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 by Lauren Britcher's HUD in Tweetie for iOS. The success and error icons are from Glyphish.

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
• Talks with setNetworkActivityIndicatorVisible (default can be changed via SVProgressHUDShowNetworkIndicator constant)
• 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 folder)

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

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)
};

Network activity indicator

By default, showing SVProgressHUD also activates the network activity indicator (this makes sense for apps that make a lot of network operations). If you'd like SVProgressHUD to not show the network indicator by default, you can add -DSVPROGRESSHUD_DISABLE_NETWORK_INDICATOR to your project's CFLAGS (in build settings). You can also set this on a per-call basis, using the show methods that boast a networkIndicator parameter.

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.
