Question

我是cocoa2d的新手。我正在尝试使用presentViewController进行Facebook分享。

这是代码：

-(void)shareFB:(NSString *)text
{
    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

        SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

        [controller setInitialText:text];

        [[CCDirector sharedDirector]presentViewController:controller animated:YES completion:nil];
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Sorry!" message:@"Please add Facebook account in settings menu" delegate:Nil cancelButtonTitle:@"OK" otherButtonTitles:Nil, nil];
        [alert show];
    }
}

它发出警告：

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

那： CCDirector可能无法响应＆＃39; presentviewcontroller：animated：completion：＆＃39;

Answer 1

好的，我得到了解决方案。

我的 CCDirector 是 NSObject 类型。我只需将其更改为 UIViewController 即可。感谢@Blisskarthik的帮助。

您好我已经编辑了您的代码，几乎没有更正并粘贴在下面。它工作正常

SLComposeViewController *faceBookPost = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

[faceBookPost setInitialText:@"I am playing game"];
[faceBookPost addURL:[NSURL URLWithString:@"http://www.yourlink.com"]];
[[CCDirector sharedDirector]presentViewController:faceBookPost animated:YES completion:nil];
            faceBookPost.completionHandler = ^(SLComposeViewControllerResult result)
            {
                [[CCDirector sharedDirector] resume];
                [[CCDirector sharedDirector] startAnimation];
                [[CCDirector sharedDirector]dismissViewControllerAnimated:YES completion:nil];
            };

其他请按照此步骤进行操作

使用像这样的uinavigationcontroller在AppController中创建一个接口

@interface MyNavigationController : UINavigationController <CCDirectorDelegate>
@end 

@interface AppController : NSObject <UIApplicationDelegate>
{
UIWindow *window_;
MyNavigationController *navController_;
CCDirectorIOS   *director_;
}

在app controller的didFinishLaunchingWithOptions中设置导航控制器

navController_ = [[MyNavigationController alloc] initWithRootViewController:director_];
navController_.navigationBarHidden = YES;
[director_ setDelegate:navController_];
// set the Navigation Controller as the root view controller
[window_ setRootViewController:navController_];

然后在你调用SLComposeViewController的类中出现像这样的视图

 AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
 [[app navController] presentViewController:faceBookPost animated:YES completion:nil];

两种类型都运行良好

CCDirector可能无法响应presentviewcontroller：动画
