在Twitter上分享iOs5的屏幕截图



我正在开发一款iOs 5应用程序(在应用商店中查看),该应用程序最近在iOs 5上与原生Twitter集成。我使用这个代码来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。在Twitter上分享我使用的是:

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];
    };

我怎样才能把这两个代码融合在一起。我的意思是,当按下一个按钮时,进行屏幕捕捉,保留它,并在上面的本地推特上分享。谢谢

您可以按照它们现在的顺序将它们放在一起。在addImage:-方法中,指向image,它应该可以正常工作。您的第一个代码创建了一个UIImage并将其存储到用户的光库中,因此您可以在下面的twitter代码中使用UIImage
