ios - 如何修复此社交媒体 View 共享 (iOS)？

Question

我的主页上有一个按钮，单击该按钮会弹出一个 subview ，其中显示一些可在社交媒体上分享的选项。到目前为止，我有以下代码:

- (IBAction)showActivityView:(id)sender {
    NSString *shareText = @"The text I am sharing"; 
    //UIImage how can I add an image 
    NSArray *itemsToShare = @[shareText];
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil]; //creating mini view controller that pops up that shows the social options, subclass of view controller
    activityVC.excludedActivityTypes = @[UIActivityTypeAirDrop, UIActivityTypeAssignToContact, UIActivityTypeMail, UIActivityTypePostToTencentWeibo, UIActivityTypePrint, UIActivityTypeCopyToPasteboard];
    [self presentViewController:activityVC animated:YES completion:nil];
}

此功能如我所愿，但我正在尝试弄清楚如何添加图像(第二行)。我以为它会是 UIImage *shareImage = @"img.png"; 但它似乎没有用。我的另一个问题是:有没有一种方法可以让 UIImage 行工作后，我是否可以设置一段代码，在分享之前截取用户的高分，而不是创建状态更新或带有静态图像的推文？

迟到的答案，但这是我用于类似事情的代码:

 //takes screenshot
 UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
    CGRect rect = [keyWindow bounds];
    UIGraphicsBeginImageContextWithOptions(rect.size,YES,0.0f);
    CGContextRef context = UIGraphicsGetCurrentContext();
    [keyWindow.layer renderInContext:context];
    UIImage *capturedScreen = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

 //Share image and text

NSString *text = [NSString stringWithFormat:@"My score"];

UIActivityViewController *controller =
[[UIActivityViewController alloc]
 initWithActivityItems:@[text, capturedScreen]
 applicationActivities:nil];

controller.excludedActivityTypes = @[
                                     UIActivityTypeAssignToContact,
                                     UIActivityTypePostToFlickr,
                                     UIActivityTypePostToVimeo,
                                     UIActivityTypePostToTencentWeibo,
                                     ];

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

希望对您有所帮助。
