If your project doesn't use ARC: you must add the -fobjc-arc compiler flag to SVProgressHUD.m in Target Settings > Build Phases > Compile Sources.

SVProgressHUD

SVProgressHUD is a clean and easy-to-use HUD meant to display the progress of an ongoing task.

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]).

Showing the HUD

You can show the status of indeterminate tasks using:

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

If you'd like the HUD to reflect the progress of a task, use:

+ (void)showProgress:(CGFloat)progress;
+ (void)showProgress:(CGFloat)progress status:(NSString*)status;
+ (void)showProgress:(CGFloat)progress status:(NSString*)status maskType:(SVProgressHUDMaskType)maskType;

SVProgressHUDMaskType

You can optionally disable user interactions while the HUD is shown 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)
};

Dismissing the HUD

It can be dismissed right away using:

+ (void)dismiss;

Or show a confirmation glyph before before getting dismissed 1 second later using:

+ (void)showSuccessWithStatus:(NSString*)string;
+ (void)showErrorWithStatus:(NSString *)string;
+ (void)showImage:(UIImage*)image status:(NSString*)string; // use 28x28 white pngs
