Hi,
I actually write a C++ wrapper class upon CFPreferences. In a value writer method the program crashes when it tries to create a mutable copy from a freshly retrieved dictionary.
The code is:
void Config::WriteInt(char* section, char* key, int value)
{
CFStringRef ksect = MY_CFSTRING(section); //section
CFStringRef kdict = MY_CFSTRING(key); //key in dict
CFNumberRef val = CFNumberCreate(NULL, kCFNumberIntType, &value);
CFDictionaryRef dict0 = CFPreferencesCopyAppValue(ksect, kCFPreferencesCurrentApplication);
CFMutableDictionaryRef dict;
if (dict0) {
CRASH HERE! => dict = CFDictionaryCreateMutableCopy(NULL, 0, dict0);
CFRelease(dict0);
} else {
dict = CFDictionaryCreateMutable(NULL, 1, NULL, NULL);
}
...
and the crash log:
Exception: EXC_BAD_ACCESS (0x0001)
