I am currently developing an application and I need to be able when pressing a button to open the camera and take a snapshot that I will attach to a .json file and send to my server. I am searching on google and StackOverflow for the last couple of hours but all the tutorials seem very old (08'-09') or not match my needs. I know that all the work is done with UIImagePickerController class but I would like to have a working example. Does anyone know a good tutorial to get started for something like this?

回答1:

Well if you google something like:

UIImagePickerController and take snapshot put in json and send to server

Will be a bit hard. So, use this tutorial for the UIImagePickerController. By the way, the term for the search was:

You should check this article from AppCoda Build a Simple iPhone Camera App, very clear and simple :)

Take photo using the native iOS Camera app

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

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;

    [self presentViewController:picker animated:YES completion:nil]; 
}

Read the captured photo (you have to implement UIImagePickerControllerDelegate

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

    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    self.imageView.image = chosenImage;

    [picker dismissViewControllerAnimated:YES completion:nil];
}

I came across this code AQPhotoPicker. This is quite easy to use with only one call, you will get photo from camera or photoPicker

Try this. It's very simple, you just need to set delegate for a controller and call it. Google will help you, there are plenty of resources and working examples. For instance, sample code from Apple
