  • Memory Management iOS dev app doesn't work after a few detail items

    - by user1434846
    I am working on a project with a tableView controller and the detail views contains CMMotionManager.When i open 5 or 6 detailViews all goes well,but after a while the app goes slow and finally crashes.On instruments the only leak is on main.m , also i must say that I'm using ARC and i can't dealloc or realese the instances. Here is the code: First the table view: - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. self.title = @"Movement";//Master View Controller title bar UIImage *image = [UIImage imageNamed:@"jg_navibar.png"]; [self.navigationController.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault]; //Init the array with data bodypartsMutableArray = [NSMutableArray arrayWithCapacity:26]; BodypartData *part1 = [[BodypartData alloc] init]; part1.bodypartname = @"Shoulder"; part1.movementname = @"Flexion"; part1.fullimageStartingPosition=[UIImage imageNamed:@"2_shoulder_flexion_end_position.jpg"]; part1.fullimageEndedPosition=[UIImage imageNamed:@"2_shoulder_flexion_end_position.jpg"]; part1.thumbimage=[UIImage imageNamed:@"1_shoulder_flexion_landmarks_thumb.jpg"]; [bodypartsMutableArray addObject:part1]; ......... } then the cell: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyBasicCell"]; BodypartData *part = [self.bodypartsMutableArray objectAtIndex:indexPath.row]; cell.textLabel.text =[NSString stringWithFormat:part.movementname]; cell.detailTextLabel.text =[NSString stringWithFormat:part.bodypartname]; cell.imageView.image =part.thumbimage; return cell; } and the the detailViewdid load: - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. // Init motionManager object and set the Update Interval _motionManager = [[CMMotionManager alloc]init]; _motionManager.deviceMotionUpdateInterval=1/60; //60 Hz [_motionManager startGyroUpdates]; if (_motionManager.gyroAvailable) { _motionManager.gyroUpdateInterval = 1.0/60.0; [_motionManager startDeviceMotionUpdatesToQueue:[NSOperationQueue currentQueue] withHandler: ^(CMDeviceMotion *motion, NSError *error) { CMAttitude *attitude = motion.attitude; //Calculation with rotationMatrix m11 = [NSString stringWithFormat:@"%.02f", attitude.rotationMatrix.m11]; m12 = [NSString stringWithFormat:@"%.02f", attitude.rotationMatrix.m12]; m13 = [NSString stringWithFormat:@"%.02f", attitude.rotationMatrix.m13]; ......... }

  • Profilers for ASP.Net Web Applications?

    - by Earlz
    I was recently wanting to do some profiling on an ASP.Net project and was surprised to see that Visual Studio (at least seems to be) lacking a profiler. So my question is what profiler do you use for ASP.Net? Are there any decent ones out there that are free? I've seen a few general .Net profilers but have yet to see one that can be used with ASP.Net..

  • Using KnockoutJS 2.2.0 & jQuery 1.8.2 remove all bindings from all children of #someDiv

    - by Nukeface
    I'm wanting to delete All bindings (ko.cleanNode) from all child elements of a certain div. Must be a noobie question but I can't figure out how to use jQuery to loop through all childre, grand-children, great-grand-children, etc. whilst having KnockoutJS remove the bindings of all the DOM elements. I do NOT want to remove the elements from the DOM. This is a single page application, therefore the elements are pre-loaded as embedded resources and don't get resend to a client if they were to visit the page again. If a client revisits that part of the application I'll have a function rebind the necessary elements, which currently works fine. Current setup: <html> <head> //loading all resources </head> <body> //load first element using some obscure setup <div id="firsPage" data-role="page"> <div data-role="header">@Global.header</div> <div data-role="fieldcontain"> <label for="firstInput" /> <input id="firstInput some other stuff /> </div> <div data-role="datebox <!-- some settings --> > //creates table using jQuery mobile (lots of (great-)(grand-)children) </div> <div data-role="fieldcontain"> <div id="secondInput"> <div class="checklist"> <ul> <li /> <li /> </ul> </div> </div> </div> </div> //Here the whole thing starts again <div id="secondPage" data-role="page"> <!-- repeat above innerHTML in your mind ;) --> </div> //And here again! and again... </body> The problem I'm having is that bindings of the children don't seem to get "cleaned up" when i use ko.cleanNode($('#firstPage')[0]); Or when I get the Element into a variable and then format it to ko.cleanNode($element). Is there a way to do this? Been staring at it for a good few hours now, so probably overlooking a way too obvious way of doing it... Thanks!

  • How does msbuild decide whether it needs to rebuild a C# library or not?

    - by Peter Mounce
    Per subject, how does msbuild decide whether it needs to rebuild a library (ie, invoke csc), or not, when it is run against a C# project file? I imagine (but want to confirm): If there's no output directory, rebuild (duh :) ) If a C# file has changed, rebuild If an included file marked copy-always has changed, rebuild or is it smart enough to not rebuild, but just copy the file to the existing output? If an included file marked copy-if-newer has changed, rebuild same question as above

  • JSF action, value and binding catalog generator

    - by BBSnowman
    I am looking for a simple tool that generates a catalog of all used action methods, values and bindings. I'm working on a big JSF/RichFaces project and I have lost the overview of the used links to the beans. Therefore I need a tool (would be nice if it is a Eclipse plugin) that generates a simple list of all used EL expressions. Is there something out there?

  • Move your Working Copy

    - by coffeeaddict
    I tried to find out how to move my working copy. I know SVN move can be used to move files and folders inside your working copy but what about the working copy itself? I want to move it because I created a branch in a folder location that's different from my branch and had updated therefore all my .NET project references. So when I go to merge back to the mainline trunk I get a bunch of tree conflicts.

  • What DirectShow Interface to use for capturing to Stream instead of creating actual file?

    - by jhorton
    I've got a DirectShow project where I want to capture and stream to a webserver. I have seen how to capture and create a file, but I'm looking for ideas on how to capture into something like a MemoryStream to transport through a NetworkStream. I'm also using the library DirectShowLib for the ability to write in C# if that makes any difference. Of if there is a sample that I overlooked in the SDK I would greatly appreciate the direction. Thanks in advance.

  • Makefile - How to save the .o one directory up?

    - by nunos
    Imagine the following folder structure: project src code.c makefile bin How can I compile code.c to code.o and directly put it inside bin? I know I could compile it to code.o under src and the do "mv code.o ../bin" but that would yield an error if there were compile errors, right? Even if it works that way, is there a better way to do it? Thanks.

  • What is the most annoying ignorance you've had in programming?

    - by someone
    What was an annoying programming situation you had that a little bit of knowledge could've solved? That after you struggled with something tedious/annoying/frustrating, you learned one small thing and said "oh, I could've done that?!"? My example - I once suffered through an entire tedious semester of HTML in Notepad... only to discover Notepad++ (and DreamWeaver, IDEs, etc.) a couple of days after submitting the final project.

    - by renulren
    Hi all, I am working on a project that pulls data out of an xml files and also uses a tree-grid combination in order to display the data. For example depending on the selected treeview node, the datagridview will display only the records related to that node. What do you think it would be the appropriate approach in dealing with this? Thanks!

  • iPhone development on Windows

    - by AngryHacker
    Is there a way to develop iPhone applications on Windows? I really don't want to get yet another machine. There is a project on http://code.google.com/p/winchain/wiki/HowToUse that seemed to work with iPhone 1.0, but had limited success with iPhone 2.0, plus it requires all the cygwin insanity. Is there anything else, or do I have to buy a mac?

  • Can I set svn properties through ankhsvn?

    - by grungean
    I am using ankhsvn with VS2008. I am using a free repo hosting on the web. I am not using a svn client for this repo, but managing everything with ankhsvn (including adding solution file and project files to the new repo). I want to add the svn:needs-lock preperty to these files. I wonder if I can do this task using ankhsvn, or if I need to get another svn client for this purpose.
