SVProgressHUD

SVProgressHUD is a clean, lightweight and unobtrusive 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
optional loading, success and error status messages
automatic positioning based on device type, orientation, keyboard visibility and optional posY parameter
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)

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;

If you need to add the HUD to a particular view, use one of the following:

+ (void)showInView:(UIView*)view;
+ (void)showInView:(UIView*)view status:(NSString*)string;
+ (void)showInView:(UIView*)view status:(NSString*)string networkIndicator:(BOOL)show;
+ (void)showInView:(UIView*)view status:(NSString*)string networkIndicator:(BOOL)show posY:(CGFloat)posY;
+ (void)showInView:(UIView*)view status:(NSString*)string networkIndicator:(BOOL)show posY:(CGFloat)posY maskType:(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)
};

Network activity indicator

By default, showing SVProgressHUD will also show the network activity indicator (this makes sense for apps that make a lot of network operations). You can change this behavior by setting the SVProgressHUDShowNetworkIndicator constant to 0 in SVProgressHUD.h.
