I search a lot but in every post its sid to add Storkit.. but i have already added it but still getting error. even i have cleaned the project a lot of time.
Just ensure that you have added the following libraries,
1.AudioToolbox
2.MessageUI
3.SystemConfiguration
4.CoreGraphics
Also the frameworks,
1.MessageUI.framework
2.StoreKit.framework
3.SystemConfiguration.framework
According to your error message there is a problem with StoreKit.framework...Please verify that...
Refer: build error when add Admob in iOS app
Add AdSupport.framework, also make it as optional
It says that your StoreKit binary is not build for i386. This should not happen with the default one. Did you download if separately from somewhere? You can find the default here:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer‌​/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/StoreKit.framework
Use that.

Upgrade from Facebook iOS SDK 3.2.1 to 3.5 gave me an error with FBCrypto

After installing the new sdk I cleaned the project and build it. It fails with this message:
Undefined symbols for architecture i386:

+[FBCrypto randomBytes:] in FacebookSDK(FBCrypto.o)

Same problem anyone? Solutions?
Well, you need to include the security framework and the libsqlite3.dylib as stated here.
It works now.
edit
Also found this now...
Jumping on this, im running into the same issue, I saw that the FBSDK needs the Security, AdSupport, etc. Here's my linked libraries:
My error is the same:

All the other framework dependencies are good to go as far as I can tell. A Vlean->Build didn't fix it either. Thanks.
Edit: Got it. I needed to re Add Files to Project and check the Add to Target button.. basically XCode automagicka

Ar metio build error

When I'm trying to run the project i receive the following errors
Here is the log.

Does any one knows what the reason might be.
This project has bind with the Metio . AR framework.
Thanks
Click on your Project and go to Build Settings and change the value of Build Active Architecture only to yes.
Let me know if it solves the error:)

I am new to iOS so any help would be greatly appreciated!!
Seems like you are compiling for the simulator (i386) with a library for the Device (ARM). Either compile for the device and run on it or get an i386 version of the library and run with it on the simulator.
For those who need it, the issue was that my XPathQuery.m file was not in the Complied Sources list. It was as simple as that!
Just posting this for future reference! Hope it helps someone!
