Question

如何在iOS中为UIScrollView UIImageView添加页面控件。如果我选择了某些页面控制项目符号，则表示我想移动所选图像。如果我移动图像意味着我的pagecontrol项目符号也想要移动到UIScrollView。

 - (void)viewDidLoad
{
    NSLog(@"Welcome to Home Page");
    [super viewDidLoad];

   // self.view.backgroundColor=[[UIColor alloc]initWithPatternImage:[UIImage imageNamed:@"bg-image.png"]];

    UIImage * img = [UIImage imageNamed:@"bg-image.png"];
    [scrollView setBackgroundColor:[UIColor colorWithPatternImage:img]];
// Do any additional setup after loading the view, typically from a nib.
}



- (void)loadView {


    CGRect fullScreenRect=[[UIScreen mainScreen] applicationFrame];
    scrollView=[[UIScrollView alloc] initWithFrame:fullScreenRect];
    scrollView.contentSize=CGSizeMake(1400, 100);

    UIImageView *tempImageView2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sti01.png"]];
    tempImageView2.frame=CGRectMake(10, 60, 200, 200);
    [scrollView addSubview:tempImageView2];


    UIImageView *tempImageView3 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sti02.png"]];
    tempImageView3.frame=CGRectMake(240, 60, 200, 200);
    [scrollView addSubview:tempImageView3];

    UIImageView *tempImageView4 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sti03.png"]];
    tempImageView4.frame=CGRectMake(470, 60, 200, 200);
    [scrollView addSubview:tempImageView4];

    UIImageView *tempImageView5 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sti04.png"]];
    tempImageView5.frame=CGRectMake(700, 60, 200, 200);
    [scrollView addSubview:tempImageView5];


    UIImageView *tempImageView6 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sti05.png"]];
    tempImageView6.frame=CGRectMake(930, 60, 200, 200);
    [scrollView addSubview:tempImageView6];

    UIImageView *tempImageView7 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"sti06.png"]];
    tempImageView7.frame=CGRectMake(1160, 60, 200, 200);
    [scrollView addSubview:tempImageView7];



    self.view=scrollView;
    [scrollView addSubview:tempImageView2];
    [scrollView addSubview:tempImageView3];
    [scrollView addSubview:tempImageView4];
    [scrollView addSubview:tempImageView5];
    [scrollView addSubview:tempImageView6];
    [scrollView addSubview:tempImageView7];

    scrollView.userInteractionEnabled = YES;
    btn = [UIButton buttonWithType:UIButtonTypeCustom];
    btn.frame = CGRectMake(22, 100, 1800, 500);
   // [btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [btn addTarget:self action:@selector(buttonTest:) forControlEvents:UIControlEventTouchUpInside];    
    [scrollView addSubview:btn];


}


- (IBAction)buttonTest:(id)sender {
    MSDescriptionpage *aSecondPageController = [[MSDescriptionpage  alloc] initWithNibName:@"MSDescriptionpage" bundle:nil];        
    [self.navigationController pushViewController:aSecondPageController animated:YES];        
    [aSecondPageController release];

}

我必须这样做，我做的是我使用了两个视图控制器（用于页面滑动的页面视图控制器）和具有UIImage视图的主视图控制器，您可以在此处添加带有图像的滚动视图。 这些在VC页面中里面加载了

  [pageController setViewControllers:viewControllers  
                             direction:UIPageViewControllerNavigationDirectionReverse  
                              animated:NO 
                            completion:nil];

    [self addChildViewController:pageController];
    [[self view] addSubview:[pageController view]];
    for (UIGestureRecognizer *gR in pageController.gestureRecognizers) {
        gR.delegate = self;
    }
    [pageController didMoveToParentViewController:self];}

这些调用另一个vc

- (UIViewController *)pageViewController:
(UIPageViewController *)pageViewController viewControllerBeforeViewController:
(UIViewController *)viewController
{
    for (UIGestureRecognizer *recognizer in pageController.gestureRecognizers) {
        if ([recognizer isKindOfClass:[UITapGestureRecognizer class]]) {
            recognizer.enabled = NO;
        }
    }
    NSUInteger index = [self indexOfViewController:
                        (MainViewController *)viewController];
    if ((index == 0) || (index == NSNotFound)) {
        return nil;
    }

    index--;
    return [self viewControllerAtIndex:index];
}
