Viewing NSData contents in Xcode

Question

I am running Xcode and I would like to dump out a NSData*. The variable in question is buffer. Is there a way to do this through the UI or the GDB debugger?

Answer 1

In lldb, the following works to let you examine the contents of NSData objects:

You can get the address of the bytes for use with various debugger commands like this:

p (void *)[buffer bytes]

You see something like this:

(void *) $32 = 0x0b5e11f0

If you know the underlying data is a string, you can do this:

p (char *)[buffer bytes]

and the debugger will output:

(char *) $33 = 0x0b5e11f0 "This is the string in your NSData, for example."
