  • How should I handle header files in a bundle?

    - by ldiqual
    I want to develop a program that relies on plugins (here: loadable bundles) to work. Multiple plugins are asked to use the same AFNetworking ressource to make network requests. However, I don't know where to put AFNetworking and CustomPluginProtocol headers. Here is how my program structure looks like for now: MyApp.xcodeproj - AFNetworking - Header.h - Plugins - Plugin1.xcodeproj - PrincipalClass.m - Plugin2.xcodeproj - PrincipalClass.m - Classes - CustomPluginProtocol.h - MainClass.m Of course, every principalClass from PluginN complies to the CustomPluginProtocol. Do the headers have to be copied in each bundle ? Can I just include the main program AFNetworking headers from my plugins ? If so (and that's what I do for now), I don't have any completion. How can I get it ? Edit Ok, so maybe I wasn't clear in my question. I want my plugins to use sources from the main application, let's say CommonClass.m and CommonClass.h. Do the plugins need CommonClass.h in their bundle, and if not, how do I enable completion when I'm in the plugin scope ?

  • What is sender?

    - by marty
    I can't find this answer anywhere. What does it mean when there's a sender parameter in a method header? Does it represent the instance that called it, or the method that called it?

  • Why are controls (null) in awakeFromNib?

    - by fuzzygoat
    This is a follow on from another question regarding why I could not set UIControls in awakeFromNib. The answer to that is that as you can see below the controls are nil in the awakeFromNib, although they are initialised to the correct objects by the time we get to viewDidLoad. I setup the view the same as I always do, should I be doing something different to access them here, the xib(nib) was designed and saved with the current version of Image Builder. CODE: @interface iPhone_TEST_AwakeFromNibViewController : UIViewController { UILabel *myLabel; UIImageView *myView; } @property(nonatomic, retain)IBOutlet UILabel *myLabel; @property(nonatomic, retain)IBOutlet UIImageView *myView; @end . @synthesize myLabel; @synthesize myView; -(void)awakeFromNib { NSLog(@"awakeFromNib ..."); NSLog(@"myLabel: %@", [myLabel class]); NSLog(@"myView : %@", [myView class]); //[myLabel setText:@"AWAKE"]; [super awakeFromNib]; } -(void)viewDidLoad { NSLog(@"viewDidLoad ..."); NSLog(@"myLabel: %@", [myLabel class]); NSLog(@"myView : %@", [myView class]); //[myLabel setText:@"VIEW"]; [super viewDidLoad]; } OUTPUT: awakeFromNib ... myLabel: (null) myView : (null) viewDidLoad ... myLabel: UILabel myLabel: UIImageView Much appreciated ... gary

  • Command line tool (PDF Workflow) in OSX that detects if key is down

    - by kroko
    Hello! I'm writing a OSX PDF Workflow in ObjC and C. A single executable ("UNIX Tool" as named in the Apple reference), that reads in the spooled PDF file, does some parsing. I'd like to give more functionality by enabling a key-down event handling, meaning - when user opens print dialog in an application - and chooses to left-mouse-click on the custom made pdf workflow to run it - depending on if a keyboard key is down (i.e. option key, but "any key down" would be enough for me) when running that workflow - a decision is made in the code. I have read NSEvent and Carbon Event Manager reference and it seems that in this case (a plain unix executable + not run as root) it's not possible. Or is it? Many thanks in advance, Kroko

  • How to detect if Safari is disabled on iPhone

    - by zorro2b
    How can you detect whether Safari has been disabled by parental controls on the iPhone? I know it is possible because the App X3Watch refuses to work until Safari is disabled. As far as I can see there is no api for the parental controls, so what technique can be used for this?

  • Non-deprecated replacement for NSCalibratedBlackColorSpace?

    - by uliwitness
    I'm implementing my own NSBitmapImageRep (to draw PBM image files). To draw them, I'm using NSDrawBitmap() and passing it the NSCalibratedBlackColorSpace (as the bits are 1 for black, 0 for white). Trouble is, I get the following warning: warning: 'NSCalibratedBlackColorSpace' is deprecated However, I couldn't find a good replacement for it. NSCalibratedWhiteColorSpace gives me an inverted image, and there seems to be no way to get NSDrawBitmap() to use a CGColorSpaceRef or NSColorSpace that I could create as a custom equivalent to NSCalibratedBlackColorSpace. I've found a (hacky) way to shut up the warning (so I can still build warning-free until a replacement becomes available) by just passing @"NSCalibratedBlackColorSpace" instead of the symbolic constant, but I'd rather apply a correct fix. Anybody have an idea?

  • How to extract the actual NSString from json object as NSArray

    - by Toran Billups
    I'm working with a large set of json and really just need the NSString representation of what's inside the NSArray -including all the { } My question is this - is their a better way than simply looping through each NSArray inside the main NSArray and outputting the description one by one? ie- the below is a start to this process but it's very brittle meaning I need to know each item inside the hat {} and this isn't something I actually care about. I just need the json string to move forward. The working code is below (thank you in advance!) NSString* responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; [responseData release]; NSArray* json = [responseString JSONValue]; NSArray* item = [json valueForKeyPath:@"d.data"]; NSArray* hatjson = [item objectForKey:@"hat"]; NSMutableString * result = [[NSMutableString alloc] init]; for (NSObject * obj in hatjson) { [result appendString:[obj description]]; } NSLog(@"the hat json is .. %@", result);

  • Textures loaded with NSOperation are blank

    - by Omega
    So I call this method: -(void)beginExecution { NSOperationQueue *queue = [NSOperationQueue new]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(execute) object:nil]; [queue addOperation:operation]; [operation release]; } Which triggers this: -(void)execute { [[CCSpriteFrameCache sharedSpriteFrameCache]addSpriteFramesWithFile:@"MyTexture.plist"]; loaded = YES; // This tells me whenever loading is done. } However, when I create a sprite and try to use the texture MyTexture.png, the sprite is a blank canvas. Why is that?

  • Sharing NSMutableArray

    - by Lucas Veiga
    Hey everbody, im trying to share a NSMutableArray to another xib. The cartList.codigo is a NSMutableArray from a shared class, according to James Brannan's tutorial (http://www.vimeo.com/12164589). When i count it, it gives me 1. But when i load the another view, gives me 0. Whats wrong? View that adds: self.produtoCodigo = [[NSMutableArray alloc]init]; [self.produtoCodigo addObject:@"aa"]; CartViewController *carrinho = [[CartViewController alloc] initWithNibName:@"CartViewController" bundle:[NSBundle mainBundle]]; CartList *lista = [[CartList alloc] init]; carrinho.cartList = lista; carrinho.cartList.codigo = self.produtoCodigo; NSLog(@"QTD %i", [carrinho.cartList.codigo count]); View that wants to load the item added: - (void) viewDidAppear:(BOOL)animated { self.produtoCodigo = self.cartList.codigo; NSLog(@"%i", [self.produtoCodigo count]); [super viewDidLoad]; } Im loading the CartList class in both. Thanks!

  • iPhone SDK: Check validity of URLs with NSURL not working??

    - by Chris
    hi, I'm trying to check if a given URL is valid and i'm doing it like this: - (BOOL)urlIsValid:(NSString *)address { NSURL *testURL = [NSURL URLWithString:address]; if (testURL == nil) { return NO; } else { return YES; } } Since "URLWithString" is supposed to return "nil" if the URL is malformed I thought this would work but it doesn't for some reason. Could someone please tell me why? Thanks in advance!

  • iPhone internationalization: falling back to a default language

    - by MihaiD
    Consider the following situation: We have two Localizable.string files, one in en.lproj and one in it.lproj When the user switches to English or Italian, the proper localized string is loaded using NSLocalizedString(@"keyword", nil) If one of the files is missing the keyword, the string is not retrieved Is there any way to make this macro load the string from a specific language if it's keyword is not found in the current locale's Localizable.string?

  • iphone float vs integer rounding?

    - by Rob
    Okay, from what I understand, an integer that is a fraction will be rounded one way or the other so that if a formula comes up with say 5/6 - it will automatically round it to 1. I have a calculation: xyz = ((1300 - [abc intValue])/6) + 100; xyz is defined as an NSInteger, abc is an NSString that is chosen via a UIPicker. I want the calculation (1300 - [abc intValue]) to add 1 to 100 for each 6 units below 1300. For example, 1255 should result in xyz having a value of 100 and 1254 should result in a value of 101. Now, I understand that my formula above is wrong because of the rounding principles, but I am getting some CRAZY results from the program itself. When I punched in 1259 - I got 106. When I punched in 1255 - I got 107. Why would it behave that way?

  • UISearchbar issue

    - by hmthur
    I am trying to add a UISearchbar to table header view. I have the icon in nib and have connected the outlets. Now in viewDidLoad, I am writing self.tableView.tableHeaderView = searchbar If i create a local var inside viewDidLoad, it shows up. But not the outlet or ivar one. But for some reason, the UISearchbar does not get displayed in the table. I am not sure what the issue is. Can a UISearchbar not be set in viewDidLoad OR is it something else? Please help.
