Question

First day learning Objective-C but have a java background. I’d like to use the same variable name for my parameter that I do for my instance variable. In java we do it like this

public class Person
{
    private String name;
    private String age;

    public void setName(String name)
    {
        this.name = name;
    }
    public void setAge(String age)
    {
        this.age = age;
    }
}

In objective c so far I have this

@interface Person : NSObject
{
    int age;
    int name;
}
    -(void) setAge:(int) age;
    -(void) setName:(int) name;
    -(int) getAge;
    -(int) getName;
@end

@implementation Person
-(void) setName:(int) w
{
    weight = w;
}
-(void) setAge:(int) a
{
    age = a;
}
-(int) getName
{
    return name;
}
-(int) getAge
{
    return age;
}
@end

In Objective-C, you can define your own accessors or use @syntehsize to create them automatically for you.

In the case where you want to define accessors manually, setters are declared like this:

- (void)setName:(NSString *)name {

    self.name = name;
}

- (void)setAge:(NSInteger)age {

    self.age = age;
}

For getters, you simply declare them as follows:

- (NSString *)name {

    return self.name;
}

- (NSInteger)age {

    return self.age;
}
