아이폰 Navigation Controller 만들기 예제 따라하기

- 아이폰의  Navigation Controller 를 이용해서 View 전환 즉 화면 전환을 해보도록 하자.

- 화면 디자인

- Navigation Controller 만들기 순서

1. Xcode 실행

2. Utility Application
3. Project Name : “UtilityTest”
4. storyboard의 첫 번째 xib 파일에 Label 위치
5. Assistant Editor로 Label 드래그
6. “myLabel” 입력
7. @interface 라인 끝에서 “{” 엔터
8. “NSString *dispStr;”
9. storyboard의 두 번째 xib 파일에 Switch 위치
10. Assistant Editor로 Switch 드래그
11. “mySw” 입력
12. Assistant Editor로 Switch 드래그 – Connection을 “Action”으로 변경 

13. “changeSW” 입력
14. @interface 라인 끝에서 “{” 엔터
15. “NSString *myStr;” 입력
16. } 아래에 “@property(strong, nonatomi) NSString *myStr;” 입력
17. MainViewController.m 파일 편집

- (void)viewDidLoad
{ [super viewDidLoad];

dispStr = @"YES";

myLabel.text = dispStr; }

- (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller { dispStr = controller.myStr;

myLabel.text = dispStr;

[self dismissModalViewControllerAnimated:YES]; }

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([[segue identifier] isEqualToString:@"showAlternate"]) {

[[segue destinationViewController] setDelegate:self];

FlipsideViewController *viewController = (FlipsideViewController *)[segue destinationViewController];

viewController.myStr = dispStr; }

}

18. FlipsideViewController.m 파일 편집

@synthesize myStr; ...
- (void)viewDidLoad

{

[super viewDidLoad];

if (myStr == @"YES") { _mySw.on = YES;

} else {
_mySw.on = NO;

} }

- (IBAction)done:(id)sender

if (_mySw.on) { myStr = @"YES";

} else {
myStr = @"NO";

} }
