I'm using webView on iOS to access a web page within a native application using the objective-c language as in the following example:
NSURL *url = [NSURL URLWithString:@"http://www.exemplo.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];
But I would like the page to be fully loaded if it automatically closes without the user having to interfere. I already looked in the NSURL documentation, but I did not find anything to help me with this.
First, add in your header file .h the delegate class for UIWebView :
@interface WebViewController : UIViewController <UIWebViewDelegate>
And so, in the implementation set the ownership of your UIWebView :
[_webView setDelegate:self];
And finally, the delegate method that will perform the action you want as soon as the page loads:
- (void)webViewDidFinishLoad:(UIWebView *)webView {
// Ação ao carregar página...
}
By "close the page", I do not quite understand what exactly this action you want, but I believe that from this method you can define.
In addition to using the delegate method of webView: webViewDidFinishLoad
- (void)webViewDidFinishLoad:(UIWebView *)webView {
// Ação chamada ao terminar de carregar a página...
// Recomendo adicionalmente uma ação para ser executada automaticamente após alguns segundos depois de carregada a pagina, seja para ocultar a webview ou apresentar uma mensagem ao usuário dizendo que foi com sucesso.
[self performSelector:@selector(hideWebView) withObject:nil afterDelay:2.0];
}
Also use the delegate method to handle page load error situations!
-(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{
//Trate os possíveis erros da carga da url aqui.
}
