更新CocoaPods碰到的問題及知識點

1：解決CocoaPods安裝時報的問題，http://ruby.taobao.org/latest_specs.4.8.gz 報404

解決 bad response Not Found 404 (http://ruby.taobao.org/latest_specs.4.8.gz)

原因：淘寶停止基於 HTTP 協議的鏡像服務 需要改用https的協議

gem sources --remove http://ruby.taobao.org/

gem sources -a https://ruby.taobao.org/

gem sources -l

sudo gem install -n /usr/local/bin cocoapods

當然如果你是第一次安裝時（目前網上有些安裝資料可能還指向淘寶的http）：

gem sources -l
gem sources --remove https://rubygems.org/
gem sources -a https://ruby.taobao.org/
gem sources -l
sudo gem install -n /usr/local/bin cocoapods

2:CocoaPods更新版本後，安裝跟更新第三方報錯

可以通過 $ pod --version 查看版本號；

原因是podfile升級到最新版本，pod里的內容必須明確指出所用第三方庫的target；可以修改Podfile文件的配置文件，讓它相容不指定固定版本；且又不報錯；

platform :ios, '7.0'

target 'zxptUser’ do

pod 'ReactiveCocoa', '~> 2.5'
pod 'SDWebImage', '~> 3.7.5'
pod 'AFNetworking', '~> 2.5.4'
pod 'Masonry', '~> 0.6.4'
pod 'JSONModel', '~> 1.2.0'
pod 'JCAlertView', '~> 1.1.5'
pod 'RongCloudIMKit', '2.5.2' #不要更新此庫 源代碼已被修改
pod 'SMPageControl', '~> 1.2'
pod 'FMDB'
pod 'GTSDK'
pod 'BaiduMapKit' #百度地圖SDK
pod 'UMengAnalytics-NO-IDFA'#友盟統計無IDFA版SDK
pod 'Fabric'
pod 'Crashlytics'
pod 'CocoaLumberjack'
pod 'TTTAttributedLabel'
pod 'FLEX'
pod 'GVUserDefaults'
pod 'UMengFeedback', '~> 2.3.4'
pod 'TYAttributedLabel', '~> 2.5.6’
pod 'IQKeyboardManager'
pod 'MWPhotoBrowser'

end

其中zxptUser要換成當前target名，最後不要忘記增加一個end結尾,當然如果你的工程是有多個target都要引用；則要使用link_with（這個一定要放在文件第一行）如下：

link_with ['zxptUser' ,'zxptUser_local', 'zxptUser_AppStore']
platform :ios, '7.0'
pod 'ReactiveCocoa', '~> 2.5'
pod 'SDWebImage', '~> 3.7.5'
pod 'AFNetworking', '~> 2.5.4'
pod 'Masonry', '~> 0.6.4'
pod 'JSONModel', '~> 1.2.0'
pod 'JCAlertView', '~> 1.1.5'
pod 'RongCloudIMKit', '2.5.2' #不要更新此庫 源代碼已被修改
pod 'SMPageControl', '~> 1.2'
pod 'FMDB'
pod 'GTSDK'
pod 'BaiduMapKit' #百度地圖SDK
pod 'UMengAnalytics-NO-IDFA'#友盟統計無IDFA版SDK
pod 'Fabric'
pod 'Crashlytics'
pod 'CocoaLumberjack'
pod 'TTTAttributedLabel'
pod 'FLEX'
pod 'GVUserDefaults'
pod 'UMengFeedback', '~> 2.3.4'
pod 'TYAttributedLabel', '~> 2.5.6’
pod 'IQKeyboardManager'
pod 'MWPhotoBrowser'

註意基中本工程中有三個target名字，'zxptUser' ,'zxptUser_local', 'zxptUser_AppStore'

3：不同的target引用不同的第三方插件

target :'zxptUser' do
platform :ios  
pod 'Reachability',  '~> 3.0.0'  
pod 'SBJson', '~> 4.0.0'  
  
platform :ios, '7.0'  
pod 'AFNetworking', '~> 2.0'
end

target :'zxptUser_local' do
pod 'OpenUDID', '~> 1.0.0'
end

註意每個都要以end結尾

4：刪除CocoaPods版本，並安裝指定版本

比如我本來安裝完CocoaPods 1.0.0版，但發現它實現跟先前還是差別滿大的，決定降回0.39這個比較穩定版本；就可以用命令先刪除本地的CocoaPods版本，再指定安裝特定版本；

a 卸載 cocoapods(它會提示你要刪除本地哪個版也可以全刪)

sudo gem uninstall cocoapods

b 安裝 0.39版本

sudo gem install -n /usr/local/bin cocoapods -v 0.39

5：更新PODS後，報diff: /../Podfile.lock: No such file or directory 錯誤

diff: /../Podfile.lock: No such file or directory 

diff: /Manifest.lock: No such file or directory 

error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.

如圖

解決辦法：

查看工程中PROJECT中Configurations中相關配置是否正準，有可能某個分枝指到一個不存在的pods導致；

6：當PODS引入第三方後，項目中引用時發現頭文件卻顯示不存在

排查辦法，可以看到相應的targets裡面的Build Phases中的Link Binary WithLibraries裡面是否有把libPods.a庫引入進來

一般出現沒有引入進來可能是podFile指定的相應Targets導致其它的Targets沒有這個庫；

7：友盟最新版SDK調整

a:#import“MobClick.h”引入頭文件由原來，更新為：#import "UMMobClick/MobClick.h"

b:初始化配置文件也進行更改，採用UMConfigInstance全局變數設置：

    UMConfigInstance.appKey=kUMAnalyticsAppKey;
    UMConfigInstance.channelId=@"App Store";
    [MobClick startWithConfigure:UMConfigInstance];

8：關於融雲跟百度地圖支持IPV6

融雲SDK 從2.5.2開始   百度地圖SDK 從3.0.0開始
