Parse integration into Xcode app

Question

Hi guys.
I'm getting 4 errors when i try to integrate parse into my appdeletage.m code. I copied everything correctly from parse SDK and added all of the necessary frameworks. and I'm still getting these 4 errors. Says something about "unidentified symbols"

Answer 1

I'm a bit of  a beginner, but why are you putting all this in the delegate? If you want to use these functions from some library, you should use them in the classes that need them. But it looks like the library they are coming from has not been properly installed or is missing .h files in the compiler/linker path.
