I want to share an image via whatsapp.
I'm using UIDocumentInteractionController with the following code.
Can I skip the menu that is opened (and the user selects whatsapp) and just act as if he selected the first option?
if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:#"whatsapp://app"]])
{
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/whatsAppTmp.wai"];
[UIImageJPEGRepresentation(image, 1.0) writeToFile:savePath atomically:YES];
_documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
_documentInteractionController.UTI = #"net.whatsapp.image";
_documentInteractionController.delegate = self;
[_documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated: YES];
}
WhatsApp was updated with iOS 8 SDK with ShareKit extension.
So now sharing to WhatsApp is 'default' in UIActivityController and there is no need to implement UIDocumentInteractionController to share the image.

I'm developping share image to the other apps, including WhatsApp.
I'm using this code and it works.
if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:#"whatsapp://app"]]){
UIImage *image = [self processImage:sender];
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/whatsAppTmp.wai"];
[UIImageJPEGRepresentation(image, 1.0) writeToFile:savePath atomically:YES];
_documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
_documentInteractionController.delegate = self;
_documentInteractionController.UTI = #"net.whatsapp.image";
[_documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
}else {
[self showAlertTitle:#"WhatsApp not installed." message:#"Your device has no WhatsApp installed."];
}
The problem is, when I run this code, documentInteractionController presents the other options apps like this image, so I must pick WhatsApp first before it open WhatsApp application.
Can I select Whatsapp App to share the file without presenting the menu for choosing? In other words, can I avoid presentOpenInMenuFromRect ?
I`m using iOS 9 and this issue happen also with my Instagram post
Yes. you can write this code. After run code do the following.
Step:1 Add LSApplicationQueriesSchemes in Info.plist
Step:2 Add whatsapp in items.
It successfully redirects to the Whatsapp app.There is no preview frame and when tapped Send, an error messages pops up "This video could not be sent. Please choose a different video.
Here is my code.
- (void)shareVideo {
NSLog(#"[WhatsAppShare] sharing video");
//NSString *nativePath = [[NSString alloc] initWithCString:path encoding:NSASCIIStringEncoding];
NSString *nativePath=[[NSBundle mainBundle] pathForResource:#"video" ofType:#"mp4"];
// Save video to path in documents directory
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/whatsAppTmp.wam"];
if([[NSFileManager defaultManager] fileExistsAtPath:savePath]){
if([[NSFileManager defaultManager] removeItemAtPath:savePath error:nil]){
[self shareVideoAtNativePath:nativePath SavePath:savePath];
}
} else {
[self shareVideoAtNativePath:nativePath SavePath:savePath];
}}
- (void)shareVideoAtNativePath:(NSString*)nativePath SavePath:(NSString*)savePath{
NSError*error;
BOOL isSuccess=[[NSFileManager defaultManager] copyItemAtPath:nativePath toPath:savePath error:&error];
if(isSuccess){
// Create interaction controller
self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
self.documentInteractionController.UTI = #"net.whatsapp.movie";
self.documentInteractionController.delegate = self;
[self.documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 1, 1)
inView:[self view]
animated:YES];
} else{
NSLog(#"error %#", error);
}
}
We have observed the exact same problem. Everything was working until a recent update of WhatsApp. This is probably a bug on WhatsApp side.
Here is a workaround for this problem:
Do not use a wam file, use the mp4 file directly. So in your case, just call
[self shareVideoAtNativePath:nativePath SavePath:nativePath];
Change the UTI to public Mpeg4:
self.documentInteractionController.UTI = #"public.mpeg-4";
This seems to have solved our issue. However, there is a drawback that, the share dialog now contains many other apps/services that can open mp4 files.
We've faced the exact same issue.
The official .wam format brings up only WhatsApp in the share dialog, but fails to forward the video.
Using .m4v format is working for us. A few more options are displayed along with WhatsApp (Open in WhatsApp is the option we want). We are displaying an alert saying "Please select Whatsapp on the next screen" before sending user to the share dialog.
File format: m4v
UTI: net.whatsapp.movie
Please refer to the working code below:
UIDocumentInteractionController *documentInteractionController;
-----
-----
- (void)shareVideoViaWhatsApp:(NSURL*)url{
// Creating temp video to share specifically on whatsapp.
NSString *cachesFolder = [NSTemporaryDirectory() stringByAppendingPathComponent: [NSString stringWithFormat:#"video.m4v"]];
NSURL *file = [NSURL fileURLWithPath:cachesFolder];
[[NSData dataWithContentsOfURL:url] writeToURL:file options:NSDataWritingAtomic error:nil];
documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL: file ];
documentInteractionController.UTI = #"net.whatsapp.movie";
documentInteractionController.delegate = self;
[documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
}
// In code Use share GIF and Video for WhatsApp....
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/whatsAppTmp.wam"];
savePath = [[NSBundle mainBundle] pathForResource:#"Movie" ofType:#"m4v"];
_documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:_videourl];
_documentInteractionController.UTI = #"net.whatsapp.movie";
_documentInteractionController.delegate = (id)self;
[_documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated: YES];
Hi this is my code to open Instagram App directly with an image. As stated in Apple document relative to UIDocumentInteractionController and in Instagram hook page this snippet of code should open instagram directly with the image, but in all testing conditions it open the action sheet with all the app compatible with the extension saved.
I've also whitelisted instagram in LSApplicationQueriesSchemes.
How can i achive this result? It's a bug or a new security feature of IOS 9?
Thanks in advance for your help
NSURL *instagramURL = [NSURL URLWithString:#"instagram:/"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:#"savedImage.ig"];
[UIImagePNGRepresentation(capturedImage) writeToFile:getImagePath atomically:YES];
NSURL *imageFileURL =[NSURL fileURLWithPath:getImagePath];
NSLog(#"imag %#",imageFileURL);
self.dic.delegate = self;
self.dic.UTI = #"com.instagram.photo";
self.dic = [self setupControllerWithURL:imageFileURL usingDelegate:self];
[self.dic presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
} else //prompt for app missing
- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL
usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
UIDocumentInteractionController *interactionController =
[UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
if you save the image as .igo the only apps i see in the actionsheet are "Instagram" "Notes" and "other.
edit: I have't found a way to open Instagram directly with an image it only seems possible to open it directly with
NSURL *instagramURL = [NSURL URLWithString:#"instagram://location?id=1"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
[[UIApplication sharedApplication] openURL:instagramURL];
}
but you can't add an image with that
edit2: I forgot to add that for the .igo format you need to use self.dic.UTI = "com.instagram.exclusivegram"
On iOS 7.1.1, I can share image by this code on Whatsapp..
if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:#"whatsapp://app"]]){
UIImage * iconImage = [UIImage imageNamed:#"image.png"];
NSString * savePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/whatsAppTmp.wai"];
[UIImageJPEGRepresentation(iconImage, 1.0) writeToFile:savePath atomically:YES];
self.docController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
self.docController.UTI = #"net.whatsapp.image";
self.docController.delegate = self;
//[self.docController setAnnotation:#{#"WhatsappCaption" : #"https://itunes.apple.com/us/app/epic-ar/id535122470?ls=1&mt=8"}];
[self.docController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:appDelegate.window.rootViewController.view animated: YES];
}
But I want to share video too, I follow tutorial on Wahtsapp tutorial
But How can be the code of video path ?
I mean, What is the alternative object of UIImage object to display video ?
Also, can I share "Link" ?
Thank you,
It took me a while, but I put the pieces together
references: Share image/text through WhatsApp in an iOS app

//---NEXT LINE OF CODE IS OPTIONAL AND NOT RECOMMENDED, BUT YOU CAN USE IT TO TEST TO SEE IF THEY HAVE THE WHATSAPP INSTALLED
// if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:#"whatsapp://app"]]){
NSString * savePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/whatsAppTmp.wam"];
savePath = [[NSBundle mainBundle] pathForResource:#"Movie" ofType:#"m4v"];

This is only to answer your main question: Share video on whatsapp
I need to have Facebook and WhatsApp as sharing options for my image. I've already implemented UIActivityViewController, where i can share via Facebook and UIDocumentInteractionController where i can share via WhatsApp. I don't know how to merge these things.
UIActivityViewController:
UIActivityViewController *activityViewContoller = [[UIActivityViewController alloc]
initWithActivityItems:#[#"Test", image] applicationActivities:nil];
[self presentViewController:activityViewContoller animated:YES completion:nil];
UIDocumentInteractionController:
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/whatsAppTmp.wai"];
[UIImageJPEGRepresentation(image, 1.0) writeToFile:savePath atomically:YES];
_documentInteractionController = [UIDocumentInteractionController
interactionControllerWithURL:[NSURL fileURLWithPath:savePath]];
_documentInteractionController.UTI = #"net.whatsapp.image";
_documentInteractionController.delegate = self;
[_documentInteractionController presentOpenInMenuFromRect:CGRectZero
inView:self.view animated:YES];
I want to have both of them in one popover, however I have no idea how to achieve it. Any tip please?
I've checked out StackOverFlow question 1, but it doesn't help me at all. My file is .wai (for WhatsApp) so when i try to send it via FB file is unable to open. Also it shows all options, while i want only 2(FB+WhatsApp) to be visible. Following the StackOverFlow question 2 I can show only FB (working one, because i set normal image) but can't add WhatsApp (no .wai file, i don't know what to do with UTI). Is there any way to solve this issue?
To change type of file:
- (void)share {
NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/tmptmpimg.jpg"];
[UIImageJPEGRepresentation(_img, 1.0) writeToFile:path atomically:YES];
_documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path]];
_documentInteractionController.delegate = self;
[_documentInteractionController presentOptionsMenuFromRect:CGRectZero inView:self.view animated:YES];
}
- (void)documentInteractionController:(UIDocumentInteractionController *)controller willBeginSendingToApplication:(NSString *)application {
if ([self isWhatsApplication:application]) {
NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/tmptmpimg.wai"];
[UIImageJPEGRepresentation(_img, 1.0) writeToFile:savePath atomically:YES];
controller.URL = [NSURL fileURLWithPath:savePath];
controller.UTI = #"net.whatsapp.image";
}
}
- (BOOL)isWhatsApplication:(NSString *)application {
if ([application rangeOfString:#"whats"].location == NSNotFound) { // unfortunately, no other way...
return NO;
} else {
return YES;
}
}
This way we can use all options- Facebook, Twitter and custom WhatsApp.
The problem with showing only selected options is still not solved, but it's the minor one.
To exclude non-desired sharing options (the second part of your question), assuming your UIActivityViewController object is called activityController, set the excludedActivityTypes property, like so:
activityController.excludedActivityTypes = #[UIActivityTypeAssignToContact,
UIActivityTypePrint,
UIActivityTypeAddToReadingList,
UIActivityTypeAirDrop];
