Question

I am trying to implement InAppSettingKit and getting this error:

  Undefined symbols for architecture i386:
"_OBJC_CLASS_$_MFMailComposeViewController", referenced from:
  objc-class-ref in IASKAppSettingsWebViewController.o
  objc-class-ref in IASKAppSettingsViewController.o
 ld: symbol(s) not found for architecture i386
 clang: error: linker command failed with exit code 1 (use -v to see invocation)

InAppSettingKit is used for integrating settings inside the app.

The code I have imported had some ARC issues so I just disabled ARC for every file I had imported.But now I get this error.

I don’t have any file named MFMailComposeViewController so how can I include it in Compile Sources?

I am new to iOS, so it would be appreciated if anyone can explain the steps to integrate setting inside the App.

Since you are new, you may not be familiar with how to add frameworks. Select the project in the project explorer, then select a target and then Build Phases. In Build phases, there is a section for “Link Binary with libraries”. Select that option and click on + sign. It will show you a list of frameworks and you have to select and include “MessageUI.framework” from there.
