iOS 使用 UIActivityViewController 将图像和 URL 共享到 whatsapp

Question

使用 UIActivityViewController 共享图像和 URL 适用于 facebook 和 gmail，但不适用于 whatsapp。这是我使用的代码

- (void)share {
    UIScreen *screen = [UIScreen mainScreen];
    UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
    UIGraphicsBeginImageContextWithOptions(screen.bounds.size, NO, 0);
    [keyWindow drawViewHierarchyInRect:keyWindow.bounds afterScreenUpdates:YES];
    UIImage *snapShotImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    UIImage *imageToShare = snapShotImage;

    NSURL *urlToShare = [NSURL URLWithString:@"http://google.com"];

    NSMutableArray *activityItems = [NSMutableArray arrayWithObjects:urlToShare, imageToShare, nil];

    UIActivityViewController *activityViewController = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
    activityViewController.excludedActivityTypes = @[
                                                     UIActivityTypePrint,
                                                     UIActivityTypeCopyToPasteboard,
                                                     UIActivityTypeAssignToContact,
                                                     UIActivityTypeSaveToCameraRoll,
                                                     UIActivityTypeAddToReadingList,
                                                     UIActivityTypeAirDrop];


    [self presentViewController:activityViewController animated:YES completion:nil];
}

1. 我错过了什么吗？
2. 我需要为 whatsapp 实现自定义事件吗？

注意:如果是 2，我们需要找到这个 hiding whatsapp from activityviewcontroller继续之前的解决方案

WhatsApp 已更新政策，不允许将简单文本与图像或 URL 或文档一起共享。

如果您尝试分别共享图像和 URL，它将从数组中取出最后一个对象并将其共享。

你可以这样发送图片:

NSMutableArray *activityItems= [NSMutableArray arrayWithObjects:img, nil];
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
activityViewController.excludedActivityTypes = @[UIActivityTypePostToWeibo, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll, UIActivityTypeAddToReadingList, UIActivityTypePostToFlickr, UIActivityTypePostToVimeo, UIActivityTypePostToTencentWeibo, UIActivityTypeAirDrop];    
[self presentViewController:activityViewController animated:YES completion:nil];

此外，您还需要在 iOS9 的 Plist 文件中设置权限

<key>LSApplicationQueriesSchemes</key>
 <array>
  <string>whatsapp</string>
 </array>
