  • Garbage Collection leak? Scripting Bridge leak?

    - by Y.Vera
    Hello everyone! I'm always really picky about memory leaks and I cannot understand why my garbage collected application leaks. My code is entirely memory-managed and it runs great without garbage collection, not a single leak. However, as soon as I turn on garbage collection it leaks! Just to prove a point, why does this leak in a garbage collected app? (place this dummy code at applicationDidFinishLaunching:) NSOpenPanel *panel = [NSOpenPanel openPanel]; [panel beginSheetModalForWindow:window completionHandler:^(NSInteger result) {NSBeep();}]; Also, is there a way to prevent leaks in apps (garbage collected or otherwise) that use Scripting Bridge? it seems as if they all leak, even the sample ones in xcode. Thanks everybody!

  • Mixing garbage collected framework with normal code

    - by shw
    I know my way around Objective-C and I have experience with garbage collection from .NET, although I never used it in objective-c. I write my code without using it. Now I'm thinkig about using one of the frameworks (Blocks) which is available as GC-only. My question is - can I still use the framework without any changes to my current non-GC code and without using GC myself?

  • How can I check the content of the arrays? Parsing XML file with ObjectiveC

    - by skiria
    I have 3 classes- video { nameVideo, id, description, user... } topic {nameTopic, topicID, NSMutableArray videos; } category {nameCategory, categoryID, NSMUtableArray topics} And then in my app delegate I defined- NSMutableArray categories; I parse an XML file with this code. I try the arrays hierachy, and i think that i don't add any object on the arrays. How can I check it? What's wrong? (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { if([elementName isEqualToString:@"Videos"]) { //Initialize the array. appDelegate.categories = [[NSMutableArray alloc] init]; } else if ([elementName isEqualToString:@"Category"]) { aCategory = [[Category alloc] init]; aCategory.categoryID = [[attributeDict objectForKey:@"id"] integerValue]; NSLog(@"Reading id category value: %i", aCategory.categoryID); } else if ([elementName isEqualToString:@"Topic"]) { aTopic = [[Topic alloc] init]; aTopic.topicID = [[attributeDict objectForKey:@"id"] integerValue]; NSLog(@"Reading id topic value: %i", aTopic.topicID); } else if ([elementName isEqualToString:@"video"]) { aVideo = [[Video alloc] init]; aVideo.videoID = [[attributeDict objectForKey:@"id"] integerValue]; aVideo.nameTopic = currentNameTopic; aVideo.nameCategory = currentNameCategory; NSLog(@"Reading id video value: %i", aVideo.videoID); } NSLog(@"Processing Element: %@", elementName); } (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else [currentElementValue appendString:string]; NSLog(@"Processing Value: %@", currentElementValue); } (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if([elementName isEqualToString:@"Videos"]) return; if ([elementName isEqualToString:@"Category"]) { [appDelegate.categories addObject:aCategory]; [aCategory release]; aCategory = nil; } if ([elementName isEqualToString:@"Topic"]) { [aCategory.topics addObject:aTopic]; //NSLog(@"contador: %i", [aCategory.topics count]); //NSLog(@"contador: %@", aTopic.nameTopic); [aTopic release]; aTopic = nil; } if ([elementName isEqualToString:@"video"]) { [aTopic.videos addObject:aVideo]; NSLog(@"count number videos: %i", [aTopic.videos count]); -- always 0 NSLog(@"NOM CATEGORIA VIDEO: %@", aVideo.urlVideo); -- OK [aVideo release]; aVideo = nil; } if ([elementName isEqualToString:@"nameCategory"]) { //[aCategory setValue:currentElementValue forKey:elementName]; aCategory.nameCategory = currentElementValue; currentNameCategory = currentElementValue; } if ([elementName isEqualToString:@"nameTopic"]) { aTopic.nameTopic = currentElementValue; currentNameTopic = currentElementValue; } else [aVideo setValue:currentElementValue forKey:elementName]; [currentElementValue release]; currentElementValue = nil; }

  • asynchronous method executing

    - by alexeyndru
    I have a delegate method with the following tasks: get something from the internet (ex: some image from a web site); process that image in a certain way; display the result in a subview ; getting the image takes some time, depending on the network's speed so the result of its processing is displayed in the subview after that little while. my problem: during the time between getting the image and showing the result the device looks unresponsive. any attempt to put some spinner, or any other method which is called inside this main procedure has no effect until the result is processed. how should I change this behaviour? I would like to put a big spinner during that waiting time. thank you.

  • CoreData NSFetchedResultsController Empty Section Display

    - by user280390
    Hello I would like to show a fixed number of sections in a table view with a Fetched Results Controller as the data source. If you image the contacts app where sections organised by the alphabet, it will not have a header for B if there are no contacts in that section, so the section headers you see are A then C. I would like to display a section header in my table (for B), but without any rows. an empty section in effect. Can NSFetchedResultsController do this for me?

  • Is there a high-level gestures library for iPhone development?

    - by n8gray
    The iPhone platform has a number of common gesture idioms. For example, there are taps, pinches, and swipes, each with varying number of fingers. But when you're developing an app, it's up to you to implement these things based on low-level information about the number and locations of touches. It seems like this is a prime candidate for a library. You would register a delegate, set some parameters like multi-tap interval and swipe threshold, and get calls like swipeStarted/Ended, pinchStarted/Ended, multiTap, etc. Does such a library exist?

  • Updating Label on previously loaded view?

    - by fuzzygoat
    I am working on a simple app tab-bar based application that has two views. The first is the main application and the second is a simple instruction screen. What I am trying to do is create a update a label on that second screen as things change in the main app. Because the second screen is only simple with one label and some text I am not unloading it once its loaded. After the first viewDidLoad I can update the label just fine, but after that is there a way to catch successive view switches from the tab-bar menu so I can update the label? many thanks gary

  • Passing values from UIButton to an UIActionSheet

    - by Michael
    I'm trying to send an ActionSheet a variable from a button. I can't use the tag property because its being used for something else. I've declared myIndexRow as an instance variable and have: NSInteger myIndexRow = indexPath.row; [deleteButton addTarget:self action:@selector(showDeleteSheet:) forControlEvents:UIControlEventTouchUpInside]; deleteButton.myIndexRow = myIndexRow; but I'm getting the 'Request for member 'myRow' is something not a structure or union' There is something obvious I am missing here.

  • Filter entire NSDictionaries out of NSArray based on multiple keys

    - by user270475
    Hi, I have an NSArray of NSDictionary objects which I would like to be able to return a new array of NSDictionaries from, where every NSDictionary has "Area == North" (for example). The closest example I have found so far is http://stackoverflow.com/questions/958622/using-nspredicate-to-filter-an-nsarray-based-on-nsdictionary-keys but this just returns the unique values for a given key, not the dictionary that has that key. Is there any way to perform a similar operation, and to return the entire dictionary?

  • NSOperations or NSThread for bursts of smaller tasks that continuously cancel each other?

    - by RickiG
    Hi I would like to see if I can make a "search as you type" implementation, against a web service, that is optimized enough for it to run on an iPhone. The idea is that the user starts typing a word; "Foo", after each new letter I wait XXX ms. to see if they type another letter, if they don't, I call the web service using the word as a parameter. The web service call and the subsequent parsing of the result I would like to move to a different thread. I have written a simple SearchWebService class, it has only one public method: - (void) searchFor:(NSString*) str; This method tests if a search is already in progress (the user has had a XXX ms. delay in their typing) and subsequently stops that search and starts a new one. When a result is ready a delegate method is called: - (NSArray*) resultsReady; I can't figure out how to get this functionality 'threaded'. If I keep spawning new threads each time a user has a XXX ms. delay in the typing I end up in a bad spot with many threads, especially because I don't need any other search, but the last one. Instead of spawning threads continuously, I have tried keeping one thread running in the background all the time by: - (void) keepRunning { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; SearchWebService *searchObj = [[SearchWebService alloc] init]; [[NSRunLoop currentRunLoop] run]; //keeps it alive [searchObj release]; [pool release]; } But I can't figure out how to access the "searchFor" method in the "searchObj" object, so the above code works and keeps running. I just can't message the searchObj or retrieve the resultReady objects? Hope someone could point me in the right direction, threading is giving me grief:) Thank you.

  • How do I get Spotlight attributes to display in the get info window?

    - by Alexander Rauchfuss
    I have created a spotlight importer for comic files. The attributes are successfully imported and searchable. The one thing that remains is getting the attributes to display in a file's get info window. It seems that this should be a simple matter of editing the schema.xml file so the attributes are nested inside displayattrs tags. Unfortunately this does not seem to be working. I simplified the plugin for testing. The following are all of the important files. schema.xml <types> <type name="cx.c3.cbz-archive"> <allattrs> kMDItemTitle kMDItemAuthors </allattrs> <displayattrs> kMDItemTitle kMDItemAuthors </displayattrs> </type> <type name="cx.c3.cbr-archive"> <allattrs> kMDItemTitle kMDItemAuthors </allattrs> <displayattrs> kMDItemTitle kMDItemAuthors </displayattrs> </type> GetMetadataForFile.m Boolean GetMetadataForFile(void* thisInterface, CFMutableDictionaryRef attributes, CFStringRef contentTypeUTI, CFStringRef pathToFile) { NSAutoreleasePool * pool = [NSAutoreleasePool new]; NSString * file = (NSString *)pathToFile; NSArray * authors = [[UKXattrMetadataStore stringForKey: @"com_opencomics_authors" atPath: file traverseLink: NO] componentsSeparatedByString: @","]; [(NSMutableDictionary *)attributes setObject: authors forKey: (id)kMDItemAuthors]; NSString * title = [UKXattrMetadataStore stringForKey: @"com_opencomics_title" atPath: file traverseLink: NO]; [(NSMutableDictionary *)attributes setObject: title forKey: (id)kMDItemTitle]; [pool release]; return true; }

  • How to change format of date/time?

    - by 4thSpace
    I have this date and time format: 2010-05-19 07:53:30 and would like to change it to: Wednesday @ 7:53PM 5/19/2010 I'm doing this, which gets the current format: NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss"; but when I change the format, I end up with a null. For example: formatter.dateFormat = @"hh:mm tt MM-dd-yyyy"; date = [formatter stringFromDate:formattedDate]; date will be null. I want to put the end result into an NSString. It would be nice if time and date could come out as separate properties so I can arrange them however I like. Any ideas on how I can change the formatting?

  • NSTableView with columns bound to different NSArrayControllers

    - by Vyacheslav Karpukhin
    i have NSTableView and two columns in it: NSTableColumn *column = [[[NSTableColumn alloc] initWithIdentifier:@"custId"] autorelease]; [column bind:@"value" toObject:arrC2 withKeyPath:@"arrangedObjects.custId" options:nil]; [table addTableColumn:column]; column = [[[NSTableColumn alloc] initWithIdentifier:@"totalGrams"] autorelease]; [column bind:@"value" toObject:valuationArrC withKeyPath:@"arrangedObjects.totalGrams_double" options:nil]; [table addTableColumn:column]; as you can see, columns bound to different NSArrayControllers. first column shows correct values, but second just shows "(" symbol. but if i swap columns like this: NSTableColumn *column = [[[NSTableColumn alloc] initWithIdentifier:@"totalGrams"] autorelease]; [column bind:@"value" toObject:valuationArrC withKeyPath:@"arrangedObjects.totalGrams_double" options:nil]; [table addTableColumn:column]; column = [[[NSTableColumn alloc] initWithIdentifier:@"custId"] autorelease]; [column bind:@"value" toObject:arrC2 withKeyPath:@"arrangedObjects.custId" options:nil]; [table addTableColumn:column]; then i see values of first column (which was second in the first example) and again "(" in the second column. i don't understand that behaviour. how can i bound two array controllers to one table?
