xcode - 如何在 iOS 6 中使用 ACAccountStore 类在 Objective-C 中发布到 Facebook

Question

我想知道如何使用 Xcode 4.5 上的新框架在 iOS 6 上向 Facebook 发布状态消息。谢谢! :)

发布消息非常简单。这几乎就像 Twitter 框架一样。

首先你必须导入框架:社交和账户

#import <Social/Social.h>
#import <Accounts/Accounts.h>

在你的 .h 文件中:

SLComposeViewController *mySLComposerSheet;

此代码必须包含在您的 .m 文件中的操作中:

    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) //check if Facebook Account is linked
    {
      mySLComposerSheet = [[SLComposeViewController alloc] init]; //initiate the Social Controller
        mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; //Tell him with what social platform to use it, e.g. facebook or twitter
                [mySLComposerSheet setInitialText:[NSString stringWithFormat:@"Test",mySLComposerSheet.serviceType]]; //the message you want to post
       [mySLComposerSheet addImage:yourimage]; //an image you could post
        //for more instance methods, go here: https://developer.apple.com/documentation/social/slcomposeviewcontroller#//apple_ref/doc/uid/TP40012205
        [self presentViewController:mySLComposerSheet animated:YES completion:nil];
    }
    [mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
        NSString *output;
        switch (result) {
            case SLComposeViewControllerResultCancelled:
                output = @"Action Cancelled";
                break;
            case SLComposeViewControllerResultDone:
                output = @"Post Successful";
                break;
            default:
                break;
        } //check if everything worked properly. Give out a message on the state.
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Facebook" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
        [alert show];
    }];
