  [Self.view Addgesturerecognizer:recognizerleft];
  Slide Uiswipegesturerecognizer to the left *recognizerright;
  Recognizerright = [[Uiswipegesturerecognizer alloc] initwithtarget:self action: @selector (handleswipefromright:)];
  [Recognizerright setdirection: (uiswipegesturerecognizerdirectionright)];

[Self.view Addgesturerecognizer:recognizerright]; #pragma-mark-gesture sliding//left sliding-(void) Handleswipefromleft: (Uiswipegesturerecognizer *) recognizer {NSLog (@ "-------into the left hand
