SubView에서 MainView 객체 컨트롤하기

ViewController.h

@protocol MainDelegate

- (void)didReceiveTest:(NSString *)message1 Message2(NSString *)message2;

@end

@interface ViewController : UIViewController <MainDelegate>

ViewController.m

// SubView로부터 받은 값 셋팅

- (void)didReceiveTest: (NSString *)message1 Message2(NSString *)message2{

    NSLog(@"SubView에서 호출");

    //객체 컨트롤 코드

}

//( addSubview ) 부모 웹뷰 자바스크립트 함수 호출이 안됨

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

appDelegate.moveUrl = URL; //SubView 에 웹뷰를 사용하기 때문에-

                

CGRect screenRect=[[UIScreen mainScreen]bounds];

CGFloat deviceWidth=screenRect.size.width;

CGFloat deviceHeight=screenRect.size.height;

                 

[_popUpViewController.view setFrame:CGRectMake(0, 0, deviceWidth, deviceHeight)];

_popUpViewController=[[PopView alloc]initWithNibName:@"PopView" bundle:nil];

_popUpViewController.delegate = self; //부모 오브젝트 컨트롤을 위해 딜리게이트 적용

[self.view addSubview:_popUpViewController.view];

PopView.h

@protocol MainDelegate;

@interface PopView : UIViewController <UIWebViewDelegate>{

    __unsafe_unretained id<MainDelegate> delegate;

}

@property (nonatomic, assign) IBOutlet id<MainDelegate> delegate;

PopView.m

#import "ViewController.h"

@implementation PopView

@synthesize delegate;

// MainView의 함수 호출

[delegate didReceiveTest:value01 Message:value02];

참고원문 

- 부모 뷰 컨트롤러 : ParentViewController
- 자식 뷰 컨트롤러 : ChildViewController
로 정의하고 시작.

1. 부모에 delegate @protocol 선언
2. 자식에서 같은 @protocol 코딩
3. 자식에서 부모에서 선언한 delegate 따른다고 선언
4. 자식에서 해당 delegate를 통하여 부모의 object 제어

ParentViewController.h :
