如何更改项目的背景颜色，显示我在UIActivityViewController中点击了更多按钮？

Question

Take look at first item

我需要在用户点击UIActivityViewController中的更多按钮后显示的表视图中更改单元格的背景颜色 我调用它的代码：

NSString* title = @"Test";
NSString *link = @"www.testLink.com";
NSArray* dataToShare = @[title, link];

UIActivityViewController* activityViewController =
[[UIActivityViewController alloc] initWithActivityItems:dataToShare
                                  applicationActivities:nil];
[self presentViewController:activityViewController
                       animated:YES
                     completion:nil];
