iphone - UIVIEWS の円に対して横方向の向きをサポートします。

Question

をサポートしようとしてLandscape orientationいます。以下は描画コードです。注: aCell はUIControlクラスのオブジェクトです:-

- (void)layoutCells 
{
  for ( UIView *aCell in _cells ){
    if ( [aCell superview] != self )
        [self addSubview:aCell];

    int height = [[UIScreen mainScreen] bounds].size.height;
    if (height >= 568)// iPHone  5
    {
        CGRect cellFrame = aCell.frame;
        cellFrame.size.height = 520;
        [aCell setFrame:cellFrame];

        [aCell         setCenter:_spinCenter];
        [[aCell layer] setAnchorPoint:CGPointMake( 0.5, (_spinCenter.y/(self.frame.size.height+70)))];
    }

    else{
            [aCell         setCenter:_spinCenter];
            CGRect frame = CGRectMake(60.f, 424.f, 200.f, 460);
            [[aCell layer] setAnchorPoint:CGPointMake( 0.5, _spinCenter.y/frame.size.height )];
    }
    // Clockifying happens with "selectCellAtIndex:animated:".
  }
}
