I am having a problem where I'm attaching text and a image to the mail composer my textfields attach fine however when i try to attach an image selected from my camera roll i get a question mark? is it because i have not taken a picture from a ios device, and i am just downloading images from google to test it. Also the application works as follows:
user takes picture and sees it in the UIImageView and then can type his contact details and name and send, or can choose a picture from their camera roll.
.h

to take photo use
- (IBAction)takePhotoCam:(id)sender {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
[self.navigationController presentViewController:imagePicker animated:YES completion:nil];
}
To choose from gallery use
- (IBAction)choosePhotoFromLibrary:(id)sender {
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
[self.navigationController presentViewController:imagePicker animated:YES completion:nil];
}
Now use delegate to read that photo and attach in email...
#pragma mark - UIImagePickerControllerDelegate
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
NSData *pngData = UIImagePNGRepresentation(image);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
filePath = [documentsPath stringByAppendingPathComponent:#"myCameraImage.png"];
NSLog(#"saving data at === %#", filePath);
[pngData writeToFile:filePath atomically:YES]; //Write the file
[self.navigationController dismissViewControllerAnimated:YES completion:nil];
}
Now in Documents folder, you have image called myCameraImage.png
Now let's say you have button called Send on email. On clicking create IBAction and attach myCameraImage.png to email.
