Jeff's solution wasn't quite working for me, but this similar one does: http://charlesharley.com/2013/programming/uibutton-in-uitableviewcell-has-no-highlight-state

In addition to overriding touchesShouldCancelInContentView in your scroll view subclass, you still need to set delaysContentTouches to false. Lastly, you need to return true rather than false for your buttons. Here's a modified example from the above link. As commenters suggested, it checks for any subclass of UIControl rather than UIButton specifically so that this behavior applies to any type of control.

Objective-C:

- (instancetype)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
        self.delaysContentTouches = false;
    }

    return self;
}

- (BOOL)touchesShouldCancelInContentView:(UIView *)view {
    if ([view isKindOfClass:UIControl.class]) {
        return true;
    }

    return [super touchesShouldCancelInContentView:view];
}

Swift 4:

override func touchesShouldCancel(in view: UIView) -> Bool {
    if view is UIControl {
        return true
    }
    return super.touchesShouldCancel(in: view)
}
