  • TabBars and iOS 7

    - by MichaelScaria
    I have a UITabbarController that I'm pushing another controller on top of using a UINavigationController. On iOS 6 and below, the tabBar of the parent controller slides away and the toolbar of the new view controller is presented. But on iOS 7 the tabBar doesn't animate away even if I run the code [self.navigationController setToolbarHidden:YES animated:NO]; EDIT - Okay I narrowed my problem to iOS 7 not respecting the hidesBottomBarWhenPushed property, I followed the answers in hidesBottomBarWhenPushed ignored in iOS 7 but it didn't work. The view that is pushed has a toolbar with buttons and the buttons are responding to touches, it's just that the tabBar is on top of the toolbar.

  • when to use "willChangeValueForKey" and "didChangeValueForKey"?

    - by Frost Li
    I saw these lines in a demo project, but I couldn't understand why it did that. [self willChangeValueForKey:@"names"]; [self didChangeValueForKey:@"names"]; It called didChangeValueForKey immediately after willChangeeValueForKey. Does it make any sense? Furthermore, when should be the right time to call this two methods? Thanks a lot!! :)

  • The delegate method "clickedButtonAtIndex:" is not called.

    - by sagiftw
    Hello everyone! I have created an alert view with two buttons using the following code: UIAlertView *alertView = [[UIAlertView alloc] initWithTitle: title message: msg delegate:nil cancelButtonTitle:@"Replay" otherButtonTitles:@"Highscore", nil]; [alertView show]; I want to run some code when one of the buttons is clicked. In order to do so, I have added the following method to the delegate.m file: - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex==0) //Run some code else //Other code } But this method is not called when I press either of the buttons! Can someone tell me why? Thanks in advance, Sagiftw

  • How to do something when AVQueuePlayer finishes the last playeritem

    - by user1634529
    I've got an AVQueuePlayer which I'm creating from an array of 4 AVPlayerItems, and it all plays fine. I want to do something when the last item in the queue finishes playing, I've looked a load of answers on here and this is the one that looks most promising for what I want: The best way to execute code AFTER a sound has finished playing In my button handler i have this code: static const NSString *ItemStatusContext; [thePlayerItemA addObserver:self forKeyPath:@"status" options:0 context:&ItemStatusContext]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerItemDidReachEnd) name:AVPlayerItemDidPlayToEndTimeNotification object:thePlayerItemA]; theQueuePlayer = [AVQueuePlayer playerWithPlayerItem:thePlayerItemA]; [theQueuePlayer play]; and then I have a function to handle playerItemDidReachEnd: - (void)playerItemDidReachEnd:(NSNotification *)notification { // Do stuff here NSLog(@"IT REACHED THE END"); } But when I run this I get an Internal Inconsistency Exception: An -observeValueForKeyPath:ofObject:change:context: message was received but not handled. Key path: status Observed object: <AVPlayerItem: 0x735a130, asset = <AVURLAsset: 0x73559c0, URL = file://localhost/Users/mike/Library/Application%20Support/iPhone%20Simulator/5.0/Applications/A0DBEC13-2DA6-4887-B29D-B43A78E173B8/Phonics%2001.app/yes.mp3>> Change: { kind = 1; } What am I doing wrong?

  • What happens inside the try block?

    - by dontWatchMyProfile
    Example: @try { // 1) do bad stuff that can throw an exception... // 2) do some more stuff // 3) ...and more... } @catch (NSException *e) { NSLog(@"Error: %@: %@", [e name], [e reason]); } If 1) throws an exception, is the block immediately canceled like a return in a function or a break in a loop? Or will 2) and 3) be processed no matter what happens in 1)?

  • Can't give my custom prototype cells in tableview different heights

    - by kerbelda
    I've looked around at other questions here and many other sources online and just can't find a solution. I have 3 rows and no matter what I do, they all keep the width defined in the tableview. The first one is what I want, but the second and 3rd I can't give a custom height. Below is my code: #import "DetailTableViewController.h" #import "EventDetailTableViewCell.h" #import "EventDescriptionTableViewCell.h" #import "EventMapTableViewCell.h" @interface DetailTableViewController () @end @implementation DetailTableViewController - (void)viewDidLoad { [super viewDidLoad]; } #pragma mark - Table view data source - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // Return the number of sections. return 3; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // Return the number of rows in the section. return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.section == 0) { static NSString *CellIdentifier = @"headerCell"; EventDetailTableViewCell *headerCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; headerCell.headerImage.image = [UIImage imageNamed:@"img4.png"]; return headerCell; } else if (indexPath.section == 1) { static NSString *CellIdentifier = @"descriptionCell"; EventDescriptionTableViewCell *descriptionCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; descriptionCell.descriptionImage.image = [UIImage imageNamed:@"img2.png"]; return descriptionCell; } else { static NSString *CellIdentifier = @"mapCell"; EventMapTableViewCell *mapCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; return mapCell; } } #pragma mark - Helper Methods - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { if (section == 1) { return @" "; } else if (section == 2) { return @" "; } else { return nil; } } -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.row == 0) { return 222; } else if (indexPath.row == 1) { return 80; } else { return 100; } } @end

  • Retrieving Data in A NSTableView

    - by Heisennberg
    I have a three column Table View populated by two NSMutableDictionaries which share the same keys (ie key | value1 | value2 ) with dict1(key,value1) and dict2(key,value2). I want to manually enter data in the third column and create the key/value objects in dict2. But when I do that, my code picks the wrong key :S Here's the code for the delegate : - (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { if ([[aTableColumn identifier] isEqualToString:@"value2"]) { [dict2 setValue:anObject forKey:[[[aTableView tableColumnWithIdentifier:@"key"] dataCellForRow:rowIndex] stringValue ]]; } } Any idea ?

  • iPad search bar bad memory access?

    - by Geoff Baum
    Hello all, So I am trying to implement a search bar in my app and am very close but can't seem to figure out where this memory error is occurring. This is what part of my search method looks like: filters = [[NSMutableArray alloc] init]; NSString *searchText = detailSearch.text; NSMutableArray *searchArray = [[NSMutableArray alloc] init]; // Normally holds the object (ex: 70 locations) searchArray = self.copyOfFilters ; //This is the line that is breaking after ~2-3 letters are entered in the search for (NSString *sTemp in searchArray) { NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch]; if (titleResultsRange.length > 0) [filters addObject:sTemp]; } displayedFilters = filters; copyOfFilters is a deep copy of the displayed filters that appear when the view first loads via: self.copyOfFilters = [[NSMutableArray alloc] initWithArray:displayedFilters copyItems:YES]; I have traced through the entry of letters and it is accurate after 2 letters, but once you try and enter a letter after a space in the search bar, it crashes. The value of copyOfFilters = {(int)[$VAR count]} objects. Does anyone know what may be causing this? Thanks!

  • remove 2 subviews in one go.

    - by Pavan
    hi, I am trying to remove two viewcontrollers (that have been added on top of each other) with one method. I have made the views in interfacebuilder. they all have their own .h and .m files to go with it. Scenario I am in: I have a main menu which has the view2 header file imported. In a method I add the second view on top of the superview like so view2ViewController * view2 = [[view2ViewController alloc] initWithNibName:@"view2ViewController" bundle:nil]; [self.view addSubview:view2.view]; then in view 2 I have added the view 3 header file so i can add view 3 as a subview ontop of view2. i have another method which is connected again to interface builder to a UIButton so upon button press a method gets called in view2 which adds view 3 on top in exactly the same way like so: view3ViewController * view3 = [[view3ViewController alloc] initWithNibName:@"view3ViewController" bundle:nil]; [self.view addSubview:view3.view]; What im trying to solve: I have a button in view 3 which should remove view 3.... and then it should also remove view 2 aswell so the main screen is visible. How can this be achieved? What I have so far: [self.view removeFromSuperview]; This however only removes View 3... but leaves view 2 in place. What needs to be modified so that i can remove view 2 as well?? Any help is appreciated.

  • Getting Values from fetched Core Data

    - by user571905
    Hi there, Thanks to the wonderful people on this forum, I have overcome most of my Core Data woes. However one persists, and I'm certain it is a simple fix. I have a recipe app that parses an XML doc on load and puts the data in Core Data. Then I search that Core Data for particular recipes, ingredients, etc. Everything is working with one exception... I cannot do anything with the data I retrieve. For example, I search the core data for "eggplant" and get this at the end of the process: "<RecipeData: 0x6112a40> (entity: RecipeData; id: 0x6113880 <x-coredata:///RecipeData/tCDE9A0EE-DA3F-4BD0-AEF8-3C038586991D4> ; data: {\n ingredients = \"Eggplant|Cheese|Tomatoes|\";\n name = \"Eggplant Parm\";\n time = 40;\n})" How do I get the info out of there? I tried looping through, but that causes the app to crash: for (NSString* key in selectedRecipe) { id value = [selectedRecipe objectForKey:key]; NSLog(@"IN LOOP: %@", value); } Any suggestions? Thank you for your time.

  • MKMapView maptype not changing!

    - by TheLearner
    I cannot understand why my MKMapView does not want to change to satellite view. This method is called and case 1 is called I have stepped over it but it simply does not change to satellite type it always changes to standard. It only works when it goes back to Map type. Anyone have any ideas? - (IBAction)mapSatelliteSegmentControlTapped:(UISegmentedControl *)sender { switch (sender.selectedSegmentIndex) { case 1: //Satellite self.mapView.mapType = MKMapTypeSatellite; default: //Map self.mapView.mapType = MKMapTypeStandard; } }
