我剛經(jīng)歷了一場(chǎng)末日（停電），特別是在你想寫(xiě)文檔的時(shí)候。。。

言歸正傳，今天的問(wèn)題是解決iOS10系統(tǒng)下首次按鈕APP彈出的網(wǎng)絡(luò)權(quán)限提示所帶來(lái)了問(wèn)題以及優(yōu)化。

起因

查了相關(guān)文章知道由于大陸工信部出臺(tái)的新規(guī)指出，應(yīng)用在未經(jīng)用戶允許的前提下，系統(tǒng)不能授予其使用聯(lián)網(wǎng)、獲取定位的功能。Apple在iOS10系統(tǒng)中加入了關(guān)于應(yīng)用使用數(shù)據(jù)的授權(quán)彈窗提示，用戶在iOS系統(tǒng)及以上系統(tǒng)中第一次打開(kāi)應(yīng)用時(shí)，會(huì)被要求對(duì)于是否授予應(yīng)用聯(lián)網(wǎng)權(quán)限進(jìn)行選擇。

問(wèn)題

Apple把自己的問(wèn)題解決了， 但是Apple沒(méi)有給出官方的獲取選擇事件的回調(diào)，這樣就是給開(kāi)發(fā)者挖坑了。 對(duì)于很多開(kāi)發(fā)者習(xí)慣于把預(yù)加載接口放到AppDelegate的同志就很苦惱了。 這樣會(huì)造成配置接口請(qǐng)求失敗，首頁(yè)數(shù)據(jù)為空的情況，第一次獲取DeviceToken失敗，添加推送通知失敗，第三方初始化失敗，以至于導(dǎo)致很多延伸的問(wèn)題。

解決

1.根據(jù)CTCellularData類獲取網(wǎng)絡(luò)權(quán)限狀態(tài)以及監(jiān)聽(tīng)狀態(tài)改變回調(diào)（推薦）

我就在使用此方法。話不多說(shuō)上代碼，注釋很詳細(xì)； 添加CoreTelephony系統(tǒng)庫(kù)，在AppDelegate.m里#import<CoreTelephony/CTCellularData.h> [objc] view plain copy

-?(BOOL)application:(UIApplication?*)application?didFinishLaunchingWithOptions:(NSDictionary?*)launchOptions?{??

????//?Override?point?for?customization?after?application?launch.??

??????

????//1.獲取網(wǎng)絡(luò)權(quán)限?根絕權(quán)限進(jìn)行人機(jī)交互??

????????[self?networkStatus:application?didFinishLaunchingWithOptions:launchOptions];??

????}else?{??

????????//2.2已經(jīng)開(kāi)啟網(wǎng)絡(luò)權(quán)限?監(jiān)聽(tīng)網(wǎng)絡(luò)狀態(tài)??

????[self.window?setBackgroundColor:[UIColor?whiteColor]];??

????[self.window?makeKeyAndVisible];??

????return?YES;??

}??

這樣也同時(shí)解決了用戶如果選擇不允許和限制兩種情況，在用戶沒(méi)有統(tǒng)一聯(lián)網(wǎng)的情況下，APP會(huì)顯示沒(méi)有網(wǎng)絡(luò)的UI，重新進(jìn)入APP會(huì)調(diào)用在不允許狀態(tài)下會(huì)調(diào)用一個(gè)測(cè)試接口，APP會(huì)自動(dòng)彈出重新選擇網(wǎng)絡(luò)權(quán)限以及說(shuō)明的彈窗，進(jìn)入設(shè)置修改過(guò)APP聯(lián)網(wǎng)權(quán)限以后選擇回到APP就會(huì)觸發(fā)cellularDataRestrictionDidUpdateNotifier，在回調(diào)里進(jìn)行相應(yīng)的人機(jī)交互就可以了。

2.延遲請(qǐng)求

就是把配置請(qǐng)求放到首頁(yè)VC里，不要放到AppDelegate里，同時(shí)監(jiān)聽(tīng)網(wǎng)絡(luò)狀態(tài)(AF,其他第三方等）有個(gè)致命性的問(wèn)題就是獲取網(wǎng)絡(luò)狀態(tài)會(huì)有一定的延遲（親測(cè)），導(dǎo)致很多情況，還有就是要自己處理權(quán)限彈框以及對(duì)原有代碼邏輯要進(jìn)行修改。

總結(jié)

這個(gè)問(wèn)題遇到幾次了，原來(lái)都是用第二種方式進(jìn)行了一定的優(yōu)化，這次的APP有一個(gè)配置信息接口導(dǎo)致出現(xiàn)問(wèn)題，寫(xiě)下來(lái)作為記錄，方法還有很多種，不足的地方還有很多，僅供大家參考。
