to log in my user.
However, I received this error:
Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘+[FBSDKInternalUtility validateURLSchemes]: unrecognized selector sent to class 0x10b695e40’
I have looked through all the header files; but I just cannot find a class named as FBSDKInternalUtility. Before the upgrade of Parse 1.7.2 and Facebook SDK v4, my log in system works perfectly.
