How to set default values for IBInspectable in Objective-C?

Question

I know default values of IBInspectable-properties can be set as:

@IBInspectable var propertyName:propertyType = defaultValue in Swift. But how do I achieve

Answer 1

Why don't use use the macro such as:

#if TARGET_INTERFACE_BUILDER   
// .....IB only specific code when being rendered in IB 
#endif 

???

The prepareForInterfaceBuilder selector may also help you to implement IB specific code.
