WWDC2016,Apple發(fā)布了ios10撇簿，每次版本發(fā)布擒抛，都會(huì)帶來(lái)新的接口推汽，新的機(jī)會(huì)，也能間接的看到Apple的未來(lái)發(fā)展方向歧沪。

這里就不討論iphone7歹撒、MacBook Pro、Apple Watch诊胞、Apple TV以及AirPods了暖夭。

下面回顧一下，Apple今年為我們帶來(lái)了什么

一撵孤，一些限制

IPV6

HTTPS

1.IPV6

由于IPv4最大的問(wèn)題在于網(wǎng)絡(luò)地址資源有限迈着，嚴(yán)重制約了互聯(lián)網(wǎng)的應(yīng)用和發(fā)展。IPv6的使用邪码，不僅能解決網(wǎng)絡(luò)地址資源數(shù)量的問(wèn)題裕菠，而且也解決了多種接入設(shè)備連入互聯(lián)網(wǎng)的障礙

6月1號(hào)以后提交新版本需要支持IPV6-Only的網(wǎng)絡(luò)

與IPv4地址空間需要擴(kuò)充迫在眉睫,越來(lái)越多的企業(yè)和移動(dòng)電話運(yùn)營(yíng)商部署IPv6 DNS64和NAT64網(wǎng)絡(luò)。DNS64 / NAT64網(wǎng)絡(luò)是一種能使ipv6網(wǎng)絡(luò)闭专。取決于應(yīng)用程序的性質(zhì),過(guò)渡有不同的含義:如果您正在編寫(xiě)一個(gè)客戶端應(yīng)用程序使用高級(jí)網(wǎng)絡(luò)api,如NSURLSession和CFNetwork框架,你應(yīng)該不需要改變?nèi)魏螙|西為您的應(yīng)用程序使用IPv6地址奴潘。如果項(xiàng)目中用了老的AFNetworking或ASIHTTPRequest等第三方網(wǎng)絡(luò)請(qǐng)求框架則可能需要做一下適配。因?yàn)橛岸ぃO(píng)果審核是不會(huì)讓你過(guò)得画髓。

客戶端向服務(wù)器端請(qǐng)求域名解析，首先通過(guò)DNS64 Server查詢IPv6的地址平委，如果查詢不到奈虾，再向DNS Server查詢IPv4地址，通過(guò)DNS64 Server合成一個(gè)IPV6的地址廉赔，最終將一個(gè)IPV6的地址返回給客戶端

關(guān)于IPV6的詳細(xì)介紹請(qǐng)見(jiàn)：
IPV6

2.HTTPS
前面一個(gè)大神已經(jīng)詳細(xì)得介紹了HTTPS的相關(guān)知識(shí)肉微，講得非常詳細(xì)，大家想看的話可以回顧一下蜡塌。我在這也就不做過(guò)多贅述了碉纳。
HTTPS

• 2017年1月1日起，蘋(píng)果App Store中的所有App都必須啟用 App Transport Security(ATS)安全功能岗照。(但延期了)

"應(yīng)用傳輸安全協(xié)議是與iOS9和OS X 10.11一同發(fā)布的村象，該協(xié)議需要應(yīng)用程序通過(guò)HTTPS使用安全的網(wǎng)絡(luò)連接笆环，以提高用戶的數(shù)據(jù)和隱私安全攒至。
在2016年WWDC上我們宣布在今年年底之前，提交到App Store的應(yīng)用程序必須支持應(yīng)用傳輸安全協(xié)議躁劣。為了給你們充裕的時(shí)間去準(zhǔn)備迫吐，這個(gè)截止日期已被延長(zhǎng)，當(dāng)新的截止日期確定的時(shí)候账忘，我們將及時(shí)提供相關(guān)信息志膀。"

• App Transport Security(應(yīng)用程序安全傳輸)熙宇，簡(jiǎn)稱(chēng) ATS，是蘋(píng)果在 iOS 9 中首次推出的一項(xiàng)隱私安全保護(hù)功能溉浙，啟用ATS后烫止，它會(huì)屏蔽明文HTTP資源加載，強(qiáng)制App通過(guò)HTTPS連接網(wǎng)絡(luò)服務(wù)戳稽，通過(guò)傳輸加密保障用戶數(shù)據(jù)安全馆蠕。
• ATS要求服務(wù)器必須支持傳輸層安全(TLS)協(xié)議1.2以上版本;證書(shū)必須使用SHA256或更高的哈希算法簽名;必須使用2048位以上RSA密鑰或256位以上ECC算法等等，不滿足條件的證書(shū)惊奇，ATS都會(huì)拒絕連接互躬。強(qiáng)制開(kāi)啟ATS體現(xiàn)了蘋(píng)果一貫的隱私保護(hù)態(tài)度。 開(kāi)發(fā)者需要HTTPS證書(shū)颂郎。

二吼渡，ios10

IMessage

SiriKit

Speech Recognition

User Notifications

Others

1.IMessage
IMessage獲得重大更新，提供消息氣泡框效果乓序，手寫(xiě)信息寺酪。同時(shí)內(nèi)置的emoji表情也得到優(yōu)化，除了圖片變大3倍外竭缝，還能將文字直接轉(zhuǎn)化成emoji表情房维。蘋(píng)果還特別為IMessage開(kāi)辟了應(yīng)用專(zhuān)區(qū)，所以你也可以做IMessage App了抬纸。

使用Messages framework創(chuàng)建兩種類(lèi)型的app extensions：
Sticker packs
IMessage apps
第一種方式僅僅提供靜態(tài)的貼紙,貼紙包圖片,用戶可以發(fā)送內(nèi)聯(lián)消息附加到消息氣泡中咙俩。貼紙包不需要任何代碼。你添加標(biāo)簽圖像文件拖到貼紙包文件夾內(nèi)的貼紙資源目錄湿故。有效的圖像文件必須符合以下規(guī)格:

• 圖片必須是png阿趁、apng、gif坛猪、jpeg中的一種
• 圖片必須小于500k
• 為了效果好脖阵，圖像不應(yīng)少于100×100pt,或超過(guò)206×206pt
  如果你想做這些事的時(shí)候你就要用到第二種方式了

Use iMessage apps to:

• Present a custom user interface inside the Messages app; see MSMessagesAppViewController.
• Create a custom or dynamic sticker browser; see MSStickerBrowserViewController.
• Insert text, stickers, or media files into the Messages app’s input field; see MSConversation.
• Create interactive messages that carry app-specific data; see MSMessage.
• Update interactive messages (for example, to create games or collaborative apps); see MSSession.

//example1作為一個(gè)貼紙瀏覽器

class MessagesViewController: MSMessagesAppViewController, MSStickerBrowserViewDataSource {
var stickers = [MSSticker]()
func loadStickers() {
for i in 1...2 {
if let url = Bundle.main.url(forResource: "Sticker \(i)", withExtension: "png"){
 do {
    let sticker = try MSSticker(contentsOfFileURL: url, localizedDescription: "")
    stickers.append(sticker)
    } catch {
    print(error)
    }
   }
 }
}
func createStickerBrowser() {
    let controller = MSStickerBrowserViewController(stickerSize: .large)
    
    addChildViewController(controller)
    view.addSubview(controller.view)
    
    controller.stickerBrowserView.backgroundColor = UIColor.purple
    controller.stickerBrowserView.dataSource = self
    
    view.topAnchor.constraint(equalTo: controller.view.topAnchor).isActive = true
    view.bottomAnchor.constraint(equalTo: controller.view.bottomAnchor).isActive = true
    view.leftAnchor.constraint(equalTo: controller.view.leftAnchor).isActive = true
    view.rightAnchor.constraint(equalTo: controller.view.rightAnchor).isActive = true
}

func numberOfStickers(in stickerBrowserView: MSStickerBrowserView) -> Int {
  return stickers.count
}

func stickerBrowserView(_ stickerBrowserView: MSStickerBrowserView, stickerAt index: Int) -> MSSticker {
  return stickers[index]
}

override func viewDidLoad() {
    super.viewDidLoad()
    loadStickers()
    createStickerBrowser()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

// MARK: - Conversation Handling
    override func willBecomeActive(with conversation: MSConversation) {
    }
    override func didResignActive(with conversation: MSConversation) {
    }
    override func didReceive(_ message: MSMessage, conversation: MSConversation) {
    }
    override func didStartSending(_ message: MSMessage, conversation: MSConversation) {
    }
    override func didCancelSending(_ message: MSMessage, conversation: MSConversation) {
    }
    override func willTransition(to presentationStyle: MSMessagesAppPresentationStyle) {
    }
    override func didTransition(to presentationStyle: MSMessagesAppPresentationStyle) {
    }
}

example2(交互式)

class MessagesViewController: MSMessagesAppViewController {

@IBOutlet weak var stepper: UIStepper!

@IBAction func didPress(button sender: AnyObject) {
if let image = createImageForMessage(), let conversation = activeConversation {
    let layout = MSMessageTemplateLayout()
    layout.image = image
    layout.caption = "云萊塢"
    
    let message = MSMessage()
    message.layout = layout
    message.url = URL(string: "http://www.yunlaiwu.com/")
    
    conversation.insert(message, completionHandler: { (error) in
      print(error ?? "no error")
    })
   }
}

func createImageForMessage() -> UIImage? {
    let background = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 300))
    background.backgroundColor = UIColor.white
    
    let label = UILabel(frame: CGRect(x: 75, y: 75, width: 150, height: 150))
    label.font = UIFont.systemFont(ofSize: 56.0)
    label.backgroundColor = UIColor.red
    label.textColor = UIColor.white
    label.text = "\(Int(stepper.value))"
    label.textAlignment = .center
    label.layer.cornerRadius = label.frame.size.width/2.0
    label.clipsToBounds = true
    
    let imageView = UIImageView(frame: CGRect(x: 0, y: 200, width: 300, height: 100))

    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    
    background.removeFromSuperview()
    
    return image
}

2.SiriKit
Apple 為我們開(kāi)放了兩個(gè)framework讓我們更好的接入Siri
Intents、IntentsUI
Intents框架是必須支持的墅茉，支持基本應(yīng)用程序和系統(tǒng)之間的通信命黔。
IntentsUI框架是可選的，他提供了任務(wù)成功操作后的自定義UI接口就斤。

它所包括的領(lǐng)域：

• VoIP calling
• Messaging
• Payments
• Photo
• Workouts
• Ride booking
• CarPlay (automotive vendors only)
• Restaurant reservations (requires additional support from Apple)

接入siri的注意事項(xiàng)：

• 證書(shū)支持

• plist文件支持你所要的操作事件

import Intents

// As an example, this class is set up to handle Message intents.
// You will want to replace this or add other intents as appropriate.
// The intents you wish to handle must be declared in the extension's Info.plist.

// You can test your example integration by saying things to Siri like:
// "Send a message using <myApp>"
// "<myApp> John saying hello"
// "Search for messages in <myApp>"

class IntentHandler: INExtension, INSendMessageIntentHandling, INSearchForMessagesIntentHandling, INSetMessageAttributeIntentHandling {

override func handler(for intent: INIntent) -> Any {
    // This is the default implementation.  If you want different objects to handle different intents,
    // you can override this and return the handler you want for that particular intent.
    return self

// MARK: - INSendMessageIntentHandling

// Implement resolution methods to provide additional information about your intent (optional).
func resolveRecipients(forSendMessage intent: INSendMessageIntent, with completion: @escaping ([INPersonResolutionResult]) -> Void) {
    if let recipients = intent.recipients {

    resolutionResults += [INPersonResolutionResult.disambiguation(with: matchingContacts)]
    
    case 1:
    // We have exactly one matching contact
    resolutionResults += [INPersonResolutionResult.success(with: recipient)]
    
    case 0:
    // We have no contacts matching the description provided

3.Speech Recognition

語(yǔ)音識(shí)別技術(shù)原理

iOS 10引入了一個(gè)新的API,支持連續(xù)語(yǔ)音識(shí)別悍募，可以將識(shí)別語(yǔ)音轉(zhuǎn)錄成文本⊙蠡可以執(zhí)行語(yǔ)音實(shí)時(shí)轉(zhuǎn)錄和記錄音頻坠宴。

SpeechFramework框架中的重要類(lèi)

SFSpeechRecognizer：這個(gè)類(lèi)是語(yǔ)音識(shí)別的操作類(lèi)，用于語(yǔ)音識(shí)別用戶權(quán)限的申請(qǐng)绷旗，語(yǔ)言環(huán)境的設(shè)置喜鼓，語(yǔ)音模式的設(shè)置以及向Apple服務(wù)發(fā)送語(yǔ)音識(shí)別的請(qǐng)求副砍。
SFSpeechRecognitionTask：這個(gè)類(lèi)是語(yǔ)音識(shí)別服務(wù)請(qǐng)求任務(wù)類(lèi)，每一個(gè)語(yǔ)音識(shí)別請(qǐng)求都可以抽象為一個(gè)SFSpeechRecognitionTask實(shí)例庄岖，其中SFSpeechRecognitionTaskDelegate協(xié)議中約定了許多請(qǐng)求任務(wù)過(guò)程中的監(jiān)聽(tīng)方法豁翎。
SFSpeechRecognitionRequest:語(yǔ)音識(shí)別請(qǐng)求類(lèi)，需要通過(guò)其子類(lèi)來(lái)進(jìn)行實(shí)例化隅忿。
SFSpeechURLRecognitionRequest：通過(guò)音頻URL來(lái)創(chuàng)建語(yǔ)音識(shí)別請(qǐng)求谨垃。
SFSpeechAudioBufferRecognitionRequest:通過(guò)音頻流來(lái)創(chuàng)建語(yǔ)音識(shí)別請(qǐng)求。
SFSpeechRecognitionResult：語(yǔ)音識(shí)別請(qǐng)求結(jié)果類(lèi)硼控。
SFTranscription：語(yǔ)音轉(zhuǎn)換后的信息類(lèi)刘陶。

當(dāng)然，首先為了安全你得到plist文件中加權(quán)限

SFSpeechRecognizer.requestAuthorization { authStatus in
    if authStatus == SFSpeechRecognizerAuthorizationStatus.authorized {
        if let path = Bundle.main.url(forResource: "PPAP", withExtension: ".mp3") {
            let recognizer = SFSpeechRecognizer()
                let request = SFSpeechURLRecognitionRequest(url: path)
                    recognizer?.recognitionTask(with: request, resultHandler: { (result, error) in
                if let error = error {
                   print("There was an error: \(error)")
                } else {
                   print(result?.bestTranscription.formattedString)
                }
            })
        }
    }
}

4.User Notifications
支持了很多用戶定義的通知牢撼，并且可以捕捉到各個(gè)通知狀態(tài)的回調(diào)匙隔。以往的通知是大家想接收的都提前做好準(zhǔn)備，然后一下全量分發(fā)熏版，沒(méi)收到也不管了纷责，也不關(guān)心發(fā)送者。現(xiàn)在用戶通知做成了和網(wǎng)絡(luò)請(qǐng)求有點(diǎn)像撼短，一個(gè)request,response的流程再膳，也支持了error處理，可以在各個(gè)狀態(tài)的方法中做一些額外操作曲横，并且也能取到一些字段喂柒，如發(fā)送者等。
更為重要的是禾嫉，新增了UserNotificationsUI.framework框架灾杰，在收到通知的時(shí)候，可自定義通知UI樣式

let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert,.badge,.sound]) { (granted, error) in
    if granted {
        print("授權(quán)成功")
    }else{
        print("授權(quán)失敗")
    }
}

let content = UNMutableNotificationContent()
content.title = "云萊塢 PPAP"
content.body = "I have a pen I have an apple"
content.subtitle = "have a pineapple"
content.sound = UNNotificationSound.default()

let trigger1 = UNTimeIntervalNotificationTrigger(timeInterval: 61, repeats: true)

let request = UNNotificationRequest(identifier: "notificationTest", content: content, trigger:trigger1)

UNUserNotificationCenter.current().add(request) { (error) in
    if (error != nil) {
        print(error?.localizedDescription)
    }
}
