I'm working with developing an application for iPhone in Objective-C
Can anyone tel me how to solve this error:
".obj_class_name_CUIFramework", referenced from:
collect2:ld returned 1 exit status
literal-pointer#_OBJC#_cls_refs#CUIFramework in MF_CoreAppDelegate.o
symbol(s) not found
I tried to compile my code, i don't have idea for what this error is related to. Please help.what could be the problem?
i've added Foundation framework and UIKit framework
Your code's well-formed, so compiles just fine. When the linker tries to link your application to the frameworks you use, it finds that you reference a framework that's not been imported to your application.
It looks like your code is using a class CUIFramework, but that you haven't added the appropriate framework to your project.

i got some problem when i trying to include framework within framework. i try to make subframework in swift language. when i run in simulator work perfectly but in device i have error “Reason: no suitable image found. Did find:”
the following is an error message:

You are not allowed to submit an app to the App Store with a framework embedded inside another framework. All frameworks must be inside the main app bundle's Frameworks folder. This does not mean you cannot link one framework against another, though. Just specify framework B inside framework A's Link Binary With Libraries build phase, and don't embed it.
I am getting this error any solution please ?
Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_ASIdentifierManager", referenced from:
objc-class-ref in FacebookSDK(FBSettings.o)
You need to link your application with AdSupport.framework. This framework is available in iOS6.0 and later. If your application is targeted to use iOS versions less than 6.0 then you need to link to AdSupport.framework as Optional instead of Required.
The Facebook developers page mentions the steps to upgrade your FB SDK. https://developers.facebook.com/docs/ios/upgrading-from-3.0-to-3.1/. You can find the list of URLs for various SDK versions on this page.
Check it out.
Hope that helps!
I think you didn't add AdSupport.framework. Also remember to remove -all_load linker flag.
The message hints can't find the class ASIdentifierManager, because the corresponding framework not really add it to the object. Just add the framework which includes the class.
I'm trying to simulate touch in iOS. There some pointers in SO suggest that I could try GraphicsServices/GSEvent.h in the private framework. However, when I followed the steps here, I got these errors:
Undefined symbols for architecture armv7:
"_GSCopyPurpleNamedPort", referenced from:
-[TestGraphicsServicesAppDelegate application:didFinishLaunchingWithOptions:] in TestGraphicsServicesAppDelegate.o
"_GSSendEvent", referenced from:
-[TestGraphicsServicesAppDelegate application:didFinishLaunchingWithOptions:] in TestGraphicsServicesAppDelegate.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Any suggestion? Thanks
edit:
the code I used is from Using GraphicsServices.h/GSEvent as well as compiling CLI iPhone tools with Xcode.
Looks like the errors are from this line.
mach_port_t thePortOfApp = GSCopyPurpleNamedPort...
GSSendEvent(&record, thePortOfApp);
OK, I think I made some mistakes when I added the framework.
Somehow I got my project working now.
The errors have gone away after I did a couple things.
In Build Setting, I changed Always Search User Paths to Yes.
Added the path to the private header in User Header Search Paths.
Also, in Build Phrases tab, I add the GraphicsServices in the Link Binary with Libraries section.
Now I can do simple stuff like GSEventLockDevice() and simulating pressing home button.
Still have no clue about touch.
When i use the following code i am getting the error message that says
""_CGAffineTransformMakeRotation", referenced from:"
companyNameLbl.transform=CGAffineTransformMakeRotation(30);
Can anyone please tell me what will be the reason for this error.
If I remember correctly, those transformations require that you link against the CoreGraphics Framework.
See How to "add existing frameworks" in Xcode 4? if you have difficulties adding new frameworks in XCode.
I just wanna create a MS plugin to hook SpringBoard. I'm following "gojohnnyboi" tutorial from here "http://www.ipodtouchfans.com/forums/showthread.php?t=103558".
To create a dylib on XCode, I'm following "SkylarEC" tutorial. I mix these two great tutorials and finally got succeed by getting a dylib. But when I placed the dylib in the /Library/MobileSubstrate/DynamicLibraries/ nothing is happened (no alert was shown).
By evaluating, I found that, this dylib doesn't have any starting point when it was loaded into the memory. So I mentioned a starting point by declaring a constructor in the .mm file like,
__ attribute__((constructor)) static void init()
{
Class _$SBAppIcon = objc_getClass("SBApplicationIcon");
MSHookMessage(_$SBAppIcon, #selector(launch), (IMP) &__$ExampleHook_AppIcon_Launch, "__OriginalMethodPrefix_");
}
But when I'm trying to compile this, I'm getting an error like,
**Undefined symbols:
"_MSHookMessage", referenced from:
init() in ExampleHook.o
ld: symbol(s) not found
collect2: ld returned 1 exit status.**
Does anyone has idea how to solve this? It would be great and more helpful if anyone share the detailed tutorial/instructions to create a dylib on XCode.
P.S I placed all the libsubstrate.dylib and substrate.h files in the corresponding location. And the locations are,
libsubstrate.dylib : /Developer/Platforms/iPhoneOS.platform/Developer/usr/lib/
substrate.h : /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/include
and my base SDK is 3.0.
You should probably check out iOSOpenDev
(These are very old tutorials. Some modern MS code can be found in http://iphonedevwiki.net/index.php/MobileSubstrate. Eventually someone needs to write an updated tutorial...)
Make sure you have added libsubstrate.dylib in your Xcode project (Add → Existing files...). The compiler will not automatically find which dylib to link unless you tell it so.
Try http://unlimapps.com/?p=15 it will be much easier to compile plugins using the methods in that post
You have to copy CydiaSubstrate.framework to /Library/Frameworks in your mac and link to CydiaSubstrate
#include <CydiaSubstrate/CydiaSubstrate.h>
