我正在使用以下代码在我的 iPhone 上截屏并将其保存到相册中。我想要一个分享按钮来自动将此屏幕截图发送到 Facebook。有没有人有任何想法如何实施？

- (UIImage*)captureView:(UIView *)view
{
CGRect rect = [[UIScreen mainScreen] bounds];
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
[view.layer renderInContext:context];
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return img;
}

- (void)saveScreenshotToPhotosAlbum:(UIView *)view
{
UIImageWriteToSavedPhotosAlbum([self captureView:self.view], nil, nil, nil);
}

- (void)viewDidLoad
{
[super viewDidLoad];
[self setUpData];

CGRect frame = self.view.bounds;
frame.size.height -= 90;

self.tableView = [[UITableView alloc] initWithFrame:frame style:UITableViewStylePlain];
[self.tableView setBackgroundColor:[UIColor clearColor]];
[self.tableView setDataSource:self];
[self.tableView setDelegate:self];

[self.view addSubview:self.tableView];

UIBarButtonItem *shareBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(saveScreenshotToPhotosAlbum:)];
[self.navigationItem setRightBarButtonItem:shareBtn];

}

好吧，你可以使用iOS6 内置的Facebook 集成。Social将框架包含在Build Phases 代码中应该看起来与此片段相似：

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]){
    mySLComposerSheet = [[SLComposeViewController alloc] init];
    mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
    [mySLComposerSheet setInitialText:@"Some Text"];
    [mySLComposerSheet addImage:[self captureView:self.view]];
    [self presentViewController:mySLComposerSheet animated:YES completion:nil];
}

*请注意，这不会“自动”共享屏幕截图，但会将其附加到 Facebook Compose Sheet，用户可以根据需要发布。要自动执行此操作，您需要进行更深入的 Facebook 集成，并且用户应允许您的应用在他/她的墙上发布。这应该再次使用Social框架完成，或者ShareKit如果项目Deployment target低于 iOS 6.0
