ios - Calling NSURLConnection inside dispatch_async and reading didReceiveResponse in mainRunLoop in iPhone development -

-

First of all, it's random with me because this is my first iOS related question for SO.

Am I receiving feedback for the following methods 

  - (zero) connection: (NSURLConnection *) connection was the reception: (NSURLResponse *) response {} < / Code>

after calling it 

  NSURLConnection * conn = [[NSURL connection alloted] initWithRequest: request representative: self]; [Schedule Schedule Infinite Loop: [NSRunLoop mainRunLoop] forMode: NSDefaultRunLoopMode]; [to start];

one 

  inside sender_sink ();

but the connection method is not calling, but when I run NSURLConnection code out of dispatch_async I call this method,

What is the reason for this and how can I correct it? This is because the representative refers to self and self refers to the background thread but UIViewController is not the same class is?

Since you are making a connection to schedule in a loop and afterwards start, With the code> initWithRequest the startImmediately parameter is set to NO . Right now, you are starting the connection two times. And, more importantly, you are starting this before scheduling it in the main run loop.

To resolve this, specify NO as startImmediately : 

  NSURLConnection * conn = [ [NSURLConnection alloc] initWithRequest: Request Rep: Auto Start Import: No]; [Schedule Schedule Infinite Loop: [NSRunLoop mainRunLoop] forMode: NSDefaultRunLoopMode]; [to start];

By saying that, I do not need to send this code to everyone in the background queue (because initWithRequest runs asynchronously and somebody Only the time when I use the pattern above, since the time I use some custom NSOperation subclass (in which case, the above pattern is very useful) in your NSURLConnection is wrapping the request. But in this case, it is unnecessary.

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
