I am new to trying to create a book app adapting the page-based application of the new xcode just using the single view app, because it is quite confusing learning the template.
i found this code and i am trying to replace the HTML content of this work to UIImageView but i failed.
- (void) createContentPages
{
NSMutableArray *pageStrings = [[NSMutableArray alloc] init];
for (int i = 1; i < 11; i++)
{
NSString *contentString = [[NSString alloc]
initWithFormat:@"<html><head></head><body><h1>Chapter %d</h1><p>This is the page %d of content displayed using UIPageViewController in iOS 5.</p></body></html>", i, i];
[pageStrings addObject:contentString];
}
pageContent = [[NSArray alloc] initWithArray:pageStrings];
}
what i am trying to is to display different images per page.
here is what i did. (i know it is so wrong i just tried it)
- (void) createContentPages
{
NSMutableArray *pageStrings = [[NSMutableArray alloc] init];
for (int i = 1; i < 11; i++)
{
NSArray *photos = [[NSArray arrayWithObjects:
[UIImage imageNamed:@"p1.png"],
[UIImage imageNamed:@"p2.png"],
[UIImage imageNamed:@"p3.png"],
[UIImage imageNamed:@"p4.png"],
nil];
[pageStrings addObject:photos];
}
pageContent = [[NSArray alloc] initWithArray:pageStrings];
}
and it has UIWebView in each page. is it possible that if i replace it with UIImageView it will run?
Here’s the rest of the code:
- (void)viewDidLoad
{
[super viewDidLoad];
[self createContentPages];
NSDictionary *options =
[NSDictionary dictionaryWithObject:
[NSNumber numberWithInteger:UIPageViewControllerSpineLocationMin]
forKey: UIPageViewControllerOptionSpineLocationKey];
self.pageController = [[UIPageViewController alloc]
initWithTransitionStyle:UIPageViewControllerTransitionStylePageCurl
navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal
options: options];
pageController.dataSource = self;
[[pageController view] setFrame:[[self view] bounds]];
contentViewController *initialViewController =
[self viewControllerAtIndex:0];
NSArray *viewControllers =
[NSArray arrayWithObject:initialViewController];
[pageController setViewControllers:viewControllers
direction:UIPageViewControllerNavigationDirectionForward
animated:NO
completion:nil];
[self addChildViewController:pageController];
[[self view] addSubview:[pageController view]];
[pageController didMoveToParentViewController:self];
}
- (contentViewController *)viewControllerAtIndex:(NSUInteger)index
{
// Return the data view controller for the given index.
if (([self.pageContent count] == 0) ||
(index >= [self.pageContent count])) {
return nil;
}
// Create a new view controller and pass suitable data.
contentViewController *dataViewController =
[[contentViewController alloc]
initWithNibName:@"contentViewController"
bundle:nil];
dataViewController.dataObject =
[self.pageContent objectAtIndex:index];
return dataViewController;
}
- (NSUInteger)indexOfViewController:(contentViewController *)viewController
{
return [self.pageContent indexOfObject:viewController.dataObject];
}
- (UIViewController *)pageViewController:
(UIPageViewController *)pageViewController viewControllerBeforeViewController:
(UIViewController *)viewController
{
NSUInteger index = [self indexOfViewController:
(contentViewController *)viewController];
if ((index == 0) || (index == NSNotFound)) {
return nil;
}
index--;
return [self viewControllerAtIndex:index];
}
- (UIViewController *)pageViewController:
(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController
{
NSUInteger index = [self indexOfViewController:
(contentViewController *)viewController];
if (index == NSNotFound) {
return nil;
}
index++;
if (index == [self.pageContent count]) {
return nil;
}
return [self viewControllerAtIndex:index];
}
on subclass
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[webView loadHTMLString:dataObject
baseURL:[NSURL URLWithString:@""]];
}
All time you may use the pictures inside HTML page using the HTML tag
<IMG>. So, no the reason to use UIImageView.
