Architecture issue in iOS - ios

I'm using Reachability on my project to get the type of connection used, but an error has ocurred.
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_Reachability", referenced from:
objc-class-ref in ContributionViewController.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I don't know what to do... my project is for iOS 4.3 and I've never had this kind of problem before.
Thx

Did you include the reachability framework in your projects linked libraries ? You can confirm by clicking on your project file on the file list and checking the build phases tab. It should be listed in the linked library section,

ParseFacebookUtil: Apple Mach-O Linker, undefined symbol for architecture x86_64 PFDateFormatter

Error occurs after adding the ParseFacebookUtil
ERROR MESSAGE

FRAMEWORKS
I am using XCode 6.2
Thanks
edit:
I've added the frameworks social, and accounts. Same error still occurs.
I ended up fixing this issue by deleting the Parse and Bolts framework, and re adding it back into the project.
Edit:
The best solution to this issue is by using cocoapods. It handles the dependencies better than manually dragging in the framework files.

Undefined symbols for architecture armv7:

objc-class-ref in addProductViewController.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The addProductViewController object is not found and it was referenced within AppDelegate. You do not link addProductViewController into your app. Check if your Compile Sources section within the Build Phases of your project shows addProductViewController.m
than˚s every body for your help

Crash when using lib file in proj

I have followed this tutorial LINK
but i get a linker error when i added the lib and its .h to the project.
i searched google and i found that -ObjC and -all_load should be addd in setting i did it but the error couldn't be solved.The error is as follows:
ld: warning: ignoring file /Users/techvedika/Desktop/RND/MathTest/MathTest/iCodeBlogsMathLibrary/libICodeMathUtils.a, missing required architecture i386 in file /Users/techvedika/Desktop/RND/MathTest/MathTest/iCodeBlogsMathLibrary/libICodeMathUtils.a (3 slices)
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_MathFunctions", referenced from:
objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
how do i solve this?
Can you please check lipo -info libICodeMathUtils.a on terminal. If it is not listing architecture i386 that means your library is not build for simulator. And it will not work on simulator
obviously, this is not a crash , it's just a link error, your project lack of i386 version libICodeMathUtils.a, so you should first add libICodeMathUtils.a to your project.
The MathFunctions class is missing. Either from your application project or from the SimpleLibrary.a that you use. Make sure it is part of the compilation and linking steps of your build.

Undefined symbols for architecture i386:"_OBJC_CLASS_$_SBJsonParser"

I'm creating a iphone app and its contain SBJson_3.1.1 for login purpose [I'm using webservice for login data] but when I run the project it shows the following error and I cant find what its reason I'm quite new to ios development so please guide me.
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_SBJsonParser", referenced from:
objc-class-ref in ViewController.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1
(use -v to see invocation)
If you are building the SBJson library and have linked your app to that, you will need add the -ObjC and -all_load flags to your linker options.

Issue when implementing iRate

When adding iRate to my app I get this error:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_iRate", referenced from:
objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Sounds like when you added the .m file to your project, it wasn't assigned to your target. Select iRate.m in the project navigator. Then bring up the utilities view on the right side of Xcode. Under Target Membership, make sure your app's target is checked. Try the build again.
