Objective-c Initialization method

1. Initialization method:

#import <Foundation/Foundation.h>

@interface person:nsobject{

NSString *_name;

Nsinteger _age;

}

Custom initialization method, must start with Init

-(ID) initwithname: (nsstring *) name withage: (Nsinteger) age;

Printing information

-(void) showinfo;

@end

Here we define an initialization method that initializes the name and age of the assignment operation

Method implementation:

#import "Person.h"

@implementation person

-(ID) initwithname: (nsstring *) name withage: (nsinteger) age{

Fixed writing, you can back down Oh ~ ~

Calling the initialization method of the parent class

self = [super Init];

if (self!= nil) {

_name = name;

_age = age;

}

return self ;

}

@end

Note: The name of the custom initialization method in OC must start with Init
