Test if internet connection is available

[mirap]

Hi!
I read all the posts here and there is currently no working solution for setting timeout. Fe.: wait(20000); writes "Passing argument 1 of wait makes pointer from integer without a cast"...

Is there any way how to create timeout for:

- (BOOL) connectedToNetwork
{
return ([NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.google.com"] encoding:NSASCIIStringEncoding error:nil]!=NULL)?YES:NO;
}
?

Thanks a lot.

your code didnt work because you are returning

yu need to take out the return you have and instead assign the results to a bool variable and test that in the if statement, you cant put if(YES) because YES is a constant, it will always go into the if statement

here is a simple code that works for iPhone webview error.


in the .h file add:

IBOutlet UIWebView *webView;

in the .m file add:

}
- (void)webViewUIWebView *)webView didFailLoadWithErrorNSError *)error {

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"WebView did not load. Please check your internet connection and re-launch the app." delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
[alert show];
[alert release];

}

- (void)viewDidLoad {
[super viewDidLoad];

[webView loadRequest: [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://whatever.com"]]];
