  • deallocated memory in tableview: message sent to deallocated instance

    - by Kirn
    I tried looking up other issues but couldn't find anything to match so here goes: I'm trying to display text in the table view so I use this bit of code: // StockData is an object I created and it pulls information from Yahoo APIs based on // a stock ticker stored in NSString *heading NSArray* tickerValues = [heading componentsSeparatedByString:@" "]; StockData *chosenStock = [[StockData alloc] initWithContents:[tickerValues objectAtIndex:0]]; [chosenStock getData]; // Set up the cell... NSDictionary *tempDict = [chosenStock values]; NSArray *tempArr = [tempDict allValues]; cell.textLabel.text = [tempArr objectAtIndex:indexPath.row]; return cell; This is all under cellForRowAtIndexPath When I try to release the chosenStock object though I get this error: [CFDictionary release]: message sent to deallocated instance 0x434d3d0 Ive tried using NSZombieEnabled and Build and Analyze to detect problems but no luck thus far. Ive even gone so far as to comment bits and pieces of the code with NSLog but no luck. I'll post the code for StockData below this. As far as I can figure something is getting deallocated before I do the release but I'm not sure how. The only place I've got release in my code is under dealloc method call. Here's the StockData code: // StockData contains all stock information pulled in through Yahoo! to be displayed @implementation StockData @synthesize ticker, values; - (id) initWithContents: (NSString *)newName { if(self = [super init]){ ticker = newName; } return self; } - (void) getData { NSURL *url = [NSURL URLWithString: [NSString stringWithFormat:@"http://download.finance.yahoo.com/d/quotes.csv?s=%@&f=%@&e=.csv", ticker, @"chgvj1"]]; NSError *error; NSURLResponse *response; NSURLRequest *request = [NSURLRequest requestWithURL:url]; NSData *stockData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; if(stockData) { NSString *tempStr = [[NSString alloc] initWithData:stockData encoding:NSASCIIStringEncoding]; NSArray *receivedValuesArr = [tempStr componentsSeparatedByString:@","]; [tempStr release]; values = [NSDictionary dictionaryWithObjects:receivedValuesArr forKeys:[@"change, high, low, volume, market" componentsSeparatedByString:@", "]]; } else { NSLog(@"Connection failed: %@", error); } } - (void)dealloc { [ticker release]; [values release]; [super dealloc]; NSLog(@"Release took place fine"); } @end

  • how could I store data within a GUID

    - by Mark
    I have an application that I want to represent a users session (just small pieces of data here and there) within a GUID. Its a 16 HEX characters (so 16^16 possible values) string and I want to 'encode' some data within that GUID. How can I achieve this? I am really after any ideas and implementations here, Ive not yet decided on the best mechanism for it yet. I would also like encryption to be involved if possible... Thanks a lot Mark

  • Unit Testing - Am I doing it right?

    - by baron
    Hi everyone, Basically I have been programing for a little while and after finishing my last project can fully understand how much easier it would have been if I'd have done TDD. I guess I'm still not doing it strictly as I am still writing code then writing a test for it, I don't quite get how the test becomes before the code if you don't know what structures and how your storing data etc... but anyway... Kind of hard to explain but basically lets say for example I have a Fruit objects with properties like id, color and cost. (All stored in textfile ignore completely any database logic etc) FruitID FruitName FruitColor FruitCost 1 Apple Red 1.2 2 Apple Green 1.4 3 Apple HalfHalf 1.5 This is all just for example. But lets say I have this is a collection of Fruit (it's a List<Fruit>) objects in this structure. And my logic will say to reorder the fruitids in the collection if a fruit is deleted (this is just how the solution needs to be). E.g. if 1 is deleted, object 2 takes fruit id 1, object 3 takes fruit id2. Now I want to test the code ive written which does the reordering, etc. How can I set this up to do the test? Here is where I've got so far. Basically I have fruitManager class with all the methods, like deletefruit, etc. It has the list usually but Ive changed hte method to test it so that it accepts a list, and the info on the fruit to delete, then returns the list. Unit-testing wise: Am I basically doing this the right way, or have I got the wrong idea? and then I test deleting different valued objects / datasets to ensure method is working properly. [Test] public void DeleteFruit() { var fruitList = CreateFruitList(); var fm = new FruitManager(); var resultList = fm.DeleteFruitTest("Apple", 2, fruitList); //Assert that fruitobject with x properties is not in list ? how } private static List<Fruit> CreateFruitList() { //Build test data var f01 = new Fruit {Name = "Apple",Id = 1, etc...}; var f02 = new Fruit {Name = "Apple",Id = 2, etc...}; var f03 = new Fruit {Name = "Apple",Id = 3, etc...}; var fruitList = new List<Fruit> {f01, f02, f03}; return fruitList; }

    - by JimDel
    I'm looking for a way to create a vCards from Outlook Contacts. Ive seen plenty of examples of how to do the reverse, but that's not what i want. I believe it will involve either the OpenSharedItem method or the OpenSharedFolder method but I havent seen any examples of how to implement this. Does anyone know of where I might find a sample or two? My end goal is to output all my Contacts as vCards to a folder.

    Is there a way to resize a control, a JTextfield for example, at runtime in java? I want my textfield to have the resize cursors (just like when you point your cursor on the corner of a window) and will be able to resize on runtime. Ive read on the internet that vb6 and C# have those capabilities, is there anything for java? A sample code or a link to a good tutorial will be very much appreciated. Thank you.
