UUID 쉽게 사용하기 ㅋㅋ


KeychainItemWrapper.h/m 파일은 업로드된 것을 사용해도 되고 아래 URL에 있는 내용을 사용해도 됨.

(어차피 업로드 된 것도 저거 다운 받아서 업로드 한거니.. ㅋㅋ)


# KeychainItemWrapper.h 파일

https://developer.apple.com/library/ios/samplecode/GenericKeychain/Listings/Classes_KeychainItemWrapper_h.html


# KeychainItemWrapper.m 파일

https://developer.apple.com/library/ios/samplecode/GenericKeychain/Listings/Classes_KeychainItemWrapper_m.html


#import "KeychainItemWrapper.h"

- (NSString *)getDeviceUUID {
    KeychainItemWrapper *keychainItemWrapper =
    [[KeychainItemWrapper alloc] initWithIdentifier:@"UUID-Identifier" accessGroup:nil];
    NSString *uuidString = [keychainItemWrapper objectForKey:(__bridge id)(kSecAttrAccount)];
    
    if (uuidString == nil || [uuidString length] == 0) {
        // if there is not UUID in keychain, make UUID and save it.
        CFUUIDRef uuidRef = CFUUIDCreate(NULL);
        CFStringRef uuidStringRef = CFUUIDCreateString(NULL, uuidRef);
        CFRelease(uuidRef);
        uuidString = [NSString stringWithString:(__bridge NSString *)uuidStringRef];
        CFRelease(uuidStringRef);
        
        // save UUID in keychain
        [keychainItemWrapper setObject:uuidString forKey:(__bridge id)(kSecAttrAccount)];
    }
    
    return uuidString;
}
