Hello,
I seem to be having an acute case of brain blockage, I can't figure
out what I'm doing wrong with a simple thing I've done a thousand times.
I have an NSDictionary that contains, well, objects. When I call
-objectForKey: I get nil for keys that are definitely in there.
The dictionary gets constructed like this:
[NSDictionary dictionaryWithObjectsAndKeys:
kUnitsKey, [NSNumber numberWithDouble:units],
kValueKey, [NSNumber numberWithDouble:value],
kIsMetricKey, [NSNumber numberWithBool:isMetric],
nil];
This is later used elsewhere, where it seems to arrive intact.
po dict
outputs this:
------ Debugger output ------
Printing description of dict:
{
1 = kIsMetricKey;
"3.852019958611236" = kValueKey;
200 = kUnitsKey;
}
---- Debugger output end ----
kUnitsKey, kValueKey and kIsMetricKey are declared in a separate header as
extern NSString *kUnitsKey;
extern NSString *kValueKey;
extern NSString *kIsMetricKey;
and defined in a .m as
NSString *kUnitsKey = @"kUnitsKey";
NSString *kValueKey = @"kValueKey";
NSString *kIsMetricKey = @"kIsMetricKey";
po kUnitsKey
yields
(NSString *) $11 = 0x0000000100323f68 kUnitsKey
accordingly for the other keys. Yet
[dict objectForKey:kUnitsKey]
returns nil
po [dict objectForKey:kUnitsKey]
yields
(id) $10 = 0x0000000000000000 <nil>
The keys are unique, there are no duplicates with different values
elsewhere.
I'm using Xcode 4.3.2 on Lion 10.7.3, fully updated, this is a Mac OS X,
project compiled with Apple LLVM 3.1 debugged using LLDB. Even tried
LLVM GCC4.2 and I did a full clean and recompile, same result.
So it's me. What's wrong?
Thanks for any pointers!
Regards
Markus
