Main Controller
Added the following to the ViewDidLoad where 'addButtonPress ed' deals with the processing
Code:
NSNotificationCenter.defaultCenter().addObserver(self, selector: "addButtonPressed", name: "addToList", object: nil)

I solved this using NSNotificationC enter - not sure that this is really the best method but anything that works when it comes to Swift is ok with me.

SWIFT: Trigger function from TableCell
Hi.
I have a ViewController, say HomeView.
It contains a TableView, say MyTable.
The table has a custom cell of class MyCell.
How can I assign delegates, protocol or whatever is needed to get a button click (addTarget method) within MyCell to trigger a function in main ViewController, HomeView?
I can't seem to use self, ParentViewContr oller, HomeView() to get error free code.

RestKit.h never found in xCode project
Hi.
My project was working and building just fine until I had to install a pod via Cocoapods which required so many attempts involving different versions, cleans, builds etc.
Now RestKit.h is never found by the bridging header file no matter what I try to do.
I note that this is seemingly a known issue with RestKit but I've spent 3 days already trying to get my project back and none of the following have... -

Importing 3rd party menu
Hi.
I'm trying to make use of the menu at https://github.com/kitasuke/PagingMenuContr oller. It all seems to be ok (no errors during coding) until i try to build the project.
It throws an error 'import PagingMenuContr oller' - No such module.
I've copied the files from Pod/Classes into my project as suggested by the docs. I put them amongst the project Swift files. I have also made sure the paths etc are... -
Nothing seems to fix this. It's a bit ridiculous as you would think this is pretty basic usage - just trying to get a specific file from the web.
Is there really no code that works in xCode 7 Swift 2.0?Leave a comment:

Many thanks for the reply zmbd - appreciate the help despite the lack of Swift experience.
Unfortunately the asterisk issue had been tried earlier and makes no difference - the part of the code underlined in red is the :@ as it seems to want to insert a ; in there but the line seems to be written exactly as code snippets suggest.
Even if I paste in the examples from the documentation I have the same issue so maybe this...Leave a comment:

xCode Swift NSString problem
Hi.
I'm learning Swift and struggling with a process for obtaining an image from the web via passing a parameter to a URL.
The code is as follows
...Code:NSString* myURLString = [NSString stringWithFormat:@"http://mydomain.com/uploads/%@", userimg]; NSURL* imageURL = [NSURL URLWithString:myURLString]; NSData* imageData = [NSData dataWithContentsOfURL:imageURL]; UIImage* image

Sorry - had to work on something else for a while and forgot all about this!
For my needs I managed to get good enough stability using the generic keep-alive functionality and tweaks to the requests but Chaarmann's method seems to be decent solution for more complex requirements.
Many thanks.Leave a comment:

Using Keep-Alive to retain connection for duration
Hi.
I am building an app that acquires data from a web service via HttpURLConnecti on. The app requests data every minute continuously whilst it is open and activated.
At the moment I am opening and closing the connection each time it is required but is it better practise to have a single connection that persists?
The current code is
...Code:URL url = new URL(tradeURL); connection

Android Studio: Copy textbox entry to webview page form
Hi.
I am trying to write a basic app in Android Studio (my first attempt).
I have an EditText field for a username and one for a password plus a button. I also have a WebView which will contain a webpage with a login form.
Since I'd like to keep the actual webpage hidden (as it is a mess on a phone device), I'd like to be able to type into the app form and have the app button transfer the data to the web... -
VS2010 for Windows Phone without Marketplace
Hi.
I am looking to write a personal application that I would like to run from a Windows Phone.
Is it possible to install the program to my phone without putting it in the Windows Phone Marketplace? This is not intended for public use, just for me.
I know Apple allow this sort of thing but there's a fee etc.
All I'd like to do is write a phone application in VS2010 and then install it on my personal... -
Double value 0.0 classed as Nothing?
Hi.
I am retrieving JSON data. Not all parameters are returned each time and some that are returned might be a double value of 0.0.
The problem is, I thought that I could just check if the parameter was returned by using the following....
...Code:'mydata is the parsed JSON response, value1 is a double value If Not mydata.value1 Is Nothing Then ' process Else 'ignore End

Excel file locked for editing
Hi,
I am making use of an Excel file in a form via the following process (edited for brevity).
When the form is disposed the following code should, I thought, release...Code:Imports Excel = Microsoft.Office.Interop.Excel Imports Microsoft.Office xlApp = New Excel.Application xlApp = CreateObject("Excel.Application") xlWorkBook = xlApp.Workbooks.Open(....) -
Thanks Gabe.
At the moment this seems to be eliminating the crashes so seems ok. Was a simpler solution than expected from reading the MSDN docs.
I have read somewhere that this will need adding to any threads opened by the main thread so will add there too. Not sure about backgroundWorke r threads.
Thanks for the assistance!Leave a comment:

Ok - seems the answer to the above is 'no' so I'm back to trying to force the culture :)Leave a comment:

This might be a stupid observation, but would simply changing the Language on the form to English(United Kingdom) force the culture on the form to en-GB for all users irrespective of their machine settings?Leave a comment:
