Undefined symbols for architecture i386 using libsqlite3.dylib with FMDB Xcode 7 ios9

问题

I am using Xcode 7 and iOS 9 to create a simple app which saves the data and retrieves it using sqllite3. However I am getting the following error message while Building the app using libsqlite3.dylib library and FMDB retrieved from github.

Undefined symbols for architecture i386:

I am driving myself crazy after searching around however could not find any solution. Please suggest. Thanks in advance.

回答1:

Check whether if libsqlite3.dylib is added in the Link Binary with Libraries section in Build Phases

回答2:

It doesn't look like your project is linking against libsqlite3. Double check that it's linking against it, and if it is, maybe add it as a linker flag.
