Added BOOL isMemoryAlmostFull to turn off OpenCV, being not necessary anymore to use its dataClass property in this case. Added method timerFireMethod to turn OpenCV on when it had been previously deactivated by didReceiveMemoryWarning. Deleted “setter” setOpenCVOn, which was used to turn on OpenCV once it had been turned off by didReceiveMemoryWarning. The red rectangle to be drawed on the screen that was within this setter is now within method captureOutput, inside the block of condition that tests dataClass.isOpenCVOn and !isMemoryAlmostFull. Deleted debug UIImageView that showed the photo taken by the camera, also deleted the code to set the image in the image view as the image captured by the camera. The switch that turns OpenCV on and off is now starting turned on. Added a segmentControl on PocketReaderConfigViewController for choosing the language used by the Tesseract. Deleted navigation bar button item and implemented tool bar on top of ViewController. Added Navigation Controller with relationship rootViewController with PocketReaderConfigViewController to add a fix navigation item “Settings”.
