0. 목적 및 동기
요구되는 디자인이 기본 UIPageControl의 UI를 사용하지 않는다.
그래서 CustomPageControl 이 필요해졌다.
UI control구조에 익숙한 사람이라면 control 들은
subcontrol 들의 조합으로 이루어 졌다는 사실을 예상할 수 있을것이다.
UIPageControl 도 마찬가지로 점들을 이루는 UIImageView 가
subcontrol 로 존재한다.
1. 코드
@interface CustomPageControl : UIPageControl {
}
@end
#import "CustomPageControl.h"
#define kOffImage [UIImage imageNamed:@"offImage.png"]
#define kOnImage [UIImage imageNamed:@"onImage.png"]
@implementation CustomPageControl
- (void)layoutSubviews{
[super layoutSubviews];
UIImage* image = kOffImage;
for(UIImageView* view in self.subviews){
CGRect frame = view.frame;
frame.size = image.size;
view.frame = frame;
view.image = image;
}
}
- (void)setCurrentPage:(int)index{
[super setCurrentPage:index];
for(int i = 0 ; i < [self.subviews count] ; i++){
UIImageView* view = [self.subviews objectAtIndex:i];
view.image = (i == index) ? kOnImage : kOffImage;
}
}
@end
#import "Page2ViewController.h"
#import "Page1ViewController.h"
#import "popToViewControllerViewController.h"
@implementation popToViewControllerViewController
- (void)viewDidUnLoad{
[[NSNotificationCenter defaultCenter] removeObserver:self name:@"goPage2" object:nil];
}
- (void)viewDidLoad{
self.title = @"root";
self.view.backgroundColor = [UIColor yellowColor];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(goPage2) name:@"goPage2" object:nil];
UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(100,100,100,100)];
[button setTitle:@"go page 1" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button addTarget:self action:@selector(goPage1) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
[button release];
}
- (void)goPage1{
Page1ViewController* viewController = [[Page1ViewController alloc] init];
[self.navigationController pushViewController:viewController animated:YES];
[viewController release];
}
- (void)goPage2{
[self.navigationController popToViewController:self animated:NO];
Page2ViewController* viewController = [[Page2ViewController alloc] init];
[self.navigationController pushViewController:viewController animated:YES];
[viewController release];
}
@end
@implementation Page1ViewController
- (void)viewDidLoad{
self.title = @"page1";
self.view.backgroundColor = [UIColor redColor];
UIButton* button = [[UIButton alloc] initWithFrame:CGRectMake(100,100,100,100)];
[button setTitle:@"go page 2" forState:UIControlStateNormal];

dll 참조처럼 아이폰 OS에서 모듈참조하기
1. 참고

http://blog.stormyprods.com/2008/11/using-static-libraries-with-iphone-sdk.html
2. 테스트
테스트를 위해 프로젝트를 2개 만듬
- 2-0. library(static library project) 와 test(view-based application,library 테스트프로젝트)로 명명
- 2-1. device 와 simulator 파일을 구분하기 위해 product name 을 수정 (그림1)
- 2-2. library build(device & simulator)
- 2-3. test project 에 ".a" 파일 추가(2-2 의 빌드파일) (그림2)
- 2-4. test project 의 header search paths 추가 (library 의 header 파일이 있는 경로로 수정) (그림3)
- 2-5. test project 빌드
3. 결과물
