Question

I’ve to switch a part of my app: I will implement a web view insread of a picture (imageview).

So I tried to make it with the interface builder but there is too many errors so I prefer to use code!

for the pictures, I user those lines :

image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
self.imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(0,64,320,367);
[self.view addSubview:imageView];
[self.imageView release];

Now, I tried to use this code but nothing’s showed:

@property (nonatomic, retain) IBOutlet UIWebView *webView;

…

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.fr"]]];
[self.view addSubview:webView];

If you know how to make …. would be nice for me,

THANKS!

Declare in your h file:

UIWebView *contentWebView;  

And also tell to your viewController that you will implement <UIWebViewDelegate>

In viewDidLoad Add:

    contentWebView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
    contentWebView.delegate = self;
    contentWebView.multipleTouchEnabled = YES;
    contentWebView.scalesPageToFit = NO;    
    [self.view addSubview:contentWebView];

In dealloc don’t forget to release the webView:

[contentWebView release];

And implement the delegate methods:

#pragma mark -
#pragma mark WebViewDelegates

- (void)webViewDidStartLoad:(UIWebView *)webView{   


}

- (void)webViewDidFinishLoad:(UIWebView *)webView{  

}

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{

}

And also you need to load an request. You can doit in viewDidLoad after you have added the webView to your view:

[contentWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"]]];
