替换工具栏的superview：
buttonDone = [ initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(buttonDoneDown)];
NSArray *itemsArray = ;
UIScrollView *scrollView = [ init];
scrollView.frame = toolbar.frame;
scrollView.bounds = toolbar.bounds;
scrollView.autoresizingMask = toolbar.autoresizingMask;
scrollView.showsVerticalScrollIndicator = false;
scrollView.showsHorizontalScrollIndicator = false;
//scrollView.bounces = false;
UIView *superView = toolbar.superview;
;
toolbar.autoresizingMask = UIViewAutoresizingNone;
toolbar.frame = CGRectMake(0, 0, X, toolbar.frame.size.height);
toolbar.bounds = toolbar.frame;
;
scrollView.contentSize = toolbar.frame.size;
;
;
