| // ---------QUESTIONS--------- | |
| // 1. Should you do this, only to avoid casting later when you need to access MyCustomView specific properties? | |
| // 2. How does the compiler treat this property (and the backing ivar) that's re-declared at the inheriting class level? | |
| // Does it shadow the version that exists at the UIViewController level? | |
| // 3. Wouldn't this cause a leak? | |
