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）

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
最近有个妹子弄的一个关于扩大眼界跟内含的订阅号，每天都会更新一些深度内容，在这里如果你感兴趣也可以关注一下(嘿对美女跟知识感兴趣)，当然可以关注后输入：github 会有我的微信号，如果有问题你也可以在那找到我；当然不感兴趣无视此信息；
