Try this
// URL string encoding

NSString *escapedUrl = [aURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

// create the request

 NSURLRequest *aRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:escapedUrl]cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; 

// create the connection with the request
// and start loading the data

NSURLConnection *aConnection=[[NSURLConnection alloc] initWithRequest:aRequest delegate:self];
