Can I assume declared but uninitialized variable to have the value of nil (for pointer type) or 0 (for numeric type)?

The objective-c runtime ensures that member variables will be initialized to zero when memory for an object is allocated. It makes no other assurances (local variables aren't zeroed, etc.).
