No this is not possible, whatsapp does not have any public API you can use.

不，这是不可能的，whatsapp 没有您可以使用的任何公共 API。

Please note that this answer is correct for 2011 when there was no API for WhatsApp.

请注意，当 WhatsApp 没有 API 时，此答案适用于 2011 年。

Now there is an api available for interacting with WhatsApp: http://www.whatsapp.com/faq/en/iphone/23559013

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

The Objective-C call to open one of these URLs is as follows:

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];
}

Is now possible in this way:

现在可以通过这种方式：

Send Text - Obj-C

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
}

Send Text - Swift

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
        }
    }
}

Because a new security feature of iOS 9, you need add this lines on .plistfile:

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

More information about url sheme: https://developer.apple.com/videos/play/wwdc2015-703/

由于 iOS 9 的新安全功能，您需要在.plist文件中添加以下行 ：

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

I did not find a single solution for both. More information on http://www.whatsapp.com/faq/en/iphone/23559013

This is the correct code for share link to whats app users.

这是分享链接到 whats app 用户的正确代码。

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
}

Simple code and Sample code ;-)

简单代码和示例代码 ;-)

Note:- You can only share text or image, both sharing together in whatsApp is not working from whatsApp side

注意：-您只能共享文本或图像，两者在 WhatsApp 中共享在 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];

Yes it's possible :

是的，这是可能的：

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];

Swift 3version for sending text:

用于发送文本的Swift 3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
                }
            }
        }
}

Also, you need to add whatsappto LSApplicationQueriesSchemesin your Info.plist

此外，您需要添加whatsapp到LSApplicationQueriesSchemes您的Info.plist
