SVProgressHUD

Swift Package

Swift Package 📦 SVProgressHUD is a clean and easy-to-use HUD meant to display the progress of an ongoing task on iOS and tvOS. Refactored Swift Package Manager version of the SVProgressHUD.

Installation

Use Swift Package Manager to install.

Usage

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.

Flawless stacking

If you'd like to stack the same HUD on top of the previous one, as in case of serial requests to the remote presenting new HUD at the start of each one, stacking will produce a blinking effect. To achieve a flawless stacking without the HUD interface blinking use:

+ (void)setFlawlessStackingEnabled:(BOOL)isFlawlessStackingEnabled;

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)setHudViewCustomBlurEffect:(nullable UIBlurEffect*)blurEffect;  // default is nil, only used for SVProgressHUDStyleCustom, can be combined with backgroundColor
+ (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)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 infinite
+ (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)setFlawlessStackingEnabled:(BOOL)isFlawlessStackingEnabled;     // default is NO
+ (void)setHapticsEnabled:(BOOL)hapticsEnabled;                         // default is NO
+ (void)setMotionEffectEnabled:(BOOL)motionEffectEnabled;               // default is YES

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.
