iOS loading indicator

So I have decided to create another iOS loading indicator instead of the default iOS activity indicator, that is pretty useless and boring for a normal app. So I have wrote my ARSLineProgress iOS progress HUD. You can check out the source code and the ways to get it for your project here on my GitHub repository: ARSLineProgress.

Infinite Success Fail
ARSLineProgress Infinite ARSLineProgress Success ARSLineProgress Fail

Usage

ARSLineProgress makes it easy to use it - you have ARSLineProgress class, that offers you a wide range of class methods to show progress loader.

Showing

You can show progress indicator in two modes: infinite and progress. Infinite one will be shown until you hide it.

class func show()
class func showWithPresentCompetionBlock(block: () -> Void)
class func showOnView(view: UIView)
class func showOnView(view: UIView, completionBlock: () -> Void)

class func hide()
class func hideWithCompletionBlock(block: () -> Void)

Progress indicator will be shown until the NSProgress object has the fractionCompleted value 1.0 or in case you have passed raw value - 100.0.

class func showWithProgressObject(progress: NSProgress)
class func showWithProgressObject(progress: NSProgress, completionBlock: (() -> Void)?)
class func showWithProgressObject(progress: NSProgress, onView: UIView)
class func showWithProgressObject(progress: NSProgress, onView: UIView, completionBlock: (() -> Void)?)

// Updating progress in case you are using on of the methods above:
class func updateWithProgress(value: CGFloat)

// initialValue should be from 0 to 100 in these methods
class func showWithProgress(initialValue value: CGFloat)
class func showWithProgress(initialValue value: CGFloat, completionBlock: (() -> Void)?)
class func showWithProgress(initialValue value: CGFloat, onView: UIView)
class func showWithProgress(initialValue value: CGFloat, onView: UIView, completionBlock: (() -> Void)?)

You are able to show just the 'success' checkmark or fail with these methods:

static func showSuccess()
static func showFail()

Hiding

Hiding progressHUD can be similar to what you have done so far with the infinite loader, or you could use these dedicated methods:

class func cancelPorgressWithFailAnimation(showFail: Bool)
class func cancelPorgressWithFailAnimation(showFail: Bool, completionBlock: (() -> Void)?)

Customization

You can customize progressHUD through the ARSLineProgressConfiguration structure, that offers you a wide range of customization. Any changes are going to be visible only if you have set them before showing preloader, otherwise they are going to be visible during your next show of preloader.

Once you have changed your mind and you want to restore ARSLineProgressConfiguration to its default parameters - use static func restoreDefaults() method.
