Hi,

I have an mystique behavior  in the NSMutableDictionary

one cannot while one contains a nil for key and value so when print in
nslog

*{ *

**

*"key" = "value";  *

**

*(null) = (null); *

*} *

one is not an NSNull


then

NSArray *keys = [_f allKeys];

 throwing an exception

*Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '*** -[NSArray initWithObjects:count:]: attempt to insert nil
object at objects[31]' *

--
best regards
Ariel
