ATMHud - Library for the creation of HUDs in iPhone applications

I once needed a HUD for one of my iPhone apps, but was unhappy with the currently available libraries on the internet. Therefore, I decided to create my own library. I've released it as a static library last year, but a lot of people wanted to see the source, so here it is.

Operation

Create, configure, then show it. See the Demo app for more detail.

// Keep a strong ivar reference to it (ie, "ATMHud *hud")
hud = [[ATMHud alloc] initWithDelegate:self];  
// or  hud = [ATMHud new]; using the block delegate

[hud setCaption:@"Caption and an activity indicator."];
[hud setActivity:YES];
[hud showInView:self.view];
...
[hud hide];
// when the delegate method tells you it's finished, you can nil the ivar out if you want
hud = nil;
// if you use the block delegate, you can release the hud there (see DemoViewController)

##**** Original Modifications, David Hoerl 2011-2014 ****

The reason I adopted this HUD is because it looks so nice, and it offered a wide range of customization options as well as the ability to get a slew of delegate messages as the HUD was presented and dismissed. Along with those you can get messages when the user taps within, or outside, the HUD.

I needed needed ARC, so I forked the project. My initial changes:

• ARCified
• Modern syntax, default setters (no @synthesize)
• more of the existing properties exposed along with some new ones
• blockDelegate along with or for use without the traditional 'delegate' callbacks
• sound can be compiled out of the framework if you aren't using it (assuming most do not.)
• converted to build error/warning free on iOS7 (required constant changes, many changes to UIKit extensions to NSString
• 64 bit clean
• handles view rotation (was a bug on original repository, unsure if I fixed it or not)

##Futures:

iOS7 circular determinate progress indicator (just ask for it!)

##History:

#4.0.0 - 2/15/2016

• Adopt more modern look - white with dark objects (text, progress indication, etc)
• Parallax added as a default
• Circular Progess Style Option
• Enums -> NS_ENUM for Swift
• Nullabilty for Swift

Note: if you used the older code and switch to this version, you may need to do some edits to your project.

#3.0.0 - 2/20/2014

• Added a Podspec to CocoaPods for this version
• Font now uses UIFont ' preferredFontForTextStyle:UIFontTextStyleSubheadline''
• Drop shadow removed (code still there, you can enable it if desired) for a more iOS7 look
• Modified appearance defaults to
  hud.appearScaleFactor = 0.8f;
  hud.disappearScaleFactor = 0.8f;
  hud.gray = 0.2f;
  hud.alpha = 0.8f;
• Rolled in some of the original issues posted to atomcraft/ATMHud
  14 - Gray property to set background color to a gray (not black), and added a setCenter method
  15 - Screenshots in Readme.md
  17 - Different orientation support? (assume this meant a landscape issue) 18 - use blocks api instead delegate 21 - Pull Request - Small performance update
  22 - Retain Cycle - changed property to "weak"
  23 - removeViewWhenHidden property added (use ATMHud without a delegate)
• Experiment with various UI option by changing properties in DemoViewController (see pragma)

#2.x.x - 2011 - 2013

• various small tweaks, mostly to address Xcode Analyze errors
• 64 bit clean

#2.0.0 - 2011

• Forked code
• ARCified

#1.2 - Original

The demo project shows of most of the ways you can display the HUD (but not all the UI customization options):

NOTE: The original author's text follows the screen shots.
