uinavigationcontroller - iOS navigation views with both "back" and "save" buttons? -

-

I'm new to iOS programming and need some help on creating navigation. I have a top-level view shown on left when the user presses the "Create New" button, then the app must be brought up "A journal entry" view, which is right .

I have applied two views with navigation using the Navigation Controller. The problem I am aware of is that There are now two ways to navigate away : (1) using the upper-back back button and (2) using the "save" button, which saves File. I think the back button should go back without saving, or maybe the "cancel" button instead, in this case I should not use the navigation controller.

What is the standard UI approach of this type of problem?

I think That is, you should not change the architecture of your thoughts, it is very good and easy by going back to the previous view controller and saving the button by using the upper-left button, which IBAction 

  - (IBAction) doSaveStuff: (UIButton *) Sender {// Savings Content [self.navigationController popViewControllerAnimated: Yes]; }

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...
