You need to manually transform the table. Here is some code to create and rotate a UITableView around its center.

// this defines a constant PORTRAIT_FRAME, which is the frame of the iPhone screen 
// minus the Status Bar. Equivalent to CGRectMake(0,20,320,460). 
#define PORTRAIT_FRAME [[UIScreen mainScreen] applicationFrame]

// this defines a constant LANDSCAPE_FRAME, for orienting the table sideways
#define LANDSCAPE_FRAME CGRectMake(0,20,480,300)


// this function assumes you have a class variable called myTableView
// and it toggles the orientation of myTableView
- (void) rotateTable {

  if (myTableView.transform == CGAffineTransformMakeRotation(0)) {
    // rotate the image by 90 degrees  
    myTableView.transform = CGAffineTransformMakeRotation(M_PI/2); 
    myTableView.frame = LANDSCAPE_FRAME;
    return;
  }

  // set the image to its original orientation 
  myTableView.transform = CGAffineTransformMakeRotation(0); 
  myTableView.frame = PORTRAIT_FRAME;

}

If you want to trigger this rotation on a button click, then declare a UIButton and assign this function as the action. Here’s a function to create a UIButton. Just pass it @”rotateImage” for the action and self for the target.

+ (UIButton*) getButtonAtPoint:(CGPoint)point 
                             target:(id)target 
                             action:(NSString*)action {

  UIButton *button = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
  [button addTarget:target 
             action:NSSelectorFromString(action)
   forControlEvents:UIControlEventTouchUpInside];
  return button;
}
