initialize方法主要用来对一些不方便在编译期初始化的对象进行赋值。比如NSMutableArray这种类型的实例化依赖于runtime的消息发送,所以显然无法在编译器初始化: //In Parent.mstaticintsomeNumber =0;//int类型可以在编译期赋值staticNSMutableArray *someObjects;+ (void)initialize {if(self == [Parentclass]) {/...
Because our array contains only null values at the initialization, we use the method fill() to populate it with our desired value, 0, in our case. This method works like nCopies(), populating our array with the value given as a parameter. After filling the array with zeros, we can ...
