KRIndicatorController is a controller for displaying background activity UI.
Installation
KRIndicatorController is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'KRIndicatorController', :git=>'https://github.com/funct7/KRIndicatorController.git', :branch=>'develop'Then, run the following command:
$ pod installUsage
Basic
Using the default indicator view:
import KRIndicatorController
class ViewController: UIViewController {
private let ic = IndicatorController()
private func beginOperation() {
ic.increment()
// Begin some operation
}
private func endOperation() {
// End some operation
ic.decrement()
}
}Custom indicator view
Using a custom indicator view:
import KRIndicatorController
class CustomIndicator: IndicatorItem {
var view: UIView
init() {
// Initialize
}
func animateShow() {
// Custom animation
}
func animateHide() {
// Custom animation
}
}
class ViewController: UIViewController {
private let ic = IndicatorController()
private func setCustomIndicatorView() {
ic.indicatorItem = CustomIndicator()
}
}Custom delay
Setting a custom delay value:
import KRIndicatorController
class ViewController: UIViewController {
private let ic = IndicatorController()
private func setCustomDelay() {
ic.delay = 0.3 // 300 ms delay
}
}Block/allow user interaction
Blocking the user interaction during indicator display:
import KRIndicatorController
class ViewController: UIViewController {
private let ic = IndicatorController()
override func viewDidLoad() {
super.viewDidLoad()
ic.isUserInteractionBlocked = true // Default is true
}
}Setting isUserInteractionBlocked to false allows users to interact with the underlying view.
