  • iphone: memory problems after refactor

    - by agilpwc
    I had a NIB with several view controllers in it. I modified the code and used Interface Builder decomose interface to get all the view controllers in their own Nib. But now with empty core data database, I'm getting "message sent to deallocated instance" errors. Here is the code flow: From the RootViewController this is called: if (self.dogController == nil) { DogViewController *controller = [[DogViewController alloc] initWithNibName:@"DogViewController" bundle:nil]; self.dogController = controller; [controller release]; } self.dogController.managedObjectContext = self.managedObjectContext; [self.navigationController pushViewController:self.dogController animated:YES]; Then in a dogController a button is pressed to insert a new object and the following code is excuted and the error hits on the save, according to the trace NSManagedObjectContext *context = [self.fetchedResultsController managedObjectContext]; NSEntityDescription *entity = [[self.fetchedResultsController fetchRequest] entity]; NSManagedObject *newManagedObject = [NSEntityDescription insertNewObjectForEntityForName:[entity name] inManagedObjectContext:context]; // If appropriate, configure the new managed object. [newManagedObject setValue:[NSDate date] forKey:@"birthDate"]; [newManagedObject setValue:@"-" forKey:@"callName"]; // Save the context. NSError *error = nil; if (![context save:&error]) { Then the error produced in the console is * -[JudgeViewController numberOfSectionsInTableView:]: message sent to deallocated instance 0x598e580 I'm racking my brain for hours and I can't figure out where my minor changes made something messed up. Any ideas?

  • iphone detailtext in UITableView question

    - by Rob
    So, I am able to create an array that populates the fields of the Table, but am having troubles creating the subtext that appears below the main fields. I currently have: - (void)viewDidLoad { [super viewDidLoad]; listOfForms = [[NSMutableArray alloc] init]; [listOfForms addObject:@"First Form"]; } and then: NSString *cellValue = [listOfDAForms objectAtIndex:indexPath.row]; cell.textLabel.text = cellValue; in the cellForRowAtIndexPath portion. Why can't I add: listOfNames = [[NSMutableArray alloc] init]; [listOfNames addObject:@"Named Form"]; and NSString *cellSubscript = [listOfNames objectAtIndex:indexPath.row]; cell.detailTextLabel.text = cellSubscript; in order to make the little subview work? What am I doing wrong?

  • Instance of method leaking, iPhone

    - by Wolfert
    The following method shows up as leaking while performing a memory-leaks test with Instruments: - (NSDictionary*) initSigTrkLstWithNiv:(int)pm_SigTrkNiv SigTrkSig:(int)pm_SigTrkSig SigResIdt:(int)pm_SigResIdt SigResVal:(int)pm_SigResVal { NSArray *objectArray; NSArray *keyArray; if (self = [super init]) { self.SigTrkNiv = [NSNumber numberWithInt:pm_SigTrkNiv]; self.SigTrkSig = [NSNumber numberWithInt:pm_SigTrkSig]; self.SigResIdt = [NSNumber numberWithInt:pm_SigResIdt]; self.SigResVal = [NSNumber numberWithInt:pm_SigResVal]; objectArray = [NSArray arrayWithObjects:SigTrkNiv,SigTrkSig,SigResIdt,SigResVal, nil]; keyArray = [NSArray arrayWithObjects:@"SigTrkNiv", @"SigTrkSig", @"SigResIdt", @"SigResVal", nil]; self = [NSDictionary dictionaryWithObjects:objectArray forKeys:keyArray]; } return self; } code that invokes the instance: NSDictionary *lv_SigTrkLst = [[SigTrkLst alloc]initSigTrkLstWithNiv:[[tempDict objectForKey:@"SigTrkNiv"] intValue] SigTrkSig:[[tempDict objectForKey:@"SigTrkSig"] intValue] SigResIdt:[[tempDict objectForKey:@"SigResIdt"] intValue] SigResVal:[[tempDict objectForKey:@"SigResVal"] intValue]]; [[QBDataContainer sharedDataContainer].SigTrkLstArray addObject:lv_SigTrkLst]; [lv_SigTrkLst release]; Instruments informs that 'SigTrkLst' is leaking. Even though I have released the instance? (I know that adding it to the array increments the retainCount by 1 but releasing it twice removes it from the array?)

  • One iPhone, two developer machines

    - by willcodejavaforfood
    Hi all, I switch between my iMac and MacBook when working on my apps. I've always used my iMac to test the apps on the actual device, but I would like to be able to do this from both computers. I cannot seem to use the profile on my MacBook as it does not have the correct Certificate Signing Request in the KeyChain. Is there a way to copy these between machines and KeyChains? :)

  • Change backgroundcolor for UIButton IPhone

    I have a problem. I use a Button as a BarButtonItem. It works fine so far, but my backgroundcolor works only if I click on my button. How can I make it so that my backgroundcolor will be set every time ? UIButton *redEmergencyButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain]; redEmergencyButton.frame = CGRectMake(100, 100, 100, 50); redEmergencyButton.backgroundColor = [UIColor colorWithRed:0.8 green:0.898039215686274509803 blue:1.0 alpha:1.0]; [redEmergencyButton setTitle:@"Emergency" forState:UIControlStateNormal]; [redEmergencyButton addTarget:self action:@selector(doEmergency) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem *rButton = [[UIBarButtonItem alloc] initWithCustomView:redEmergencyButton];

  • Google App Engine: Update model definitons?

    - by Rosarch
    I recently updated one of my models by adding a db.ListProperty(): class DependencyArcTail(db.Model): courses = db.ListProperty(db.Key) ''' newly added ''' forwardLinks = db.ListProperty(db.Key) However, I can't seem to get this to be reflected in the SDK dashboard. I cleared the datastore and reloaded it. Then I ran the procedures that create the DependencyArcTail objects. However, forwardLinks still doesn't show up as an attribute in the SDK dashboard. What's happening?

  • getClientRects javascript method supported on iPhone?

    - by genericdan
    Trying to find the top-most visible element in a UIWebView. I am using a JS method to do this, which works great in Safari, but never executes past the getClientRects method when executed from a UIWebView. The elements I'm interested are all of class="h". Here's the javascript which is called from [webView stringByEvaluatingJavaScriptFromString:@"findTopElement()"]; Javascript: function findTopElement() { var pars = document.getElementsByClassName("h"); alert("findingTopElement: num pars:" + pars.length); for (var i = 0; i < pars.length; i++) { var para = pars[i]; alert("checking par " + para.id); var rects = para.getClientRects(); alert("checking rects " + rects.length); for (var j = 0; j < rects.length; j++) { var r = rects[j]; if (r.top > 0 && r.bottom > 0) { alert("success: " + para.id); return para.id; } } } return -1; } Is it possible element getClientRects function is not supported in a UIWebView?

  • Iphone -- maintaining a list of strings and a corresponding typedef enum

    - by William Jockusch
    Suppose I have the following: typedef enum functionType {ln, sin, sqrt} functionType; NSArray *functions = [NSArray arrayWithObjects: @"ln", @"sin", @"sqrt", nil]; Suppose further that *functions will not change at runtime. Question -- is there any way to set up a single structure which updates both of these? So that I only have to keep track of one list, instead of two. To explain what is going on -- the idea is that string input from the user will be stored in a variable of type functionType. Later on, I will have code like this: double valueOfFunction: (functionType) function withInput: (double) input switch (function) { case ln: return ln(input); case sin: return sin(input); case sqrt: return sqrt(input); //etc . . . could grow to include a lot of functions. } And valueOfFunction needs to be fast. So I don't want to be doing string comparisons there.
