  • using KVO to update an NSTableView filtered by an NSPredicate

    - by KingRufus
    My UI is not updating when I expect it to. The application displays "projects" using a view similar to iTunes -- a source list on the left lets you filter a list (NSTableView) on the right. My filters update properly when they are examining any simple field (like name, a string), but not for arrays (like tags). I'm removing a tag from one of my objects (from an NSMutableArray field called "tags") and I expect it to disappear from the list because it no longer matches the predicate that is bound to my table's NSArrayController. ProjectBrowser.mm: self.filter = NSPredicate* srcPredicate = [NSPredicate predicateWithFormat:@"%@ IN %K", selectedTag, @"tags"]; Project.mm: [self willChangeValueForKey:@"tags"]; [tags removeAllObjects]; [self didChangeValueForKey:@"tags"]; I've also tried this, but the result is the same: [[self mutableArrayValueForKey:@"tags"] removeAllObjects]; Interface Builder setup: a ProjectBrowser object is the XIB's File Owner an NSArrayController (Project Controller) has its Content Array bound to "File's Owner".projects Project Controller's filter predicate is bound to "File's Owner".filter NSTableView's column is bound to "Project Controller".name

  • Adding a searchbar to display array items on a tableview?

    - by skiria
    I want to build an app that shows a empty tableview. Then users can write a text on a searchbar and when they click on Search button the tableview will be written with array items founded. I've see this tutorial: link text, but I only need to search when user click SearchButton. How can I do this? What methods do i have to use? I've tried with this method, but it doesn't works. - (void) searchBarSearchButtonClicked:(UISearchBar *)theSearchBar { NSInteger nVideos = [appDelegate.allVideos count]; NSLog(@"number of videos: %i", nVideos);

  • Removing object from NSMutableArray

    - by Ben Packard
    Just a small query... I stumbled across the following shortcut in setting up a for loop (shortcut compared to the textbook examples I have been using): for (Item *i in items){ ... } As opposed to the longer format: for (NSInteger i = 0; i < [items count]; i++){ ... } //think that's right If I'm using the shorter version, is there a way to remove the item currently being iterated over (ie 'i')? Or do I need to use the longer format?

  • How to configure a OCUnit test bundle for a framework?

    - by GuidoMB
    I've been developing a Mac OS X framework and I want to use OCUnit in my XCode 3.2.1 project. I've followed several tutorials on how to configure a OCUnit test bundle. The problem is that when I create a test case that uses a function that is defined in one of the framework's sources, I get a building error telling me that the symbol is not found. I made the test bundle dependent of my project's target as the tutorial said, but that doesn't seem to be problem. First I thought that I could solve this problem by dragging the framework's source files into the compile sources section within the Test bundle target, but then all the symbols referenced from that source file started to show up in the build errors, so that seems to not be a good solution/idea. How can I configure my unit test bundle so it builds properly?

  • Show image from url in uiimageview

    - by skiria
    I try to show a image in my iphone app but it doesn't show. I connect in IB and I check to show a local image, it workd good. I also check the url from image and it is ok. I use the next code: NSURL *imageURL = [NSURL URLWithString: aVideo.urlThumbnail]; NSData *imageData = [NSData dataWithContentsOfURL:imageURL]; UIImage *image = [UIImage imageWithData:imageData]; imageView.image = image; and //Video.h NSString *urlThumbnail; and this is my code on the view. - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [tableView reloadData]; } - (void)viewDidLoad { [super viewDidLoad]; NSURL *imageURL = [NSURL URLWithString: aVideo.urlThumbnail]; NSData *imageData = [NSData dataWithContentsOfURL:imageURL]; UIImage *image = [UIImage imageWithData:imageData]; imageView.image = image; }

  • Strange behaviour of NSScanner on simple whitespace removal

    - by Michael Waterfall
    I'm trying to replace all multiple whitespace in some text with a single space. This should be a very simple task, however for some reason it's returning a different result than expected. I've read the docs on the NSScanner and it seems like it's not working properly! NSScanner *scanner = [[NSScanner alloc] initWithString:@"This is a test of NSScanner !"]; NSMutableString *result = [[NSMutableString alloc] init]; NSString *temp; NSCharacterSet *whitespace = [NSCharacterSet whitespaceCharacterSet]; while (![scanner isAtEnd]) { // Scan upto and stop before any whitespace [scanner scanUpToCharactersFromSet:whitespace intoString:&temp]; // Add all non whotespace characters to string [result appendString:temp]; // Scan past all whitespace and replace with a single space if ([scanner scanCharactersFromSet:whitespace intoString:NULL]) { [result appendString:@" "]; } } But for some reason the result is @"ThisisatestofNSScanner!" instead of @"This is a test of NSScanner !". If you read through the comments and what each line should achieve it seems simple enough!? scanUpToCharactersFromSet should stop the scanner just as it encounters whitespace. scanCharactersFromSet should then progress the scanner past the whitespace up to the non-whitespace characters. And then the loop continues to the end. What am I missing or not understanding?

  • iOS: RestKit loadObject & send params

    - by Alon Amir
    using loadObjectAtResourcePath, on GET method, doesn't include my parameters on the requests. for example, i send: [RKObjectManager objectManagerWithBaseURL:@"http://something/ws"]; [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/res" delegate:self block:^(RKObjectLoader *loader) { NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys: @"val", @"param1", nil]; loader.params = [RKParams paramsWithDictionary:dict]; }]; the final url request doesn't include the "?param1=val" part - why is that?

  • noob iPhone "count" frustrations!?!?!

    - by codemonkey
    Okay, I know I must be doing something incredibly stupid here. Here's the sample code (which, when executed within a viewDidLoad block silently crashes... no error output to debug console). NSMutableArray *bs = [NSMutableArray arrayWithCapacity:10]; [bs addObject:[NSNumber numberWithInteger: 2]]; NSLog(@"%@", [bs count]); [bs release]; What am I missing? Oh... and in case anyone is wondering, this code is just me trying to figure out why I can't get the count of an NSMutableArray that actually matters somewhere else in the program.

  • Releasing Autoreleasepool crashes on iOS 4.0 (and only on 4.0)

    - by samsam
    Hi there. I'm wondering what could cause this. I have several methods in my code that i call using performSelectorInBackground. Within each of these methods i have an Autoreleasepool that is being alloced/initialized at the beginning and released at the end of the method. this perfectly works on iOS 3.1.3 / 3.2 / 4.2 / 4.2.1 but it fataly crashes on iOS 4.0 with a EXC_BAD_ACCESS Exception that happens after calling [myPool release]. After I noticed this strange behaviour I was thinking about rewriting portions of my code and to make my app "less parallel" in case that the client os is 4.0. After I did that, the next point where the app crashed was within the ReachabilityCallback-Method from Apples Reachability "Framework". well, now I'm not quite sure what to do. The things i do within my threaded methods is pretty simple xml parsing (no cocoa calls or stuff that would affect the UI). After each method finishes it posts a notification which the coordinating-thread listens to and once all the parallelized methods have finished, the coordinating thread calls viewcontrollers etc... I have absolutely no clue what could cause this weird behaviour. Especially because Apples Code fails as well. any help is greatly appreciated! thanks, sam

  • UISwitch text not showing on device

    - by iFloh
    Hi, I have a screen with several UISwitch controls. On my iPhone simulator this screen works correctly and The Switch text shows as On/Off. Different on my testing device (iPod Touch). Here the text seems to get lost and I only get "1" (instead of "On") and "0" (instead of "Off"). I don't know where the iPod Touch is different and why it's not showing correctly. Anyone had a similar experience? Is this a bug? Cheers

  • How to get address the object of an related entity with CoreData ?

    - by eemceebee
    Hi Ok, after I ran into a dead end modifieing an existing Apple example for CoreData, I started completely new creating my own project and that worked fine,..... until I tried to access a related entity. So here is what I did. I created 2 entities, where one is just the detail information of the other one, so there is a one-2-one relationship. Entity #1, Stocks: name value details -- relationship to Entity #2 Entity #2, StockDetails: bank published stock -- relationship to Entity #1 Now, I created the "Managed Object Class" for both of the Entities. Then I created a few lines to put some data into it NSManagedObjectContext *context = [self managedObjectContext]; Stocks *stockinfo= [NSEntityDescription insertNewObjectForEntityForName:@"Stocks" inManagedObjectContext:context]; stockinfo.name = @"Apple"; stockinfo.value = [NSNumber numberWithInt:200]; StockDetails *thestockdetails = [NSEntityDescription insertNewObjectForEntityForName:@"StockDetails" inManagedObjectContext:context]; thestockdetails.bank = @"Bank of America"; thestockdetails.published = [NSDate date]; thestockdetails.stock = stocks_; stockinfo.details = thestockdetails ; NSError *error; if (![context save:&error]) { NSLog(@"A Problem occured, couldn't save: %@", [error localizedDescription]); } Just want to mention here, that I do not get an error with this. Next I put everything into a UITableViewController for a preview and another for a detail view. The preview just shows infos form Entity #1 (Stocks) and when selected it shows the detail view. Now here I also display the infos form Entity #1 (Stocks) but I want to show the Entity #2 (StockDetails) aswell. This is how I try to access the data : StockDetails *details_ = [stockinfo details]; And this gives me a EXC_BAD_ACCESS. So any idea what I am doing wrong here ? Thanks

    - by Gregory Hill
    Has anyone successfully accessed AWS (Amazon E-Commerce Services) through Cocoa Touch? I've been digging around, and haven't seen the issue addressed directly. I've created an AWS account, and have seen some sample code for accessing web services through Cocoa, but I'm not quite sure how to tie it all together. If anyone has any sample code, I'd love to see it. I'm just trying to get my head around the concepts.

  • iPhone: Cocos2d how to make a sequence

    - by Johannes Jensen
    I have two logos, which I want to come in after each other. I'd like to use CCFadeIn and CCFadeOut. I have Logo1, and then I want it to CCFadeIn, then I want it to stay for 2 seconds, then make it fade out using CCFadeOut, and then make Logo2 CCFadeIn for 1 second, stay for 2 seconds and then go away during 1 second with CCFadeOut. How I would make this I'm not completely sure. I can't seem to find a way to make a CCAction fire a method (let's say -finishedFadingInLogo1:), so I don't know how to do this. Any ideas?

  • Weirdest occurrence ever, UIButton @selector detecting right button, doing wrong 'else_if'?

    - by Scott
    So I dynamically create 3 UIButtons (for now), with this loop: NSMutableArray *sites = [[NSMutableArray alloc] init]; NSString *one = @"Constution Center"; NSString *two = @"Franklin Court"; NSString *three = @"Presidents House"; [sites addObject: one]; [one release]; [sites addObject: two]; [two release]; [sites addObject: three]; [three release]; NSString *element; int j = 0; for (element in sites) { UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; //setframe (where on screen) //separation is 15px past the width (45-30) button.frame = CGRectMake(a, b + (j*45), c, d); [button setTitle:element forState:UIControlStateNormal]; button.backgroundColor = [SiteOneController myColor1]; [button addTarget:self action:@selector(showCCView:) forControlEvents:UIControlEventTouchUpInside]; [button setTag:j]; [self.view addSubview: button]; j++; } The @Selector method is here: - (void) showCCView:(id) sender { UIButton *button = (UIButton *)sender; int whichButton = button.tag; NSString* myNewString = [NSString stringWithFormat:@"%d", whichButton]; self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; self.view.backgroundColor = [UIColor whiteColor]; UINavigationBar *cc = [SiteOneController myNavBar1:@"Constitution Center Content"]; UINavigationBar *fc = [SiteOneController myNavBar1:@"Franklin Court Content"]; UINavigationBar *ph = [SiteOneController myNavBar1:@"Presidents House Content"]; if (whichButton = 0) { NSLog(myNewString); [self.view addSubview:cc]; } else if (whichButton = 1) { NSLog(myNewString); [self.view addSubview:fc]; } else if (whichButton = 2) { NSLog(myNewString); [self.view addSubview:ph]; } } Now, it is printing the correct button tag to NSLog, as shown in the method, however EVERY SINGLE BUTTON is displaying a navigation bar with "Franklin Court" as the title, EVERY SINGLE ONE, even though when I click button 0, it says "Button 0 clicked" in the console, but still performs the else if (whichButton = 1) code. Am I missing something here?

  • reloading table

    - by edie
    Hi... I've have a table view that consist of item list that depends on the item that were purchased using in app purchasing. My question was how can I reload the tableView when the purchasing was completed/(or when new item was added on my list). The response of the storekit takes time to complete. Are there anyways to tell the app that the purchasing was completed and new item was added on my list so that I can reload my tableView. At this time I reloading my table view by adding [myTableView reloadData] in viewWillAppear method. But what if the user was already viewing the tableView, I can't reload the tableView because the viewWillAppear had passed. thanks...
