macOS警告/提示視圖 — NSAlert、自定義WindowController

系統(tǒng)的NSAlert——系統(tǒng)自帶提示視圖

在'ViewController.swift'文件中，先創(chuàng)建一個(gè)NSAlert實(shí)例來看看~

import Cocoa

class ViewController: NSViewController {

    @objc func clickItem(btn: NSButton) {
        print("clickItem:\(btn.title)")
        
    }
    @objc func showNotice() {
        let alert = NSAlert()
        //添加的前3個(gè)項(xiàng)(按鈕)，會(huì)響應(yīng)‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法——且枚舉中有對(duì)應(yīng)項(xiàng)進(jìn)行確認(rèn)
        alert .addButton(withTitle: "確定")
        alert .addButton(withTitle: "取消")
        let item3 = alert .addButton(withTitle: "More") //獲取對(duì)應(yīng)的按鈕
        //item3.target = self; item3.action = #selector(clickItem)//重寫方法—覆蓋‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法
        //第4項(xiàng)(按鈕)開始，會(huì)響應(yīng)‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法——但枚舉中沒有對(duì)應(yīng)項(xiàng)進(jìn)行確認(rèn)
        let item4 = alert .addButton(withTitle: "第4項(xiàng)")  //獲取對(duì)應(yīng)的按鈕
        //item4.target = self; item4.action = #selector(clickItem)//重寫方法—覆蓋‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法
        let item5 = alert .addButton(withTitle: "第5項(xiàng)")  //獲取對(duì)應(yīng)的按鈕
        //item5.target = self; item5.action = #selector(clickItem)//重寫方法—覆蓋‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法
        alert.messageText = "blabla操作的警告"http://標(biāo)題
        alert.informativeText = "blabla操作會(huì)導(dǎo)致XX后果，是否繼續(xù)?"http://詳細(xì)描述
        //設(shè)置NSAlert的展示風(fēng)格
        alert.alertStyle = NSAlert.Style.critical//warning\informational\critical
        alert .beginSheetModal(for: self.view .window!) { (returnCode: NSApplication.ModalResponse) in
            //點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)
            switch returnCode {
            case .alertFirstButtonReturn:
                print("NSApplication.ModalResponse.alertFirstButtonReturn")
            case .alertSecondButtonReturn:
                print("NSApplication.ModalResponse.alertSecondButtonReturn")
            case .alertThirdButtonReturn:
                print("NSApplication.ModalResponse.alertThirdButtonReturn")
            //以下條件均不會(huì)到達(dá)
            case .stop:
                print("NSApplication.ModalResponse.stop")
            case .abort:
                print("NSApplication.ModalResponse.abort")
            case .`continue`:
                print("NSApplication.ModalResponse.`continue`")
            case .OK:
                print("NSApplication.ModalResponse.OK")
            case .cancel:
                print("NSApplication.ModalResponse.cancel")
            case .continue:
                print("NSApplication.ModalResponse.continue")
            default:
                print("Other situation——default")
                break
            }
        }
        
    }
    func addOneBtn() {//為該window，隨便添加一個(gè)按鈕
        let btn = NSButton(frame: NSMakeRect(100, 100, 100, 100))
        btn.target = self; btn.action = #selector(showNotice)
        self.view .addSubview(btn)
    }
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        self .addOneBtn()//添加按鈕
        
    }

    override var representedObject: Any? {
        didSet {
        // Update the view, if already loaded.
        }
    }


}

效果：
1.點(diǎn)擊'Button'按鈕后彈出NSAlert視圖！彈出該NSAlert視圖后(除了該NSAlert視圖 可進(jìn)行選擇)其他的視圖 不能進(jìn)行操作~
2.前3項(xiàng)(按鈕)——點(diǎn)擊第1項(xiàng)('確定')/第2項(xiàng)('取消')/第3項(xiàng)('More')后NSAlert視圖會(huì)消失并打印NSApplication.ModalResponse.alertFirstButtonReturn/NSApplication.ModalResponse.alertSecondButtonReturn/NSApplication.ModalResponse.alertThirdButtonReturn！
3.從第4項(xiàng)(按鈕)開始，點(diǎn)擊第4項(xiàng)('第4項(xiàng)')/第5項(xiàng)('第5項(xiàng)')后NSAlert視圖會(huì)消失并都打印Other situation——default！

結(jié)論：添加的前3個(gè)項(xiàng)(按鈕)，會(huì)響應(yīng)‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法——且枚舉中有對(duì)應(yīng)項(xiàng)進(jìn)行確認(rèn)！第4項(xiàng)(按鈕)開始，會(huì)響應(yīng)‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法——但枚舉中沒有對(duì)應(yīng)項(xiàng)進(jìn)行確認(rèn)！

Tips：可通過open func addButton(withTitle title: String) -> NSButton方法，獲取該項(xiàng)對(duì)應(yīng)的按鈕！對(duì)其按鈕重寫方法—覆蓋‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法后，點(diǎn)擊該項(xiàng)后NSAlert視圖不會(huì)消失（不會(huì)走系統(tǒng)默認(rèn)‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法而是執(zhí)行@objc func clickItem(btn: NSButton)方法）！

公開注釋后的@objc func showNotice()方法：

@objc func showNotice() {
   let alert = NSAlert()
    //添加的前3個(gè)項(xiàng)(按鈕)，會(huì)響應(yīng)‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法——且枚舉中有對(duì)應(yīng)項(xiàng)進(jìn)行確認(rèn)
    alert .addButton(withTitle: "確定")
    alert .addButton(withTitle: "取消")
    let item3 = alert .addButton(withTitle: "More") //獲取對(duì)應(yīng)的按鈕
    item3.target = self; item3.action = #selector(clickItem)//重寫方法—覆蓋‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法
    //第4項(xiàng)(按鈕)開始，會(huì)響應(yīng)‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法——但枚舉中沒有對(duì)應(yīng)項(xiàng)進(jìn)行確認(rèn)
    let item4 = alert .addButton(withTitle: "第4項(xiàng)")  //獲取對(duì)應(yīng)的按鈕
    item4.target = self; item4.action = #selector(clickItem)//重寫方法—覆蓋‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法
   let item5 = alert .addButton(withTitle: "第5項(xiàng)")  //獲取對(duì)應(yīng)的按鈕
    item5.target = self; item5.action = #selector(clickItem)//重寫方法—覆蓋‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法
    alert.messageText = "blabla操作的警告"http://標(biāo)題
    alert.informativeText = "blabla操作會(huì)導(dǎo)致XX后果，是否繼續(xù)?"http://詳細(xì)描述
    //設(shè)置NSAlert的展示風(fēng)格
    alert.alertStyle = NSAlert.Style.critical//warning\informational\critical
    alert .beginSheetModal(for: self.view .window!) { (returnCode: NSApplication.ModalResponse) in
        //點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)
        switch returnCode {
        case .alertFirstButtonReturn:
            print("NSApplication.ModalResponse.alertFirstButtonReturn")
        case .alertSecondButtonReturn:
            print("NSApplication.ModalResponse.alertSecondButtonReturn")
        case .alertThirdButtonReturn:
            print("NSApplication.ModalResponse.alertThirdButtonReturn")
        //以下條件均不會(huì)到達(dá)
        case .stop:
            print("NSApplication.ModalResponse.stop")
        case .abort:
            print("NSApplication.ModalResponse.abort")
        case .`continue`:
            print("NSApplication.ModalResponse.`continue`")
        case .OK:
            print("NSApplication.ModalResponse.OK")
        case .cancel:
            print("NSApplication.ModalResponse.cancel")
        case .continue:
            print("NSApplication.ModalResponse.continue")
        default:
            print("Other situation——default")
            break
        }
    }
    
}

該項(xiàng)對(duì)應(yīng)按鈕的點(diǎn)擊回調(diào)方法：

@objc func clickItem(btn: NSButton) {
    print("clickItem:\(btn.title)")
    
}

效果：
1.點(diǎn)擊'Button'按鈕后彈出NSAlert視圖！彈出該NSAlert視圖后(除了該NSAlert視圖 可進(jìn)行選擇)其他的視圖 不能進(jìn)行操作~
2.前2項(xiàng)(按鈕)——點(diǎn)擊第1項(xiàng)('確定')/第2項(xiàng)('取消')/后NSAlert視圖會(huì)消失并打印NSApplication.ModalResponse.alertFirstButtonReturn/NSApplication.ModalResponse.alertSecondButtonReturn/NSApplication.ModalResponse.alertThirdButtonReturn！
3.從第3項(xiàng)(按鈕)開始—對(duì)應(yīng)按鈕添加了action響應(yīng)，點(diǎn)擊第3項(xiàng)('More')/第4項(xiàng)('第4項(xiàng)')/第5項(xiàng)('第5項(xiàng)')后NSAlert視圖均不會(huì)消失（不會(huì)走系統(tǒng)默認(rèn)‘點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)’方法）并執(zhí)行@objc func clickItem(btn: NSButton)方法后分別打印clickItem:More/clickItem:第4項(xiàng)/clickItem:第5項(xiàng)！


NSAlert的alertStyle屬性對(duì)應(yīng)的效果——NSAlert.Style.warning、NSAlert.Style.informational、NSAlert.Style.critical

NSAlert.Style.warning
NSAlert.Style.informational
NSAlert.Style.critical

由上面代碼可以發(fā)現(xiàn)NSAlert實(shí)例對(duì)象是基于NSWindow對(duì)象來創(chuàng)建的！
所以代碼如下：為NSWindow類添加擴(kuò)展(extension)~

 extension NSWindow {
    //創(chuàng)建macOS警告/提示視圖——返回NSApplication.ModalResponse
    public func showAlertNotice(firstItemStr: String, secondItemStr: String, title: String, information: String, alertStyle: NSAlert.Style, completionHalder handler: @escaping ((NSApplication.ModalResponse) -> Void)) {//@escaping——去除“scaping closure captures non-escaping parameter 'handler'”警告
        let alert = NSAlert()
        alert .addButton(withTitle: firstItemStr)
        alert .addButton(withTitle: secondItemStr)
        alert.messageText = title//標(biāo)題
        alert.informativeText = information//詳細(xì)描述
        //設(shè)置NSAlert的展示風(fēng)格
        alert.alertStyle = alertStyle//warning\informational\critical
        alert .beginSheetModal(for: self) { (returnCode: NSApplication.ModalResponse) in
            //點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)
            handler(returnCode)
        }
    }
    //創(chuàng)建macOS警告/提示視圖——返回bool值
    public func showAlertNoticeWithBool(firstItemStr: String, secondItemStr: String, title: String, information: String, alertStyle: NSAlert.Style, completionHalder handler: @escaping ((Bool) -> Void)) {//@escaping——去除“scaping closure captures non-escaping parameter 'handler'”警告
        let alert = NSAlert()
        alert .addButton(withTitle: firstItemStr)
        alert .addButton(withTitle: secondItemStr)
        alert.messageText = title//標(biāo)題
        alert.informativeText = information//詳細(xì)描述
        //設(shè)置NSAlert的展示風(fēng)格
        alert.alertStyle = alertStyle//warning\informational\critical
        alert .beginSheetModal(for: self) { (returnCode: NSApplication.ModalResponse) in
            //點(diǎn)擊選項(xiàng)時(shí)系統(tǒng)的回調(diào)
            if returnCode == .alertFirstButtonReturn {//點(diǎn)擊"確定"
                handler(true)
            } else if returnCode == .alertSecondButtonReturn {//點(diǎn)擊"取消"
                handler(false)
            }
        }
        
    }
}

方法的調(diào)用：在'ViewController.swift'文件中

//返回NSApplication.ModalResponse
self.view.window! .showAlertNotice(firstItemStr: "OK", secondItemStr: "取消", title: "標(biāo)題", information: "警告的提示內(nèi)容和信息", alertStyle: .critical) { (returnCode : NSApplication.ModalResponse) in
    if returnCode == .alertFirstButtonReturn {//點(diǎn)擊"確定"
        print("returnCode == .alertFirstButtonReturn")
        //"確定"相應(yīng)的操作
    } else if returnCode == .alertSecondButtonReturn {//點(diǎn)擊"取消"
        print("returnCode == .alertSecondButtonReturn")
        //"取消"相應(yīng)的操作
    }
}

//返回bool值
self.view.window! .showAlertNoticeWithBool(firstItemStr: "OK", secondItemStr: "取消", title: "標(biāo)題", information: "警告的提示內(nèi)容和信息", alertStyle: .critical) { (isOK: Bool) in
    if isOK == true {//點(diǎn)擊"確定"
        print("isOK == true")
        //"確定"相應(yīng)的操作
    } else {//點(diǎn)擊"取消"
        print("isOK == false")
        //"取消"相應(yīng)的操作
    }
}


自定義WindowController

新建一個(gè)自定義的GYHNoticeAlertWindowController類（需勾選'Also create XIB file for user interface'）

勾選'Also create XIB file for user interface'

添加的圖片素材：

    }
    
}

在'ViewController.swift'文件中，進(jìn)行使用：

import Cocoa

class ViewController: NSViewController, NSWindowDelegate {
    
    var noticeWC: GYHNoticeAlertWindowController?//自定義‘提示’窗口
    //事件的響應(yīng)——自定義‘提示’窗口
    @objc func clickWindowButton(btn: NSButton) {
        btn.state = NSControl.StateValue.off//改為‘關(guān)閉’狀態(tài)——非選中
        
        if btn == noticeWC?.sureBtn {//點(diǎn)擊"確定"
            print("btn == noticeWC?.sureBtn")
            //"確定"相應(yīng)的操作
            
            //關(guān)閉模態(tài)、關(guān)閉窗口
            NSApplication .shared .stopModal()
            self .dismissNotice()
        } else if btn == noticeWC?.cancelBtn {//點(diǎn)擊"取消"
            print("btn == noticeWC?.cancelBtn")
            //"取消"相應(yīng)的操作
            
            //關(guān)閉模態(tài)、關(guān)閉窗口
            NSApplication .shared .stopModal()
            self .dismissNotice()
        }
    }
    //創(chuàng)建并展示‘提示’窗口
    public func createShowNotice(with delegate: NSWindowDelegate?) {
        //判空，避免重復(fù)創(chuàng)建
        noticeWC = noticeWC != nil ? noticeWC : GYHNoticeAlertWindowController(title: nil, message: nil, backColor:nil, okStr: nil, cancelStr: nil)//自定義初始化方法
        noticeWC? .showWindow(nil)
        //if delegate != nil {
        //    noticeWC?.window?.delegate = delegate;
        //} //無需delegate
        noticeWC?.sureBtn?.target = self;   noticeWC?.sureBtn?.action = #selector(clickWindowButton)
        noticeWC?.cancelBtn?.target = self; noticeWC?.cancelBtn?.action = #selector(clickWindowButton)
        
        //開啟模態(tài)
        NSApplication .shared .runModal(for: (noticeWC?.window)!)
    }
    //隱藏‘提示’窗口
    public func dismissNotice() {
        noticeWC? .close()//關(guān)閉窗口
        //noticeWC?.window?.delegate = nil  //無需delegate
        noticeWC = nil//置為nil
    }
    
    @objc func showNotice() {
        self .createShowNotice(with: nil)
    }

    func addOneBtn() {//為該window，隨便添加一個(gè)按鈕
        let btn = NSButton(frame: NSMakeRect(100, 100, 100, 100))
        btn.target = self; btn.action = #selector(showNotice)
        self.view .addSubview(btn)
    }
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        self .addOneBtn()//添加按鈕
        
    }
        
    override var representedObject: Any? {
        didSet {
        // Update the view, if already loaded.
        }
    }


}

效果：
1.點(diǎn)擊'Button'按鈕后彈出自定義‘提示’窗口（GYHNoticeAlertWindowController窗口）！彈出該GYHNoticeAlertWindowController窗口后(除了該GYHNoticeAlertWindowController窗口 可進(jìn)行選擇)其他的視圖 不能進(jìn)行操作~
2.點(diǎn)擊'確定'/'取消'后該GYHNoticeAlertWindowController窗口會(huì)消失并進(jìn)行其相應(yīng)的打印！之后其他的視圖 可以進(jìn)行操作~

在"Debug View hierarchy"中查看視圖層次：

1.系統(tǒng)默認(rèn)自帶的窗口（'NSWindowController'）：

NSWindowController


2.自定義‘提示’窗口（'GYHNoticeAlertWindowController'）：

GYHNoticeAlertWindowController


思路如此，封裝看個(gè)人~（不想去封裝了??）


Tip1：關(guān)于按鈕字體居中、顏色、大小，可參考《NSButton的使用（Mac端 按鈕）》中“設(shè)置按鈕的標(biāo)題顏色及字體”部分：
其中“-(void)setTitleColorToColor:(NSColor *)color andFontNum:(CGFloat)FontNum isBold:(BOOL)isBold;”方法通過了設(shè)置按鈕的attributedTitle屬性(富文本)中使用[paraStyle setAlignment:NSTextAlignmentCenter];實(shí)現(xiàn)了字體居中~

Tip2：關(guān)于提示信息Label的文字可能超出了控件范圍的問題：

  • 1.可以設(shè)置其toolTip屬性—鼠標(biāo)放置上去就會(huì)展示出來！（效果如下）


不想再寫份Swift的代碼~??

Tip3：解決“頂部標(biāo)題欄鼠標(biāo)不能拖動(dòng)、邊框不圓滑”的問題

將

self.window?.styleMask = NSWindow.StyleMask.fullSizeContentView//窗口風(fēng)格：頂部視圖+窗口(融合)

替換為如下代碼：

self.window?.styleMask = [self.window!.styleMask, >NSWindow.StyleMask.fullSizeContentView]//窗口風(fēng)格：圓滑邊框、頂部視圖+窗口(融合)
//獲取 (系統(tǒng))左側(cè)的‘關(guān)閉’、‘最小化’、‘最大化’按鈕
let closeBtn = self.window?.standardWindowButton(NSWindow.ButtonType.closeButton)
let zoomBtn = self.window?.standardWindowButton(NSWindow.ButtonType.zoomButton)
let miniaturizeBtn = self.window?.standardWindowButton(NSWindow.ButtonType.miniaturizeButton)
closeBtn?.isHidden = true       //隱藏 ‘關(guān)閉’按鈕     //初始位置 X:7.0   Y:3.0
zoomBtn?.isHidden = true        //隱藏 ‘最大化’按鈕     //初始位置 X:47.0   Y:3.0
miniaturizeBtn?.isHidden = true //隱藏 ‘最小化’按鈕   //初始位置 X:27.0   Y:3.0

優(yōu)化后的效果：頂部標(biāo)題欄鼠標(biāo)可以拖動(dòng)、邊框圓滑
