When I try to Time-Profiling Third party app(Example: Facebook) using Instruments, I got this error below, "Permission to debug com.facebook.Facebook was denied. The app must be signed with a development identity (e.g. iOS Developer)." Is there is any workaround to Time-Profile/monitor third party app like facebook using instrument or any other tool? Thanks in advance.

When using Time Profiler for finding the time needed for each method(executed) in iOS App. Some written(not system) method couldn’t appear in Call tree. (Please Note: Some of written methods appeared and some method don't) Anything need to add/do in Instrument or filter for finding those missing methods in call tree. Or is there any criteria for some methods not appearing in the call tree, Specially ViewController life cycle method or if less work done in some method. viewDidLoad() sometimes found and sometimes not. viewWillAppear(), viewDidAppear(), viewWillDisappear(), viewDidDisappear() couldn't find any time. Please clarify the issue. Thanks in advance.
