Is there a way to hide the scroll indicators in a UIScrollView?

Set the showsHorizontalScrollIndicator and showsVerticalScrollIndicator properties of the UIScrollView to NO.

[tableView setShowsHorizontalScrollIndicator:NO];
[tableView setShowsVerticalScrollIndicator:NO];

Documentation - UIScrollView

//For UITableView - Objective-C

tbl.showsHorizontalScrollIndicator = NO;
tbl.showsVerticalScrollIndicator = NO;

//For UITableView - SWIFT 3.0

tbl.showsHorizontalScrollIndicator = false
tbl.showsVerticalScrollIndicator = false

//For UIScrollView - Objective-C

scrl.showsHorizontalScrollIndicator = NO;
scrl.showsVerticalScrollIndicator = NO;

//For UIScrollView - SWIFT

scrl.showsHorizontalScrollIndicator = false
scrl.showsVerticalScrollIndicator = false

Change from XIB or storyboard
