如何通过iOS中的whatsapp分享文字和图片？

Answer 1

不，这是不可能的，whatsapp没有你可以使用的任何公共API。

请注意，当没有WhatsApp的API时，这个答案在2011年是正确的。

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

但是，如果你想要比试试这个现在可以用这种方式：

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
}

发送文字 - 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
        }
    }
}

发送图像 - Obj-C

- 在.h档案

中

<UIDocumentInteractionControllerDelegate>

@property (retain) UIDocumentInteractionController * documentInteractionController;

- 在.m档案

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
        }
    }
}

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>
