How do I create delegates in Objective-C?

Question

I know how delegates work, and I know how I can use them.

But how do I create them?

Answer 1

Answer is actually answered, but I would like to give you a "cheat sheet" for creating a delegate:

DELEGATE SCRIPT

CLASS A - Where delegate is calling function

@protocol <#Protocol Name#> 

-(void)delegateMethod;

@end

@interface <#Some ViewController#> : <#UIViewController#> 

@property (nonatomic, assign) id <<#Protocol Name#>> delegate;

@end


@implementation <#Some ViewController#> 

-(void)someMethod {
    [self.delegate methodName];
}

@end




CLASS B - Where delegate is called 

@interface <#Other ViewController#> (<#Delegate Name#>) {}
@end

@implementation <#Other ViewController#> 

-(void)otherMethod {
    CLASSA *classA = [[CLASSA alloc] init];

    [classA setDelegate:self];
}

-delegateMethod() {

}

@end
