我有这个方法崩溃[NSKeyedArchiver archivedDataWithRootObject:self.data]:

- (void) synchronize
{
    @synchronized (self.data)
    {
        NSData *encryptedData = [[NSKeyedArchiver archivedDataWithRootObject:self.data] NL_AES256EncryptWithKey:userKey]; //La ça crash
        BOOL success = [NSKeyedArchiver archiveRootObject:encryptedData toFile:[self filename]];

        if (!success)
        {
            // we lost some data :(
            NSLog(@"Failed to synchronize to file %@", [self filename]);
        }
    }
}

问题是对对象方法(getter/setter)的所有访问都受到保护,@synchronized(self.data)并且此属性是私有的.

任何的想法？

编辑:崩溃日志是明确的:

我目前正在研究由8制作的交互式iOS通知,老实说,我真的很难看到我的按钮.使用下面的代码,我看不到我的按钮:

// INTERACIVE

UIMutableUserNotificationAction *acceptAction =
[[UIMutableUserNotificationAction alloc] init];

acceptAction.identifier = @"ACCEPT_IDENTIFIER";
acceptAction.title = @"Accept";
acceptAction.activationMode = UIUserNotificationActivationModeBackground;
acceptAction.destructive = NO;
acceptAction.authenticationRequired = NO;

UIMutableUserNotificationAction *maybeAction =
[[UIMutableUserNotificationAction alloc] init];

maybeAction.identifier = @"MAYBE_IDENTIFIER";
maybeAction.title = @"Maybe";
maybeAction.activationMode = UIUserNotificationActivationModeBackground;
maybeAction.destructive = NO;
maybeAction.authenticationRequired = YES;


UIMutableUserNotificationAction *declineAction =
[[UIMutableUserNotificationAction alloc] init];

declineAction.identifier = @"DECLINE_IDENTIFIER";
declineAction.title = @"Decline";
declineAction.activationMode = UIUserNotificationActivationModeBackground;
declineAction.destructive = YES;
declineAction.authenticationRequired = NO;


UIMutableUserNotificationCategory *inviteCategory =
[[UIMutableUserNotificationCategory alloc] init];

inviteCategory.identifier = @"INVITE_CATEGORY";

[inviteCategory setActions:@[acceptAction, maybeAction, declineAction]
                forContext:UIUserNotificationActionContextDefault]; …
