如何在您的应用程序中截取屏幕截图并将其发布到 Facebook 上？

我试图通过在墙上发布我的应用程序的屏幕截图来在我的应用程序中使用 facebook。

的功能

UIGraphicsBeginImageContext(self.view.bounds.size);
            [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
            UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
            UIGraphicsEndImageContext();

            UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

我已经制作了用于截取屏幕截图和在我的 Facebook 墙上发布带有图标、标题和小描述的内容

- (void)postToWall {


    FBStreamDialog* dialog = [[[FBStreamDialog alloc] init] autorelease];
    dialog.userMessagePrompt = @"Enter your message:";
    dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"%@ share's a photo\",\"href\":\"mywebsite.com/\",\"caption\":\"%@thinks this is a nice photo\",\"description\":\"\",\"media\":[{\"type\":\"image\",\"src\":\"mywebsite.com/icon.png\",\"href\":\"mywebsite.com/\"}]}",
                         _facebookName, _facebookName];

    dialog.actionLinks = @"[{\"text\":\"Get My App\",\"href\":\"http://itunes.apple.com//\"}]"; 
}

。关于如何将我的屏幕截图放入 postToWall 方法中，有什么建议吗？提前致谢！

I'm trying to use facebook within my App by posting a screenshot of my App on my wall.

I already made the functions for taking a screenshot

UIGraphicsBeginImageContext(self.view.bounds.size);
            [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
            UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
            UIGraphicsEndImageContext();

            UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

and for posting stuff on my facebook wall with an icon, title and small description.

- (void)postToWall {


    FBStreamDialog* dialog = [[[FBStreamDialog alloc] init] autorelease];
    dialog.userMessagePrompt = @"Enter your message:";
    dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"%@ share's a photo\",\"href\":\"mywebsite.com/\",\"caption\":\"%@thinks this is a nice photo\",\"description\":\"\",\"media\":[{\"type\":\"image\",\"src\":\"mywebsite.com/icon.png\",\"href\":\"mywebsite.com/\"}]}",
                         _facebookName, _facebookName];

    dialog.actionLinks = @"[{\"text\":\"Get My App\",\"href\":\"http://itunes.apple.com//\"}]"; 
}

Any suggestions of how to put my screenshot within the postToWall method? Thanks in advance!

使用 Facebook 的 iPhone SDK，这是可能的。您需要构建参数块 (NSDictionary) 并将其发送到经过验证的 Facebook 会话。

在此处的代码片段中，“会话”是 SDK 的 Facebook.h 中定义的 Facebook * 类型。

NSMutableDictionary *args = [[[NSMutableDictionary alloc] init] autorelease];
[args setObject:captionText forKey:@"caption"];
[args setObject:messageText forKey:@"message"];
[args setObject:UIImageJPEGRepresentation(yourImage, 0.7) forKey:@"picture"];

[session requestWithMethodName:@"photos.upload" andParams:args ndHttpMethod:@"POST" andDelegate:self];

Using Facebook's SDK for iPhone, it is possible. You will need to construct and argument block (NSDictionary) and send that to the your validated Facebook session.

In the snippet here, "session" is of type Facebook * defined in Facebook.h of the SDK.

NSMutableDictionary *args = [[[NSMutableDictionary alloc] init] autorelease];
[args setObject:captionText forKey:@"caption"];
[args setObject:messageText forKey:@"message"];
[args setObject:UIImageJPEGRepresentation(yourImage, 0.7) forKey:@"picture"];

[session requestWithMethodName:@"photos.upload" andParams:args ndHttpMethod:@"POST" andDelegate:self];
