Question about init in classes

[G.B.Yahav]

Hey,
I've learned classes in Objective-C but lately i've found something "weird" or I just didn't saw any example of people who done it:
I've created a new class, for example

@interface Car : NSObject {
    NSString *carOwner;
    NSString *carColor;
}

-(Car *) initWithCarOwner: (NSString *) owner andColor: (NSString *) color;
@end

When Im implementing the initwithcarownerandcolor I am allocating the memory for those two variables (somthing like):

{
    carOwner = [[NSString alloc] initWithString: owner];
    carColor = [[NSString alloc] initWithString: color];
}

But what if the user wont initialize the object from this method, and instead will do:

Car *c = [[Car alloc] init];

Those variables wont be initialized (Or they are?) so.. what I need to do? maybe I need to implement the init method? (I just don't know because I'm reading an Objective-C book but I never saw an example with init override...)

Looking forward your help, thanks!

You need to override the init method like you thought.

Ok, good to hear.
