【发布时间】：2012-01-11 08:52:15
【问题描述】：

是否可以通过 iOS 应用程序中的 Whatsapp 共享图像、文本或任何您想要的内容？我在谷歌上搜索，但我只找到了关于 Android 实现的结果。

标签： iphone ios

【解决方案1】：

现在可以通过这种方式：

发送文本 - Obj-C

NSString * msg = @"YOUR MSG";
NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",msg];
NSURL * whatsappURL = [NSURL URLWithString:[urlWhats stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
    [[UIApplication sharedApplication] openURL: whatsappURL];
} else {
    // Cannot open whatsapp
}

发送文本 - Swift

let msg = "YOUR MSG"
let urlWhats = "whatsapp://send?text=\(msg)"
if let urlString = urlWhats.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet()) {
    if let whatsappURL = NSURL(string: urlString) {
        if UIApplication.sharedApplication().canOpenURL(whatsappURL) {
            UIApplication.sharedApplication().openURL(whatsappURL)
        } else {
            // Cannot open whatsapp
        }
    }
}

发送图片 - Obj-C

-- 在 .h 文件中

<UIDocumentInteractionControllerDelegate>

@property (retain) UIDocumentInteractionController * documentInteractionController;

-- 在 .m 文件中

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

    UIImage     * iconImage = [UIImage imageNamed:@"YOUR IMAGE"];
    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];
}

发送图片 - Swift

let urlWhats = "whatsapp://app"
if let urlString = urlWhats.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet()) {
    if let whatsappURL = NSURL(string: urlString) {

        if UIApplication.sharedApplication().canOpenURL(whatsappURL) {

            if let image = UIImage(named: "image") {
                if let imageData = UIImageJPEGRepresentation(image, 1.0) {
                    let tempFile = NSURL(fileURLWithPath: NSHomeDirectory()).URLByAppendingPathComponent("Documents/whatsAppTmp.wai")
                    do {
                        try imageData.writeToURL(tempFile, options: .DataWritingAtomic)
                        self.documentInteractionController = UIDocumentInteractionController(URL: tempFile)
                        self.documentInteractionController.UTI = "net.whatsapp.image"
                        self.documentInteractionController.presentOpenInMenuFromRect(CGRectZero, inView: self.view, animated: true)
                    } catch {
                        print(error)
                    }
                }
            }

        } else {
            // Cannot open whatsapp
        }
    }
}

因为 iOS 9 的一个新的安全特性，你需要添加这行 .plist 文件：
<key>LSApplicationQueriesSchemes</key>
 <array>
  <string>whatsapp</string>
 </array>

【讨论】：

whatsapp 可以与安卓应用集成
@vaiden，你是对的“if ([self.delegate respondsToSelector: @ selector (imageCompartilhar)]) {”因为我得到了我的代表的形象。类似“UIImage * iconImage = [_delegate imageCompartilhar];”
消息发送后是否可以返回应用
我们可以同时发送（文本和图像）吗？
谢谢。但同时分享图片和文字？以及如何返回之前的申请。

【解决方案2】：

现在可以了。不过还没试过。

最新release notes for whatsapp表示可以通过分享扩展：

WhatsApp 接受以下类型的内容：

文本（UTI：public.plain-text）
照片（UTI：public.image）
视频（UTI：public.movie）
音频笔记和音乐文件 (UTI: public.audio)
PDF 文档 (UTI: com.adobe.pdf)
联系人卡片（UTI：public.vcard）
网址（UTI：public.url）

【讨论】：

不可能，它只打开应用程序但不分享图像等...:)
上面的链接不错。现在这是可能的。这应该成为最佳答案。
以上链接不允许在不显示菜单的情况下将媒体共享到 Whatsapp。在访问 Whatsapp 之前，您必须始终显示文档控制器的菜单，这很麻烦。
PDF 文档 (UTI: com.adobe.pdf) -> 共享时出现问题。如果我在代码上创建 pdf，将其存储在 documentdirectory 上并尝试在 whatsapp 上共享它，它会失败。我认为whatsapp想要一个具有Adobe pdf类型的pdf文件，即只有UTI com.adobe.pdf
@Adel：我们如何在 UIActivityViewController 中设置这个 UTI？？？？

【解决方案3】：

~~不，这是不可能的，whatsapp 没有任何你可以使用的公共 API。~~

请注意，这个答案在 2011 年是正确的，当时没有 WhatsApp 的 API。

现在有一个可用于与 WhatsApp 交互的 api：http://www.whatsapp.com/faq/en/iphone/23559013

打开这些 URL 之一的 Objective-C 调用如下：

NSURL *whatsappURL = [NSURL URLWithString:@"whatsapp://send?text=Hello%2C%20World!"];
if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
    [[UIApplication sharedApplication] openURL: whatsappURL];
}

【讨论】：

现在有这方面的 api，请帮帮我，我花了更多时间在这方面
不，在 iOS 中仍然没有与 WhatsApp 交互的 API。
您可以使用 url 方案与 whatsapp 应用程序交谈！请参阅@Wagner Sales 的答案。
@JHNeves 当我发布我的答案时，这是不可用的。
考虑删除此答案或将其扩展为不止一个链接。

【解决方案4】：

这是与whats app用户分享链接的正确代码。

NSString * url = [NSString stringWithFormat:@"http://video...bla..bla.."];
url =    (NSString*)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef) url, NULL,CFSTR("!*'();:@&=+$,/?%#[]"),kCFStringEncodingUTF8));

  NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",url];
NSURL * whatsappURL = [NSURL URLWithString:urlWhats];
if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
    [[UIApplication sharedApplication] openURL: whatsappURL];
} else {
    // can not share with whats app
}

【讨论】：

【解决方案5】：

简单代码和示例代码 ;-)

注意：- 你只能分享文字或图片，在whatsApp中一起分享在whatsApp端不起作用

 /*
    //Share text
    NSString *textToShare = @"Enter your text to be shared";
    NSArray *objectsToShare = @[textToShare];
    
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
    [self presentViewController:activityVC animated:YES completion:nil];
     */
    
    //Share Image
    UIImage * image = [UIImage imageNamed:@"images"];
    NSArray *objectsToShare = @[image];
    
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
    [self presentViewController:activityVC animated:YES completion:nil];

Swift 3 版本的 Wagner Sales 的回答：

let urlWhats = "whatsapp://app"
if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed) {
  if let whatsappURL = URL(string: urlString) {
    if UIApplication.shared.canOpenURL(whatsappURL) {

      if let image = UIImage(named: "image") {
        if let imageData = UIImageJPEGRepresentation(image, 1.0) {
          let tempFile = NSURL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents/whatsAppTmp.wai")
          do {
            try imageData.write(to: tempFile!, options: .atomic)

            self.documentIC = UIDocumentInteractionController(url: tempFile!)
            self.documentIC.uti = "net.whatsapp.image"
            self.documentIC.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: true)
          }
          catch {
            print(error)
          }
        }
      }

    } else {
      // Cannot open whatsapp
    }
  }
}

对于 Swift 4 - 工作正常

声明

var documentInteractionController:UIDocumentInteractionController!

func sharePicture() {
    let urlWhats = "whatsapp://app"
    if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: NSCharacterSet.urlQueryAllowed) {
        if let whatsappURL = NSURL(string: urlString) {

            if UIApplication.shared.canOpenURL(whatsappURL as URL) {

                let imgURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
                let fileName = "yourImageName.jpg"
                let fileURL = imgURL.appendingPathComponent(fileName)
                if let image = UIImage(contentsOfFile: fileURL.path) {
                    if let imageData = image.jpegData(compressionQuality: 0.75) {
                        let tempFile = NSURL(fileURLWithPath: NSHomeDirectory()).appendingPathComponent("Documents/yourImageName.jpg")
                        do {
                            try imageData.write(to: tempFile!, options: .atomicWrite)
                            self.documentInteractionController = UIDocumentInteractionController(url: tempFile!)
                            self.documentInteractionController.uti = "net.whatsapp.image"
                            self.documentInteractionController.presentOpenInMenu(from: CGRect.zero, in: self.view, animated: true)
                        } catch {
                            print(error)
                        }
                    }
                }
            } else {
                // Cannot open whatsapp
            }
        }
    }
}

不要忘记使用以下行编辑 .plist

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

享受！！！

是的，有可能：

NSMutableArray *arr = [[NSMutableArray alloc]init];
    NSURL *URL = [NSURL fileURLWithPath:path];
    NSString *textToShare = [NSString stringWithFormat:@"%@ \n",_model.title];
    NSString *SchoolName= [[AppUtility sharedUtilityInstance]getAppConfigInfoByKey:@"SchoolName" SecondKeyorNil:Nil];
    [arr addObject:textToShare];
    [arr addObject:URL];
    [arr addObject:_model.body];
    [arr addObject:SchoolName];
    TTOpenInAppActivity *openInAppActivity = [[TTOpenInAppActivity alloc] initWithView:_parentController.view andRect:((UIButton *)sender).frame];

    UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:arr applicationActivities:@[openInAppActivity]];

    // Store reference to superview (UIActionSheet) to allow dismissal
    openInAppActivity.superViewController = activityViewController;
    // Show UIActivityViewController
    [_parentController presentViewController:activityViewController animated:YES completion:NULL];

【讨论】：

图片和文字是否共享？

【解决方案11】：

Swift 3 用于发送文本的版本：

func shareByWhatsapp(msg:String){
        let urlWhats = "whatsapp://send?text=\(msg)"
        if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) {
            if let whatsappURL = NSURL(string: urlString) {
                if UIApplication.shared.canOpenURL(whatsappURL as URL) {
                    UIApplication.shared.openURL(whatsappURL as URL)
                } else {

                    let alert = UIAlertController(title: NSLocalizedString("Whatsapp not found", comment: "Error message"),
                                                  message: NSLocalizedString("Could not found a installed app 'Whatsapp' to proceed with sharing.", comment: "Error description"),
                                                  preferredStyle: UIAlertControllerStyle.alert)

                    alert.addAction(UIAlertAction(title: NSLocalizedString("Ok", comment: "Alert button"), style: UIAlertActionStyle.default, handler:{ (UIAlertAction)in
                    }))

                    self.present(alert, animated: true, completion:nil)
                    // Cannot open whatsapp
                }
            }
        }
}

另外，您需要在Info.plist 中将whatsapp 添加到LSApplicationQueriesSchemes

你需要添加一些解释。为什么你认为这段代码有效？与之前的答案有何不同？
