ld：找不到带有 pod 的 -lreact-native-fetch-blob 的库？

Question

I just finished working with android and moved on to Xcode and it's been pretty challenging to work with. I am also unfamiliar with pods, but I know that when I installed them I got this from the log:

    Fetching podspec for `RNVectorIcons` from `../node_modules/react-native-vector-icons`
Fetching podspec for `react-native-fetch-blob` from `../node_modules/react-native-fetch-blob`
Downloading dependencies
Installing QBImagePickerController (3.4.0)
Using RNVectorIcons (4.5.0)
Installing RSKImageCropper (2.1.0)
Installing React (0.11.0)
Using react-native-fetch-blob (0.10.6)

I read that since I have pods with fetch-blob I don't need to use .xcodeproj, instead use .xcworkspace. I deleted the .xcodeproj from the side panel and removed the .a from the Link Binary With Libraries. How do I know if I am using .xcworkspace?

Here is the error:

    ld: warning: directory not found for option '-L/Users/laneyw/Desktop/ReactProjects/exampleapp/ios/build/Build/Products/Debug-iphonesimulator/RNVectorIcons'
ld: warning: directory not found for option '-L/Users/laneyw/Desktop/ReactProjects/exampleapp/ios/build/Build/Products/Debug-iphonesimulator/React'
ld: warning: directory not found for option '-L/Users/laneyw/Desktop/ReactProjects/exampleapp/ios/build/Build/Products/Debug-iphonesimulator/react-native-fetch-blob'
ld: library not found for -lreact-native-fetch-blob

Answer 1

right when you open xcode click 'Open another project' and then navigate to your .xcworkspace file in finder

In my case the blue with white 'A' is the xcodeproj and the white with blue 'A' is the .xcworkspace
