  ld: symbol(s) not found for architecture i386
  clang: error: linker command failed with exit code 1 (use -v to see invocation)

these are the frameworks which i've added in my project:

CoreText.framework
OpenGLES.framework
Security.framework
MobileCoreServices.framework
StoreKit.framework
SystemConfiguration.framework
CFNetwork.framework
MessageUI.framework
AdSupport.framework - (**) Optional
QuartzCore.framework
UIKit.framework
CoreGraphics.framework
Foundation.framework
libz.dylib
libsqlite3.dylib

and this is the linker flag which i have added

-ObjC

How Do i Fix this? please help.

Answer 1

You need to link the CoreText framework into your app.
