Casting a CFDictionaryRef to NSDictionary?

Question

I have the code (stripped down):

CFDictionaryRef *currentListingRef;
//declare currentListingRef here
NSDictionary *currentListing;
currentListing = (NSDicti         


        

Answer 1

In ARC, this should be done this way:

CFDictionaryRef currentListingRef = ...;
NSDictionary *currentListing = CFBridgingRelease(currentListingRef);

This releases the CF object and transfers ownership of the object to ARC otherwise you should release CF object manually.

Answer 2

Try this code,

NSDictionary *ssidList = (__bridge NSDictionary*)myDict;
NSString *SSID = [ssidList valueForKey:@"SSID"];

Answer 3

ARC changed the way bridging works.

NSDictionary *original = [NSDictionary dictionaryWithObject:@"World" forKey:@"Hello"];
CFDictionaryRef dict = (__bridge CFDictionaryRef)original;
NSDictionary *andBack = (__bridge NSDictionary*)dict;
NSLog(@"%@", andBack);
