gruml / SVProgressHUD

A clean and lightweight progress HUD for your iOS app.

Important note 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 is an easy-to-use, clean and lightweight progress HUD for iOS. It’s a simplified and prettified alternative to the popular MBProgressHUD. The success and error icons are from Glyphish.

SVProgressHUD features:

• very simple singleton convenience methods ([SVProgressHUD show], [SVProgressHUD dismiss], etc.)
• display of status strings and/or images to quickly communicate the state of the ongoing task
• automatic positioning based on device type, orientation and keyboard visibility
• optionally disable user interactions for ongoing tasks using a 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)showWithMaskType:(SVProgressHUDMaskType)maskType;
+ (void)showWithStatus:(NSString*)string;
+ (void)showWithStatus:(NSString*)string maskType:(SVProgressHUDMaskType)maskType;

It can be dismissed using:

+ (void)dismiss;

Optionally, you can have the HUD display a status and/or an image glyph before automatically getting dismissed 1s later (not customizable anymore to discourage lenghty status strings — for which UIAlertViews would be more appropriate).

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

SVProgressHUDMaskType

You can optionally disable user interactions while a task is being completed by using the show methods that support 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)
};
