+
+`SVProgressHUD` is a clean and easy-to-use HUD meant to display the progress of an ongoing task on iOS and tvOS.
+
+![SVProgressHUD](http://f.cl.ly/items/2G1F1Z0M0k0h2U3V1p39/SVProgressHUD.gif)
+
+## Demo		
+
+Try `SVProgressHUD` on [Appetize.io](https://appetize.io/app/p8r2cvy8kq74x7q7tjqf5gyatr).
+
+## Installation
+
+### From CocoaPods
+
+[CocoaPods](http://cocoapods.org) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like `SVProgressHUD` in your projects. First, add the following line to your [Podfile](http://guides.cocoapods.org/using/using-cocoapods.html):
+
+```ruby
+pod 'SVProgressHUD'
+```
+
+If you want to use the latest features of `SVProgressHUD` use normal external source dependencies.
+
+```ruby
+pod 'SVProgressHUD', :git => 'https://github.com/SVProgressHUD/SVProgressHUD.git'
+```
+
+This pulls from the `master` branch directly.
+
+Second, install `SVProgressHUD` into your project:
+
+```ruby
+pod install
+```
+
+### Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate `SVProgressHUD` into your Xcode project using Carthage, specify it in your `Cartfile`:
+
+```ogdl
+github "SVProgressHUD/SVProgressHUD"
+```
+
+Run `carthage bootstrap` to build the framework in your repository's Carthage directory. You can then include it in your target's `carthage copy-frameworks` build phase. For more information on this, please see [Carthage's documentation](https://github.com/carthage/carthage#if-youre-building-for-ios-tvos-or-watchos).
+
+### Manually
+
+* Drag the `SVProgressHUD/SVProgressHUD` folder into your project.
+* Take care that `SVProgressHUD.bundle` is added to `Targets->Build Phases->Copy Bundle Resources`.
+* Add the **QuartzCore** framework to your project.
+
+## Swift
+
+Even though `SVProgressHUD` is written in Objective-C, it can be used in Swift with no hassle. If you use [CocoaPods](http://cocoapods.org) add the following line to your [Podfile](http://guides.cocoapods.org/using/using-cocoapods.html):
+
+```ruby
+use_frameworks!
+```
+
+If you added `SVProgressHUD` manually, just add a [bridging header](https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html) file to your project with the `SVProgressHUD` header included.
+
+## Usage
+
+(see sample Xcode project in `/Demo`)
+
+`SVProgressHUD` is created as a singleton (i.e. it doesn't need to be explicitly allocated and instantiated; you directly call `[SVProgressHUD method]`).
+
+**Use `SVProgressHUD` 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 `SVProgressHUD` in your app will usually look as simple as this (using Grand Central Dispatch):
+
+```objective-c
+[SVProgressHUD show];
+dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
+    // time-consuming task
+    dispatch_async(dispatch_get_main_queue(), ^{
+        [SVProgressHUD dismiss];
+    });
+});
+```
+
+### Showing the HUD
+
+You can show the status of indeterminate tasks using one of the following:
+
+```objective-c
++ (void)show;
++ (void)showWithStatus:(NSString*)string;
+```
+
+If you'd like the HUD to reflect the progress of a task, use one of these:
+
+```objective-c
++ (void)showProgress:(CGFloat)progress;
++ (void)showProgress:(CGFloat)progress status:(NSString*)status;
+```
+
+### Dismissing the HUD
+
+The HUD can be dismissed using:
+
+```objective-c
++ (void)dismiss;
++ (void)dismissWithDelay:(NSTimeInterval)delay;
+```
+
+If you'd like to stack HUDs, you can balance out every show call using:
+
+```
++ (void)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.
+
+```objective-c
++ (void)showInfoWithStatus:(NSString*)string;
++ (void)showSuccessWithStatus:(NSString*)string;
++ (void)showErrorWithStatus:(NSString*)string;
++ (void)showImage:(UIImage*)image status:(NSString*)string;
+```
+
+## Customization
+
+`SVProgressHUD` can be customized via the following methods:
+
+```objective-c
++ (void)setDefaultStyle:(SVProgressHUDStyle)style;                  // default is SVProgressHUDStyleLight
++ (void)setDefaultMaskType:(SVProgressHUDMaskType)maskType;         // default is SVProgressHUDMaskTypeNone
++ (void)setDefaultAnimationType:(SVProgressHUDAnimationType)type;   // default is SVProgressHUDAnimationTypeFlat
++ (void)setContainerView:(UIView*)containerView;                    // default is window level
++ (void)setMinimumSize:(CGSize)minimumSize;                         // default is CGSizeZero, can be used to avoid resizing
++ (void)setRingThickness:(CGFloat)width;                            // default is 2 pt
++ (void)setRingRadius:(CGFloat)radius;                              // default is 18 pt
++ (void)setRingNoTextRadius:(CGFloat)radius;                        // default is 24 pt
++ (void)setCornerRadius:(CGFloat)cornerRadius;                      // default is 14 pt
++ (void)setBorderColor:(nonnull UIColor*)color;                     // default is nil
++ (void)setBorderWidth:(CGFloat)width;                              // default is 0
++ (void)setFont:(UIFont*)font;                                      // default is [UIFont preferredFontForTextStyle:UIFontTextStyleSubheadline]
++ (void)setForegroundColor:(UIColor*)color;                         // default is [UIColor blackColor], only used for SVProgressHUDStyleCustom
++ (void)setBackgroundColor:(UIColor*)color;                         // default is [UIColor whiteColor], only used for SVProgressHUDStyleCustom
++ (void)setBackgroundLayerColor:(UIColor*)color;                    // default is [UIColor colorWithWhite:0 alpha:0.4], only used for SVProgressHUDMaskTypeCustom
++ (void)setImageViewSize:(CGSize)size;                              // default is 28x28 pt
++ (void)setShouldTintImages:(BOOL)shouldTintImages;                 // default is YES
++ (void)setInfoImage:(UIImage*)image;                               // default is the bundled info image provided by Freepik
++ (void)setSuccessImage:(UIImage*)image;                            // default is bundled success image from Freepik
++ (void)setErrorImage:(UIImage*)image;                              // default is bundled error image from Freepik
++ (void)setViewForExtension:(UIView*)view;                          // default is nil, only used if #define SV_APP_EXTENSIONS is set
++ (void)setGraceTimeInterval:(NSTimeInterval)interval;              // default is 0 seconds
++ (void)setMinimumDismissTimeInterval:(NSTimeInterval)interval;     // default is 5.0 seconds
++ (void)setMaximumDismissTimeInterval:(NSTimeInterval)interval;     // default is CGFLOAT_MAX
++ (void)setFadeInAnimationDuration:(NSTimeInterval)duration;        // default is 0.15 seconds
++ (void)setFadeOutAnimationDuration:(NSTimeInterval)duration;       // default is 0.15 seconds
++ (void)setMaxSupportedWindowLevel:(UIWindowLevel)windowLevel;      // default is UIWindowLevelNormal
++ (void)setHapticsEnabled:(BOOL)hapticsEnabled;                     // default is NO
+```
+
+Additionally `SVProgressHUD` supports the `UIAppearance` protocol for most of the above methods.
+
+### Hint
+
+As standard `SVProgressHUD` offers two preconfigured styles:
+
+* `SVProgressHUDStyleLight`: White background with black spinner and text
+* `SVProgressHUDStyleDark`: 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 `SVProgressHUDStyleCustom`.
+
+## Haptic Feedback
+
+For users with newer devices (starting with the iPhone 7), `SVProgressHUD` 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
+
+`SVProgressHUD` posts four notifications via `NSNotificationCenter` in response to being shown/dismissed:
+* `SVProgressHUDWillAppearNotification` when the show animation starts
+* `SVProgressHUDDidAppearNotification` when the show animation completes
+* `SVProgressHUDWillDisappearNotification` when the dismiss animation starts
+* `SVProgressHUDDidDisappearNotification` when the dismiss animation completes
+
+Each notification passes a `userInfo` dictionary holding the HUD's status string (if any), retrievable via `SVProgressHUDStatusUserInfoKey`.
+
+`SVProgressHUD` also posts `SVProgressHUDDidReceiveTouchEventNotification` when users touch on the overall screen or `SVProgressHUDDidTouchDownInsideNotification` 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 `SVProgressHUD` in an App Extension, `#define SV_APP_EXTENSIONS` to avoid using unavailable APIs. Additionally call `setViewForExtension:` from your extensions view controller with `self.view`.
