My app deals with phone call.So I added coretelephony framework to my project.But when I try to import the framework to my appdelegate,I get the error "No such file directory" Can any one find the solution for that.I use xcode 4.0.1
HI after you add core telephony framework then add
#import <CoreTelephony/CoreTelephonyDefines.h>
to your appDelegate.h file
It will solve your problem.
