How to automatically take a picture without pressing the phototaken button on the imagepickercontroller?

Question

In my project, I need to take pictures automatically every one minute. But I can\'t find out any solutions.

This is the code which I implemented but it doesn\'t work

Answer 1

You can call the method - (void)takePicture; of UIImagePickerController to take a picture programmatically. You can call it every one minute using a timer for example.

Edit

You should display the camera interface first (more info here). You can do this in the method showCameraUI. You should also keep a reference to the created UIImagePickerController.

- (IBAction) showCameraUI
{
    UIImagePickerController *picker;
    // create and display picker

   self.imagePicker = imagePicker;
   [NSTimer scheduledTimerWithTimeInterval:4.0
                             target:self
                           selector: @selector(targetMethod)
                           userInfo:nil
                            repeats:YES];
}

- (void)targetMethod
{
    [self.picker takePicture];
    // ...
}
