Moving from GCC 4 to 3.3 is a much larger step for me than moving
from CW to Xcode. I encountered several small issues with code that
used to work but suddenly stopped. Most where easy to get around by
rearranging the code.
Now I'm totally stuck on a problem. I have code that used to work
fine but stopped to work either when I moved from GCC 4 to 3.3 or I
changed some settings in Xcode. Have I been getting away with
something illegal before or is there a problem/setting I missed?
This does not work (key is not found in dictionary):
-------------
#define kMyKey CFSTR("myKey")
CFMutableDictionaryRef dictRef = ::CFDictionaryCreateMutable(nil,
0,nil,nil);
CFDictionarySetValue(dictRef,kMyKey,CFSTR("myValue"));
CFStringRef returnedValue = CFDictionaryGetValue(dictRef,kMyKey);
CFShow(returnedValue); // null
This works:
-------------
#define kMyKey CFSTR("myKey")
CFStringRef key = kMyKey;
CFMutableDictionaryRef dictRef = ::CFDictionaryCreateMutable(nil,
0,nil,nil);
CFDictionarySetValue(dictRef,key,CFSTR("myValue"));
CFStringRef returnedValue = CFDictionaryGetValue(dictRef,key);
CFShow(returnedValue); // "myKey"
Grateful for any hints!
Rune
