrt(value) 67 | } 68 | 69 | // 简写 70 | brain.addUnaryOperation(named: "✅") { 71 | return sqrt($0) 72 | } 73 | ``` 74 | 75 | - 只要闭包仍保留在堆中，那么其捕获的引用也仍在堆中。 76 | - 闭包中的循环引用： 77 | 78 | ```Swift 79 | // 此时模型和控制器在闭包中相互引用，构成循环引用 80 | brain.addUnaryOperation(named: "✅") { 81 | self.display.textColor = UIColor.green 82 | return sqrt($0) 83 | } 84 | ``` 85 | 86 | - 解决闭包中的循环引用的方法： 87 | 88 | - *weak* 89 | 90 | ```Swift 91 | brain.addUnaryOperation(named: "✅") { [weak self] in 92 | // self 为 Optional 93 | self?.display.textColor = UIColor.green 94 | return sqrt($0) 95 | } 96 | 97 | brain.addUnaryOperation(named: "✅") { [weak weakSelf = self] in 98 | weakSelf?.display.textColor = UIColor.green 99 | return sqrt($0) 100 | } 101 | ``` 102 | 103 | - *unowned* 104 | 105 | ```Swift 106 | brain.addUnaryOperation(named: "✅") { [me = self] in 107 | me.display.textColor = UIColor.green 108 | return sqrt($0) 109 | } 110 | 111 | brain.addUnaryOperation(named: "✅") { [unowned me = self] in 112 | me.display.textColor = UIColor.green 113 | return sqrt($0) 114 | } 115 | 116 | brain.addUnaryOperation(named: "✅") { [unowned self = self] in 117 | self.display.textColor = UIColor.green 118 | return sqrt($0) 119 | } 120 | 121 | brain.addUnaryOperation(named: "✅") { [unowned self] in 122 | self.display.textColor = UIColor.green 123 | return sqrt($0) 124 | } 125 | ``` 126 | 127 | ## Reference 128 | 129 | -

UITextField 是 iOS 中的文本输入控件，部分属性类似于 UILabel。 24 | - 当用户点击 UITextField 或发送 `becomeFirstResponder` 消息，即成为第一响应者（First Responder），软键盘随即显示；发送 `resignFirstResponder` 消息，则注销第一响应者，键盘随即消失。 25 | - 控制器若要代理 UITextField，需遵从 UITextFieldDelegate 协议，并通过 Storyboard 或代码设置代理，即可实现相应代理方法。 26 | - UITextField 也实现了 UIControl 协议，即遵守了 [Target-Action 设计模式](http://www.jianshu.com/p/b00056fac0a8)。 27 | 28 | ### Keyboard 29 | 30 | - 软键盘的属性定义在 UITextInputTraits 协议中，UITextField 实现了该协议，因此可以通过 UITextField 更改软件的属性。 31 | - 软键盘上方可以自定义视图，设置为 UITextField 的 `inputAccessoryView` 属性即可。 32 | - 软键盘弹出时，会覆盖在其他控件之上，为了良好的用户体验，UITextField 要保持可见（不能被覆盖）。 33 | - UITableViewController 会监听 UITextField，并当键盘弹出时，自动调整到该 UITextField 的一行，即 UITextField 不会被覆盖。 34 | - 可以通过 UIWindow 发出的 Notification（通知）来响应，当相应的事件发生时，注册的方法将会被调用。如下：`Notification.Name.UIKeyboardDidShow` 事件发生，selector 的方法即被调用。 35 | 36 | ```Swift 37 | // 通知 38 | NotificationCenter.default.addObserver(self, 39 | selector: #selector(keyboardAppeared(_:)), 40 | name: Notification.Name.UIKeyboardDidShow, 41 | object: view.window) 42 | 43 | func keyboardAppeared(_ notification: Notification) { 44 | // Do something... 45 | print("\(#function) -
