Question

我正在开发iOs 5应用程序（View in App Store），最近在iOs 5上使用本机Twitter集成。我正在使用此代码拍摄应用程序的屏幕截图：

     if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)])
        UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, NO, [UIScreen mainScreen].scale);
    else
        UIGraphicsBeginImageContext(self.view.bounds.size);

    // retrieve the current graphics context
    CGContextRef context = UIGraphicsGetCurrentContext();

    // render view into context
    [self.view.layer renderInContext:context];

    // create image from context
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    // save image to photo album
    UIImageWriteToSavedPhotosAlbum(image,
                                   self,
                                   @selector(image:didFinishSavingWithError:contextInfo:),
                                   @"image.png"); 
 `

我希望用户可以在Twitter上自动分享屏幕截图。为了在Twitter上分享，我正在使用它：

TWTweetComposeViewController *twitter = [[TWTweetComposeViewController alloc] init];
                           [twitter setInitialText:[NSString stringWithFormat:@"Final score %@: %d vs. %@: %d ",intnomlocal, puntsl, intnomvisitant, puntsv]];



 //[twitter addImage:[UIImage imageNamed:@"image"]];
 //[twitter addURL:[NSURL URLWithString:@"http://www.erwinzwart.com"]];



    [self presentViewController:twitter animated:YES completion:nil];

    twitter.completionHandler = ^(TWTweetComposeViewControllerResult res) {

        if(res == TWTweetComposeViewControllerResultDone)
        {

            UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Done!" message:@"Your tweet was send" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];

            [alertView show];


        }else if(res == TWTweetComposeViewControllerResultCancelled)
        {

            UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Cancelled" message:@"Your tweet wasn't send" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];

            [alertView show];

        }

        [self dismissModalViewControllerAnimated:YES];

    };

如何融合这两个代码。我的意思是，当按下按钮时，进行屏幕捕获，保留并在上面的本地Twitter上共享它。感谢!!!

您可以按照现在的顺序将它们放在彼此之下。在addImage: - 方法中，指向image，它应该可以正常工作。您的第一个代码会创建一个UIImage并将其存储到用户的photolibrary中，因此您可以使用下面的twitter代码中的UIImage。
