Custom Enumerated Property definition

[tbrannam]

While it is easy to support custom string properties by way of registerCustomProperty, it seems less clear how to support custom properties with enumerated types - as the implementation to create these is private and the the returned ISSPropertyDefinition consists of readonly fields. should these be promoted to a public interface? Should registerCustomProperty have a implementation that accepts a ISSPropertyDescription?

// Private initializer
- (id) initWithName:(NSString *)name aliases:(NSArray*)aliases type:(ISSPropertyType)type enumBlock:(NSDictionary*)enumValues enumBitMaskType:(BOOL)enumBitMaskType;

By importing the private category

#import <InterfaCSS/ISSPropertyDefinition+Private.h> 

and adding to ISSPropertyRegistery

- (void) registerCustomPropertyDefinition:(ISSPropertyDefinition *)propertyDefinition {
      if (propertyDefinition)
          self.propertyDefinitions = [self.propertyDefinitions setByAddingObject:propertyDefinition];
}

I was able to add an enumerated type to support a custom view

ISSPropertyDefinition *imageViewContentMode =
        [[ISSPropertyDefinition alloc] initWithName:@"imageAlign"
                                          aliases:nil
                                         type:ISSPropertyTypeEnumType
                                   enumValues:@{ @"center" : @(UIImageViewAlignmentMaskCenter),
                                                 @"left" : @(UIImageViewAlignmentMaskLeft),
                                                 @"right" : @(UIImageViewAlignmentMaskRight),
                                                 @"top" : @(UIImageViewAlignmentMaskTop),
                                                 @"bottom" : @(UIImageViewAlignmentMaskBottom)}
                                enumBitMaskType:YES
                                    setterBlock:^(ISSPropertyDefinition* property, id viewObject, id value, NSArray* parameters) {
                                                     if( [viewObject isKindOfClass:UIImageViewAligned.class] ) {
                                                         UIImageViewAligned* v = viewObject;
                                                         v.alignment = (UIImageViewAlignmentMask)[value unsignedIntegerValue];
                                                     }
                                                 } parameterEnumValues:nil];

[[[InterfaCSS interfaCSS] propertyRegistry] registerCustomPropertyDefinition:imageViewContentMode];

Fixed in 0162ed5 - exposed full interface of ISSPropertyDefinition in ISSPropertyDefinition.h and added method to register a property definition directly to ISSPropertyRegistery.
