Question

I’m making an app that downloads data from a plist and uses that data in a tableview. Is there a way to check whether a connection to a url is successful and then whether the download was successful? Or maybe a tutorial that implements something like this?

Thanks

Answer 1

you must implement this delegate of NSURLConnection

//send the request
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

in the case of connection failure,this method will be executed

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
NSlog(@"no connection");
}
