问题
I am trying to run app on the iphone 6 and I get this error. I get the error after making the facebook login. Normally, it is working successfully on the simulator. I couldn't find why it gives the error.
Error:
*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArray0 objectAtIndex:]: index 0 beyond bounds for empty NSArray'
*** First throw call stack:

libc++abi.dylib: terminating with uncaught exception of type NSException

Since you posted no stack trace, I assume you want to learn how to find bugs like this. First, in Xcode, set a breakpoint on Objective-C exceptions, so you find where exactly the crash happens.
The error says clearly that you are trying to access array [0] for an NSArray that is empty. Once you find the location of the crash that should be easy to find.
