How can I replace uniqueIdentifier with CFUUIDCreate?
ios, uniqueidentifier
Solution
iOS < 6.0
// Create universally unique identifier (object)
CFUUIDRef uuidObject = CFUUIDCreate(kCFAllocatorDefault);
// Get the string representation of CFUUID object.
NSString *uuidStr = (__bridge_transfer NSString *)CFUUIDCreateString(kCFAllocatorDefault, uuidObject);
CFRelease(uuidObject);
iOS >= 6.0
NSString* UDID = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
Problem
I am trying to activate APNS. Because `uniqueIdentifier` is deprecated, I'm trying to use `CFUUIDCreate` with the following code: ``` UIDevice *dev = [UIDevice currentDevice]; NSString *deviceUuid; if ([dev respondsToSelector:@selector(uniqueIdentifier)]) deviceUuid = dev.uniqueIdentifier; else { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; id uuid = [defaults objectForKey:@"deviceUuid"]; if (uuid) deviceUuid = (NSString *)uuid; else { CFStringRef cfUuid = CFUUIDCreateString(NULL, CFUUIDCreate(NULL)); deviceUuid = (__bridge NSString *)cfUuid; CFRelease(cfUuid); [defaults setObject:deviceUuid forKey:@"deviceUuid"]; } } ``` How can I replace `uniqueIdentifier` with `CFUUIDCreate`?
