# IHProgressHUD



`IHProgressHUD` is a clean and easy-to-use HUD meant to display the progress of an ongoing task on iOS and tvOS. `IHProgressHUD` is based on [SVProgressHUD](https://github.com/SVProgressHUD/SVProgressHUD) and ported to Swift with the [help of Swiftify](https://medium.com/swiftify/converting-svprogresshud-to-swift-using-swiftify-27be1817b7f6),

with improvements like added thread safety and not using complier flag for use in iOS App Extension. 



If you are interested in learning more about the conversion process, please [checkout](https://medium.com/swiftify/converting-svprogresshud-to-swift-using-swiftify-27be1817b7f6).

## Demo        



Try `IHProgressHUD` on [Appetize.io](https://appetize.io/app/hn358rg7zc8uyethqayub23h2c).



## Installation



### From CocoaPods



[CocoaPods](http://cocoapods.org) is a dependency manager for Objective-C and Swift, which automates and simplifies the process of using 3rd-party libraries like `IHProgressHUD` in your projects. First, add the following line to your [Podfile](http://guides.cocoapods.org/using/using-cocoapods.html):



```ruby

pod 'IHProgressHUD'

```



If you want to use the latest features of `IHProgressHUD` use normal external source dependencies.



```ruby

pod 'IHProgressHUD', :git => 'https://github.com/Swiftify-Corp/IHProgressHUD.git'

```



This pulls from the `master` branch directly.



Second, install `IHProgressHUD` into your project:



```ruby

pod install

```



### From SwiftPM



Under your project from the `File` menu, go to `Swift Packages` and select `Add Package Dependency`



Enter the address of the repository for the package you wish to add.

- https://github.com/Swiftify-Corp/IHProgressHUD.git



After you hit `Next`, you’ll see another form. From here you’re able to specify which `version`, `branch`, or `commit hash` you’d like to add as a dependency.



After you click `Next`, Xcode will fetch the dependency. In this final window, make sure the package you want to add is checked and the target you wish to add it to is selected from the dropdown.



After you click Finish, you’ll see that the added package is now listed in the navigator under a new section titled `Swift Package Dependencies`.



#### To Remove the package



If you need to remove a SwiftPM package from your project, you can select the project at the top of the navigator, then look for the tab titled `Swift Packages`. (It’s next to `Build Settings`). 



## Usage



`IHProgressHUD` is created as a singleton (i.e. it doesn't need to be explicitly allocated and instantiated; you directly call `IHProgressHUD.method()`). It can be accessed from even the background thread.



**Use `IHProgressHUD` wisely! Only use it if you absolutely need to perform a task before taking the user forward. Bad use case examples: pull to refresh, infinite scrolling, sending message.**



Using `IHProgressHUD` in your app will usually look as simple as this (using Grand Central Dispatch):



```Swift

IHProgressHUD.show()

DispatchQueue.global(qos: .default).async(execute: {

// time-consuming task

IHProgressHUD.dismiss()

})

```



### Showing the HUD



You can show the status of indeterminate tasks using one of the following:



```Swift

class func show()

class func show(withStatus status: String?)

```



If you'd like the HUD to reflect the progress of a task, use one of these:



```Swift

class func show(progress: CGFloat)

class func show(progress: CGFloat, status: String?)

```



### Dismissing the HUD



The HUD can be dismissed using:



```Swift

class func dismiss()

class func dismissWithCompletion(_ completion: (() -> Void)?)

class func dismissWithDelay(_ delay: TimeInterval)

class func dismissWithDelay(_ delay: TimeInterval, completion: (() -> Void)?)

```



If you'd like to stack HUDs, you can balance out every show call using:



```

class func popActivity()

```



The HUD will get dismissed once the popActivity calls will match the number of show calls.



Or show a confirmation glyph before before getting dismissed a little bit later. The display time depends on `minimumDismissTimeInterval` and the length of the given string.



```Swift

class func showInfowithStatus(_ status: String?)

class func showSuccesswithStatus(_ status: String?)

class func showError(withStatus status: String?)

class func showImage(_ image: UIImage, status: String?)

```



## Customization



`IHProgressHUD` can be customized via the following methods:



```Swift

class func set(defaultStyle style: IHProgressHUDStyle) // default is IHProgressHUDStyle.light



class func set(defaultMaskType maskType: IHProgressHUDMaskType) // default is IHProgressHUDMaskType.none



class func set(defaultAnimationType type: IHProgressHUDAnimationType) // default is IHProgressHUDAnimationType.flat



class func set(containerView: UIView?) // default is window level



class func set(minimumSize: CGSize) // default is CGSize.zero, can be used to avoid resizing



class func set(ringThickness: CGFloat) // default is 2 pt



class func set(ringRadius : CGFloat) // default is 18 pt



class func setRing(noTextRingRadius radius: CGFloat) // default is 24 pt



class func set(cornerRadius: CGFloat) // default is 14 pt



class func set(borderColor color : UIColor) // default is nil



class func set(borderWidth width: CGFloat)  // default is 0



class func set(font: UIFont) // default is UIFont.preferredFont(forTextStyle: .subheadline)



class func set(foregroundColor color: UIColor) // default is nil



class func set(backgroundColor color: UIColor) // default is nil



class func set(backgroundLayerColor color: UIColor) // default is UIColor(white: 0, alpha: 0.4), only used for IHProgressHUDMaskType.custom



class func set(imageViewSize size: CGSize) // default is 28x28 pt



class func set(shouldTintImages: Bool) // default is true



class func set(infoImage image: UIImage) // default is the bundled info image provided by Freepik



class func setSuccessImage(successImage image: UIImage) // default is bundled success image from Freepik



class func setErrorImage(errorImage image: UIImage) // default is bundled error image from Freepik



class func set(viewForExtension view: UIView) // default is nil, only used for App Extension



class func set(graceTimeInterval interval: TimeInterval) // default is 5.0 seconds



class func set(maximumDismissTimeInterval interval: TimeInterval) // default is TimeInterval(CGFloat.infinity)



class func setFadeInAnimationDuration(fadeInAnimationDuration duration: TimeInterval) // default is 0.15 seconds



class func setFadeOutAnimationDuration(fadeOutAnimationDuration duration: TimeInterval) // default is 0.15 seconds



class func setMaxSupportedWindowLevel(maxSupportedWindowLevel windowLevel: UIWindow.Level) // default is UIWindowLevelNormal



class func setHapticsEnabled(hapticsEnabled: Bool) // default is NO

```



### Hint



As standard `IHProgressHUD` offers two preconfigured styles:



* `IHProgressHUDStyle.light`: White background with black spinner and text

* `IHProgressHUDStyle.dark`: Black background with white spinner and text



If you want to use custom colors use `setForegroundColor` and `setBackgroundColor:`. These implicitly set the HUD's style to `IHProgressHUDStyle.custom`.



## Haptic Feedback



For users with newer devices (starting with the iPhone 7), `IHProgressHUD` can automatically trigger haptic feedback depending on which HUD is being displayed. The feedback maps as follows:



* `showSuccessWithStatus:` <-> `UINotificationFeedbackTypeSuccess`

* `showInfoWithStatus:` <-> `UINotificationFeedbackTypeWarning`

* `showErrorWithStatus:` <-> `UINotificationFeedbackTypeError`



To enable this functionality, use `setHapticsEnabled:`.



Users with devices prior to iPhone 7 will have no change in functionality.



## Notifications



`IHProgressHUD` posts four notifications via `NSNotificationCenter` in response to being shown/dismissed:

* `NotificationName.IHProgressHUDWillAppear` when the show animation starts

* `NotificationName.IHProgressHUDDidAppear` when the show animation completes

* `NotificationName.IHProgressHUDDidDisappear` when the dismiss animation starts

* `NotificationName.IHProgressHUDDidAppear` when the dismiss animation completes



Each notification passes a `userInfo` dictionary holding the HUD's status string (if any), retrievable via `[NotificationName.IHProgressHUDStatusUserInfoKey.getNotificationName()]`.



`IHProgressHUD` also posts `IHProgressHUDDidReceiveTouchEvent` when users touch on the overall screen or `IHProgressHUDDidTouchDownInside` when a user touches on the HUD directly. For this notifications `userInfo` is not passed but the object parameter contains the `UIEvent` that related to the touch.



## App Extensions



When using `IHProgressHUD` in an App Extension,  use the `class func set(viewForExtension view: UIView)` there is no need to set any complier flag.
