  • Display shift when adding rows to UITableView

    - by Kamchatka
    Hello, I have a UITableView displaying an underlying NSFetchedResultsController. When the fetchedResultsController is updated, - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { is called. And the following is executed: case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:shiftedIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; The cellForRowAtIndexPath is only called for the new line (which is logical) The problem is however that all the values displayed in the rows of the table view are shifted down. The first row displays its title. The second rows displays the first row's title. The third row the second row's title etc. If I repeat that, the third row will display the second's row title, the fourth the third row's title etc. I don't understand what can happen, especially because cellForRowAtIndexPath is only called for the new line (which is logical) and not for all these lines. Additionally, if I click on these lines which have the wrong title, it opens the right document (didSelectRowAtIndexPath works correctly with the indexPath) Any clue of what could happen? Thanks!

Click “Install and Run” to install the provisioning profile “distribution” on “myphone” and continue running “helloworld.app”. and it has a button "install and run" ive clicked on that hundreths of times and nothing. in orgranizer i see a tab called console ive cleared it and rebuild the app and there is some output that i dont understand.

  • Using plist to populate a grouped table

    - by Jack Griffiths
    Hi there, I was wanting to use a plist to populate my grouped table. I've had a look at the DrillDownSave sample project, and I'm still none-the-wiser. Although, I did learn that I could store hierarchies and suchlike in there. So here's the questions: How can I use my plist to add new items to my grouped table? I'm currently feeding the table with an array, and I've noticed that an array isn't going to be the best thing for me. When a user taps on an item in the plist, how can I push the view to the corresponding item? In other words, how can I push the view based on the selected row (which was generated by the plist) to it's next "view"? If that makes any sense, please reply. Thanks, Jack.

  • Adding resources to solution explorer in experimental hive

    - by Brian Webb
    Hi, I'm currently working on a project using DSL tools in Visual Studio 2008. Is there a way to automatically add a resource into the solution explorer of the experimental hive at runtime? I'm creating new diagrams based on what is on screen, and saving them into the directory the project is stored in. I would like to know if there is a way to get them to automatically get added to the solution explorer? (I don't want to have to drag the files in manually each time)

  • How can I grab the iTunes-defined name for my iPhone/iPod device?

    - by Christophe Porteneuve
    Hey there, I'm trying to get the name for an iPhone/iPod device that the user entered in their iTunes. This is not, I repeat, not, necessarily what [[UIDevice currentDevice] name] returns (or any of its other methods). For instance, my iPhone is bound in iTunes to "iPhone 3G de Christophe…", to differentiate it from my wife's and other similar devices. That's the name I'd love to be able to grab. Is it stored anywhere on the device, and if so can I access it somehow? Thanks!

  • How to auto-increment reference number persistently when NSManagedObjects created in core-data.

    - by KayKay
    In my application i am using core-data to store information and saving these data to the server using web-connectivity i have to use MySql. Basically what i want to do is to keep track of number of NSManagedObject already created and Whenever i am adding new NSManagedObject, based on that counting it will assign the class a Int_value which will act as primary_key in MySql. For examaple, there are already 10 NSManagedobjects, and when i will add new one it will assign it "11" as primary_key. these value will have to be increasing because there is no deleting of NSManagedObject. From my approach its about static member in applicationDelegate whose initial value can be any integer but should be incremented by one(like auto-increment) everytime new NSManagedObject is created and also it should be persistent. I am not clear how to do this, please give me suggestions. Thanks in advance.

  • Toubleshooting mapkit performance

    - by brettr
    I'm plotting over 500 points on a map using mapkit. Zooming is a little jittery compared to the native google map app. I've discovered what is causing the slowness. I'm adding custom annotations so that I can later add different pin colors and buttons for detail views: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(AddressNote *) annotation { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentlocation"]; annView.pinColor = MKPinAnnotationColorGreen; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } If I comment out the above code, everything works fine. Very smooth with zooming in/out. Should I be adding annotations differently to boost performance?

  • Custom URL Scheme from settings.bundle

    - by S-T-R-E-G-A
    Is it possible to set a custom URL scheme to launch my app from a link but make this a user defined setting? My app relies on a user defined server url and I would like to be able to set a URL scheme to launch my app using the users custom URL from lets say an email link. I noticed the info.plist has these references ${EXECUTABLE_NAME} can I define my own custom reference maybe?

  • iPad title bars. Navbars or toolbars?

    - by Squeegy
    I see a bunch of apps for iPad with really cool title bars. These seem to be a combination of a navigation bar and a toolbar. They usually have a back button and a title as well as men other buttons. And a navbar only supports a left item, a right item and and title view. And the toolbar does not really support back buttons or titles. So how do I implement these rich navbars with many buttons on my UINavigationController driven application?

  • UIView frame origin doesn't set good

    - by Infinity
    Hi guys! Here is my code: frame = _pageContentView.frame; NSLog(@"%f; %f; %f; %f;", frame.origin.x, frame.origin.y, frame.size.width, frame.size.height); frame.size.height = pageContentView.frame.size.height; NSLog(@"%f; %f; %f; %f;", frame.origin.x, frame.origin.y, frame.size.width, frame.size.height); _pageContentView.frame = frame; NSLog(@"%f; %f; %f; %f;", _pageContentView.frame.origin.x, _pageContentView.frame.origin.y, _pageContentView.frame.size.width, _pageContentView.frame.size.height); And the NSLog outputs these values: 0.000000; 0.000000; 317.648956; 0.000000; 0.000000; 0.000000; 317.648956; 768.000000; 0.000007; 0.000004; 317.648956; 768.000000; Can you see? In the last row the x and y coordinates are a bit crazy... Where do these number come frome? What's the problem here?

  • touchesBegan and other touch events not getting detected in UINavigationController

    - by SaltyNuts
    In short, I want to detect a touch on the navigation controller titlebar, but having trouble actually catching any touches at all! Everything is done without IB, if that makes a difference. My app delegate's .m file contains: MyViewController *viewController = [[MyViewController alloc] init]; navigationController = [[UINavigationController alloc] initWithRootViewController:viewController]; [window addSubview:navigationController.view]; There are a few other subviews added to this window in a way that overlays navigationController leaving only the navigation bar visible. MyViewController is a subclass of UIViewController and its .m file contains: - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for (UITouch *touch in touches) { NSLog(@"ended\n"); } } -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { for (UITouch *touch in touches) { NSLog(@"began\n"); } } I also tried putting these functions directly into app delegate's .m file, but the console remains blank. What am I doing wrong?

  • Is it posible to Build & Run on TWO iPhones/iPods at once?

    - by Dimitris
    When I connect two iPhones at the same time to my computer and Build and Run a project the app only installs and plays on one of the devices. Now, with the iPhone 3.0, that supports bluetooth peer-to-peer connectivity, to test a multiplayer project you have to install and run it on two devices at the same time. It would be very helpful to be able to do that with one click instead of: install on one phone, disconnect, connect the other, wait a 10 seconds to recognize the phone and install again and run... Is anyone aware of a method to do such a thing? Thanks

  • UIScrollView + UIWebView = NO scrollsToTop

    - by sniurkst
    It looks like a problem which could have simple solution, but I haven't found anything what could lead the way to it. I'm using UIWebView inside of UIScrollView and tapping on statusBar (to scroll content to top) is not working. I've made simple test application to see if it's really UIWebViews fault. And it really is. // scrolls to top on status bar tap UIScrollView *sv = [[UIScrollView alloc] init]; sv.frame = CGRectMake(0, 0, 320, 480); sv.contentSize = CGSizeMake(320, 1200); [self.view addSubview:sv]; // doesn't scroll UIScrollView *sv = [[UIScrollView alloc] init]; sv.frame = CGRectMake(0, 0, 320, 480); sv.contentSize = CGSizeMake(320, 1200); UIWebView *wv = [[UIWebView alloc] init]; wv.frame = CGRectMake(0, 0, 320, 100); [sv addSubview:wv]; [self.view addSubview:sv]; So, I think maybe there's something I could disable to make UIWebView not to mess with scrollToTop? Or some kind of workaround also would be nice. Any ideas?

  • Sorting array containing strings in objective c

    - by jakob
    Hello experts! I have an array named 'names' with strings looking like this: ["name_23_something", "name_25_something", "name_2_something"]; Now I would like to sort this array in ascending order so it looks like this: ["name_25_something", "name_23_something", "name_2_something"]; I guess that should start of with extracting the numbers since I want that the sorting is done by them: for(NSString *name in arr) { NSArray *nameSegments = [name componentsSeparatedByString:@"_"]; NSLog("number: %@", (NSString*)[nameSegments objectAtIndex:1]); } I'm thinking of creating a dictionary with the keys but I'm not sure if that is the correct objective-c way, maybe there some some methods I could use instead? Could you please me with some tips or example code how this sorting should be done in a proper way. Thank you

  • iPhone: Push Navigation Controller (w/ TableViewController) onto stack. Is this possible?

    - by Nic Hubbard
    I have a view which contains a UIButton. When this is clicked, it calls a method that loads another NIB. Now, normally, that nib would load a view onto the stack, and everything would be fine. But, I am trying to load a Navigation Controller (so that I can have table views that are multiple levels deep), and all I get it errors. What is the proper method for loading a Navigation Controller and putting it on the top of the stack?
