  • Is this the correct way to reloadData on a UITableView?

    - by Sheehan Alam
    I am trying to append objects to my data source and then reload the table. Is this the correct way of approaching it? self.items is my datasource //Copy current items self.itemsCopy = [self.items mutableCopy];//[[NSMutableArray alloc] initWithArray:self.items copyItems:NO]; NSLog(@"Copy Size before append: %d",[itemsCopy count]); //Get new items int lastMsgID = [self getLastMessageID]; [self.coreData getMoreMessages:self.title lastID:lastMsgID]; //This will update self.items with 30 objects //Append new items [itemsCopy addObjectsFromArray:self.items]; //Empty items and copy itemsCopy [self.items removeAllObjects]; self.items = [self.itemsCopy mutableCopy]; NSLog(@"Actual Size after append: %d",[self.items count]); //Reload data [tableView reloadData];

How can I do that ?

  • Change Interval Of CADisplayLink

    - by user3679109
    I have replaced an NSTimer with a CADisplayLink. I have it working properly but it is running too slowly. How could I go about speeding this up? This is the code that I'm using: ViewController.h (In {} with @interface: CADisplayLink *displayLink; ViewController.m (viewDidLoad): displayLink = [CADisplayLink displayLinkWithTarget:self selector:@selector(onTimer)]; [displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes]; onTimer is the method that it is calling. So my question is how do I speed up how often this is being called? Thanks

  • Which trick uses Apple to show icons in the dock contextual menu ?

    - by Matthieu Riegler
    My question is quite simple : To use a custom menu for the apps icon on the dock, - (NSMenu*) applicationDockMenu: (id) sender; of the NSApplicationDelegate has to return the menu that the dock will display. Using setImage on a NSMenuItem, you can normaly add icons to the menu. They show up on the normal menu, but not on in contextual menu of the app's dock icon. Then how did Apple manage QuickTime, XCode, Preview to show icons in the list of recent opened files accessible in their dock contextual menu ? Thx.

    - by Paul
    I'd like to be able to determine which store the user connects to from inside my app, so that I can direct them to some appropriate content for their device AND store. Does anyone know how to get this information? Basically, if the user is in the UK, and connects to the UK store, I want my function/method to return GB, if in Korea, I want KR, Australia = AU etc. Any help would be appreciated.

  • What's safe to assume about the NSMutableArray / NSArray class cluster?

    - by andyvn22
    I know you shouldn't use this to decide whether or not to change an array: if ([possiblyMutable isKindOfClass:[NSMutableArray class]]) But say I'm writing a method and need to return either an NSMutableArray or an NSArray, depending on the mutability of possiblyMutable. The class using my method already knows whether or not it's acceptable to change the returned array. Whether or not it's acceptable to change the returned array directly correlates with whether or not it's acceptable to change possiblyMutable. In that specific case, is this code safe? It seems to me that if it's not acceptable to change the array, but we accidentally get a mutable array, it's ok, because the class using my method won't try to change it. And if it is acceptable to change the array, then we will always get possiblyMutable as an NSMutableArray (though this is the part I'm not entirely clear on). So... safe or not? Alternatives?

  • How to notify ViewController on parse end with multiple ViewControllers using a single parser.

    - by objneodude
    Hello, I have created a RSS parser and 3 TableViews and it parses the RSS files fine but I don't know how to notify the TableViewController when parsing has ended so it can update the view. The TableViewController initiates the parser and the parsing of a feed. parser = [[RSSParser alloc] initWithURL:@"http://randomfeed.com"]; I can access the single feed items like [parser feedItems]; In parser.m i have implemented the delegate methods of NSXMLParser: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName - (void)parserDidEndDocument:(NSXMLParser *)parser So how do i get parserDidEndDocument to notify my controllers so i can add the data to the tableview. Cheers from a obj-c beginner.

  • How do I run modals windows from code with cocoa?

    - by Leandro
    Hi,everybody I`m trying to run a window as modal directly from the code. My program starts and a main NSWindows is showed.A thread still running to see if the user has a valid distribution. if he doesn't I need to run a modal.I mean, I have no buttons clicked in the interface.I've designed a NSWindow on the interface builder for a password set, and I want to call it only when my validation is not successful. I have tested and realized that these methods which are responsible for modal windows running only work in a IBAction environment. //This doesn't work -(void) showPasswordWindow { [NSApp runModalForWindow:[self window]]; } //this works But its not useful for me =( - (IBAction) passwordWindowButton:(id)sender { [NSApp runModalForWindow:[self window]]; } Please, help this newbie =)

  • NSPredicate 'OR' filtering based on an NSArray of keys

    - by So Over It
    Consider the following NSArray: NSArray *dataSet = [[NSArray alloc] initWithObjects: [NSDictionary dictionaryWithObjectsAndKeys:@"abc", @"key1", @"def", @"key2", @"hij", @"key3", nil], [NSDictionary dictionaryWithObjectsAndKeys:@"klm", @"key1", @"nop", @"key2", nil], [NSDictionary dictionaryWithObjectsAndKeys:@"qrs", @"key2", @"tuv", @"key3", nil], [NSDictionary dictionaryWithObjectsAndKeys:@"wxy", @"key3", nil], nil]; I am able to filter this array to find dictionary objects that contain the key key1 // Filter our dataSet to only contain dictionary objects with a key of 'key1' NSString *key = @"key1"; NSPredicate *key1Predicate = [NSPredicate predicateWithFormat:@"%@ IN self.@allKeys", key]; NSArray *filteretSet1 = [dataSet filteredArrayUsingPredicate:key1Predicate]; NSLog(@"filteretSet1: %@",filteretSet1); Which appropriately returns: filteretSet1: ( { key1 = abc; key2 = def; key3 = hij; }, { key1 = klm; key2 = nop; } ) Now, I am wanting to filter the dataSet for dictionary objects containing ANY of the keys in an NSArray. For example, using the array: NSArray *keySet = [NSArray arrayWithObjects:@"key1", @"key3", nil]; I want to create a predicate that returns and array of any dictionary objects that contain either 'key1' or 'key3' (ie. in this example all dictionary objects would be returned except for the third object - as it does not contain either 'key1' or 'key3'). Any ideas on how I would achieve this? Would I have to use a compound predicate?

  • Best practices for parsing HTML from Wikipedia for iPhone viewing?

    - by ivanTheTerrible
    I am building an iPhone Wikipeida game app, that requires modifying the default Wiki HTML a little bit (mostly simplifying the page). So far I am directly downloading the HTML output from en.wikipedia.org/wiki/Article_Foo to a python Google App Engine, and then modify its CSS and HTML structure, cache it, and finally output to iPhone. It works but I find this method quite tedious, there must be a better method? Please note that I use App Engine not just for parsing the Wiki, but the game also requires it to keep the stores...etc, hence not a overkill. Also, I would prefer doing all the work with python on App Engine, to keep the iPhone client as thin and mobile as possible (XML on iPhone is a big no fun) Thanks a lot.

  • How to make same UIWebView take data from different local .html files?

    - by Mike Rychev
    I have an app, where there's one UIWebView and a UITableView. I don't want to create many .xib's, so I decided to make one .xib for all elements of the table. When user chooses a table element, the UIWebView appears and I want it to load data from different .html's depending on the name of the parent controller. I tried this: if (selectedTableElement==@"FirstElement") { [childController.message loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"_" ofType:@"html"]isDirectory:NO]]]; } And then myWebView=message; But it didn't work. Thanks in advance!
