在iOS应用中通过WhatsApp分享图片、文本或其他内容是否可行？我在谷歌上搜索，但只发现有关Android实现的结果。

现在可以使用这种方式：
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
}
}
}

整个 "if ([self.delegate respondsToSelector:@selector(imageCompartilhar)]) {" 似乎是多余的。除此之外，它可以正常工作。 - Vaiden
1@vaiden，你说得对关于“if ([self.delegate respondsToSelector: @ selector (imageCompartilhar)]) {”，我是因为我从我的代理那里获取图像。就像“UIImage * iconImage = [_delegate imageCompartilhar];”这样的东西。 - Wagner Sales
1发送消息后是否可以返回应用程序？ - Imran

3谢谢。但是同时分享图像和文本吗？如何返回先前的应用程序？ - Bagusflyer

现在已经可能了。虽然还没有尝试过。
WhatsApp的最新版本说明显示，您可以通过共享扩展实现以下内容：
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）
- 音频备忘录和音乐文件（UTI：public.audio）
- PDF文档（UTI：com.adobe.pdf）
- 联系人卡片（UTI：public.vcard）
- 网页网址（UTI：public.url）

2不可能的，只是打开应用程序，但不能分享图片等等... :) - Rushabh
以上链接很好。现在这是可能的。这应该成为最佳答案。 - Yoav Shapira
2以上链接不允许在不显示菜单的情况下分享媒体到Whatsapp。在前往Whatsapp之前，您必须始终显示文档控制器的菜单，这非常麻烦。 - user3344977
PDF文档（UTI：com.adobe.pdf）->在共享时存在问题。如果我在代码上创建PDF，将其存储在文档目录中并尝试在WhatsApp上共享它，则会失败。我认为WhatsApp想要一种具有Adobe pdf类型的pdf文件，即仅具有UTI com.adobe.pdf。 - Kaan Esin
1@Adel：我们应该如何在UIActivityViewController中设置这个UTI？ - Abhishek Thapliyal

不可能的，WhatsApp没有任何可以使用的公共API。
请注意，这个答案是针对2011年没有WhatsApp API时的情况。
现在有一个可用于与WhatsApp交互的API：http://www.whatsapp.com/faq/en/iphone/23559013
打开其中一个URL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];
}

1现在有没有适用于这个的API？请帮帮我，我已经花了很多时间在这上面。 - SampathKumar
1不，iOS中仍然没有与WhatsApp交互的API。 - rckoenes
1@JHNeves 当我发布我的答案时，这是不可用的。 - rckoenes
请考虑删除此答案或将其扩展为不止一个链接。 - Suragch
有字符限制吗？ - Vaibhav Jhaveri

这是正确的分享链接到Whatsapp用户的代码。
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
}

简单代码和示例代码 ;-)
注意：您只能分享文本或图像，同时在whatsApp中共享两者不起作用
/*
//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];

适用于Swift 4 - 完美运行
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
}
}
}
}
不要忘记用以下行编辑.plist文件
<key>LSApplicationQueriesSchemes</key>
<array>
<string>whatsapp</string>
</array>
祝愉快!!!

1这不会直接打开WhatsApp，而是会打开文档交互视图。有没有办法直接打开WhatsApp？ - DanielZanchi

Wagner Sales的回答的Swift 3版本：
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
}
}
}
