ios - Passing information back from UITableViewDataSource to ViewController -

-

I have ViewController with a UITableView as I wanted to divide data handling, I prepared my class, Who responds to the UITWAdAdvertisers.

This class should first get data from CoreData and later from a REST API.

How did the datasource talk back to the ViewController to tell it to reload the tableView to call the data? Thought of:

  • Data sources data KVO and when the array changes call reloadData Datasource is assigned every time Datasource is assigned with a block ( [self.table reloadData] ), in the data source
  • Table Make the property public ViewController therefore datasource reloadData (which I can not really like as an idea)
  • A property on datasource A representative (which I feel like a loop), which can hold visual controller to use as a table,

    Is there any smart way to do this? ? Or how to solve it in a normal way? Update:

    I am not interested in code.

    Without more detail, it seems that you need a callback here. There are several ways that will work if you have 1 to 1 relationship (which means that your datasource needs to talk to the VC only), then this is a good case:

    1.) One Representative create your own representative protocol for your data source and then the VC will follow that protocol (delegate).

    2. Do this by using only one block for callback.

    The KVO will work just fine, but the situation above is more according to your scenario.

    You can add a table view property to your custom data source, but then why did you create that category in the first place < / Html>

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
