  • AdressBook Crash, only with some contacts!

    - by Zebs
    My app crashes, it is a problem that arises from the AddressBook API, it only happens with some contacts.

Any help would be greatly appreciated. Here is the code that was requested, thank you very very much for your help: (It is an extract from the method where I think the error happens) The weird thing is that it only happens with certain contacts, and deleting the contact, then creating a new one solves the problem... - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier NSString* firstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); NSString* lastName = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty); NSNumber* record = [NSNumber numberWithInt:ABRecordGetRecordID(person)]; if(lastName!=nil){ name=[NSString stringWithFormat:@"%@ %@",firstName,lastName]; } else { name=firstName; } ABMultiValueRef phone = ABRecordCopyValue(person, property); NSString *value =(NSString *)ABMultiValueCopyValueAtIndex(phone, identifier); NSString *label =(NSString *)ABMultiValueCopyLabelAtIndex(phone, identifier); NSMutableArray *tempArray=[[NSMutableArray alloc] initWithArray:[[NSUserDefaults standardUserDefaults] objectForKey:@"MainArray"]]; NSDictionary *stringDictionary = [NSDictionary dictionaryWithObjectsAndKeys:name, kLabelKey, value, kNumberKey,label, kNumberLabelKey,record, kReferenceKey, nil]; [tempArray addObject:stringDictionary]; NSArray *mainArray = [NSArray arrayWithArray:tempArray]; [[NSUserDefaults standardUserDefaults] setObject:mainArray forKey:@"MainArray"];

  • setting target for disclosure button on subclassed UITableViewCell

    - by Toby Wilson
    I've created a subclass of UITableViewCell to create some custom appearance and UI functionality ('swipe to reveal delete button'). Some of the cells are disclosure/detail disclosure type, and have a UIButtonTypeDetailDisclosure etc added manually. I cannot use the table view controllers' UITableViewCellAccessory for row at index path method. The question is, how do I set the target of these manually added buttons so that they correctly send the didSelectRowAtIndexPath to their table view controller?

  • How to make UISlider output nice rounded numbers exponentially?

    - by RickiG
    Hi I am implementing a UISlider a user can manipulate to set a distance. I have never used the CocoaTouch UISlider, but have used other frameworks sliders, usually there is a variable for setting the "step" and other "helper" properties. The documentation for the UISlider deals only with a max and min value, and the output is always a 6 decimal float with a linear relation to the position of the "slider nob". I guess I will have to implement the desired functionality step by step. To the user, the min/max values range from 10 m to 999 Km, I am trying to implement this in an exponential way, that will feel natural to the user. I.e. the user experiences a feeling of control over the values, big or small. Also that the "output" has reasonable values. Values like 10m 200m 2.5km 150 km etc. instead of 1.2342356 m or 108.93837756 km. I would like for the step size to increase by 10m for the first 200m, then maybe by 50m up to 500m, then when passing the 1000 m value, it starts to deal with Kilometers, so then it is step size = 1 km up until 50 km, then maybe 25 km steps etc. Any way I go about this I end up doing a lot of rounding and a lot of calculations wrapped in a forrest of if statements and NSString/Number conversions, each time the user moves the slider just a little. I was hoping someone could lend me a bit of inspiration/math help or make me aware of a more lean approach to solving this problem. My last idea is to populate and array with a 100 string values, then have the slider int value correspond to a string, this is not very flexible, but doable. Thank you in advance for any help given:)

  • Height of tableHeaderView seems to be 0

    - by gabac
    I tried to override the second tableHeaderView. But it seems that the height of it in the method heightForHeaderInSection seems to be 0. Can't explain it, do I have to put it in a iVar because in the viewForHeaderInSection I can set the view without any problems. - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { if(section == 0) return @"Adding a new list"; else return @"Other lists"; } - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { if(section == 0) { return tableView.tableHeaderView; } else { UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(10, 10, 100, 50)] autorelease]; view.backgroundColor = [UIColor redColor]; return view; } } - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { if(section == 0) return tableView.tableHeaderView.frame.size.height; else return 30; }

  • Custom animation for pushing a UIViewController

    - by Heinrich
    Hi, I want to show a custom animation when pushing a view controller: I would like to achieve something like an "expand" animation, that means the new view expands from a given rectangle, lets say [100,100 220,380] during the animation to full screen. Any suggestions where to start, respectively any documents, tutorials, links? :) heinrich

  • Interface Builder caching bad data (voodoo)

    - by Ryan Townshend
    Sometimes IB will hold onto old or bad references, and I cannot seem to remove or edit them. EDIT I have made this a wiki question with the intention of gathering more data on the phenomenon. Answers involving situations where other coders have encountered this are welcome. This happened to me again last night with a table controller. When I created a spike project to try and reproduce the error, the system worked the way I anticipated. Then back in the actual project the bad behavior continued, even if I remove the xib file and all controllers involved. Creating a whole new project with none of the original (problematic) xib and nib files worked correctly. This question is not about the specifics of this incident but about this type of incident in IB. Does anyone know more about this type of bad IB behaviour, and possibly a more stylish way to to eliminate it than nuking the project? Note, removing the offending IB files and recreating them in the same project has not solved this for me in the past, only whole new projects. Answers regarding examples of when/how this glitch has been observed/created are welcome as well.

  • UIView, UIScrollView and UITextFields problem calling Method

    - by Jeff Groby
    I have a view with several embedded UITextFields, this UIView is subordinated to a UIScrollView in IB. Each text field is supposed to invoke a method called updateText defined in the viewcontroller implementation file when the user is done editing the field. For some reason, the method updateText never gets invoked. Anyone have any ideas how to go about fixing this? The method fired off just fine when the UIScrollView was not present in the project but the keyboard would cover the text fields during input, which was annoying. Now my textfields move up above the keyboard when it appears, but won't fire off the method when done editing. Here is my implementation file: #import "MileMarkerViewController.h" @implementation MileMarkerViewController @synthesize scrollView,milemarkerLogDate,milemarkerDesc,milemarkerOdobeg,milemarkerOdoend,milemarkerBusiness,milemarkerPersonal,milemarker; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Initialization code } return self; } - (BOOL) textFieldShouldReturn: (UITextField*) theTextField { return [theTextField resignFirstResponder]; } - (void)viewDidLoad { [super viewDidLoad]; [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWasShown:) name: UIKeyboardDidShowNotification object: nil]; [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWasHidden:) name: UIKeyboardDidHideNotification object: nil]; keyboardShown = NO; // 1 [scrollView setContentSize: CGSizeMake( 320, 480)]; // 2 } - (void)keyboardWasShown:(NSNotification*)aNotification { if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; // Get the size of the keyboard. NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; // Resize the scroll view (which is the root view of the window) CGRect viewFrame = [scrollView frame]; viewFrame.size.height -= keyboardSize.height; scrollView.frame = viewFrame; // Scroll the active text field into view. CGRect textFieldRect = [activeField frame]; [scrollView scrollRectToVisible:textFieldRect animated:YES]; keyboardShown = YES; } - (void)keyboardWasHidden:(NSNotification*)aNotification { NSDictionary* info = [aNotification userInfo]; // Get the size of the keyboard. NSValue* aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; // Reset the height of the scroll view to its original value CGRect viewFrame = [scrollView frame]; viewFrame.size.height += keyboardSize.height; [scrollView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES]; scrollView.frame = viewFrame; keyboardShown = NO; } - (void)textFieldDidBeginEditing:(UITextField *)textField { activeField = textField; } - (void)textFieldDidEndEditing:(UITextField *)textField { activeField = nil; } - (IBAction)updateText:(id) sender { NSLog(@"You just entered: %@",self.milemarkerLogDate.text); self.milemarker.logdate = self.milemarkerLogDate.text; self.milemarker.desc = self.milemarkerDesc.text; self.milemarker.odobeg = self.milemarkerOdobeg.text; self.milemarker.odoend = self.milemarkerOdoend.text; self.milemarker.business = self.milemarkerBusiness.text; self.milemarker.personal = self.milemarkerPersonal.text; NSLog(@"Original textfield is set to: %@",self.milemarker.logdate); [self.milemarker updateText]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)dealloc { [super dealloc]; } @end

  • Can't Reorder a UITableViewCell into _some_ empty sections of a UITableView

    - by Jeremy Lightsmith
    If I have a UITableView in edit mode, w/ reordering turned on, it seems I can't move some (but not all) cells into some (but not all) empty sections. For example, if I have this layout : Section 1 apple banana Section 2 doberman Section 3 Section 4 Then I can move 'doberman' into any slot in section 1 (except after 'banana'), but I can't move it into section 3 or 4 at all. On the other hand, I can move 'apple' & 'banana' into section section 2 (except after 'doberman'), and I CAN move it into section 3, but NOT into section 4. What gives? this seems like buggy behavior. How do people work around it? Is apple aware of this bug?

  • How can I write a scrolling text in cocos2d ?

    - by srikanth rongali
    I have a text and it should be abled to scrolled only up and down to see entire text. and my application is a game and written in cocos2d. So, I have layers. There is also an image(CCSprite) adjacent to text. The text should be scrolled and the image have a touchesEnded: property. I used CCLabel for text and CCParallaxNode to add the text. But the text appears like a continues paragraph. But, my text should have different lines. My text is like this. //text starts Hey Player. Do you want to play the game right now then play. Do you want to practice or Play? what want to do? ...text continues //text ends What should I use for this ? Thank you.

  • Cocoa Touch - Display an Activity Indicator while loading a UITabBar View

    - by Aurum Aquila
    I have a UITabBar Application with two views that load large amounts of data from the web in their "viewWillAppear" methods. I want to show a progress bar or an activity indicator while this data is being retrieved, to make sure the user knows the app isn't frozen. I am aware that this has been asked before. I simply need some clarification on what seems to be a rather good solution. I have implimented the code in the example. The question's original asker later solved their problem, by putting the retrieval of data into another "thread". I understand the concept of threads, but I do not know how I would impliment this. With research, I have found that I need to move all of my heavy data retrieval into a background thread, as all of the UI updating occurs in the main thread. If one would be so kind as to provide an example for me, I would be very appreciative. I can provide parts of my existing code as necessary.

  • How to get a reference to a control in the view?

    - by Kevin
    If I have a UIScrollView set up in the view via the Interface Builder, how do I get a reference to it in the ViewController implementation? I want to programmatically add labels to the scroll view. For example, in C# if you have a textbox declared in the UI/form, you can access it by simply using the ID declared for that textbox. It doesn't seem this simple in objective c. Thanks Kevin

  • How to manually throw a compiler error in GCC and Xcode

    - by coneybeare
    In xcode, while compiling apps with gcc, I want to throw compilation time errors if things like NSZombieEnabled is on for a distribution release, thus ensuring that compilation will fail and I won't accidentally do something stupid. I did some googling, but could not figure out how to cause the compiler to bail if a certain condition is met. Surely it must be easy, am I just not finding it?

  • IB not responding to UIImageView moving

    - by Rudiger
    This an incredibly annoying bug. I had a imageView and 2 Labels in a customCell nib. I changed the locations of all of them in the nib and the labels moved, view didn't. I've cleaned my targets, deleted everything relating to it the library, deleted the cell completely, reset the simulator, built it on a different target (3.1.2) and it still compiles the image in the same stupid spot. Can anyone help this is nuts. Sorry for being blunt but completely frustrated. Edit: I have deleted the nib and created it over again by hand, but with the same names. Doesn't fix it. I've checked to see if im moving it somewhere in the code and no dice.

  • Can I detect if higher subview has been touched?

    - by Kevin Beimers
    I've got a big UIView that responds to touches, and it's covered with lots of little UIViews that respond differently to touches. Is it possible to touch anywhere on screen and slide around, and have each view know if it's being touched? For example, I put my finger down on the upper left and slide toward the lower right. The touchesBegan/Moved is collected by the baseView. As I pass over itemView1, itemView2, and itemView3, control passes to them. If I lift my finger while over itemView2, it performs itemView2's touchesEnded method. If I lift my finger over none of the items, it performs baseView's touchesEnded. At the moment, if I touch down on baseView, touchEnded is always baseView and the higher itemViews are ignored. Any ideas?
