如何使用ios 6.0中的社交框架从iphone应用程序在Facebook上分享图像？

Question

我使用下面给出的代码。 但它只发布图像到Facebook。

UIImage *image = [UIImage imageNamed:@"testimage.png"];
    NSString *caption = @"Gud Mng";
    NSArray *activityItems = @[image, caption];
    // Initialize Activity View Controller
    UIActivityViewController *vc = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
    // Present Activity View Controller
    [self presentViewController:vc animated:YES completion:nil];

Answer 1

添加社交框架。 在视图控制器中导入。

SLComposeViewController *socialVc=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
NSData *data = UIImageJPEGRepresentation(self.defaultImageView.image, 1.0);
[socialVc addImage:[UIImage imageWithData:data]];


[socialVc setInitialText:[NSString    stringWithFormat:@"%@",self.captionTextFeild.text]];
[socialVc addURL:[NSURL URLWithString:@"via www.coderit.com"]];
[self.navigationController presentViewController:socialVc animated:YES completion:nil];
