如何在iphone上的whatsapp上共享图像+文本标题（URL）？ [英] How Can I share image +text caption(URL) on whatsapp from iphone?

问题描述

我在WhatsApp上使用了以下代码来共享图像，但我无法使用以下代码设置标题文本。

我尝试了<$ c的注释属性$ c> UIDocumentInteractionController ，但是在WhatsApp开发者表单中没有为注释指定任何键。

我知道我们可以做到通过使用 UIImageGraphicContext ，但我需要共享URL作为标题

  if （[[UIApplication sharedApplication] canOpenURL：[NSURL URLWithString：@whatsapp：// app]]）
 {
 NSString * savePath = [NSHomeDirectory（）stringByAppendingPathComponent：@Documents / whatsAppTmp.wai ]。 
 
 [UIImageJPEGRepresentation（[UIImage imageNamed：@Convenor- image-SURANA1.png]，1.0）writeToFile：savePath atomically：YES]; 
 
 _documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL：[NSURL fileURLWithPath：savePath]]; 
 _documentInteractionController.annotation = [NSDictionary dictionaryWithObject：@wwww.google.comforKey：@whatsappCaption]; 
 
 _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：@Alert。消息：@Por favor，instale Whatsapp。 delegate：nil cancelButtonTitle：@EstábemotherButtonTitles：nil]; 
 [alert show]; 
} 
  

解决方案

你不能预先填写标题在whatsapp上分享图像。 Facebook已经从Facebook，Instagram上弃用了这个功能。

你可以发送文字或图像。但是无法以编程方式预填标题。

问题中的代码可以很好地发送图像。要发送纯文本，您可以使用下面提到的链接的参考：

I have used following code for share image on WhatsApp but I am unable to set the caption text using following code.

I have tried annotation property of UIDocumentInteractionController,But in WhatsApp developer form there is not any key is specified for annotation.

I do know that we can do it by using UIImageGraphicContext, But I need to share URL as caption

if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"whatsapp://app"]])
{
    NSString * savePath  = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wai"];

    [UIImageJPEGRepresentation([UIImage imageNamed:@"Convenor- image-SURANA1.png"], 1.0) writeToFile:savePath atomically:YES];

    _documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
    _documentInteractionController.annotation = [NSDictionary dictionaryWithObject:@"wwww.google.com" forKey:@"whatsappCaption"];

    _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:@"Alert." message:@"Por favor, instale Whatsapp." delegate:nil cancelButtonTitle:@"Está bem" otherButtonTitles:nil];
    [alert show];
}

解决方案

You cannot pre-fill caption while sharing image on whatsapp. Facebook has already deprecated this functionality from Facebook, Instagram also.

You can either send a text or an image. But programmatically pre-filling caption is not possible.

The code in the question is fine to send an image. In order to send a plain text you can use the reference of below mentioned link:

NOTE: Setting caption programmatically is not possible.

Hope this helps!
