  • How to convert an NSArray of NSManagedObjects to NSData

    - by carok
    Hi, I'm new to Objective C and was wondering if anyone can help me. I am using core data with a sqlite database to hold simple profile objects which have a name and a score attribute (both of which are of type NSString). What I want to do is fetch the profiles and store them in an NSData object, please see my code below: NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"GamerProfile" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES]; NSArray *sortDecriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDecriptors]; [sortDescriptor release]; [sortDecriptors release]; NSError *error; NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; NSData *data = [NSKeyedArchiver archivedDataWithRootObject:items]; [self SendData:data]; [fetchRequest release]; When I run the code I'm getting the error "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[GamerProfile encodeWithCoder:]: unrecognized selector sent to instance 0x3f4b530'" I presume I have to add an encodeWithCoderClass to my core data NSManagedObject object (GamerProfile) but I'm not sure how to do this even after reading the documentation, My attempt at doing this is below. I'm not sure if I'm going along the right lines with this as get a warning stating "NSManagedObject" may not respond to '-encodeWithCoder'" I would really, really appreciate it if someone could point me in the right direction!! Thanks C Here is the code for my GamerProfile (CoreData NSManagedObject Object) with my attempt at adding an encodeWithCoder method... Header File #import <CoreData/CoreData.h> @interface GamerProfile : NSManagedObject <NSCoding> { } @property (nonatomic, retain) NSString * GamerScore; @property (nonatomic, retain) NSString * Name; - (void)encodeWithCoder:(NSCoder *)coder; @end Code File #import "GamerProfile.h" @implementation GamerProfile @dynamic GamerScore; @dynamic Name; - (void)encodeWithCoder:(NSCoder *)coder { [super encodeWithCoder:coder]; [coder encodeObject:GamerScore forKey:@"GamerScore"]; [coder encodeObject:Name forKey:@"Name"]; }

  • How do I replace a modal view controller?

    - by Theory
    I'm using a modal view controller to allow a user to select an address book entry and email address. The ABPeoplePickerNavigationController object is displayed via presentModalViewController:animated: [self presentModalViewController:picker animated:YES]; What I want to do is keep the modal dialog up, but when the user selects the email address, it should cross-fade to a different controller that displays a message composition window. I've tried various approaches in peoplePickerNavigationController:shouldContinueAfterSelectingPerson:property:identifier: to dismiss the picker and set my custom composition controller as the modal view. I can do it any number of ways, but never does it fade smoothly from the picker to the composition controller -- unless I make the composition controller a modal dialog of the picker, in which case the picker re-appears when I dismiss the composition controller. I don't want that, either. There must be some way to smoothly replace one controller and its view with another controller and its view, all within the context of a modal dialog, and preferably with a cross fade. Suggestions greatly appreciated.

  • MKMapView doesn't want to call didAddAnnotationViews method

    - by TheLearner
    I am writing a little map kit app but it doesn't want to call the delegate method didaddannotationviews: (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views { //Get the first MKAnnotationView from the views returned MKAnnotationView *annotationView = [views objectAtIndex:0]; //Get the annotation from the first annotation view and save it in a variable which can hold any object as long as it implements mkannotation id <MKAnnotation> mp = [annotationView annotation]; //Create a region MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance([mp coordinate], 250, 250); //As the mapview to animate i.e. display the region [mv setRegion:region animated:YES]; } @interface WhereAmIAppDelegate : NSObject { UIWindow *window; CLLocationManager *locationManager; IBOutlet MKMapView *mapView; IBOutlet UIActivityIndicatorView *activityIndicator; IBOutlet UITextField *locationTitleField; }

  • How to intercept UIScrollView contentOffset changes from UITableView subclass?

    - by mystify
    Actually, a UITableView is a UIScrollView (inherits from that). Now, I made a UITableView subclass and added this line of code to it: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { NSLog(@"contentOffset: %@", NSStringFromCGPoint(self.contentOffset)); } For some reason this is never called when I scroll the table view. But since UITableView has a delegate property on it's own, I assume that it must implement UIScrollViewDelegate protocol and is the delegate for the scroll view itself. Isn't it? How could I intercept scroll position changes? I want to read them only. Probably I couldn't set them with contentOffset, right?

  • UITableViewCellSeparatorStyleNone does not hide blue separator line when selecting in UITableView

    - by clozach
    Before describing the problem, let me first point out that this is a distinct issue from this question. The Problem This screenshot was taken with a break set at tableView:didSelectRowAtIndexPath:, and as you can see in the simulator (far right of the image), there's a single-pixel blue line at the bottom of the selected cell. This is not the design asked for by the client, nor is it how this app used to behave: there should be no separator, even on selection. How I Got Here I'd initially designed this table view using custom UITableViewCell classes with corresponding nib (.xib) files and had no trouble with selections: the separator was hidden as desired. Predictably, scrolling was sluggish due to all the overhead from the view hierarchy, so I reworked the custom cells to use Loren Brichter's fast scrolling solution. Now scrolling is much faster, but I can't get rid of the separator for the life of me. What I've tried At the time of the screenshot above... the table view has "Separator [None]" in IB. the UIViewController that contains the table view has this line in viewDid Load: self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone; As you can see in the screenshot, I inserted some unused lines to prove that separatorStyle is set as desired. Other testing confirms that tableView and self.tableView are equivalent pointers at that same breakpoint. I've also tried setting tableView.separatorColor to black and to clear, all with the same result: the cells look right until a selection is made.

  • JQTOUCH, Binding to links pulled in via AJAX, to make another AJAX call? Possible?

    - by nobosh
    Hello. I'm using JQTOUCH using the AJAX example provided in the demo: $('#customers').bind('pageAnimationEnd', function(e, info){ if (!$(this).data('loaded')) { // Make sure the data hasn't already been loaded (we'll set 'loaded' to true a couple lines further down) $('.loadingscreen').css({'display':'block'}); $(this).append($('<div> </div>'). // Append a placeholder in case the remote HTML takes its sweet time making it back load('/mobile/ajax/customers/ .info', function() { // Overwrite the "Loading" placeholder text with the remote HTML $(this).parent().data('loaded', true); // Set the 'loaded' var to true so we know not to re-load the HTML next time the #callback div animation ends $('.loadingscreen').css({'display':'none'}); })); } }); This then returns a nice UL which outputs just fine.. <ul class="edgetoedge"> <li class="viewaction" id="715"> <span class="Title"><a href="/c-view/715/">Lorem Ipsum is simply dummy text of the...</a></span> <div class="meta"> <span class="dateAdded"> 1d ago </span> </div> </li> </ul> This is where I get stuck. How can I then make it so when you click on the link above, it loads the URL wrapped near the class="Title" ? I'd like it to load JQTouch like the first code example. I tried the following two things without success: $('.viewaction').bind('click', function() { alert('wow'); }); $('.viewaction').live('pageAnimationEnd', function(e, info){ }); Thank you!

  • UINavigationController does not set view properties correctly when pushed

    - by Sheehan Alam
    I have a UITabBarControllerDelegate that pushes a new view controller when a certain tab is pressed: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { MyView* myView = [[[MyView alloc] initWithNibName:@"MyView" bundle:nil]autorelease]; if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; [self.navigationController myView animated:YES]; } } However, if I change my code to set the tabbar's selected view controller to myView everything works, but I don't get my navigation bar: if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; self.tabBarController.selectedViewController = myView; } How can I set the reloadFriends property in MyView and have the navigation bar at the top?

  • Get info on a mapview selected annotation

    - by rson
    I have annotations on a mapview and a callout with a button on each. What I need to do is grab properties from this callout, ie. the title, but logging this line: NSLog(@"%@", mapView.selectedAnnotations); returns <AddressAnnotation: 0x1bdc60> which obviously gives me no useful info... My question is, how can I access the properties of a selected annotation callout?

  • UIButton: how to center an image and a text using imageEdgeInsets and titleEdgeInsets?

    - by R31n4ld0_
    Hello, guys. If I put only an image in a button and set the imageEdgeInsets more close to the top, the image stays centered and all works as expected: [button setImage:image forState:UIControlStateNormal]; [button setImageEdgeInsets:UIEdgeInsetsMake(-15.0, 0.0, 0.0, 0.0)]; If I put only a text in a button and set titleEdgeInsets more close to the bottom, the text stays centered and all works as expected: [distractionButton setTitle:title forState:UIControlStateNormal]; [distractionButton setTitleEdgeInsets:UIEdgeInsetsMake(0.0, 0.0, -30, 0.0)]; But, if i put the 4 lines together one interfere with other and both lost the center alignment. All my images has 30 pixels widht, and if i put 30 in the left parameter of UIEdgeInsetMake for setTitleEdgeInsets, the text is centered again. The problem is that the image never gets centered because appears that it is dependent of the button.titleLabel size. I already tried many calculations with button size, image size, titleLabel size and never get both perfectly centered. Someone already have the same problem? Thanks in advance.

  • How to create an image from a UIView / UIScrollView

    - by Andre
    Hi, I have an image in an UIScrollView, that can be scrolled and zoomed. When the user presses a button, I want the code to create an image from whatever part of the UIScrollView is inside an area I specify with a CGRect. I've seen code to crop UIImages, but I can't adapt it to do the same for a view, because it uses CGContextDrawImage. Any thoughts? Cheers, Andre

  • UIPageControl in a ITableViewCell gets shoved to the top left corner

    - by Danny Tuppeny
    I'm trying to put a UIPageControl inside a cell (there's nothing else in the cell), but I have two problems: The dots are aligned at the top-left of the cell, so you only see the bottom-right quarter of the first dot, and the bottom half of the other dots (like the first dots center is 0, 0). Unless you tab the cell to select it (goes blue), you can't see the dots at all. Other controls I've put into a cell have filled the whole area as wanted. How do I tell the UIPageControl to fill the whole cell (and align in the middle) How do I change the colours so the dots can be seen? I tried calling [pageControl setBackgroundColor] but it didn't seem to do anything. Here's the code I'm using: // Create a page control UIPageControl *pageControl = [[[UIPageControl alloc] init] autorelease]; // Set the number of pages to match the images [pageControl setNumberOfPages:[imageFilenames count]]; [pageControl setCurrentPage:1]; // Create the cell and add the paging control UITableViewCell *cell = [self getCell:tableView withIdentifier:@"ImagePager"]; [cell addSubview:pageControl]; //[[cell textLabel] setText:@"ADD PAGING CONTROL"]; return cell;

  • Why won't my UISearchDisplayController fire the didSelectRowAtIndexPath moethod?

    - by John Wells
    I am having an odd problem when searching a UITableView using a UISearchDisplayController. The UITableViewController is a subclass of another UITableViewController with a working didSelectRowAtIndexPath method.

  • How can I use removeFromSuperView and dismissModalViewControllerAnimated at same time ?

    - by srikanth rongali
    I have a UIViewController *view1 and another UIViewController *view2; I used presentModelViewController to navigate from view1 to view2. -(void)function:(id)sender { NSLog(@"The libraryFunction entered"); LibraryController *libraryController = [[LibraryController alloc]init]; [self presentModalViewController:libraryController animated:YES]; } I have another view UITableViewController *tableView; I added it to view2 as a subView. -(void)viewDidLoad { RootViewController *rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController]; self.navController = aNavigationController; [aNavigationController release]; [rootViewController release]; navController.view.frame = CGRectMake(0, 0, 320, 460); [self.view addSubview:navController.view]; } In RootViewController.m I have - (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; } -(void)close:(id)sender { [self.view removeFromSuperview]; [self dismissModalViewControllerAnimated:YES]; } WhenI touch close button I need to return the view1. So, I removed the tableView by using removeFromSuperView. But, I am not able to get to the first view. I do not get where to use - (void)dismissModalViewControllerAnimated:(BOOL)animated; to navigate to first view1 where I have started ? How can I do this ? Thank You.

  • Clip UITableView Cell's Separator

    - by Drewsmits
    I've been trying to build a view that looks similar to the "stocks" application (surprise). What I would like is to have the scroller bar outside of my rounded table view, shown in the image link below, but clip the cell separators. You can see how they overlap the scroller bar, which is annoying. I can't figure out how Apple put the scroller bar in a spot that looks like it is outside their table. Any ideas? (sorry, can't imbed images yet because I'm a new user). Scroller Problem Image

Well, with this code I get only the fade-in step, since the UILabel suddenly disappear, then fades-in. Some suggestion? Thanks.

  • MFMailComposeController crashing non-deterministically

    - by sss
    Hello, I've been struggling with this issue for a few days. I am trying to use the MFMailComposeController to send emails. What's happening is that the program crashes (long stack-trace below) upon clicking the SEND button. However, this is non-deterministic - sometimes it works immediately, sometimes after a long delay, and most often, it crashes. Here's my code for sending: -(void)mailWithAttachment:(NSString *) fileName type:(NSString*) attachmentType data:(NSData *) attachmentData { MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init]; mc.mailComposeDelegate = self; if ([MFMailComposeViewController canSendMail]) { [mc setSubject:@"my subject"]; [mc setMessageBody:@"my body" isHTML:YES]; [mc addAttachmentData:attachmentData mimeType:attachmentType fileName:fileName]; [self presentModalViewController:mc animated:YES]; } [mc release]; } didFinish result looks like you'd imagine: -(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { [self dismissModalViewControllerAnimated:YES]; //...some other actions here for other UI logic, but problem persists if removed } And the definition of the class: @interface ShareViewController : UIViewController { //... } Here's the stack trace: #0 0x33568534 in gdb_objc_debuggerModeFailure #1 0x3356634e in _rwlock_write_nodebug #2 0x33560940 in map_images #3 0x2fe0413e in __dyld__ZN4dyldL18notifyBatchPartialE17dyld_image_statesbPFPKcS0_jPK15dyld_image_infoE #4 0x2fe042d4 in __dyld__ZN4dyldL11notifyBatchE17dyld_image_states #5 0x2fe0aee0 in __dyld__ZN11ImageLoader4linkERKNS_11LinkContextEbbRKNS_10RPathChainE #6 0x2fe062d6 in __dyld__ZN4dyld4linkEP11ImageLoaderbRKNS0_10RPathChainE #7 0x2fe08188 in __dyld_dlopen #8 0x30c18fd0 in dlopen #9 0x0000390c in <function called from gdb> #10 0x3356628e in getMethodNoSuper_nolock #11 0x335662b8 in _class_getMethodNoSuper_nolock #12 0x3356518a in lookUpMethod #13 0x33562914 in _class_lookupMethodAndLoadCache #14 0x3356264a in objc_msgSend_uncached #15 0x33562a2a in _class_initialize #16 0x33567dfe in prepareForMethodLookup #17 0x33565168 in lookUpMethod #18 0x33562914 in _class_lookupMethodAndLoadCache #19 0x3356264a in objc_msgSend_uncached #20 0x32b2c288 in +[NSTimeZone(NSTimeZone) defaultTimeZone] #21 0x32b2c246 in -[NSCalendarDate initWithTimeIntervalSinceReferenceDate:] #22 0x32b3beb4 in -[NSDate(NSCalendarDateStuff) descriptionWithCalendarFormat:timeZone:locale:] #23 0x323642fc in -[NSDate(Goodies) descriptionForMimeHeaders] #24 0x32a6e812 in -[MailComposeController headersUseSuspendInfo:] #25 0x32a71e38 in -[MailComposeController messageUseSuspendInfo:endingEditing:] #26 0x32a6e594 in -[MailComposeController _getMessage:] #27 0x32a6e536 in -[MailComposeController message] #28 0x32a72bcc in -[MailComposeController deliverMessageRemotely] #29 0x32a7cab0 in -[_MFMailComposeRootViewController mailComposeControllerCompositionFinished:] #30 0x32a6e0a0 in -[MailComposeController sendMessage] #31 0x32a7086a in -[MailComposeController send:] #32 0x32c29ffa in -[NSObject performSelector:withObject:] #33 0x32a661cc in -[MailComposeView _sendButtonClicked:] I've tried the MFMailComposeController as a child of different views with the same result.

  • How to create a view controller that supports both landscape and portrait, but does not rotate between them (keeps its initial orientation)

    - by Joshua J. McKinnon
    I want to create a view controller that supports both landscape and portrait orientations, but that can not rotate between them - that is, the view should retain its original orientation. I have tried creating an ivar initialOrientation and setting it in -viewDidAppear with initialOrientation = self.interfaceOrientation; then - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == initialOrientation); } But that causes confusing problems (presumably because -shouldAutorotateToInterfaceOrientation is called before -viewDidAppear). How can I lock the orientation to its original orientation?

  • drawTextInRect on UITextField not called

    - by subw
    I'm trying to implement the answer to this SO question. The problem is: -[drawTextInRect] is apparently not called, and setting the shadow in -[drawRect] doesn't make the UITextField's text shadowed. Another weird thing is that even if my subclass implementations of -[drawTextInRect] and -[drawRect] are completely empty (not even a call to super), the textfield's text is drawn.

  • Does it make sense to use a NSFetchedResultsController without an UITableViewController? How are the

    - by dontWatchMyProfile
    I mean... could I also just create a plain old UIViewController and then set up a UITableView myself, plus an NSFetchedResultsController? How much do UITableViewController and NSFetchedResultsController interact with eachother? As far as I see it, UITableViewController is NOT by default already adopting the NSFetchedResultsControllerDelegate protocol. It almost looks like if UITableViewController has been developed without knowing about NSFetchedResultsController. Probably they even did that before developing FRC. Anyways, just a raw guess because the UITableViewController lacks of mentioning FRC at all. So the only thing I see in UITableViewController is that it is already the delegate for a UITableView by adopting the protocol, and it sets up the UITableView instance for me and assigns it internally to it's tableView property. Is that the whole magic of UITableViewController? (note: the nsfetchedresultscontrolle tag is not a typo. SO has a limit for the num of chars...too bad for that missing r, that's why I avoided this tag in my other buch of questions like the plague)
