UIActivityViewController图像共享不适用于Whatsapp

Question

当我Whatsapp使用UIActivityViewController我正在收到警报时,我正在向app 分享图像数据:

此项目无法共享.请选择其他项目.

我能够将图像数据共享给所有其他应用程序,除了Whatsapp,是否有人遇到过这样的问题？或者任何人都可以帮我解决这个问题.

如果有人想检查代码,那么如果需要,评论将分享.

Answer 1

如果您想使用 WhatsApp 分享图片，请使用以下代码：

if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"whatsapp://app"]]){

        UIImage     * iconImage = [UIImage imageNamed:@"my_account.png"];
        NSString    * savePath  = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wai"];

        [UIImageJPEGRepresentation(iconImage, 1.0) writeToFile:savePath atomically:YES];

        _documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
        _documentInteractionController.UTI = @"net.whatsapp.image";
        _documentInteractionController.delegate = self;

        [_documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated: YES];


    } else {
        UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
    }
