Question

我正在尝试将本机iOS Twitter帐户实现统一。我找到了一个通过Xcode使用原生社交帐户的代码，所以我试图让它与团结沟通，但我得到了这个错误：“使用未声明的标识符'self'”

这是我的代码：

extern "C"
{
    void _PushTwitter(const char * messageTweet)
    {
        //Check Twitter accessibility and at least one account is setup.
        if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {

            SLComposeViewController *tweetSheet =[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];

            //This is setting the initial text for our share card.
            [tweetSheet setInitialText:[NSString stringWithUTF8String:messageTweet]];

            //Brings up the little share card with the test we have pre defind. 
            [self presentViewController:tweetSheet animated:YES completion:nil];

        } else {
            //This alreat tells the user that they can't use built in socal interegration and why they can't.
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Sorry" message:@"You can't send a tweet right now, make sure you have at least one Twitter account setup and your device is running the latest iOS version" delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil];
            [alertView show];
        }

    }
}

我在[self presentViewController ...]部分得到错误。

这是原始代码：

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

    //Each button title we gave to our action sheet is given a tag starting with 0.
    if (buttonIndex == 0) {

        //Check Twitter accessibility and at least one account is setup.
        if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {

            SLComposeViewController *tweetSheet =[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];

            //This is setting the initial text for our share card.
            [tweetSheet setInitialText:@"veasoftware.com made it easy to intergate Twitter with iOS 6! :D "];

            //Brings up the little share card with the test we have pre defind. 
            [self presentViewController:tweetSheet animated:YES completion:nil];

        } else {
            //This alreat tells the user that they can't use built in socal interegration and why they can't.
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Sorry" message:@"You can't send a tweet right now, make sure you have at least one Twitter account setup and your device is using iOS6." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
            [alertView show];
        }
}
}

非常感谢任何帮助。

编辑/解决方案：对于任何感兴趣的人，我发现这篇文章更容易整合（可能是唯一一个）：http://www.theappguruz.com/unity/share-image-and-text-on-twitter-in-ios-using-native-code/就像一个魅力。我正在运行iOS 8，Unity 5和最新版本的Xcode。

您找到的代码可能是objective-c类的一部分，其中定义了 self ，它指向当前对象。

您编写的代码似乎不是类的方法，而是全局函数，这意味着它没有附加对象。

你应该将你找到的代码添加到Unity为你定义的类之一，也许是在UnityAppController.mm中
