Comment puis-je effectuer une pagination dans UIWebView?

Question

J'ai dix fichiers HTML locaux dans mon dossier de ressources et je veux effectuer l'effet de pagination comme ScrollView et ImageView alors s'il vous plaît aidez-moi comment je peux le faire. J'ai affiché la page HTML en webView, mais je n'ai plus d'idées. Mon code est (mais il est pour une seule page):

arrHtmlPage=[[NSMutableArray alloc] initWithObjects:@"2",@"3",@"5",@"6",@"8",@"9",@"11",@"13",nil]; 

NSBundle *bundle = [NSBundle mainBundle]; 

NSString *htmlTemplateLink = [bundle pathForResource:@"2" ofType:@"htm"]; 

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:htmlTemplateLink]]; 

wview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 768, 940)]; 
wview.scalesPageToFit = YES; 
[wview loadRequest:request]; 
wview.delegate=self; 

//wview.multipleTouchEnabled=YES; 
wview.userInteractionEnabled=YES; 

[self.view addSubview:wview];

const CGFloat kScrollObjHeight = 900; 

const CGFloat kScrollObjWidth = 766; 

const NSUInteger kNumImages = 11; 



- (void)layoutScrollImages 

{ 

    UIImageView *view = nil; 
    NSArray *subviews = [scrollView1 subviews]; 


    // reposition all image subviews in a horizontal serial fashion 
    CGFloat curXLoc = 0; 
    for (view in subviews) 
    { 
     if ([view isKindOfClass:[UIWebView class]] && view.tag > 0) 
     { 
      CGRect frame = view.frame; 
      frame.origin = CGPointMake(curXLoc, 0); 
      view.frame = frame; 

      curXLoc += (kScrollObjWidth); 
     } 
    } 

    // set the content size so it can be scrollable 
    [scrollView1 setContentSize:CGSizeMake((kNumImages * kScrollObjWidth), [scrollView1 bounds].size.height)]; 
} 

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    arrHtmlPage=[[NSMutableArray alloc] initWithObjects:@"",@"2",@"3",@"4",@"5",@"6",@"8",@"9",@"11",@"12",@"13",@"14",nil]; 

    [scrollView1 setBackgroundColor:[UIColor blackColor]]; 
    [scrollView1 setCanCancelContentTouches:NO]; 
    scrollView1.indicatorStyle = UIScrollViewIndicatorStyleWhite; 
    scrollView1.clipsToBounds = YES;  // default is NO, we want to restrict drawing within our scrollview 
    scrollView1.scrollEnabled = YES; 

    // pagingEnabled property default is NO, if set the scroller will stop or snap at each photo 
    // if you want free-flowing scroll, don't set this property. 
    scrollView1.pagingEnabled = YES; 



    int i; 
    for (i = 0; i <[arrHtmlPage count]; i++) 
    { 

     NSBundle *bundle = [NSBundle mainBundle]; 

     NSString *htmlTemplateLink = [bundle pathForResource:[arrHtmlPage objectAtIndex:i] ofType:@"htm"]; 

     NSLog(@"htmlTemplateLink==>%@",htmlTemplateLink); 

     NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:htmlTemplateLink]]; 
     wview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 766, 940) ]; 
     wview.backgroundColor=[UIColor redColor]; 
     wview.tag=i; 
     wview.scalesPageToFit = YES; 
     [wview loadRequest:request]; 

     wview.userInteractionEnabled=YES; 

     [scrollView1 addSubview:wview]; 


    } 

    [self layoutScrollImages]; 

} 



-(IBAction)buttonPressed:(id)sender 
{ 

    int pageNo = [sender tag] ; // current page no 
    int tempNo = pageNo%10 + 1; // total count 

    CGPoint bottomOffset = CGPointMake((tempNo-1) * 768,0); 
    [scrollView1 setContentOffset:bottomOffset animated:YES]; 
}

dans Xcode 4.3.1 créer un nouveau projet. Fichier -> Nouveau projet -> Application basée sur des pages. Faites glisser et déposez un UIWebView sur le storyboard.
