Using MCObservation

Observing changes to models

Make your view objects observe your models for changes:

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
  self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
      [self mc_observeKeyPath:@"object.title" withBlock: ^(NSString *keyPath, NSDictionary *change) {
      self.textLabel.text = self.object.title;
    }];
  }
  return self;
}

Keyboard Animations

You can configure velocity, springBounciness and springSpeed.

[self mc_animateAlongsideKeyboardWithShowAnimations: ^(CGRect keyboardFrame) {
    self.textField.backgroundColor = [UIColor colorWithRed:1.000 green:0.231 blue:0.188 alpha:0.5];
} andHideAnimations: ^(CGRect keyboardFrame) {
    self.textField.backgroundColor = nil;
}];

There is no need to unregister any notifications.
