Pod Version Pod Platform Pod License Carthage compatible CocoaPods compatible

SVProgressHUD
is a clean and easy-to-use HUD meant to display the progress of an ongoing task on iOS and tvOS.

SVProgressHUD

Demo

Try

SVProgressHUD
on Appetize.io.

Installation

From CocoaPods

CocoaPods 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:
pod 'SVProgressHUD'

If you want to use the latest features of

SVProgressHUD
use normal external source dependencies.
pod 'SVProgressHUD', :git => 'https://github.com/SVProgressHUD/SVProgressHUD.git'

This pulls from the

master
branch directly.

Second, install

SVProgressHUD
into your project:
pod install

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
:
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.

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 add the following line to your Podfile:
use_frameworks!

If you added

SVProgressHUD
manually, just add a bridging header 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):
[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:

+ (void)show;
+ (void)showWithStatus:(NSString*)string;

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

+ (void)showProgress:(CGFloat)progress;
+ (void)showProgress:(CGFloat)progress status:(NSString*)status;

Dismissing the HUD

The HUD can be dismissed using:

+ (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.
+ (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:
+ (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)setForegroundImageColor:(nullable UIColor*)color;           // default is the same as foregroundColor
+ (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
.
