Hi,
I'm finding with Debugging and Xcode is really hard looking a
certain
variable types can you
1) Actually look at CF and NS objects when within the console say
via a
print command ???.
Not sure what you mean here. the print command in the console will
show you the contents of the CF & NS types, but most often these are
either opaque types - i.e. the debugger doesn't know what the
structure fields are, or the fields are not very helpful because
getting from them to the actual contents of the object is not trivial.
You can use the "print-object" command ("po" for short) to run the
"description" method for the object. For CF objects, the command
CFShow fulfills the same purpose.
2) Looking at char* and strings, by default the debugger always
crops the
text but I want to look at the whole thing, this is also true if
you do it
in the console as well. Can you can the print statement to show the
whole
thing ???.
In the console type:
(gdb) set print elements 0
and it will print the entire contents of strings.
3) Is there anyway to just look at memory and then also any size.
In Xcode 1.5 and above there is a memory browser under Debug->Tools-
>Memory Browser.
In the gdb console, do:
(gdb) help x
to get info about the "examine" command, which is what you want here.

Thanks in advance,
