You can have an if or case statement where you have a breakpoint set for where
the condition changes.
I used to make a method a long time ago called, get this, -(void)breakpoint,
and have a BP on it, but that's a little overkill.
switch (myVar) {
case (AllIsWell):
break;
case (AllIsNotWell):
NSLog(@"Breakpoint: check your var");
NSLog(@"MyVarValue: ,%@", thatVarIWantToSee);
// put a BP below
break;
}
In the cases, set up the condition you are looking for that will catch the
condition you are looking for. I'm sure you'll need to modify that little
block a bit, but it should spit out the value of your var after the condition
is triggered.
Hope this helps.
