29/02 IMPORTANT CHANGE: SVProgressHUD no longer interacts with iOS’s status bar network activity indicator. Dedicated methods have been deprecated and you will need to show/hide the activity indicator yourself (ideally from a controller or the class that makes the network requests).

SVProgressHUD

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)
};

Automatic Reference Counting (ARC) support

Maintaining an official ARC branch has proven to be too much work, often leading to confusion since the ARC branch is always a few commits behind. If you’d like to use SVProgressHUD in your ARC-enabled project, you’ll have to add the -fno-objc-arc compiler flag to all of SVProgressHUD’s files.
