How to add scrolling for buttons on UIToolbar?

How to add scrolling for UIBarButtonItem buttons on UIToolbar (to place many buttons on the toolbar)?

buttonDone = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(buttonDoneDown)];
NSArray *itemsArray = [NSArray arrayWithObjects:buttonDone, nil];
[toolbar setItems:itemsArray];

Thanks a lot for the help!

Solution

  • Replace superView of the toolbar:

    buttonDone = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(buttonDoneDown)];
NSArray *itemsArray = [NSArray arrayWithObjects:buttonDone, nil];

UIScrollView *scrollView = [[UIScrollView alloc] 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 removeFromSuperview];
toolbar.autoresizingMask = UIViewAutoresizingNone;
toolbar.frame = CGRectMake(0, 0, X, toolbar.frame.size.height);
toolbar.bounds = toolbar.frame;
[toolbar setItems:itemsArray];
scrollView.contentSize = toolbar.frame.size;
[scrollView addSubview:toolbar];
[superView addSubview:scrollView];
