在iOS 9中通过WhatsApp共享字符串+图片

Question

在iOS 9+Xcode7.3中通过WhatsApp共享字符串+图像，出现错误。iOS 8运行良好。代码：

UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil];

    NSArray *excludeActivities = @[UIActivityTypePrint,
                                   UIActivityTypeCopyToPasteboard,
                                   UIActivityTypeAssignToContact,
                                   UIActivityTypeSaveToCameraRoll,
                                   UIActivityTypeAddToReadingList,
                                   UIActivityTypeAirDrop];

    activityController.excludedActivityTypes = excludeActivities;

    [activityController setValue:[NSString stringWithFormat:@"Test msg"] forKey:@"subject"];

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

Answer 1

在iOS 9中，您需要在项目.plist文件中添加以下行：

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

在.plist中添加此代码后进行检查。

我用下面的代码解决了问题：

- (id)activityViewControllerPlaceholderItem:(UIActivityViewController *)activityViewController
{
    return @"";
}

- (id)activityViewController:(UIActivityViewController )activityViewController itemsForActivityType:(NSString )activityType
{

    if ([activityType isEqualToString:@"net.whatsapp.WhatsApp.ShareExtension"]) {

        NSString *strShare = @“Test string”;

        NSString *string = [NSString stringWithFormat:@"whatsapp://send?text=%@",strShare];
        NSURL *url = [NSURL URLWithString:[string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
        [[UIApplication sharedApplication] openURL: url];

        return @"";

    }
    else
    {
        return  sharingItems;
    }
}

您可以添加图像url，因为共享图像是不可能的。

NSArray *arrData = @[@"Post Title", @"imageURL"];
UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:arrData applicationActivities:nil];
NSArray *excludeActivities = @[UIActivityTypeAirDrop,
                               UIActivityTypePrint,
                               UIActivityTypeAssignToContact,
                               UIActivityTypeSaveToCameraRoll,
                               UIActivityTypeAddToReadingList];
activityVC.excludedActivityTypes = excludeActivities;

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