I want to know how i can trace program execution using xcode I want to know which method being called right now as when you add break point in method
Is there any way to do such alike thing without adding breakpoints??

There are a couple of Debugger-related WWDC 2012 videos, one of which shows you how to add a breakpoint that continues automatically after running a debugger command. This is preferred to adding logging as there is no need to keep doing the write-compile-debug loop.
You can add an action to the breakpoint that calls:
expr (void)NSLog(@"self=%p Method1", self);
Having said that I still use log calls, but I use my own logging framework which prints the name of the class and method automatically (using __FUNCTION__ string generated by the compiler).

after search i found that the easiest solution is to put the following code in your methods:
NSLog(@"<%@:%@:%d>", NSStringFromClass([self class]), NSStringFromSelector(_cmd), __LINE__);
Comments
NSLog(@"Check 1 - 2 !");
will show you a log trace ;-)

To add to that partial answer. Adding NSLog's within your code will help you to know where your program is at any given point. By putting
NSLog(@"<method> fired"); or something similar inside of your methods you will be able to look at your console and see what is happening and when, without requiring you to use breakpoints.
