ios html5 camera,ios - Allow only access to camera device in HTML5 - Stack Overflow

Write the following takePhoto acton method:

- (IBAction)takePhoto:(UIButton *)sender {

UIImagePickerController *picker = [[UIImagePickerController alloc] init];

picker.delegate = self;

picker.allowsEditing = YES;

picker.sourceType = UIImagePickerControllerSourceTypeCamera;

[self presentViewController:picker animated:YES completion:NULL];

}

Finally, we do the same for the selectPhoto action method, but changing the sourceType to UIImagePickerControllerSourceTypePhotoLibrary.

- (IBAction)selectPhoto:(UIButton *)sender {

UIImagePickerController *picker = [[UIImagePickerController alloc] init];

picker.delegate = self;

picker.allowsEditing = YES;

picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

[self presentViewController:picker animated:YES completion:NULL];

}

Implementing the Delegate Methods of UIImagePickerController

When the user takes a photo with the camera and resizes the image (photo resizing is allowed since we said allowsEditing = YES when we created the image picker). It is a NSDictionary which contains, among other things, the original image and the edited image (accessible through the tag UIImagePickerControllerEditedImage).

(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

UIImage *chosenImage = info[UIImagePickerControllerEditedImage];

self.imageView.image = chosenImage;

[picker dismissViewControllerAnimated:YES completion:NULL];

}
