iOS6 UUID

最近剛好碰到推播註冊
卻讓我自己混入了一團迷思裡面
因為我一直把推播註冊的token跟UUID搞混了
真是個笨蛋ㄚ

參考link

[UIDevice currentDevice].identifierForVendor.UUIDString;
or
NSString *uuid_str = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; uuid_str = [uuid_str stringByReplacingOccurrencesOfString:@"-" withString:@""];
