问题
I have message send functionality in my app and implemented the same using MFMessageComposeViewController. I am able to attach photos with the message in iOS9 but not in iOS 10? Is there anyone having the same issue?

Swift 5.0 version:
Call the below method named displayMessageInterface
:
- Important to note:
composeViewController.addAttachmentData(dataImage!, typeIdentifier: "image/png", filename: "ImageData.png")
In the above line, filename must be of type
abc.png
in my case orabc.jpeg
if you are using a jpeg image data and typeIdentifier must followimage/png
andimage/jpeg
respectively. I struggled a lot to find out this. The reason I write this answer even when other answers are enough already.
For more information on typeIdentifiers, use this link: https://developer.apple.com/library/archive/documentation/Miscellaneous/Reference/UTIRef/Articles/System-DeclaredUniformTypeIdentifiers.html#//apple_ref/doc/uid/TP40009259-SW1
fileprivate func displayMessageInterface() {
if MFMessageComposeViewController.canSendText() {
let composeViewController = MFMessageComposeViewController()
composeViewController.messageComposeDelegate = self
composeViewController.body = "Enter your text body here."
if MFMessageComposeViewController.canSendAttachments() {
let image = UIImage(named: "image-name")!
let dataImage = image.pngData()
guard dataImage != nil else {
return
}
composeViewController.addAttachmentData(dataImage!, typeIdentifier: "image/png", filename: "ImageData.png")
}
self.present(composeViewController, animated: true)
} else {
print("Can't send messages.")
}
}
Since I have mentioned the delegate in the above method, you can use it this way in case of a UIViewController
:
extension UIViewController: MFMessageComposeViewControllerDelegate {
func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) {
if result == .failed {
print("could not send message")
}
self.dismiss(animated: true)
}
}

Please find the below code as image attachment and I had successfully run on iOS 10
.
- (void)sendImgAttachment {
if([MFMessageComposeViewController canSendText]) {
MFMessageComposeViewController *messageController = [[MFMessageComposeViewController alloc] init]; // Create message VC
messageController.messageComposeDelegate = self; // Set delegate to current instance
NSMutableArray *recipients = [[NSMutableArray alloc] init]; // Create an array to hold the recipients
[recipients addObject:@"555-555-5555"]; // Append example phone number to array
messageController.recipients = recipients; // Set the recipients of the message to the created array
messageController.body = @"Example message"; // Set initial text to example message
NSData *dataImg = UIImagePNGRepresentation([UIImage imageNamed:@"logoApple"]);//Add the image as attachment
[messageController addAttachmentData:dataImg typeIdentifier:@"public.data" filename:@"Image.png"];
[self presentViewController:messageController animated:YES completion:NULL];
}
}
Please find the screenshot for the same.
Hope it works for you!!!

i found this solution for me :
if #available(iOS 10.0, *) {
UIApplication.shared.open(URL(string: "sms:123456789")!, options: [:], completionHandler: nil)
} else {
// Fallback on earlier versions
if MFMessageComposeViewController.canSendText() {
if MFMessageComposeViewController.canSendAttachments() {
print("canSendAttachments")
}
let messageVC = MFMessageComposeViewController()
messageVC.body = "Enter a message";
messageVC.recipients = ["123456789"]
messageVC.messageComposeDelegate = self
messageVC.accessibilityActivate()
self.present(messageVC, animated: false, completion: nil)
} else {
print("Cant send sms")
}
}
