是否可以通过Whatsapp在iOS应用中分享图片，文字或其他任何内容？我正在谷歌上搜索，但我只发现了有关Android实现的结果。
答案 0 :(得分：122)
现在可以这样：
发送文字 - 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
}
}
}
由于iOS 9的新安全功能，您需要添加此行 .plist 文件：
<key>LSApplicationQueriesSchemes</key> <array> <string>whatsapp</string> </array>有关网址的更多信息：https://developer.apple.com/videos/play/wwdc2015-703/

现在可以了。虽然还没试过。
最新release notes for whatsapp表示您可以通过共享扩展程序：
WhatsApp接受以下类型的内容：
答案 2 :(得分：19)
这不可能，whatsapp没有你可以使用的任何公共API。
请注意，当没有WhatsApp的API时，2011年的答案是正确的。
现在有一个api可用于与WhatsApp交互：http://www.whatsapp.com/faq/en/iphone/23559013
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];
}
答案 3 :(得分：8)
这是与应用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
}

是的，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];

Swift 3 version for sending text:
?- cantNodos(arbol(3,arbol(2,nil,nil),arbol(6,nil,arbol(8,nil,nil))),R).
R=4.
Also, you need to add SFTP_VAR="JHGSYDDUIGUIGUIGUIG" to # Incorrect
SFTP_VAR="*"; export SSHPASS=$SFTP_VAR; echo $SSHPASS
# Correct
SFTP_VAR="*"; export SSHPASS="$SFTP_VAR"; echo "$SSHPASS"
in your 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
}
}
}
}

对于Swift 4-正常工作
delclare
--source_path不要忘记用以下几行来编辑.plist
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)
}
}

// Cannot open whatsapp
