iphone - Saving application data state on exit -


I have an NSMutableArray with 24 strings.

I need to save this data if a user makes a call or leaves the application.

I see in many instances, but for some reason the best way to save data can not be determined.

The 24 strings correspond to 24 buttons and their state. When a button is clicked, it displays related array information for that button tag (0 - 23). What do I need to maintain, if 10 buttons and their data are clicked, what would be the best way to keep this data, so that it can be reloaded when the app starts?

I think I will need to store:

button tag, array value corresponding to buttons, button
(whether clicked and showing value or No)

I will store the application when I exit this data and then when the app is restarted, I will decide whether this stored data exists, if so, the array To determine the key and test the states of the button Whether it has been shown already and if so, then set it accordingly. Then when this file was loaded, I will destroy the stored data. In this way, if a user resigns, then in the next beginning, it will start a new game.

I have looked at several instances, where they store the data in a DAT file, but there is a problem applying this problem .... And thinking that this is also the best way.

Any help or idea is appreciated on this.

You can save data to a plist in the document directory Are there. If the data is there, then load it, and if not, it will suggest a clean run.

To load the data: 

  NSArray * path = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString * Document = [Path ObjectAddIndex: 0]; NSString * filePath = [document string: bubbing money company: @ "buttonstate.lilist"]; NSMutableDictionary * buttonState = [[NSMutableDictionary alloc] initWithContentsOfFile: filePath];

To save the data: 

  [buttonState writeToFile: filePath atomically: Yes];

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...
