Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

UIWebView getting retained in ARC but Delegate methods are not being called

I am having an issue with ARC. It is not retaining the webview. The scenario is I have to send a webview from one viewcontroller to another one. The reason is when the user searches for something I want to take him to a new screen with some other options. (I have to use the same webview)

Here is the sample code: I have a ViewController1 which has a webview (I added it in the xib.) I am loading say google in it and once the user searches for something and when its done loading I have to take him to a new view controller and show the same webview in the new viewcontroller.


//ViewController1
@interface ViewController1 : UIViewController <UIWebViewDelegate>
    @property (nonatomic, retain) IBOutlet UIWebView* testWebView;
@end

@implementation ViewController1
@synthesize testWebView;
- (void)viewDidLoad
{
    [super viewDidLoad];
    [testWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@\"https://www.google.com\"]]];
}
-(void)webViewDidFinishLoad:(UIWebView *)webView{
    NSString *html = [testWebView stringByEvaluatingJavaScriptFromString: 
                      @\"document.body.innerHTML\"];
    if ([self.testWebView.request.url.absoluteString     rangeOfString:@\"output=search\"].location != NSNotFound) {
        ViewController2* newViewController = [[ViewController2 alloc] init];
        [newViewController setTestWebView:self.testWebView];
        [self.navigationController pushViewController:newViewController animated:YES];
    }
}
- (void)dealloc{
    [self.testWebView stopLoading];
    self.testWebView.delegate = nil;
    self.testWebView = nil;
}


In the second view controller I am loading stackoverflow.com after a delay of 10 secs. The problem is it is loading stackoverflow fine, but it is not calling any of the delegate methods. Why?


@interface ViewController2 : UIViewController <UIWebViewDelegate>
    @property (nonatomic, retain) UIWebView* testWebView;
@end

@implementation ViewController2
@synthesize testWebView;
- (void)viewDidLoad
{
    [super viewDidLoad];
    self.testWebView.delegate = self;
    [self.view addSubview:testWebView];
    [self performSelector:@selector(loadDifferentPage) withObject:nil afterDelay:10];
}

-(void)loadDifferentPage{
    [self.testWebView loadRequest:[NSURLRequest requestWithURL:[NSURL     URLWithString:@\"http://www.stackoverflow.com/\"]]];
}

-(void)webViewDidStartLoad:(UIWebView *)webView{
    NSLog(@\"%s\", __PRETTY_FUNCTION__);
}

-(void)webViewDidFinishLoad:(UIWebView *)webView{
    NSLog(@\"%s\", __PRETTY_FUNCTION__);
}

-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
    NSLog(@\"%s\", __PRETTY_FUNCTION__);
    return YES;
}



ViewController2 is retaining the webview but the delegate methods are not being called. Why?

Thanks Sai
