# style

An optional dictionary containing additional style values that are not explicitly defined by the receiver.

## Declaration

```swift
var style: [AnyHashable : Any]? { get set }
```

## Discussion

Discussion This dictionary may in turn have a style key, forming a hierarchy of default values. In the case of hierarchical style dictionaries the shallowest value for a property is used. For example, the value for “style.someValue” takes precedence over “style.style.someValue”. If the style dictionary doesn’t define a value for an attribute, the cell’s defaultValue(forKey:) class method is called. The style dictionary is not consulted for the following keys: bounds, frame. The default value of this property is nil. warning: If the style dictionary or any of its ancestors are modified, the values of the cell’s properties are undefined until the style property is reset.
