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.
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.
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.
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
