  • Sending information back from delegate [iPhone]

    - by Andy
    I'm using NSXMLParser in my RootViewController.m file. NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:response_data]; [xmlParser setDelegate:self]; [xmlParser parse]; [xmlParser release]; I'm also implementing this method to add entries to a dictionary defined in RootViewController.m for later use: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict However, I'd like to get more than one XML file and do different things when the file has finished; this sounds like I need to use external files as delegates. My question is: If I have the following implementation files (& their header files): RootViewController.m XMLDelegate1.m XMLDelegate2.m and set the ith NSXMLParser delegate to be XMLDelegatei.m, and get those files to return an NSDictionary that I can then add to the NSDictionary defined in RootViewController.m. I guess there are two methods of doing this: Use a method that I don't know about; or Use a better workflow I suspect it's 2, but hope it's 1. Thanks, Andy

  • Async call Objective C iphone

    - by Sam
    Hi guys, I'm trying to get data from a website- xml. Everything works fine. But the UIButton remains pressed until the xml data is returned and thus if theres a problem with the internet service, it cant be corrected and the app is virtually unusable. here are the calls: { AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; if(!appDelegate.XMLdataArray.count > 0){ [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [appDelegate GetApps]; //function that retrieves data from Website and puts into the array - XMLdataArray. } XMLViewController *controller = [[XMLViewController alloc] initWithNibName:@"MedGearsApps" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; [controller release]; } It works fine, but how can I make the view buttons functional with getting stuck. In other words, I just want the UIButton and other UIButtons to be functional whiles the thing works in the background. I heard about performSelectorInMainThread but i cant put it to practice correctly any help is appreciated :)

  • iPhone + upgrade existing paid application on app store to free application with In App purchase + w

    - by pratik
    Hello, I have implemented In App purchase in my existing application. This application is currently available on app store as paid application, I want to update this paid application to free application with this In App purchase feature, where users can download it freely and have to pay for few features to unlock them. But the problem is that, if I update the existing paid application as free application (with few features locked and user has to buy it to unlock it), what about the users who have already purchased this application. Because when they will update to new free application, few features will be locked and they have to pay again to unlock them (why should they pay, if they have already purchased whole application previously). Regards, Pratik

  • Implementing Multitasking on an iPhone/iOS4 Web App

    - by Peter Watts
    I am looking to build a web app that implements background audio and fast app switching. These features work out of the box, when run as regular Safari web pages, but as soon as you add the web-app-capable tag, and try to run in full screen mode, this functionality breaks. I did some testing and even the most basic web app will reload every time when you switch back to it. And seeing as it's a web app, we can't exactly implement the multitasking API. Has anyone found a work around? This isn't a deal-breaker, as you can just avoid full screen mode, but then you also lose the ability to use your own icon in the app switch tray. Perhaps this explains a lack of full screen mode in YouTube's new web app....

  • iphone core data loop array and save each

    - by Matt Facer
    I have a core data model with two tables (meal and ingredients). I am trying to save ONE meal with MANY ingredients. I have the code below which loops through an array of ingredients. I'm trying to save it, but I cannot redeclare the "entity" below. How do I do it? I've tried releasing it, but that didn't work! Thanks for any help. for (x=0;x<ingredients;x++) { NSEntityDescription *entity = [NSEntityDescription insertNewObjectForEntityForName:@"Ingredient" inManagedObjectContext:managedObjectContext]; entity.name = @"test"; } (this method does work saving ONE record out of the loop.. so that's not the problem)

  • Moving a Ball on iPhone

    - by Chandan Shetty SP
    I am using below formula to move the ball circular, where accelX and accelY are the values from accelerometer, it is working fine. But the problem in this code is mRadius(I fixed its value to 50), i need to change mRadius according to accelerometer values and also i need bouncing effect when it touches other circles please send your answers ASAP... I am waiting. float degrees = -atan2(accelX, accelY) * 180 / 3.14159; int x = cCentrePoint.x + mRadius * cos(degreesToRadians(degrees)); int y = cCentrePoint.y + mRadius * sin(degreesToRadians(degrees)); Here is the snap of the game i want to develop. http://iphront.com/wp-content/uploads/2009/12/bdece528ea334033.jpg.jpg

  • iphone: unrecognized selector sent to instance

    - by eshalev
    I am new to objective C, So maybe there is some basic thing that I am missing about selectors. I would like to understand the basic concept behind this error as I have not found an general error reference. I am getting this error when using: [CloseButton addTarget:PageContents action:@selector(CloseButtonPressed) forControlEvents:UIControlEventTouchUpInside]; and then later: - (void)CloseButtonPressed:(id)sender{ UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Comment" message: @"hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil]; [someError show]; [someError release]; }

    - by Kevin
    Hello everyone I have this code below: NSString *fileName = [[NSUserDefaults standardUserDefaults] objectForKey:@"recentDownload"]; NSString *fullPath = [NSBundle pathForResource:fileName ofType:@"txt" inDirectory:[NSHomeDirectory() stringByAppendingString:@"/Documents/"]]; NSError *error = nil; [textViewerDownload setText:[NSString stringWithContentsOfFile:fullPath encoding: NSUTF8StringEncoding error:&error]]; textviewerdownload is the textview displaying the text from the file. The actual file name is stored in an NSUserDefault called recentDownload. When I build this, I click the button which this is under, and my application crashes. Is there anything wrong with the syntax or just simple error?

  • [iPhone app] Inserting special char un NSString for URL use

    - by Dough
    Hi, I'm using HTTP connection to share data with my JSON server. I use URLs like "MyServlet?param1=value1" and so on... I'm now facing a problem with one of my servlet (I can't change it because some other views are using it) : The servlet is working with a syntax including those symbols "{" and "}". The exact syntax is {(value1_value2)(value3_value4)(value5_value6)}{(value7_value8)(value9_value10)(value11_value12)}{(value13_value14)(value15_value16)(value17_value18)} Values are integers, the problem is only when I use "{" and "}" my UrlConnection returns an error for bad URL. I use this to instantiate my NSString : NSString *myURL = [NSString stringWithFormat:@"http://somesite.com/Servlet?PARAM={(%@)}"]; How can I code those char in my NSString ? Thanks in advance !

  • iPhone - UITableViewController not loading table

    - by RyanJM
    I'm pushing a UITableViewController onto a navigationController. The title (set in the viewDidLoad) shows up but not the table. numberOfSectionsInTableView is called. But tableView:numberOfRowsInSection: is not called. I'm passing in 1 so it should be looking for number of rows. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } I'm setting up the view in the following manner: SelectUserViewController *nextController = [[SelectUserViewController alloc] initWithStyle:UITableViewStyleGrouped]; nextController.managedObjectContext = managedObjectContext; OrangeQCAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [delegate.navigationController pushViewController:nextController animated:YES]; Again, the viewDidLoad method is called. And my class is set up as follows: @interface SelectUserViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource> {...} What else should I be looking at? When I go through the debugger, after it looks at numberOfSectionsInTableView it just disappears (I think it is in the UITableViewController class) and never comes back.

  • Big problems on iPhone ad hoc build -

    - by phil swenson
    No matter what I do I can't get my ad hoc provisioning profile to work. In Organizer, I always get "A valid signing identity matching this profile cannot be found in your keychain" for my adhoc profile. I have my distribution cert installed in my login keychain. I dragged the adhoc mobileprovision file to XCode... that's pretty much all there is to it, right? I searched around and found suggestions like re-creating the cert/profile. Did that, same thing. Also make sure your login keychain is default. It is. Even tried a different computer. Same result. In XCode AdHoc target I don't have a distribution target to pick. This all used to work, but obviously I messed something up..... Perhaps my process is just wrong (it's been months since I did this). Does someone have a step by step list of how to set up for adhoc distribution?
