RNAvatarLogin

This project was entirely inspired by the beautiful GoSquared Login. It is a really unique and peculiar way to "entertain" the user while a task completes. Using a Gravatar fulfills purposes in a login: it lets the user validate that they have entered their email, and it also provides a more personal experience by welcoming the user to see their account.

Installation

Super simple. Just drag & drop both RNAvatarLogin .h and .m files into your project.

In your Build Phases > Link Binary With Libraries add the Quartzcore.framework to your project.

Usage

The simplest way to get started is to create a UIImageView and UITextField in a NIB or Storyboard and then set their classes to RNAvatarImageView and RNEmailField, respectively. Then add the following to your view controller:

self.emailField.avatarImageView = self.avatarImageView;

That will run with the default settings and swap images as soon as a Gravatar is found.

Config

I've tried my best to provide some simple configuration settings to aid in animation and appearance of the Gravatar. Here are all of the available configuration settings.

@interface RNAvatarImageView

// animation
@property (assign) BOOL avatarHasFadeAnimation;     // default YES
@property (assign) CGFloat avatarFadeDuration;      // default 0.3 seconds

// appearance
@property (assign) CGFloat avatarCornerRadius;
@property (assign) CGFloat avatarBorderWidth;
@property (strong) UIColor *avatarBorderColor;
@property (assign) CGSize avatarShadowOffset;
@property (assign) CGPathRef avatarShadowPath;
@property (strong) UIColor *avatarShadowColor;
@property (assign) CGFloat avatarShadowOpacity;
@property (assign) CGFloat avatarShadowRadius;

@end

@interface RNEmailField : UITextField

// how many characters until requests start firing
@property (assign) NSInteger minCharactersForRequest;   // default 10 chars

@end
