How to run HTML+javascript file run on UIWebView . .?

Question

Everybody,

I have a one HTML page which contain one Javascript function which shows one animals animation.. i have added it locally in to xcode project.

Now when i load this file in UIWebView it will looks perfect.. Here is the code of loading HTMl file to UIWebView

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"elephant-animation" ofType:@"html"] isDirectory:NO];
        NSURLRequest *req = [NSURLRequest requestWithURL:url];
        [self performSelectorOnMainThread:@selector(startWebLoad3:) withObject:req waitUntilDone:YES];

-(void)startWebLoad3:(NSURLRequest *)request
{
    [wbView3 loadRequest:request];
    [wbView3 setBackgroundColor:[UIColor clearColor]];
    wbView3.scrollView.scrollEnabled = NO;
    [wbView3.scrollView setBackgroundColor:[UIColor clearColor]];
    [wbView3 setOpaque:NO];
}

But i have 6 pages. When start to load every page with separate UIWebView, It goes to memory warning.. And give me error like here.

void SendDelegateMessage(NSInvocation*): delegate (webView:didFinishLoadForFrame:) failed to return after waiting 10 seconds. main run loop mode: kCFRunLoopDefaultMode

if i run only one page than it run perfectly, but when i start to load all together or one by one it crashed with memory warning.

Let me know if any one get any solution of it..

i have stuck with this problem..

Thanks,

i have searched on many forums and googling it, but dont get any luck... please help me.. — Solid Soft

I think load 6 pages each for 6 UIWebView is not necessary, is there any alternative way to make it? — Tom

@Raju Change Java script.. to make feasible in iOS - Objective C.. "JavaScript execution time is limited to 10 seconds for each top-level entry point. If your script executes for more than 10 seconds, the web view stops executing the script" — Solid Soft

finally i got solution.. After long R & D, got some effective solution...

"JavaScript execution time is limited to 10 seconds for each top-level entry point. If your script executes for more than 10 seconds, the web view stops executing the script"

this is the reason why i fail to load html page in UIWebView.. And iPad handle up to 3 MB data loading on App launch only.. And i have used more than it..

So, i change javascript as per requirement and now worked..

Thanks for be part of it..

static NSInteger currentIndex = 0;
if (currentIndex < 99) {
    currentIndex++;
}
NSString *path = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"file%d",currentIndex] ofType:@"html"];
NSFileHandle *readHandle = [NSFileHandle fileHandleForReadingAtPath:path];
NSString *htmlString = [[NSString alloc] initWithData: 
                        [readHandle readDataToEndOfFile] encoding:NSUTF8StringEncoding];
[self.myWebView loadHTMLString:htmlString baseURL:nil];

I hope it will work

i think,you want to do html file in webview ,in my application i done one scrollview in that view ,in that view i add webview in loop at last i add the html file in webview. try this code:

ScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0,0,768,[[UIScreen mainScreen] bounds].size.height)];
    ScrollView.contentSize = CGSizeMake(768*21,[[UIScreen mainScreen] bounds].size.width);
    ScrollView.pagingEnabled=YES;
    ScrollView.delegate = self;
    ScrollView.userInteractionEnabled = YES;
    ScrollView.showsVerticalScrollIndicator=NO;
    ScrollView.showsHorizontalScrollIndicator=NO;

    int x=0,y=125;
    for ( i=1; i<22; i++)
    {

        view3=[[UIView alloc]initWithFrame:CGRectMake(x,0,768, 1000)];
        view3.backgroundColor=[UIColor whiteColor];

        webview2=[[UIWebView alloc]initWithFrame:CGRectMake(0,y,768,755)];
        webview2.scalesPageToFit=YES;
        webview2.autoresizingMask=(UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);
        webview2.multipleTouchEnabled=YES;
        webview2.backgroundColor=[UIColor whiteColor];

        NSString *st = [NSString stringWithFormat:@"1%d",i];
        NSString *str12=[NSString stringWithFormat:@"information_"];
        str12=[str12 stringByAppendingString:st];
        NSString *urlAddress        = [[NSBundle mainBundle] pathForResource:str12 ofType:@"html"];//you can also use PDF files
        NSURL *url                  = [NSURL fileURLWithPath:urlAddress];
        NSURLRequest *requestObj    = [NSURLRequest requestWithURL:url];
        [webview2 loadRequest:requestObj];

        webview2.tag= i + 10;
        [view3 addSubview:webview2];


        [ScrollView addSubview:view3];

        x=x+768;


}
    [self.view addSubview:ScrollView];



}

in my application 22 html pages(information_%i,must in resource ) add in webview ,it is working very well.

i hope it's helpful to u also.
