title: How to implement custom 'Use' and 'Retake' button in UIImagePicker?
body: <p>I have a switched the cameracontrolls off, i mean</p>
  
  <pre>pickerCam.showsCameraControls=NO;</pre>
  
  <p>and i have custom capture button which does the capture functionality,</p>
  
  <pre>[pickerCam takePicture];</pre>
  
  <p>on click of this button the delegate will be called,</p>
