facebook - 呈现社交 View Controller Cocos2d

Question

我正在尝试使用社交框架从 Cocos2d 中呈现“发布到 Facebook” View Controller 。这是我通常在 Storyboard 应用程序中使用的代码

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
    SLComposeViewController *facebook = [[SLComposeViewController alloc] init];
    facebook = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
    [facebook setInitialText:[NSString stringWithFormat:@"text"]];
    [self presentViewController:facebook animated:YES completion:nil];
    [facebook setCompletionHandler:^(SLComposeViewControllerResult result) {
        NSString *output;
        switch (result) {
            case SLComposeViewControllerResultCancelled:
                output = @"Action Cancelled";
                break;
            case SLComposeViewControllerResultDone:
                output = @"Posted";
                NSUserDefaults *ud = [NSUserDefaults standardUserDefaults];
                [ud setInteger:1 forKey:@"Shared"];
                [ud synchronize];
            default:
                break;
        }
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Facebook" message:output delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil];
        [alert show];
    }];
}

我如何在 Cocos2d 中启动并运行它？目前它会对该行发出警告

[self presentViewController:facebook animated:YES completion:nil];

提前致谢

Answer 1

在 cocos2d 2.0 中你可以使用 [CCDirector sharedDirector] 而不是 self。

[[CCDirector sharedDirector] presentViewController:facebook animated:YES completion:nil];

之所以可行，是因为 CCDirector 继承自 UIViewController。
