ios webview not showing up after setting delegate

Question

I'm setting up a webview programmatically, and everything works until I actually set the delegate.

MainPageViewController.h

#import <UIKit/UIKit.h>

@interface MainPageViewController : UIViewController <UIWebViewDelegate>

@property (nonatomic, strong) UIWebView *webViewForStories;

@end

MainPageViewController.m

- (void)viewDidLoad
{
    webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 300)];    
    NSString *urlAddress = @"http://myurl.com/mypage";
    NSURL *url = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [webView loadRequest:requestObj];
    [self.view addSubview:webView];

    webViewForStories = [[UIWebView alloc] initWithFrame:CGRectMake(0, webView.bounds.size.height, self.view.bounds.size.width, self.view.bounds.size.height)];

    NSString *urlAddressForStories = @"http://myurl.com/mysecondpage";
    NSURL *urlForStories = [NSURL URLWithString:urlAddressForStories];
    NSURLRequest *requestObjForStories = [NSURLRequest requestWithURL:urlForStories];
    [webViewForStories loadRequest:requestObjForStories];
    [self.view addSubview:webViewForStories];
    [webViewForStories setDelegate:self];

    NSLog(@"webviewForStories delegate is %@", webViewForStories.delegate);
    NSLog(@"webviewForStories is %@", webViewForStories);
}

Here's what the page looks like when I set the delegate:

Here's what the page looks like when I DON'T set the delegate:

The only difference is this line of code:

[webViewForStories setDelegate:self];

Here is the relevant output from NSLog:

2012-12-26 14:18:40.720 WGGB for iPad[3144:907] webviewForStories delegate is <MainPageViewController: 0x1f878cc0>
2012-12-26 14:18:40.721 WGGB for iPad[3144:907] webviewForStories is <UIWebView: 0x1f8838c0; frame = (0 300; 768 1004); layer = <CALayer: 0x1f883920>>

This is a mystery, any help is appreciated. FYI, I tried commenting out the first webview, I thought they might be conflicting, but it didn't make a difference.

EDIT:

Here are my delegate methods:

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
    NSLog(@"webview finished loading");
}

-(void)webViewDidStartLoad:(UIWebView *)webView
{
    NSLog(@"webview started loading");
}

// This function allows me to intercept links clicked in a webview and open in
// a navigation window with a back button.
-(BOOL) webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    NSURL *url = request.URL;
    NSString *urlString = url.absoluteString;

    NSLog(@"urlstring is %@", urlString);

    // Only catching links without "mobile" in the url (i.e. stories)
    if ([urlString rangeOfString:@"/mobile"].location == NSNotFound && [urlString rangeOfString:@"facebook"].location == NSNotFound && [urlString rangeOfString:@"facebook"].location == NSNotFound &&[urlString rangeOfString:@"twitter"].location == NSNotFound && [urlString rangeOfString:@"fb://"].location == NSNotFound && [urlString rangeOfString:@"liverail"].location == NSNotFound && [urlString rangeOfString:@"about:blank"].location == NSNotFound) {
        //DetailViewController *detailView = [[DetailViewController alloc] init];
        //[self.navigationController pushViewController:detailView animated:YES];

        return NO;
    } else {
        return YES;
    }
}

-(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
    NSLog(@"error is %@", [error localizedDescription]);
}

None of them seem to be getting called.

I figured it out... the problem was with this method:

// This function allows me to intercept links clicked in a webview and open in
// a navigation window with a back button.
-(BOOL) webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    NSURL *url = request.URL;
    NSString *urlString = url.absoluteString;

    NSLog(@"urlstring is %@", urlString);

    // Only catching links without "mobile" in the url (i.e. stories)
    if ([urlString rangeOfString:@"/mobile"].location == NSNotFound && [urlString     rangeOfString:@"facebook"].location == NSNotFound && [urlString rangeOfString:@"facebook"].location == NSNotFound &&[urlString rangeOfString:@"twitter"].location == NSNotFound && [urlString rangeOfString:@"fb://"].location == NSNotFound && [urlString rangeOfString:@"liverail"].location == NSNotFound && [urlString rangeOfString:@"about:blank"].location == NSNotFound) {
        //DetailViewController *detailView = [[DetailViewController alloc] init];
        //[self.navigationController pushViewController:detailView animated:YES];

        return NO;
    } else {
        return YES;
    }
}

The if statement was being caught on the initial loading of the webview so it was returning NO, which basically gave me a blank screen. I had to check if this was the initial load or not before allowing that if statement to run.

try setting the delegate to the property instead of the ivar.

[self.webViewForStories setDelegate:self] 

to get the webviews to call the delegate methods you have implemented.
