oc对象初始化

一、对象初始化
Person.h

#import<Foudation/Foudation.h>

@interface:NSObject
{
    NSString *_name;
    NSInteger _age;

}
-(id)initWithName:(NNString *)name withAge: Integer age;
-(void)showInfo;
@end

Person.m

#import "Person.h"
@implementation Person
-(id)initWithNmae:(NNString *)name withAge:(NSInteger)age{
    if(self =[super init])
    {
    _name=name;
    _age=age;
    }
    return self;
-(void)test
{
                NSLog(@"test");

}
-(void)showInfo
{
NSLog(@"name is %s and age is %d",_name,_age)
}
    }

main.m

#import <Foudation/Foudation.h>
#import "Person.h"

int main(int argc,const charchar *argv[]){
@autoreleasepol{
Person *person=[[Person alloc]init];
[person initWithName:@"zhangshan" withAge:22];
[person showInfo];

}

return 0;
}
