Unable to add the Objective-C client library to project

[Haoyan Geng]

Hello,

I was trying to use the Objective-C client library to let my iOS app interact with Google Cloud Storage.  I followed the instruction on https://code.google.com/p/google-api-objectivec-client/wiki/BuildingTheLibrary to link the iOS static library to my project, but the project failed to build with error messages saying that there are undefined symbols for architecture i386.  I'm under the impression that since I'm building an iOS app, the i386 architecture should not be relevant here?  My project is an iOS app created using Xcode 5.1.1, and the static library (libGTLTouchStaticLib.a) was built for iOS device using the same Xcode environment.  Could anyone give me some hint on what's going on?

Below is the build output:
