1.

Strong for general objects

Weak for UI Objects

Assign for structural type

%02d integers save 2 bits, not enough of the front fill 0

Duplicate Code encapsulation extraction, the duplication of things extracted to write to the function, the different things as parameters

/**

2.

Delayed loading of data (lazy loading) (the way in which attributes are initialized in the get method), loaded with time, adding a get method

-(nsarray *) array

{

if (_array = = nil)// is never initialized

{

Initialize data }

Return _array

}

If the first load is _array , the Get method is not called , and the resulting array is empty,

Self.array is required for deferred load calls
