Question

How can I trace the method calls and their sequence while a iPhone app is running? Which Instrument I should use?

Answer 1

No Instrument does this directly. A couple of options to get this kind of information:

1) Set a breakpoint in the debugger. You can then trace the execution with the “step over” “step into” and “step out” buttons.

2) Put NSLogs at the places in your code that interest you:

-(void) someMethod {
  NSLog (@"Starting someMethod");
  // rest of the method is here
}

You can then read the NSLogs in the console.
