- Super Fancy animations
DMScrollBar is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'DMScrollBar', '~> 1.0.0'and run
pod installOn any ScrollView you want to add the ScrollBar with default configuration, just call (see result on Gid #2):
scrollView.configureScrollBar()If you want to provide title for info label, implement DMScrollBarDelegate protocol on your ViewController:
extension ViewController: DMScrollBarDelegate {
/// In this example, this method returns the section header title for the top visible section
func indicatorTitle(forOffset offset: CGFloat) -> String? {
return "Your title for info label"
}
}If you want to have iOS style scroll bar, configure ScrollBar with .iosStyle config (Next code will create config for the Scroll Bar for Gif #1):
scrollView.configureScrollBar(with: .iosStyle, delegate: self)Any ScrollBar configuration can be easily combined with another one (Next code will create config for the Scroll Bar for Gif #3):
let iosCombinedDefaultConfig = DMScrollBar.Configuration(
indicator: .init(
normalState: .iosStyle(width: 3),
activeState: .default
)
)
scrollView.configureScrollBar(with: iosCombinedDefaultConfig, delegate: self)If you want to configure scroll bar, with custom config, create configuration and call configureScrollBar (Next code will create config for the Scroll Bar for Gif #4):
let customConfig = DMScrollBar.Configuration(
isAlwaysVisible: false,
hideTimeInterval: 1.5,
shouldDecelerate: false,
indicator: DMScrollBar.Configuration.Indicator(
