更新CocoaPods碰到的问题及知识点 转载

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：淘宝停止基于 HTTP 协议的镜像服务 需要改用https的协议

复制代码
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
复制代码
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://ruby.taobao.org/
gem sources -l
sudo gem install -n /usr/local/bin cocoapods

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；

复制代码
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
复制代码
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；则要使用link_with（这个一定要放在文件第一行）如下：

复制代码
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’
复制代码
注意基中本工程中有三个target名字，’zxptUser’ ,’zxptUser_local’, ‘zxptUser_AppStore’

3：不同的target引用不同的第三方插件

复制代码
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
复制代码
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
