How to create Custom delegate method in iOS

Delegate is used for send receive data between two viewcontroller.

For example if We have two View controllers namely FirstViewController and

SecondViewController

Step :1 Add the following line of code to FirstViewController.h file

#import <UIKit/UIKit.h>

@protocol MyDelegate

-(void)MyDelegateMethod:(NSString *)description;

@end

@interface FirstViewController : UIViewController

{



}

@property (nonatomic, weak) id MyDelegate;

Step 2 : To implement the above created delegate method one needs to add the below

mentioned code in SecondViewController.m file

@interface SecondViewController()<MyDelegate>

@end

@implementation SecondViewController

-(void)GoToFirst

{

FirstViewController *first = [[FirstViewController

alloc]initWithNibName:@"FirstViewController" bundle:Nil];

first.MyDelegate = self;

[self.navigationController pushViewController:cart animated:YES];

}

// Delegate Method Goes Here

-(void)MyDelegateMethod:(NSString *)description;

{

}

@end
