UIScrollView indicator always show?

问题:

Thank you.

You can't. This is part of the interface guidelines. What you can do alternatively is flash them in some sensible circumstances (the view becomes visible, moves onto the screen, or similar) using the - (void)flashScrollIndicators method.

You can use this custom scroll bar:

To always show the scroll bar you just need to do this:

brScrollBar =[BRScrollBarController initForScrollView:self.tableView
                                               onPosition:kIntBRScrollBarPositionRight
                                                 delegate:self];
brScrollBar.scrollBar.hideScrollBar = NO;

The scroll bar has many features, and its draggable.
