didReceiveData is not getting all data

Question

I am trying to download a JSON with NSURLConnection, but unless I force the app to pause some seconds the data I get isn't complete. It is always around 2600 bytes and my response should be around 70000.

Any clue why is this happening?

Thank You

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    _responseData = [[NSMutableData alloc] init];
    //sleep(10);
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [_responseData appendData:data];
    [self getDataJSON: _responseData];
}

Answer 1

didReceiveData is called a lot of times, while it is receiving data

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [_responseData appendData:data];

}

You have to wait until it finish receiving data

- (void)connectionDidFinishLoading:(NSURLConnection*)connection
{
     [self getDataJSON: _responseData];
}

Answer 2

You can get complete data when connection is finished. NSURLConnection finishes when it's connectionDidFinishLoading: delegate method is called. Try [self getDataJSON: _responseData]; in that method. Good Luck!
