  • Changing pointer of self

    - by rob5408
    I have an object that I alloc/init like normal just to get a instance. Later in my application I want to load state from disk for that object. I figure I could unarchive my class (which conforms to NSCoding) and just swap where my instance points to. To this end I use this code... NSString* pathForDataFile = [self pathForDataFile]; if([[NSFileManager defaultManager] fileExistsAtPath:pathForDataFile] == YES) { NSLog(@"Save file exists"); NSData *data = [[NSMutableData alloc] initWithContentsOfFile:pathForDataFile]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; [data release]; Person *tempPerson = [unarchiver decodeObjectForKey:@"Person"]; [unarchiver finishDecoding]; [unarchiver release]; if (tempPerson) { [self release]; self = [tempPerson retain]; } } Now when I sprinkled some NSLogs throughout my application I noticed self.person: <Person: 0x3d01a10> (After I create the object with alloc/init) self: <Person: 0x3d01a10> (At the start of this method) tempPerson: <Person: 0x3b1b880> (When I create the tempPerson) self: <Person: 0x3b1b880> (after i point self to the location of the tempPerson) self.person: <Person: 0x3d01a10> (After the method back in the main program) What am I missing?

  • How to create the automatic mass form submitter (javascript-ajax script) to be used on the 3rd part

    - by Daniel
    I need a script that can handle the following tasks. Take user data from my database and fill in and submit / post data to forms located on third part websites.: So I want to know if is it hard to create or do somebody knows if does exists some script for mass form submissions in PHP -Javascript-Ajax ? I run Dancers & Hostess & Model jobs website, I would like to find some script which allows the girls automaticly submit to hundreds websites forms (other 3rd part model agencies) with their similar model application form info on my website previously specified, 1).Firstly the girls will fill out my agency portfolio very detailed form , like this i will get all the model personal info from them , 2) Secondly i would like to allow for example models to submit to 100 and more other model agencies forms (I will find those websites before, and I will get their field names = values and thanks to some script would like to connect them with every girl data already created in my website to submit . I would like to implement it to my wordpress website where the girls has their portfolios instead of my pages . I would like to offer this service especially to models , it should work like some directory submitters , The script knows names - values and fill it out itself, but I want it online - browser side, where the girls should only fill out captcha if there is and click the button "submit".After succesful submit it should offer other form to submit. I would be very happy if you know the answer or if you can redirect me to some article

  • JBoss admin-console fails to load - missing Log4J jar?

    - by Jack
    I downloaded JBoss 5.1 and unzipped to ~/jboss/ such that JBoss is installed into: ~/jboss/jboss-5.1.0.GA/ I run the default deployment by using the following command found in jboss/jboss-5.1.0.GA/bin ./run.sh -c default While JBoss starts (http://127.0.0.1:8080/), admin-console is not deployed. The log file: jboss/jboss-5.1.0.GA/server/default/log shows the following information: DEPLOYMENTS IN ERROR: Deployment "vfsfile:/Users/jackwootton/jboss/jboss-5.1.0.GA/server/default/deploy/admin-console.war/" is in error due to the following reason(s): org.jboss.deployers.spi.DeploymentException: URL file:/Users/jackwootton/jboss/jboss-5.1.0.GA/server/default/tmp/az6n6v-tjilfb-h32fokxn-1-h32fosuo-v/admin-console.war/ deployment failed Deployment "vfszip:/Users/jackwootton/jboss/jboss-5.1.0.GA/server/default/deploy/quartz-ra.rar/" is in error due to the following reason(s): org.apache.commons.logging.LogConfigurationException: User-specified log class 'org.apache.commons.logging.impl.Log4JLogger' cannot be found or is not useable. The Log4J jar file exists in: jboss/jboss-5.1.0.GA/lib/jboss-logging-log4j.jar I have three questions: Have I understood the problem correctly (i.e. that admin-console cannot find the required Log4j JAR file and therefore is not deployed)? What can I do to fix this problem? Why would an out-of-the-box deployment have this problem in the first place?

  • Visual Studio 2010 is not allowing me to debug my code

    - by Tejs
    So, this interesting issue has been plaguing me for the past couple of hours. Visual Studio 2010 Ultimate no longer attaches the debugger and lets me debug my code. If I use the built in development server, then everything works fine. If I switch to Use Local IIS Web Server (http://localhost/), then all it does it attach to w3wp.exe, but no DLLs or PDBs are loaded for anything. I can go to Debug Windows Modules, and literally nothing is loaded in this window. Conversely, when using the built in development server, the Modules window displays all the DLLs and shows that the symbols for my DLLs have been loaded. Something is obviously amiss. The VS installation is completely bone stock. In IIS, my website is configured with ASP.NET 2.0 (because no 3.5 exists to select from the drop down), along with read / log visits / index this resource options checked on the "Home Directory" tab. Some of my failed ideas: 1) If I attach to process on the iexplore.exe instance where the website is displayed, it loads Internet Explorer's DLLs, but not mine. 2) I've restarted the computer multiple times 3) I've invoked devenv.exe /resetuserdata once 4) I've confirmed that every project is indeed set to debug and not release. 5) Deleted all \bin contents and rebuilt the solution. 6) Deleted entire solution and repulled from Source Control. Can someone tell me what is wrong with this thing? I'm going to have an aneurism from the headache this is causing me.

  • Emacs hide/show support for C++ triple-slash Doxygen markup?

    - by jsyjr
    I use Doxygen's triple-slash syntax to markup my C++ code. There are two important cases which arise: 1) block markup comments which are the sole element on the line and may or may not begin flush left; e.g. class foo /// A one sentence brief description of foo. The elaboration can /// continue on for many lines. { ... }; void foo::bar /// A one sentence brief description of bar. The elaboration can /// continue on for many lines. () const { ... } 2) trailing markup comments which always follow some number of C++ tokens earlier on the first line but may still spill over onto subsequent lines; e.g. class foo { int _var1; ///< A brief description of _var1. int _var2; ///< A brief description of _var2 ///< requiring additional lines. } void foo::bar ( int arg1 ///< A brief description of arg1. , int arg2 ///< A brief description of arg2 ///< requiring additional lines. ) const { ... } I wonder what hide/show support exists to deal with these conventions. The most important cases are the block markup comments. Ideally I would like to be able to eliminate these altogether, meaning that I would prefer not to waste a line simply to indicate presence of a folded block markup comment. Instead I would like a fringe marker, a la http://www.emacswiki.org/emacs/hideshowvis.el /john

  • Replacing/Adding resources (icon) programmatically in c#?

    - by reverendo
    I am trying to replace (or add in the case it doesn't exists) icons from .exe files using c#. So far I got this: string filename = "c:\\test.exe"; IntPtr hResource = BeginUpdateResource(filename, true); if (hResource.ToInt32() == 0) throw new Exception("File Not Found"); byte[] ico = System.IO.File.ReadAllBytes("C:\\icon.ico"); IntPtr unmanagedPointer = Marshal.AllocHGlobal(ico.Length); Marshal.Copy(ico, 0, unmanagedPointer, ico.Length); if (UpdateResource(hResource, "Icon", "1", 1033, unmanagedPointer, Convert.ToUInt32(ico.Length)) != false) { MessageBox.Show("Updated"); EndUpdateResource(hResource, false); } Marshal.FreeHGlobal(unmanagedPointer); "Icon", "1", 1033 <- I got this data by opening test.exe with Resource Hacker. I do get the messagebox "Updated", and if I open the resulting exe in Resource Hacker the resource gets replaced but the icon doesn't appear, its just empty. Also that code wont replace, the type "Icon" in the resource, it will delete everything and add that "Icon" and if I use BeginUpdateResource(path, false); it will not replace it neither but it will add ANOTHER "Icon". Where can I find an example to replace/add the icon using c# disregarding the name the resource use for the icon or if the resource doesn't exist?

  • Invalid Pointer Operation, advice requested with debugging

    - by Xanyx
    I appear to have created code that is trashing memory. Having never had such problems before, i am now settign an Invalid Pointer Operation. In the following the value of the const string sFilename gets trashed after my call to PromptForXYZPropertiesSettings. // Allow the user to quickly display the properties of XYZ without needing to display the full Editor function PromptForXYZProperties(const sFilename:string; var AXYZProperties: TXYZProperties): boolean; var PropEditor: TdlgEditor; begin PropEditor:= TdlgEditor.create(nil); try PropEditor.LoadFromFile(sFilename); Other Details: Delphi 2007, Windows 7 64 bit, but can reproduce when testing EXE on XP REMOVING CONST STOPS PROBLEM FROM EXHIBITING (but presumably the problem is thus just lurking) PropEditor.PromptForXYZPropertiesSettings creates and shows a form. If I disable the ShowModal call then the memory is not trashed. Even though i have REMOVED ALL CONTROLS AND CODE from the form So I would like some advice on how to debug the issue. I was thinking perhaps watching the memory pointer where the sFilename var exists to see where it gets trashed, but not sure how i would do that (obviously needs to be done within the app so is owned memory). Thanks

  • Finding patterns of failure in a Unit Test

    - by Pekka
    I'm new to Unit Testing, and I'm only getting into the routine of building test suites. I have what is going to be a rather large project that I want to build tests for from the start. I'm trying to figure out general strategies and patterns for building test suites. When you look at a class, many tests come to you obviously due to the nature of the class. Say for a "user account" class with basic CRUD operations, being related to a database table, we will want to test - well, the CRUD. creating an object and seeing whether it exists query its properties change some properties change some properties to incorrect values and delete it again. As for how to break things, there are "fail" tests common to most CRUD classes like: Invalid input data types A number as the ID key that exceeds the range of the chosen data type Input in an incorrect character encoding Input that is too long And so on and so on. For a unit test concerned with file operations, the list of "breaking things" could be Invalid characters in file name File name too long File name uses incorrect protocol or path I'm pretty sure similar patterns - applicable beyond the unit test one is currently working on - can be found for most units that are being tested. Now my question is: Am I correct in seeing such "breaking patterns"? Or am I getting something completely wrong about Unit testing, and if I did it right, this wouldn't be an issue at all? Is Unit Testing as a process of finding as many ways to break the unit as possible the right way to go? If I am correct: Are there existing definitions, lists, cheat sheets for such patterns? Are there any provisions (mainly in PHPUnit, as that's the framework I'm working in) to automate such patterns? Is there any assistance - in the form of check lists, or software - to aid in writing complete tests?

  • unicode convertion problem

    Hai frnds i am bhoomi new to php,i am having having below problem in my coding please can you help anyone 1.first i want to open one word document which is having content and i wann to edit it 2.for that i am opening word document from the server and at that time its opening with garbage value(i thing its not converting to utf8 format) 3.wen i delete that garbage value and insert something from textarea to that file it is going to insert and next time onwords its its getting open properly. 4.actually i wann that doc file should open with english words wats there in that doc instead of garbage value..first time opening only its giving problem. i am using below code for that please do the needful $filename = 'test.doc'; if(isset($_REQUEST['Submit'])){ $somecontent = stripslashes($_POST['somecontent']); // Let's make sure the file exists and is writable first. if (is_writable($filename)) { // In our example we're opening $filename in append mode. // The file pointer is at the bottom of the file hence // that's where $somecontent will go when we fwrite() it. if (!$handle = fopen($filename, 'w')) { echo "Cannot open file ($filename)"; exit; } // Write $somecontent to our opened file. if (fwrite($handle, $somecontent) === FALSE) { echo "Cannot write to file ($filename)"; exit; } echo "Success, wrote ($somecontent) to file ($filename) - Continue - "; fclose($handle); } else { echo "The file $filename is not writable"; } } else{ // get contents of a file into a string $handle = fopen($filename, 'r'); $somecontent = fread($handle, filesize($filename)); ?

  • ID3DXAnimationController.RegisterAnimationSet - How exactly is this supposed to work?

    - by TrespassersW
    I have a mesh file that contains the skinned mesh that I want, and then a bunch of separate animation files that contain various AnimationSets. I'd like to have my program dynamically build the list of AnimationSets available to a mesh at run-time. I know I can combine these into one mesh file using MView, but that isn't practical for what I'm planning. I thought this would be pretty simple since ID3DXAnimationController.RegisterAnimationSet seems like it exists to do exactly this and the MView mesh viewer program can do this. But when I call RegisterAnimationSet using an animation from a different file, it fails with an unhelpful Invalid Call return value. Both the skinned mesh and the animation were exported from the same 3DS file, so I'm pretty certain that they are compatible. Here's my code: var anim : ID3DXAnimationSet; am : IDxAnimMesh; begin fAnim := ResMgr.AnimFetch('man01.x'); am := ResMgr.AnimFetch('a_rigtest.x'); DXCheck(am.Controller.GetAnimationSet(0,anim)); DXCheck(fAnim.Controller.RegisterAnimationSet(anim)); end; The file "man01.x" contains a default animation. And "a_rigtest.x" contains an animation exported from a different portion of the timeline fromt the same 3DS file. So it seems like they should be compatible. MView combines them with no trouble. Am I doing something wrong? Does anyone know how this is supposed to work? Or better yet, does anyone know where I could find the source code to MView? Any help would be appreciated.

  • Calculating collission for a moving circle, without overlapping the boundaries

    - by Robert Vella
    Let's say I have circle bouncing around inside a rectangular area. At some point this circle will collide with one of the surfaces of the rectangle and reflect back. The usual way I'd do this would be to let the circle overlap that boundary and then reflect the velocity vector. The fact that the circle actually overlaps the boundary isn't usually a problem, nor really noticeable at low velocity. At high velocity it becomes quite clear that the circle is doing something it shouldn't. What I'd like to do is to programmitically take reflection into account and place the circle at it's proper position before displaying it on the screen. This means that I have to calculate the point where it hits the boundary between it's current position and it's future position -- rather than calculating it's new position and then checking if it has hit the boundary. This is a little bit more complicated than the usual circle/rectangle collission problem. I have a vague idea of how I should do it -- basically create a bounding rectangle between the current position and the new position, which brings up a slew of problems of it's own (Since the rectangle is rotated according to the direction of the circle's velocity). However, I'm thinking that this is a common problem, and that a common solution already exists. Is there a common solution to this kind of problem? Perhaps some basic theories which I should look into?

  • Meteor: how to update DOM via Javascript without a page refresh?

    - by strack
    UPDATE: It looks like this script may be the catalyst I'm looking for. Will test it and answer/close this question if so. I'm sure I'll find the answer to this eventually, but I'm putting it out there now, in case someone else knows it right off... I am using RaphaelJS to manipulate the DOM (adds a bunch of SVG tags to an identified DIV), and I want to re-render those specific DOM parts, if there's an update to the MongoDB collection. As an example: -Let's say that I have a collection called PiePieces. -When the page is first rendered/ called, let's pretend that the number of pieces in the collection is 4. -I programmatically add a pie piece using console: PiePieces.insert({...}) -I want the page to update like it would for a standard handlebars binding situation, but the problem is, the new entry needs to go through the Raphael script, which performs direct DOM manipulation. So, the logic would go something like this: MongoDB collection update event - Client function call to manipulate DOM - DOM modified/ page updated without a refresh. I've tried implementing this by reading values from the DOM itself, and I can get the updated DOM, but the entire page refreshes and/or I have to manually refresh the page, OR the DOM tree isn't completed yet, and so it's blank until I refresh. Can you point me in the right direction, maybe with a small code snippet/example? (if something similar already exists, just tell me where and I'll go digging) Thanks in advance! (I am LOVING Meteor so far...)

  • Linear Interpolation. How to implement this algorithm in C ? (Python version is given)

    - by psihodelia
    There exists one very good linear interpolation method. It performs linear interpolation requiring at most one multiply per output sample. I found its description in a third edition of Understanding DSP by Lyons. This method involves a special hold buffer. Given a number of samples to be inserted between any two input samples, it produces output points using linear interpolation. Here, I have rewritten this algorithm using Python: temp1, temp2 = 0, 0 iL = 1.0 / L for i in x: hold = [i-temp1] * L temp1 = i for j in hold: temp2 += j y.append(temp2 *iL) where x contains input samples, L is a number of points to be inserted, y will contain output samples. My question is how to implement such algorithm in ANSI C in a most effective way, e.g. is it possible to avoid the second loop? NOTE: presented Python code is just to understand how this algorithm works. UPDATE: here is an example how it works in Python: x=[] y=[] hold=[] num_points=20 points_inbetween = 2 temp1,temp2=0,0 for i in range(num_points): x.append( sin(i*2.0*pi * 0.1) ) L = points_inbetween iL = 1.0/L for i in x: hold = [i-temp1] * L temp1 = i for j in hold: temp2 += j y.append(temp2 * iL) Let's say x=[.... 10, 20, 30 ....]. Then, if L=1, it will produce [... 10, 15, 20, 25, 30 ...]

  • How to view my Android app created database, via my android app?

    - by suufang
    I'm creating an application that collects users location (Cell broadcast location code) and saves that location with a name of users option, for example say my CB location code is 546034, now my app allows me to store that location code with a name of my choice say 'Home'. So, essentially my app has that following modules, To collect users CB location. To collect a custom name from user of that location. To store these values in a database. I've succeeded in doing all the above modules. I have a sub-module for my third module which has an option for user, of showing and deleting the database values, the screen shot looks as follows, Now, Users should be able to view and delete entries when he chooses the option 'View my database of locations' I've learned how to query my database values and I'm stuck with creating a list view and providing the delete option. My code for getting the database values and querying values goes as follows, submit.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { String locname = name.getText().toString(); if(locname.length()==0) { Toast.makeText(getBaseContext(), "Please enter the location name, for example 'Home'.", Toast.LENGTH_LONG).show(); } else { SQLiteDatabase cd = openOrCreateDatabase("mydata", MODE_WORLD_READABLE, null); cd.execSQL("CREATE TABLE IF NOT EXISTS MLITable (CblocationCode INT(10), CblocationName VARCHAR);"); cd.execSQL("INSERT INTO MLITable VALUES ('"+str+ "','"+locname+ "');"); cd.close(); Toast.makeText(getBaseContext(), "value successfully entered.", Toast.LENGTH_LONG).show(); } } }); viewdb.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { // here comes the code for viewing the database and deleting SQLiteDatabase db = openOrCreateDatabase("mydata", MODE_WORLD_READABLE, null); Cursor c = db.rawQuery("SELECT * FROM MLITble", null); db.close(); } }); I can see that I've read the table values, but I'm not able to create a display for those values. Help required. Thank you.

  • MySql stored procedure not found in PHP

  • C++ creating generic template function specialisations

    - by Fire Lancer
    I know how to specialise a template function, however what I want to do here is specialise a function for all types which have a given method, eg: template<typename T> void foo(){...} template<typename T, if_exists(T::bar)>void foo(){...}//always use this one if the method T::bar exists T::bar in my classes is static and has different return types. I tried doing this by having an empty base class ("class HasBar{};") for my classes to derive from and using boost::enable_if with boost::is_base_of on my "specialised" version. However the problem then is that for classes that do have bar, the compiler cant resolve which one to use :(. template<typename T> typename boost::enable_if<boost::is_base_of(HasBar, T>, void>::type f() {...} I know that I could use boost::disable_if on the "normal" version, however I do not control the normal version (its provided by a third party library and its expected for specialisations to be made, I just don't really want to make explicit specialisations for my 20 or so classes), nor do I have that much control over the code using these functions, just the classes implementing T::bar and the function that uses it. Is there some way to tell the compiler to "always use this version if possible no matter what" without altering the other versions?

  • Generating random thumbnails with PHP+FFMPEG

    - by MrGhost
    I am trying to generate thumbnails from movies using FFMPEG and the FFMPEG-PHP extension. My script works OK however takes 20 minutes just to generate 5-10 thumbnails! The script works by generating random numbers which are used as frame numbers later. All numbers generated are within the movies frame count. Can you work out why this script is taking 20 mins to finish? <?php //Dont' timeout set_time_limit(0); //Load the file (This can be any file - still takes ages) $mov = new ffmpeg_movie('1486460.mp4'); //Get the total frames within the movie $total_frames = $mov->getFrameCount(); //Loop 5 times to generate random frame times for ($i = 1; $i <= 5; ) { // Generate a number within 200 and the total number of frames. $frame = mt_rand(200,$total_frames); $getframe = $mov->getFrame($frame); // Check if the frame exists within the movie // If it does, place the frame number inside an array and break the current loop if($getframe){ $frames[$frame] = $getframe ; $i++; } } //For each frame found generate a thumbnail foreach ($frames as $key => $getframe) { $gd_image = $getframe->toGDImage(); imagejpeg($gd_image, "images/shot_".$key.'.jpeg'); imagedestroy($gd_image); echo $key.'<br/>'; } ?> The script SHOULD be generating frame numbers which are valid? Anything within START - END should be valid frame numbers? Yet the loop takes ages!

  • How do I determine when two moving points become visible to each other?

    - by Devin Jeanpierre
    Suppose I have two points, Point1 and Point2. At any given time, these points may be at different positions-- they are not necessarily static. Point1 is located at some position at time t, and its position is defined by the continuous functions x1(t) and y1(t) giving the x and y coordinates at time t. These functions are not differentiable, they are constructed piecewise from line segments. Point2 is the same, with x2(t) and y2(t), each function having the same properties. The obstacles that might prevent visibility are simple (and immobile) polygons. How can I find the boundary points for visibility? i.e. there are two kinds of boundaries: where the points become visible, and become invisible. For a become-visible boundary i, there exists some ?0, such that for any real number a, a ? (i-?, i) , Point1 and Point2 are not visible (i.e. the line segment that connects (x1(a), y1(a)) to (x2(a), y2(x)) crosses some obstacles). For b ? (i, i+?) they are visible. And it is the other way around for becomes-invisible. But can I find such a precise boundary, and if so, how?

  • How to provide warnings during validation in ASP.NET MVC?

    - by Alex
    Sometimes user input is not strictly invalid but can be considered problematic. For example: A user enters a long sentence in a single-line Name field. He probably should have used the Description field instead. A user enters a Name that is very similar to that of an existing entity. Perhaps he's inputting the same entity but didn't realize it already exists, or some concurrent user has just entered it. Some of these can easily be checked client-side, some require server-side checks. What's the best way, perhaps something similar to DataAnnotations validation, to provide warnings to the user in such cases? The key here is that the user has to be able to override the warning and still submit the form (or re-submit the form, depending on the implementation). The most viable solution that comes to mind is to create some attribute, similar to a CustomValidationAttribute, that may make an AJAX call and would display some warning text but doesn't affect the ModelState. The intended usage is this: [WarningOnFieldLength(MaxLength = 150)] [WarningOnPossibleDuplicate()] public string Name { get; set; } In the view: @Html.EditorFor(model => model.Name) @Html.WarningMessageFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) So, any ideas?

  • how to delete a line from file using awk filtered by some string

    - by embedded
    I have a file delimited by space. I need to write an awk command that receives a host name argument and it should replace the host name if it already defined in the file. It must be a full match not partially - if the file contains this host name: localhost searching for "ho" will fail and it will be added to the end of the file. another option is a delete: again awk receives host name argument and it should remove it from the file if exists. This is what I have so far: (It needs some enhancements) if [ "$DELETE_FLAG" == "" ]; then # In this case the entry should be added or updated # if clause deals with updating an existing entry # END clause deals with adding a new entry awk -F"[ ]" "BEGIN { found = 0;} \ { \ if ($2 == $HOST_NAME) { \ print \"$IP_ADDRESS $HOST_NAME\"; \ found = 1; \ } else { \ print \$0; \ } \ } \ END { \ if (found == 0) { \ print \"$IP_ADDRESS $HOST_NAME\"; } \ } " \ /etc/hosts > /etc/temp_hosts else # Delete an existing entry awk -F'[ ]' '{if($2 != $HOST_NAME) { print $0} }' /etc/hosts > /etc/temp_hosts fi Thanks

  • How to re-enable the idle timer in ios once it has been disabled (to allow the display to sleep again)?

    - by lindon fox
    I have figured out how to stop an iOS device from going to sleep (see below), but I am having troubles undoing that setting. According to the Apple Documentation, it should just be changing the value of the idleTimerDisabled property. But when I test this, it does not work. This is how I am initially stopping the device from going to sleep: //need to switch off and on for it to work initially [UIApplication sharedApplication].idleTimerDisabled = NO; [UIApplication sharedApplication].idleTimerDisabled = YES; I would have thought that the following would do the trick: [UIApplication sharedApplication].idleTimerDisabled = NO; From the Apple Documentation: The default value of this property is NO. When most applications have no touches as user input for a short period, the system puts the device into a "sleep” state where the screen dims. This is done for the purposes of conserving power. However, applications that don't have user input except for the accelerometer—games, for instance—can, by setting this property to YES, disable the “idle timer” to avert system sleep. Important: You should set this property only if necessary and should be sure to reset it to NO when the need no longer exists. Most applications should let the system turn off the screen when the idle timer elapses. This includes audio applications. With appropriate use of Audio Session Services, playback and recording proceed uninterrupted when the screen turns off. The only applications that should disable the idle timer are mapping applications, games, or similar programs with sporadic user interaction. Has anyone come across this problem? I am testing on iOS6 and iOS5. Thanks in advance.
