在項目中有時候會遇到Library not found for -lPods(這里的IPods指的是你具體的第三方庫)的問題
出現(xiàn)這個錯誤的原因是:xcode在編譯的時候找不到這個庫，從而導(dǎo)致項目無法編譯！
這里給出幾種解決辦法：
第一種：
Search from 'Library' from the Target Settings view and double-click to inspect the value of Library Search Paths
There are two values listed $(inherited) and $(PROJECT_DIR)/Pods/build/Debug-iphoneos. Delete the latter.
Do a full clean, build & run
Run pod install again. Notice that the entry is not restored.
第二種：
Go to Product > Edit Scheme
Click on Build
Add the Pods static library, and make sure it's at the top of the list
Clean and build again
第三種：
If that doesn't work, verify that the source for the spec you are trying to include has been pulled from github. Do this by looking in /Pods/. If it is empty (it should not be), verify that the ~/.cocoapods/master//.podspec has the correct git hub url in it.
第四種：
If still doesn't work, check your XCode build locations settings. Go to Preferences -> Locations -> Derived Data -> Advanced and set build location to "Relative to Workspace".
第五種：（網(wǎng)上較為常用的解決辦法）
獲取 庫文件所在的那個文件夾 路徑，添加到 Target的Build Settings界面
找到library search paths，然后進行添加！
第六種：（感覺較為無奈的辦法）
重新使用pod update 方法更新所有的第三方(反正我沒成功，不過網(wǎng)上有人成功過)
第七種：
I've found that $(inherited) was missing from my Other Linker Flags build setting.
Applying this option fixed a missing library issue I was seeing.
