Note: SVProgressHUD now uses Automatic Reference Counting (ARC). Find the last MRC commit on the last-mrc branch.

SVProgressHUD is an easy-to-use, clean and lightweight progress HUD for iOS. It’s a simplified and prettified alternative to the popular MBProgressHUD. Its fade in/out animations are highly inspired on Lauren Britcher’s HUD in Tweetie for iOS. The success and error icons are from Glyphish.

SVProgressHUD features:

• very simple singleton convenience methods ([SVProgressHUD show], [SVProgressHUD dismiss], etc.)
• optional loading, success and error status messages
• automatic positioning based on device type, orientation and keyboard visibility
• optionally disable user interactions while the HUD is showing with the maskType parameter

Installation

• Drag the SVProgressHUD/SVProgressHUD folder into your project.
• Add the QuartzCore framework to your project.

If you plan on using SVProgressHUD in a lot of places inside your app, I recommend importing it directly inside your prefix file.

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]) and can be shown using one of the following convenience/class methods:

+ (void)show;
+ (void)showWithStatus:(NSString*)status;
+ (void)showWithStatus:(NSString*)status maskType:(SVProgressHUDMaskType)maskType;
+ (void)showWithMaskType:(SVProgressHUDMaskType)maskType;

You dismiss it using one of these:

+ (void)dismiss;
+ (void)dismissWithSuccess:(NSString*)successString;
+ (void)dismissWithSuccess:(NSString*)successString afterDelay:(NSTimeInterval)seconds;
+ (void)dismissWithError:(NSString*)errorString;
+ (void)dismissWithError:(NSString*)errorString afterDelay:(NSTimeInterval)seconds;

If you’re using SVProgressHUD to show the status of a many-steps operation, you can also change the HUD status while it’s showing with:

+ (void)setStatus:(NSString*)string;

Additionally, you can use SVProgressHUD to display a simple confirmation/success HUD using:

+ (void)showSuccessWithStatus:(NSString*)string;

SVProgressHUDMaskType

You can optionally disable user interactions and dim the background UI using the maskType property:

enum {
    SVProgressHUDMaskTypeNone = 1, // allow user interactions, don't dim background UI (default)
    SVProgressHUDMaskTypeClear, // disable user interactions, don't dim background UI
    SVProgressHUDMaskTypeBlack, // disable user interactions, dim background UI with 50% translucent black
    SVProgressHUDMaskTypeGradient // disable user interactions, dim background UI with translucent radial gradient (a-la-alertView)
};
