  • Using Ruby/Python code in an iPhone OS app?

    - by igul222
    My app needs to use a library which is only available for Python and Ruby. From my understanding, Apple allows Ruby to run on iPhone as long as users can't execute arbitrary code (Rhomobile uses Ruby). How can I bundle Ruby/Python with my app, call a function from my Obj-C code, and get the result (a string) back in C or Obj-C format?

  • Where to start learning open-gl es

    - by Captain Kidd
    Hi everybody, I decide to learn OPEN-GL ES for IPHONE development, but I know nothing about graphics programing. So I've some questions. 1 I know OPEN-GL ES is a series of open standard API. IPHONE still use these standard API or apple define it's own API for OPENGL ES? 2 Before I start to learn OPEN-GL ES, I think I should be familiar with OPEN-GL. Am I right?

  • UITableView: Handle cell selection in a mixed cell table view static and dynamic cells

    - by AlexR
    I am trying to mix dynamic and static cells in a grouped table view: I would like to get two sections with static cells at the top followed by a section of dynamic cells (please refer to the screenshot below). I have set the table view contents to static cells. Edit Based on AppleFreak's advice I have changed my code as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell; if (indexPath.section <= 1) { // section <= 1 indicates static cells cell = [super tableView:tableView cellForRowAtIndexPath:indexPath]; } else { // section > 1 indicates dynamic cells CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section]; cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; } return cell; } However, my app crashes with error message Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:' for section 0 and row 0. The cell returned from cell = [super tableView:tableView cellForRowAtIndexPath:indexPath] for section 0 and row 0 is nil. What is wrong with my code? Could there be any problems with my outlets? I haven't set any outlets because I am subclassing UITableViewController and supposedly do not any outlets for tableview to be set (?). Any suggestions on how to better do it? Edit II I have recreated my scene in storyboard (please refer to my updated screen shot above) and rewritten the view controller in order to start from a new base. I have also read the description in Apple's forum as applefreak suggested. However, I run in my first problem with the method numberOfSectionsInTableView:tableView, in which I increment the number of static sections (two) by one. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return [super numberOfSectionsInTableView:tableView] + 1 ; } The app crashed with the error message: Terminating app due to uncaught exception 'NSRangeException', reason: '* -[__NSArrayI objectAtIndex:]: index 2 beyond bounds [0 .. 1]' Why is this code not working for me even though I followed Apple's and applefreak recommendations? It is possible that the tableView has changed a bit in iOS 6? Solution: I got this to work now using AppleFreaks code sample in his answer below. Thank you, AppleFreak! Edit III: Cell Selection: How can I handle cell selection in a mixed (dynamic and static cells) cell table view? When do I call super and when do I call self tableView? When I use [[super tableView] selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone] and try to check for the selected index paths with: UITableView *tableView = [super tableView]; if ( [[tableView indexPathForSelectedRow] isEqual:customGrowthIndexPath] ) { .. } I get an return value of nil. As I can't find the source of my error, I really would appreciate your help

    - by Mickey Shine
    I am just wondering is there a way to convert nib/xib file to ojbective C code?

    - by Joey
    I am trying to launch an appstore page with either of the calls: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://itunes.apple.com/us/app/myappname/id999999999?mt=8"]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.itunes.com/apps/myappname"]]; Both of these urls work when I enter them in a browser. However, from both simulator and device, I get a "Your request could not be completed" error dialog right after it appears to try to launch the appstore. Is there something obvious that I'm doing wrong?

    If I use the Finder's Go-Connect to Server and connect to an smb/afs, I can see the connection in netstat. But I can't see it in lsof. I also use LittleSnitch, and it fails to detect outbound connections from the Finder. Why is this? Is there some sort of "Apple rootkit" that i'm not aware of?

  • Python Script to check website for a tag

    - by LinuxGnut
    Hello all. I'm trying to figure out how to go about writing a website monitoring script (cron job in the end) to open up a given URL, check to see if a tag exists, and if the tag does not exist, or doesn't contain the expected data, then to write some to a log file, or to send an e-mail. The tag would be something like or something relatively similar. Anyone have any ideas?

  • iPhone "touchesBegan" and "touchesMoved" message ... do not move to centre of touch

    - by Nippysaurus
    I am modifying the "MoveMe" example from the apple web site. When I get the "touchesMoved" message I move the centre of the target view to the centre of the touch. Is there a way that when the touch starts ("touchesBegan" message) I can remember the offset from the target view and keep that offset. Let me know if this is hard to understand and I will try to explain it a bit better.

  • How do I allow an email discussion list in MOSS to collect messages from any email sender

    - by glenatron
    I have a Sharepoint discussion list that belongs to an Exchange list with the idea that it will be able to archive discussions on that list and make them generally accessible, searcheable and so on. The problem is that although I have checked the "Accept e-mail messages from any sender" option on the discussion board, it still appears to only be seeing emails from members of the domain, nothing sent to the list from outside gets picked up by the Sharepoint site. Any suggestions as to what else I have to do?

  • Issues adding search to iPhone app

    - by Graeme
    Hi, Basically I'm trying to add a search function to my iPhone app, but I'm not having much luck at the moment. I've downloaded the Apple provided Table Search app, and have copied across the code to mine. It builds OK, but here's the problem. Unlike the Apple example, all my data is stored in an array, that is accessed by calling [ciParser.currentArray]. Any ideas on how to change the code to suit my needs? I'm getting an error "Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)'" whenever I click on the search bar and the app exits. Below is the code in particular that the debugger highlights as being troublesome. Apparently this error means the database trying to be searched is empty, but I could be wrong. FYI my app downloads and parsers an RSS feed using a class which is referenced by ciParser - which in turn stores the downloaded content in an array that I need to search. // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } /* If the requesting table view is the search display controller's table view, configure the cell using the filtered content, otherwise use the main list. */ CurrentItem * nextCurrentItem=[ciParser.currentArray objectAtIndex:indexPath.row]; if (tableView == self.searchDisplayController.searchResultsTableView) { (Code which debugger points to as being wrong) nextCurrentItem = [self.filteredListContent objectAtIndex:indexPath.row]; } else { nextCurrentItem = [ciParser.currentArray objectAtIndex:indexPath.row]; } NSString*settingValue = [[NSUserDefaults standardUserDefaults]stringForKey:@"state"]; if ([settingValue isEqualToString:@"New South Wales"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"Western Australia"]) { cell.textLabel.text=@"The FESA does not provide any Current Incident reports."; } else if ([settingValue isEqualToString:@"Victoria"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"South Australia"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"Tasmania"]) { cell.textLabel.text=nextCurrentItem.title; } // Set up the cell... [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; return cell; }
