• The iPhone “phone” doesn’t have the provisioning profile with which the application was signed.

  - by eda

  i have tried everything to fix this provision problem and nothing is working. ive reformated my mac, reinstalled the iphone, ive also dragged the provisions (developer and distribution) onto the organizer, itunes, and xcode. in itunes people say to drag the provisions to the iphone icon but that doesnt work its only able to go under library it shows a blue rectangle for me to drop it there. i just have a newly created dummy app with a 57x57 icon. ive also setup the project with the distribution thing with its distribution provision. when i build i get this: The iPhone “myphone” doesn’t have the provisioning profile with which the application was signed. 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. I'm thinking its my problem whats it mean?

• Dragging an UIView inside UIScrollView

  - by Sergey Mikhanov

  Hello community! I am trying to solve a basic problem with drag and drop on iPhone. Here's my setup: I have a UIScrollView which has one large content subview (I'm able to scroll and zoom it) Content subview has several small tiles as subviews that should be dragged around inside it. My UIScrollView subclass has this method: - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { UIView *tile = [contentView pointInsideTiles:[self convertPoint:point toView:contentView] withEvent:event]; if (tile) { return tile; } else { return [super hitTest:point withEvent:event]; } } Content subview has this method: - (UIView *)pointInsideTiles:(CGPoint)point withEvent:(UIEvent *)event { for (TileView *tile in tiles) { if ([tile pointInside:[self convertPoint:point toView:tile] withEvent:event]) return tile; } return nil; } And tile view has this method: - (void)touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:self.superview]; self.center = location; } This works, but not fully correct: the tile sometimes "falls down" during the drag process. More precisely, it stops receiving touchesMoved: invocations, and scroll view starts scrolling instead. I noticed that this depends on the drag speed: the faster I drag, the quicker the tile "falls". Any ideas on how to keep the tile glued to the dragging finger? Thanks in advance!

  Hi, I have an android application that shows a grid view that shows: 1 2 3 4 GridView gridview=(GridView)findViewById(R.id.GridView_test); DataBaseHelper dbhelper=new DataBaseHelper(this); ArrayList<String> test=new ArrayList<String>(5); backlinksadapter.add("1"); backlinksadapter.add("2"); backlinksadapter.add("3"); backlinksadapter.add("4"); ArrayAdapter mAdapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, test); gridview.setAdapter(mAdapter); By the moment is working, but i would like to show foreach line of the grid, 2 columns with the values of a 2 dimensional array (something like the GridView in ASP.Net - as datasource -). I would like to show: 1 | Person 1 2 | Person 2 3 | Person 3 4 | Person 4 Any idea? Thanks in advance. Jose.

• Placement/Positioning/Alignment of UIScrollView w.r.t. length of Title NSString

  - by Shoaibi

  I have a scenario where i show stuff like: ----------------------------------- titleview (UITextView) ______________ tArea (UIScrollView) ttextview (UITextView) ----------------------------------- Now here is the condition: Length of titleview's text is dynamic, varies based on user input. Because of the condition I have trouble placing tArea e.g. UIScrollView on the screen, it either appears way too below than the titleview, or overlaps it. Previously what i did: Count the number of characters in titleview.text.length and divide them by 27 (e.g. characters in one line when using boldSystemFontOfSize:20) and multiply by 10 to get the starting X of tArea e.g. UIScrollView. But that sucked. Because i had to duplicate code for rotation to landscape. What do i have now? : CGSize titlesize = [title sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 90) lineBreakMode:UILineBreakModeWordWrap]; ttitleview = [[UITextView alloc] initWithFrame:CGRectMake(5, 5, 310,titlesize.height)]; ttitleview.text = title; ttitleview.font = [UIFont boldSystemFontOfSize:20]; ttitleview.backgroundColor = [UIColor clearColor]; ttitleview.editable = NO; [self.view addSubview:ttitleview]; CGSize textsize = [ttext sizeWithFont:[UIFont systemFontOfSize:20] constrainedToSize:CGSizeMake(5, 350) lineBreakMode:UILineBreakModeWordWrap]; tArea = [[UIScrollView alloc] initWithFrame:CGRectMake(5, titlesize.height, 310, 230)]; tArea.contentSize = CGSizeMake(310, textsize.height+20); tArea.pagingEnabled = FALSE; tArea.scrollEnabled = TRUE; tArea.backgroundColor = [UIColor clearColor]; [self.view addSubview:tArea]; ttextview = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 310, textsize.height + 20)]; ttextview.text = ttext; ttextview.font = [UIFont systemFontOfSize:20]; ttextview.backgroundColor = [UIColor clearColor]; ttextview.editable = NO; [tArea addSubview:ttextview]; But its no use. Looking for an elegant solution than this.

• iphone - passing an object on an UIToolbarButton action

  - by Mike

  Is that possible to make a UIToolbarButton pass an object to its target by using some exoteric method (as it seems not to be possible using regular button use)? I mean something like UIBarButtonItem *Button = [[UIBarButtonItem alloc] initWithImage:buttonImage style:UIBarButtonItemStylePlain target:self action:@selector(doSomething:) **withObject:usingThis**]; I know I can trigger a method that will launch the full method with the object, but for the sake of elegance I was trying to minimize the code... I suspect it is not possible, but as you guys out there are insanely good you may come with an transcendental answer... who knows...

• NSZombieEnabled hides EXC_BAD_ACCESS error entirely

  - by David Liu

  So I have a subclass of a UIView that starts causing EXC_BAD_ACCESS errors when I go through a specific set of conditions (run on iPad instead of iPhone or simulator, first login only). It throws the exception when the UIView subclass gets deallocated, during the last line, where I have [super dealloc]. I heard about using NSZombieEnabled, so I tossed that on to see if I could get any more information about it, but now it hides the error completely! Does anyone know a bit more about this type of situation? I thought NSZombie would start spewing stuff into my console like before, but I'm hoping that the nonexistance of errors would tell me some sort of information as well.

• Custom UINavigationBar Background

  - by tigermain

  I've been trying to set up a custom background for the whole of my NavigationBar (not just the titleView) but have been struggling. I found this thread http://discussions.apple.com/thread.jspa?threadID=1649012&tstart=0 But am not sure how to implement the code snippet that is given. Is the code implemented as a new class? Also where do I instatiate the NavigationController as I have an application built with the NavigationView template so it is not done in my root controller as per the example

• Keep object oriented towards a point while it's animated along a path

  - by Meltemi

  I'm trying to animate an object along a path...while it's moving it should continue to "point" towards another object (or CGPoint). What should I be looking for in the framework (Cocoa-Touch) to accomplish this? Maybe something in CAShapeLayer? Though I think that's more for animating the path itself... It's not jumping out at me...

• Core data setReturnsDistinctResult not working

  - by Moze

  So i'm building a small application, it uses core data database of ~25mb size with 4 entities. It's for bus timetables. In one table named "Stop" there are have ~1300 entries of bus stops with atributes "name", "id", "longitude", "latitude" and couple relationships. Now there are many stops with same name but different coordinates and id. Search is implemented using NSPredicate. So I want to show all distinct stop names in table view, i'm using setReturnsDistinctResults with NSDictionaryResultType and setPropertiesToFetch. But setReturnsDistinctResult is not working and I'm still getting all entries. Heres code: - (NSFetchRequest *)fetchRequest { if (fetchRequest == nil) { fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Stop" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; [fetchRequest setResultType:NSDictionaryResultType]; [fetchRequest setPropertiesToFetch:[NSArray arrayWithObject:[[entity propertiesByName] objectForKey:@"name"]]]; [fetchRequest setReturnsDistinctResults:YES]; DebugLog(@"fetchRequest initialized"); } return fetchRequest; } ///////////////////// - (NSFetchedResultsController *)fetchedResultsController { if (self.predicateString != nil) { self.predicate = [NSPredicate predicateWithFormat:@"name CONTAINS[cd] %@", self.predicateString]; [self.fetchRequest setPredicate:predicate]; } else { self.predicate = nil; [self.fetchRequest setPredicate:predicate]; } fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:self.fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:sectionNameKeyPath cacheName:nil]; return fetchedResultsController; } ////////////// - (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [[fetchedResultsController objectAtIndexPath:indexPath] valueForKey:@"name"]; return cell; }

• NSNotification center may not respond to -object ?

  - by blackkettle

  Hi, I'm trying to make simple use of the NSNotification center inside my iPhone application, but I seem to be doing something wrong in this case. I was under the impression that it was possible to retrieve an object associated with a particular message, or at least a reference to the object, but using the following example code I'm getting a warning, "NSNotification center may not respond to -object" - (void)addNewBookmark:(NSNotificationCenter *)notification { Bookmark *newBookMark = (Bookmark *)[notification object]; //Do some stuff with the bookmark object } Indeed, when I compile and run the code, basically nothing I try to do with the contents of the object actually gets carried out - it's simply ignored. The post code is as follows, - (IBAction)save:(id) sender{ //Sending the message with the related object [[NSNotificationCenter defaultCenter] postNotificationName:@"addNewBookmark" object:bookmark]; } and the bookmark object itself is just a dictionary. I also tried using the "userInfo" argument and passing the bookmark object through that, but the result was the same. How should I be doing this? What am I doing wrong?

• SIGABRT Issues with UIApplication_TVOut and MPVideoView - is there another way??

  - by user365920

  Hi there, I am due to do a demo in a week of an app which i have been working on for a company - until now, i have been using code taken from this useful tutorial here The problem is that this no longer seems to be working - causing a SIGABRT inside of the following (see initWithVideoView): - (void) startTVOut; { // you need to have a main window already open when you call start if (!tvoutWindow) { deviceWindow = [self keyWindow]; MPVideoView *vidView = [[MPVideoView alloc] initWithFrame: CGRectZero]; **tvoutWindow = [[MPTVOutWindow alloc] initWithVideoView:vidView];** [tvoutWindow makeKeyAndVisible]; tvoutWindow.userInteractionEnabled = NO; mirrorView = [[UIImageView alloc] initWithFrame: [[UIScreen mainScreen] bounds]]; [self reformatTVOutOrientation]; mirrorView.center = vidView.center; [vidView addSubview: mirrorView]; [deviceWindow makeKeyAndVisible]; [NSThread detachNewThreadSelector:@selector(updateLoop) toTarget:self withObject:nil]; } } Can anyone help at all??? This was all working fine, but seems to have stopped working recently - none of my code has changed, so assuming Apple have removed that API (yes, i know it was a private API in the first place, so im not moaning!) Just need to know if there is an alternative way of displaying the contents of my iPhone screen in my app... Many thanks in advance!

• Why I got some memory problems?

  I got this error from XCode: objc[8422]: FREED(id): message release sent to freed object=0x3b120c0 I googled and find that is related to the memory.

• Add Core Data Index to certain Attributes via migration

  - by steipete

  For performance reasons, i want to set the Indexed Attribute to some of my entities. I created a new core data model version to perform the changes. Core Data detects the changes and migrates my model to the new version, however, NO INDEXES ARE GENERATED. If I recreate the database from scratch, the indexes are there. I checked with SQLite Browser both on the iPhone and on the Simulator. The problem only occurs if a database in the prior format is already there. Is there a way to manually add the indexes? Write some sql for that? Or am I missing something? I did already some more critical migrations, no problems there. But those missing indexes are bugging me. Thanks for helping!

• Any way to trigger interface orientation check?

  - by Johnny Tee

  My app is going from a flipside view (only one orientation) to its main view (can have any sort of orientation. When I go from flipside back to main view, the main view's orientation is not checked and changed immediately. I need a way to trigger the built in orientation check that happens in willRotateToInterfaceOrientation so that the orientation is correct when the user goes from flipside view to main view. Any help is appreciated. I saw another question about this but didn't see a definitive answer. Thanks!

• Crashing when pushing a XIB based view controller onto navigation controller stack

  - by Michael

  I was attempting to clean up the implementation for a sub-panel on a navigation controller stack, so that the navigation bar could be customized in the XIB instead of doing it manually in the viewDidLoad method. The original (working) setup had the XIB set up with the "File's Owner" class set to the view controller class, and then the view at the top level. This works fine. In the "Interface Builder User Guide", p. 71, it describes the recommended way to build the XIBs for sub-panels ("additional navigation levels"). This approach leaves the "File's Owner" class as NSObject, but adds a UIViewController at the top level, and nests the view (and navigation item) underneath it. The UIViewController's view automatically gets connected to the contained view. When I try to push the controller init'd with this new XIB, the app crashes because of a missing view: SettingsViewController *controller = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; [self.navigationController pushViewController:controller animated:YES]; 2010-04-23 11:17:37.135 xxxx[1173:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsTestView" nib but the view outlet was not set.' I've double checked everything, and tried building a clean XIB from scratch, but get the same result. I looked through a number of the code sample projects, and NONE of them use the documented/recommended approach--they all use the File's Owner class and manually set up the navigation bar in viewDidLoad like I originally had it. Is it possible to get it working the "recommended" way? Thanks! Michael

• UIView frame origin doesn't set good

  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?

  I have a UINavigationController that is handling UITableViewController instances.

• Getting info from NSData object

  - by Moshe

  How would I get returningResponse (into say, a NSString) from the following code: NSURLResponse* response; NSError* error; NSData* result = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:&response error:&error]; I think I can get the info that I need into a string but I can't call anything on response because it's null. Therefore, I assume that I need to call something on result. The problem is, I don't know what to call. (The URL request has been coded prior to the code sample. I know that that works.) I want to be able to detect if the request as successful.
