How can I import the Google API Objective-C Client Library in to my iOS project without getting errors?

Question

Ok. I've followed all the steps on Google's API page. I am trying to interact with Blogger's api and I'm getting exactly 9 Apple Mach-O Linker errors. How can I import the library and get everything set up and NOT get those errors? Thanks!

Here's the error:

Most likely when you added the files to your project you did not set the target membership for the associated .m files. Select the `GTLService.m` and other GTL .m files and make sure their target membership is set properly. — rmaddy, Jun 20 '13 at 03:21
I just checked and their targets are all set to my app target. — mattwyskiel, Jun 20 '13 at 03:27
Make sure that you have the armv7 architecture included in your build settings under "Architectures" — borrrden, Jun 20 '13 at 03:45
I am getting the same errors, what you do to fix these, thanks — Iqbal Khan, Aug 29 '13 at 12:46
I've checked all the above and I still have the same problem. I'm using the Google Drive SDK with Xcode 6.1 and iOS 8.1 — Salman Hasrat Khan, Nov 03 '14 at 05:10
A year later and I'm having the same problem. What was the solution? — PWiggin, Dec 13 '15 at 23:49

I'll just quote what @borrrden already wrote. This worked for me.

Make sure that you have the armv7 architecture included in your build settings under "Architectures"

I've done that, but it still gives me the same linker error. I am using the Google Drive SDK and Xcode 6.1 with iOS 8.1 – Salman Hasrat Khan Nov 03 '14 at 05:09

I have the same problem just like you. I solve by check all the steps again . I found the problem.HAHA!

Build phases --> Link Binary With Libraries

at there all the framework disappeared after running the code! So what you have to do is add the framework again.

Please add the framework as follows: libGTLTouchStaticLib.a + Security.framework + SystemConfiguration.framework + MobileCoreServices.framework

How can I import the Google API Objective-C Client Library in to my iOS project without getting errors?
