  • Download and Archive Web Pages on the iPhone

    - by Stefan
    Hi, how do I download and archive full web pages (HTML, CSS, JS, images) on the iPhone? I know how to download the single files. But is there any existing approach to get all files (e.g. all included javascripts), which are linked with a particular web page?

  • NSArraycontroller selectionIndexes bindings

    - by Michael Scherbaum
    Hi all, I have the following set-up: A Window that has a splitView in which I display I NSCollectionView in the left view and a detailView in the right view. Both views are set-up in separate xibs. Furthermore I have a Datacontroller (of class NSArrayController) that manages a mutable Array of NSMutableDictionaries (moviesForChoice). The dataController is set-up as application delegate. The movie objects in the array have properties like (name, plot, genre etc.) so far so good... In the xib for the NScollectionview I bound a NSArraycontroller content property to my datacontroller via Application.delegate.moviesForChoice The collectionView accesses the arraycontroller.arrrangedObjects and arraycontroller.selectionIndexes. This works fine the contents are displayed and the selection works fine in the collectionview (my collectionviewItem renders a selection color) In the xib for the detailView I want to display information for the selected object in the collectionview. Therefore I also added an arraycontroller to the xib, bound the content aray to Application.delegate.moviesForChoice and bound the NSTextfields in the view to e.g. arraycontroller.selection.name Here comes my issue: everytime I open the window with the two xibs, my collectionview displays all movies that are for choice correctly, and the detailview displays the information for the 1st object in my collectionview. Whenever I click on a different movie in the collectionView the res. item renders a selection color, but the detailView doesn't update. My understanding of it would be that the DataController is not informed about updates in the selectionIndexes and can therefore not trigger an update in the detailView. Correct me if I'm wrong... To remedy this I tried to bind the selectionIndexes property of the arraycontroller in the collectionView xib to Application.delegate.moviesForChoice.selecionIndexes but this failed with: addObserver:forKeyPath:options:context:] is not supported. Key path: selectionIndexes I could imagine that this means that the datacontroller is not KVO compliant for my Array moviesForChoice, but I implemented the following methods for it: -(void)insertObject:(NSDictionary *)dict inMoviesForChoiceAtIndex:(NSUInteger)index { [moviesForChoice insertObject:dict atIndex:index]; } -(void)removeObjectFromMoviesForChoiceAtIndex:(NSUInteger)index { [moviesForChoice removeObjectAtIndex:index]; } -(void)setMoviesForChoice:(NSMutableArray *)a { moviesForChoice = a; } -(NSArray*)moviesForChoice { return moviesForChoice; } -(NSUInteger)countOfMoviesForChoice { return [moviesForChoice count]; } - (void)addMovieForChoiceObject:(Movie *)anObject { [moviesForChoice addObject:anObject]; } So where am I wrong? How do I correctly bind to the selectionIndexes? You help is much appreciated! M

  • Scrollbars for Infinite Document?

    - by andyvn22
    Is there a standard Aqua way to handle a practically infinite document? For example, imagine a level editor for a tile-based game. The level has no preset size (though it's technically limited by NSInteger's size); tiles can be placed anywhere on the grid. Is there a standard interface for scrolling through such a document? I can't simply limit the scrolling to areas that already have tiles, because the user needs to be able to add tiles outside that boundary. Arbitrarily creating a level size, even if it's easily changeable by the user, doesn't seem ideal either. Has anyone seen an application that deals with this problem?

  • GameKit Bluetooth Transfer Problem

    - by David Schiefer
    Hi, I am trying to send a file via Bluetooth using the GameKit framework. The problem I am having though is that I can only send one NSData object at a time, but I need to save it on the other end. this obviously isn't possible without knowing the filename, but i don't know how to transmit that. I've tried to convert it to a string NSData*data = [NSData dataWithContentsOfFile:urlAddress]; but i can only send one NSData object, not two. Has anyone come across this problem yet?

  • NSURL not instantiating properly

    - by taokakao
    Hi, I am new to IPhone developing. I have got very strange issue with NSURL which is driving me crazy. I want to instantiate NSURL object to use it in loading image. But instantiation never happens in proper way. It always says my url in invalid. Basically I use code like below: NSString *str = @"http://google.com"; NSURL *url = [NSURL URLWithString:str]; but I also have tried a lot of different modifications (with CFStringRef + CFURLCreateStringByAddingPercentEscapes and so on). All of them are not working for me. In debugger url is set to "Invalid". What it could be? I don't think this is algorithmic or environment issue. It could be about some settings? Have anyone any idea of what happens?

  • How to remove an observer for NSNotification in a UIView?

    - by sudo rm -rf
    Hello! I've added an observer in a custom UIView I've created under initWithFrame:. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateZipFromLocation:) name:@"zipFoundFromLocation" object:nil]; The problem is, this view is a subview. When the view is loaded again, it calls the initWithFrame message again, thus adding two observers and so on. How can I remove the observer when the view is going to disappear? Since it is a UIView, it says that viewWillDisappear:(BOOL)animated is not a valid method. Any ideas?

  • Custom cell and Delete/Move indicators

    - by Kamchatka
    Hello, I have a custom UITableViewCell. However, when I got in edit mode, I don't have any Delete and Move indicators appearing. The custom cell draws itself in the contentView. In layoutSubviews, I make sure there is space on the left and one the right of the contentView so that the controls can appear (if this was the problem). - (void)layoutSubviews { self.contentView.frame = CGRectMake(50, 0, self.frame.size.width - 100, sub.thumbnail.size.height + 20); } In the UITableViewController, I return YES in: - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath { How could I solve this lack of interactivity. Is there something specific for custom cells? Thanks!

  • ObjC get property name

    - by Joe Even
    Yes. I've searched a lot without success. I've looking for a way to get a property name as StringValue from inside a method. Lets say: My class has X Subviews from the Type UILabel. @property (strong, nonatomic) UILabel *firstLabel; @property (strong, nonatomic) UILabel *secondLabel; [...] and so on. Inside the method foo, the views are iterated as followed: -(void) foo { for (UIView *view in self.subviews) { if( [view isKindOfClass:[UILabel class]] ) { /* codeblock that gets the property name. */ } } } The Result should be something like that: THE propertyName(NSString) OF view(UILabel) IS "firstLabel" I've tried class_getInstanceVariable, object_getIvar and property_getName without Success. For Example, the Code for: [...] property_getName((void*)&view) [...] RETURNS: <UILabel: 0x6b768c0; frame = (65 375; 219 21); text = 'Something'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x6b76930>> But i'm looking for this kind of result: "firstLabel" , "secondLabel" and so on. Thanks for your help! Reagrds Joé

  • 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?

  • Reverse geocode street name and city as text

    - by Taylor Satula
    Hello, I have been having some trouble finding a good way to output just the street name and city as text (Infinite Loop, Cupertino shown here) that can be displayed in my iPhone app. This needs to be able to dynamically change as you change streets and city. I don't have the slightest idea of how to do this, I hope someone can help. I have attached a very rough image of what I am trying to acheave. I have found this (http://code.google.com/apis/maps/documentation/javascript/services.html#Geocoding) for google maps about how to reverse geocode using javascript, but what I do not understand is how this would be done in a iPhone development setting. I work in web design and I see how it would be done in HTML but I am very new to iPhone development and don't have the slightest clue of how it would be done here. If someone could spell out how to do this I would be extremely grateful. I cannot seem to find what I am looking for by searching Google.

  • Recursively listing, and storing, directory contents

    - by enchilada
    I know how to recursively list directory contents. I will be using Snow Leopard's enumeratorAtURL:includingPropertiesForKeys:options:errorHandler: method to do this. However I want to store my findings into a object hierarchy (of, say, objects of a custom FileOrDirectory class that has isLeaf, children, and count attributes). I need to pre-load the directory and file structure into such a object hierarchy, in order to do whatever I want with NSTreeController and whatnot. I guess the trickiest thing here is to get the children attribute correct in the object hierarchy. Any ideas?

  • Objective-C++ Memory Problem

    - by Stephen Furlani
    Hello, I'm having memory woes. I've got a C++ Library (Equalizer from Eyescale) and they use the Traversal Visitor Pattern to allow you to add new functionality to their classes. I've finally figured out how it works, and I've got a Visitor that just returns the properties from one of the objects. (since I don't know how they're allocated). so. My little code does this: VisitorResult AGLContextVisitor::visit( Channel* channel ) { // Search through Nodes, Pipes until we get to the right window. // Add some code to make sure we find the right one? // Not executing the following code as C++ in gdb? eq::Window* w = channel->getWindow(); OSWindow* osw = w->getOSWindow(); AGLWindow* aw = (AGLWindow *)osw; AGLContext agl_ctx = aw->getAGLContext(); this->setContext(agl_ctx); return TRAVERSE_PRUNE; } So here's the problem. eq::Window* w = channel->getWindow(); (gdb) print w 0x0 BUT If I do this: (gdb) set objc-non-blocking-mode off (gdb) print w=channel->getWindow() 0x300effb9 // an honest memory location, and sets w as verified in the Debugger window of XCode. It does the same thing for osw. I don't get it. Why would something work in (gdb) but not in the code? The file is completely a cpp file, but it seems to be running in objc++, since I need to turn blocking off. Help!? I feel like I'm missing some memory-management basic thing here, either with C++ or Obj-C. [edit] channel-getWindow() is supposed to do this: /** @return the parent window. @version 1.0 */ Window* getWindow() { return _window; } The code also executes fine if I run it from a C++-only application. [edit] No... I tried creating a simple stand-alone program since I was tired of running it as a plugin. Messy to debug. And no, it doesn't run in the C++ program either. So I'm really at a loss as to what I'm doing wrong. Thanks, -- Stephen Furlani

  • How to detect a gamepad button press on OSX 10.5 and higher?

    - by Steph Thirion
    How do I detect a button press on a USB gamepad on OSX 10.5 and higher? I can't wrap my head around the ridiculously complex HID Manager (even though apparently it was simplified with 10.5), and the code samples at Apple have thousands of lines of code that would take days to understand and isolate what I need, so I'd appreciate if someone posts a simple, and fully coded solution for this isolated problem. EDIT: so far all answers are links to source code or semi obscure libraries for all kinds of HID devices, which will require more research time than what I'd like to invest on this. I am starting a bounty to get an actual snippet of code that solves this simple problem (using an external library or not). EDIT POS BOUNTY: thanks to all for you help; but unfortunately the answer that has been automatically selected by the system is not working for me, can't figure out why; and the author has not yet replied to my comments. Any insight would be appreciated, but until a fix is found, anyone looking for resources on this topic should take this answer with a pinch of salt.

  • Any simple way to "resize" an NSBezierPath?

    - by d11wtq
    I have an NSBezierPath that I'm filling and stroking. I'd like to add some inner glow to the path (a light stroke, just inside of the outer stroke), and the thing that comes to mind is to use the same path shrunk by 1 pixel (the size of the line that is already )stroked. Is there a way to do this? Alternatively, is there some sort of pattern I can use when applying both a border (stroke) and a glow to a bezier path? Example, the (extremely subtle) inner glow on the Google Chrome tabs:
