I am integarting canvaspop in my application.When I am integrating it in sample application it is working fine.But when I am using it in my app with other 3rd pary framework like GPUimage,IKImagePicker,xpload and other more.I am getting these errors while linking framework to my app.

I think there are some setting in the build setting which have to change to successfully link this framework to app.
Thanks
Try having a look at this question and solution:
Conflict between class and static library
It explains how the .m files are possibly conflicting with each other.
Try out this solution and comment on the outcome.

I've been struggling to get VLC working in my iOS app for a while now. Using Cocoapods, the MobileVLCKit is imported into my project. When I run the app now, it compiles with no problem. However, when I include anything from the MobileVLCKit (MobileVLCKit.h, VLCMediaPlayer.h), the app crashes, telling me that symbols aren't found.
This is the crash:

When I installed VLC through cocoa pods, I got this warning:
The `iOSCamApp [Release]` target overrides the `OTHER_LDFLAGS` build setting defined in `../Pods/Target Support Files/Pods-iOSCamApp/Pods-iOSCamApp.release.xcconfig'. This can lead to problems with the CocoaPods installation
- Use the `$(inherited)` flag, or
- Remove the build settings from the target.
When I add the $(inherited) flag and try to build, I get the following crash:

ld: framework not found MobileVLCKit
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Does anyone know what to do? I've tried so many things and nothing seems to help. Autocomplete is able to read the VLC stuff and autocompletes it for me in Xcode, so the framework should be fine.
Undefined symbols for architecture arm64:
That seems to be the problem. You're compiling for the simulator and apparently MobileVLCKit isn't compiled for it. ld is the linker that complains about this. Have you tried running it on the device?
Check what architectures your project and MobileVLCKit are active on.

I cannot find liphone-lib anywhere in the project. I have been able to build this project effortlessly before. I am using unity 4.5.5 and Xcode 6.1
Please help
Ok I managed to fix it. I had updated to unity 4.5 so it broke my project. I deleted everything and rebuilt again by overwriting old files. That fixed the error.
I am facing this warning in Xcode 5.1.
How to fix this error

when I remove the reference project B, and build the project B single. Then add the yodo1SDK_SNS-AD-ALS-GMG.a to project SampleAppRef, it works well!
When I remove the duplicate file AdViewAdapterDoMob.h and AdViewAdapterDoMob.m from project project B, It works well too! and I can runs and call the code of AdViewAdapterDoMob.m .
project SampleAppRef self doesn't has any code of "AdViewAdapterDomobImpl". So why it has dumplcate symbol?
Can anybody give me some hints?
Try to clear log then press stop. after that clear the log again and quit xcode. restart mac and try again. See if that works.
