【问题描述】：

所以我的应用程序中有一个UIActivityViewController。如何更改背景颜色。 我也有一个快速如何将 Facebook 和 twitter 添加到我的UIActivityViewController 的方法。

守则：

    - (IBAction)Social:(id)sender 
            UIActivityViewController *social = [[UIActivityViewController alloc]initWithActivityItems:[NSArray arrayWithObjects:@"Travel+ Rocks",nil] applicationActivities:nil];
            social.excludedActivityTypes = @[UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypePostToWeibo,UIActivityTypePrint];   
            [self presentViewController:social animated:YES completion:nil];
            [social setCompletionHandler:^(NSString *activityType, BOOL completed)
             
                 NSLog(@"Activity = %@",activityType);
                 NSLog(@"Completed Status = %d",completed);

                 if (completed)
                 
                    // UIAlertView *objalert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Your Posts were sucessful" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                    // [objalert show];
                    // objalert = nil;
                 else
                 
                    // UIAlertView *objalert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Your Posts weren't sucessful" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                    // [objalert show];
                    // objalert = nil;



                 
             ];
        

这些代码修复了后台错误：

NSString *message = [NSString stringWithFormat:@""];
    NSString *textToShare = message;
    UIImage *imageToShare = [UIImage imageNamed:@""];
    NSArray *activityItems = [[NSArray alloc]  initWithObjects:textToShare, imageToShare,nil];
    UIActivity *activity = [[UIActivity alloc] init];
    NSArray *applicationActivities = [[NSArray alloc] initWithObjects:activity, nil];
    UIActivityViewController *activityVC =
    [[UIActivityViewController alloc] initWithActivityItems:activityItems
    applicationActivities:applicationActivities];
    [self presentViewController:activityVC animated:YES completion:nil];

如果您设置了目标 -> 摘要 -> 状态栏样式，则共享视图的颜色将跟随。最好的 iv 发现了.....
