The connection failed due to a malformed URL
At CFNetwork Error Codes Reference
, i got the info that this error triggered by CFNetwork
- When and Why this error is triggered ?
- How to get rid from this error?
La solution
NSURLConnection has a method canHandleRequest which will return a boolean whether the url is valid or not, e.g.
NSString *strUrl = [NSString stringWithFormat:@"http://test.com/stopBoard/%i",busStopCode];
NSURL *url = [NSURL URLWithString:strUrl];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url
cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
timeoutInterval:20.0];
// a cache policy of NO must be used otherwise the previous query is used if the phone is not online
BOOL canGo = [NSURLConnection canHandleRequest:request];
if(canGo){
connection = [[NSURLConnection alloc] initWithRequest:request
delegate:self
startImmediately:YES];
} else {
self.errorMessage = @"\n\nurl check failed\n\n";
return NO;
}
