初始化的3种方法
//重写的init方法
//使用遍历初始化函数初始化
//使用构造遍历器初始化

mian.h#import <Foundation/Foundation.h>#import "Student.h"int main(int argc, const char * argv[]) {    @autoreleasepool {        //重写的init方法        Student *stu3 = [[Student alloc] init];        [stu3 sayHi];        //使用遍历初始化函数  初始化        Student *stu  = [[Student alloc] initWithName:@"张三" andAge:18 andHobby:@"玩游戏" andAddr:@"月球"];        [stu sayHi];        //使用构造遍历器 初始化        Student *stu1 = [Student studentWithName:@"lisi" andAge:18 andHobby:@"23" andAddr:@"dd"];        [stu1 sayHi];    }    return 0;}Student.h#import <Foundation/Foundation.h>@interface Student : NSObject{    NSString * _name;    int _age;    NSString * _hobby;    NSString * _addr;}#pragma mark 遍历构造器/** 遍历构造器 */+(Student *)studentWithName:(NSString *)name andAge:(int)age andHobby:(NSString *)hobby andAddr:(NSString *)addr;#pragma mark 遍历出使唤函数/** 遍历初始化函数 */-(Student *)initWithName:(NSString *)name andAge:(int)age andHobby:(NSString *)hobby andAddr:(NSString *)addr;#pragma mark 功能函数-(void)sayHi;@endStudent.m#import "Student.h"@implementation Student/** 重写的init的方法 */-(instancetype)init{    if (self = [super init]) {        _name = @"莉丝";    }    return self;}-(Student *)initWithName:(NSString *)name andAge:(int)age andHobby:(NSString *)hobby andAddr:(NSString *)addr{    if (self=[super init]) {        _name = name;        _age = age;        _hobby = hobby;        _addr = addr;    }    return self;}+(Student *)studentWithName:(NSString *)name andAge:(int)age andHobby:(NSString *)hobby andAddr:(NSString *)addr{    Student *stu = [[Student alloc] initWithName:name andAge:age andHobby:hobby andAddr:addr];    return stu;}-(void)sayHi{    NSLog(@"%@向你说hello",_name);}@end
