Question

Is there a way to view the key/value pairs of a NSDictionary variable through the Xcode debugger? Here’s the extent of information when it is fully expanded in the variable window:

Variable  Value      Summary jsonDict  0x45c540   4 key/value pairs  NSObject {...}   isa     0xa06e0720 

I was expecting it to show me each element of the dictionary (similar to an array variable).

In the gdb window you can use po to inspect the object.

given:

NSMutableDictionary* dict = [[NSMutableDictionary alloc] init]; [dict setObject:@'foo' forKey:@'bar']; [dict setObject:@'fiz' forKey:@'buz']; 

setting a breakpoint after the objects are added you can inspect what is in the dictionary

(gdb) po dict {   bar = foo;   buz = fiz; } 

Of course these are NSString objects that print nicely. YMMV with other complex objects.
