更新CocoaPods碰到的问题及知识点

1：解决CocoaPods安装时报的问题，http://ruby.taobao.org/latest_specs.4.8.gz 报404

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

原因：淘宝的那个镜像(https://ruby.taobao.org/ )已经不可用了。所以我们现在用最新支持的ruby镜像(https://gems.ruby-china.org/)

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

gem sources -a https://gems.ruby-china.org/

gem sources -l

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

当然如果你是第一次安装时（目前网上有些安装资料可能还指向淘宝的http）：

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

1.1

$ gem sources -l  （用来检查使用替换镜像位置成功）

1.2 报证书错误

$ gem sources -a https://gems.ruby-china.org/

ERROR:  SSL verification error at depth 1: unable to get local issuer certificate (20)

ERROR:  You must add /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority to your local trusted store

ERROR:  SSL verification error at depth 2: self signed certificate in certificate chain (19)

ERROR:  Root certificate is not trusted (/C=US/O=GeoTrust Inc./CN=GeoTrust Global CA)

https://gems.ruby-china.org/ added to sources

解决方式：

$ sudo curl -O http://curl.haxx.se/ca/cacert.pem

$ sudo mv cacert.pem cert.pem

1.3：当pod update时卡在Setting up CocoaPods master repo 就更新一下ruby

淘宝的那个镜像(https://ruby.taobao.org/ )已经不可用了。所以我们现在用最新支持的ruby镜像(https://gems.ruby-china.org/)
  需要的命令行：
$ gem sources -r https://rubygems.org/ （移除旧版本的镜像，如果你不知道你电脑上目前用的是什么镜像，可用  $ gem sources -l  来查看）
 
$ gem sources -a https://gems.ruby-china.org/ （增加可用的镜像）
  
$ gem sources -l  （用来检查使用替换镜像位置成功）

2:CocoaPods更新版本后，安装跟更新第三方报错

可以通过 $ pod --version 查看版本号；

原因是podfile升级到最新版本，pod里的内容必须明确指出所用第三方库的target；可以修改Podfile文件的配置文件，让它兼容不指定固定版本；且又不报错；

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' #不要更新此库 源代码已被修改
pod 'SMPageControl', '~> 1.2'
pod 'FMDB'
pod 'GTSDK'
pod 'BaiduMapKit' #百度地图SDK
pod 'UMengAnalytics-NO-IDFA'#友盟统计无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要换成当前target名，最后不要忘记增加一个end结尾,当然如果你的工程是有多个target都要引用；如下：

abstract_target 'defaults' do

platform :ios, '7.0'

pod 'AFNetworking', '~>2.5.0'

pod 'ReactiveCocoa', '~> 2.5'

pod 'JSONModel', '~> 1.0.1'

pod 'Masonry','~>0.6.1'

pod 'FMDB/common' , '~>2.5'

pod 'FMDB/SQLCipher', '~>2.5'

pod 'CocoaLumberjack', '~> 2.0.0-rc'

pod 'SVPullToRefresh', '~> 0.4.1'

pod 'GTSDK','1.4.3'

pod 'RongCloudIMKit', '2.6.7'

pod 'UMengSocialCOM', '5.2.0'

pod 'RealReachability'

target 'Blossom'

end

target 'Blossom_test'

end

target 'Blossom_bls'

end

target 'Blossom_dongguan'

end

target 'Blossom_qijia'

end

target 'Blossom_shanghai'

end

target 'Blossom_zhengzhuang_test'

end

target 'Blossom_bls_test'

end

end

注意基中'defaults'一定不要存在，下面记得写target,可以查看官网的写法：https://guides.cocoapods.org/using/the-podfile.html

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

注意每个都要以end结尾

4：删除CocoaPods版本，并安装指定版本

比如我本来安装完CocoaPods 1.0.0版，但发现它实现跟先前还是差别满大的，决定降回0.39这个比较稳定版本；就可以用命令先删除本地的CocoaPods版本，再指定安装特定版本；

a 卸载 cocoapods(它会提示你要删除本地哪个版也可以全删)

sudo gem uninstall cocoapods

b 安装 0.39版本

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

5：更新PODS后，报diff: /../Podfile.lock: No such file or directory 错误

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.

如图

解决办法：

查看工程中PROJECT中Configurations中相关配置是否正准，有可能某个分枝指到一个不存在的pods导致；

6：当PODS引入第三方后，项目中引用时发现头文件却显示不存在

排查办法，可以看到相应的targets里面的Build Phases中的Link Binary WithLibraries里面是否有把libPods.a库引入进来

一般出现没有引入进来可能是podFile指定的相应Targets导致其它的Targets没有这个库；

7：友盟最新版SDK调整

a:#import“MobClick.h”引入头文件由原来，更新为：#import "UMMobClick/MobClick.h"

b:初始化配置文件也进行更改，采用UMConfigInstance全局变量设置：

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

8：关于融云跟百度地图支持IPV6

融云SDK 从2.5.2开始   百度地图SDK 从3.0.0开始
