IPhone: How can I use gcov?

I am trying to use gcov on the iPhone Project and following the instructions from Apple described here here , but this will not work.

When I create and set up a project, a .gcda file is created for each object file. But no executed lines are written to .gcda files. (CoverStory shows that all coverage is 0%)

I just added a simple class to the template project as follows.

@interface SomeClass : NSObject
- (void)func1:(BOOL)flag;
@end

@implementation SomeClass
- (void)func1:(BOOL)flag {
  if (flag) {
    NSLog(@"flag is YES");
  }
  else {
    NSLog(@"flag is NO");  
  }
}
@end

I highlighted this class and called func1 in the application: didFinishLaunchingWithOptions, and I expected SomeClass coverage to be shown (50% or so).

I am using OSX 10.6.4, iPhone SDK 4.0 and Xcode 3.2.3. Need a few more configurations? Please guide.
