Three types of initialization

In the parent class-(ID) initwithname :( nsstring *) aname
Sex :( nsstring *) asex
Age :( nsinteger) Aage
{
// Call the initialization method of the parent class
Self = [Super init]; // prevents initialization failure and assignment failure
If (Self ){
// Assign values to your instance variables
_ Name = aname;
_ Sex = asex;
_ Age = Aage;
}
Return self;
}
In the subclass (specified)-(ID) initwithname :( nsstring *) aname
Score :( float) ASCORE
Sex :( nsstring *) asex
Age :( nsinteger) Aage
Number :( nsstring *) anumber
{
// Super has only one function. It calls the parent class method.
// Call the parent class method and assign values to the instance variables of the parent class
Self = [Super initwithname: aname sex: asex age: Aage];
If (Self ){
// Assign values to your instance variables
_ Number = anumber;
_ Score = ASCORE;
}
Return self;
}
Other initialization methods (general)-(ID) initwithname :( nsstring *) aname
Score :( float) ASCORE
Number :( nsstring *) anumber
{
Return [self initwithname: aname score: ASCORE sex: nilage: 0 Number: anumber];
}
