  • iPhone SDK audioSession question.

    - by Morion
    Hi to all. In my app i record and play audio at the same time. The app is almost finished. But there is one thing, that annoying me. When audio session is set to PlayAndRecord, sounds become quiet in comparison with the same sounds with the SoloAmbient category. Is there any way to make sound louder using PlayAndRecord?

  • Draw a cross at center of a UIImagePickerController.

    - by VansFannel
    Hello. I'm very new on iPhone development. I'm trying to draw a cross over the image obtained from camera. I'm using a custom ViewController that inherits from UIImagePickerController. When I star the application, I see the cross, but a few seconds after the cross disappears. Should I use cameraOverlayView? Thank you

  • UITabBarController "More" tab issues

    - by codemonkey
    I've got a UITabBarController with 7 tabs. Each of the 7 tabs has its own UINavigationController and customizes its toolbar. When a view is loaded via the UITabBarController's "More" menu its custom toolbar isn't appearing. If i switch the order of the views around so that the same view is now accessible from the UITabBar without going through the "More" menu then the custom toolbar shows up like it's supposed to. Is there a way to customize a NavigationController's toolbar when that NavigationController is loaded via the "More" menu of a TabBarController? I'm actually also interested in replacing the "More" menu navigation controller with my own custom one on views loaded via the "More" menu... not sure whether that's even possible. Any feedback will be appreciated.

  • IPhone memory problems...

    - by jAmi
    Hi, I am working on an App that is already been made but Memory Management was not considered in the development stages. So what can I do to keep the App memory usage low as soon as I get a memory warning? Is there any general tool or some piece of code that I can use to release any unused memory?

  • Navigation Items in Navigation Bar are not appearing?

    - by Sheehan Alam
    I am displaying a UITableViewController inside of a UITabBarController that is being presented modally: -(IBAction)arButtonClicked:(id)sender{ ARViewController* arViewController = [[[ARViewController alloc] initWithNibName:@"ARViewController" bundle:nil]autorelease]; LeaderBoardTableViewController* lbViewController = [[[LeaderBoardTableViewController alloc] initWithNibName:@"LeaderBoardTableViewController" bundle:nil]autorelease]; lbViewController.title = @"Leaderboard"; arTabBarController = [[UITabBarController alloc] initWithNibName:nil bundle:nil]; arTabBarController.viewControllers = [NSArray arrayWithObjects:arViewController, lbViewController, nil]; arTabBarController.selectedViewController = arViewController; [self presentModalViewController:arTabBarController animated:YES]; } In my viewDidLoad for arViewController method I am setting the navigation items: - (void)viewDidLoad { [super viewDidLoad]; // Uncomment the following line to preserve selection between presentations. self.clearsSelectionOnViewWillAppear = NO; self.title = @"AR"; leaderBoardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemOrganize target:self action:@selector(leaderBoardButtonClicked:)]; self.navigationItem.rightBarButtonItem = leaderBoardButton; } My navigation bar doesn't appear when it is inside of the UITabBarController, but when I push the view itself I am able to see it. What am I missing?

  • Mac OS X Status Bar Application - Hiding it from Cmd/Alt menu?

    - by Moddy
    I'm trying to whip up a simple little Status Bar Application in Obj-C/Cocoa. So I have done it pragmatically - declaring an NSStatusItem, adding it to the NSStatusBar and then giving it a NSMenu object. A bit like this... NSStatusBar *bar = [NSStatusBar systemStatusBar]; theItem = [bar statusItemWithLength:NSVariableStatusItemLength]; [theItem retain]; [theItem setTitle: NSLocalizedString(@"Tablet",@"")]; [theItem setHighlightMode:YES]; [theItem setMenu:theMenu]; (Example taken from "Status Bar Programming Topics", Apple Documentation) Now ideally, I'd like this application to run and not be accessible from the CMD/ALT window changing "menu" (for lack of a better word), I've seen applications do it before and would like that really. The idea is I just want it to be accessible from every window, whilst not having its own NSMenu on the status bar, and whilst not being able to have it as the active application ( - so its not able to take over the whole Status Bar, and its not able to be seen through CMD/ALT) Additionally, I was wondering if the StatusBarItem supports the ability to drag-n-drop an item onto it? I'm not sure if thats a limitation of the NSStatusBar though. I've read up on deamons and agents, but that seems far too low level/over kill for such a simplistic app! Cheers in advance!

  • selecting a row by means of a button ... using didSelectRowAtIndexPath

    - by John Smith
    hey people , I have a question concerning a button I would like to create which selects my previous selected row. This is what I came up so far but since I'm new with the functionality and such I could definately use some pointers I created a toolbar with a button and behind this button is the following action. -(void)clickRow { selectedRow = [self.tableView indexPathForSelectedRow]; [self.tableView:[self tableView] didSelectRowAtIndexPath:selectedRow]; } in my didSelectRowAtIndexPath there is a rootViewController being pushed rvController = [RootViewController alloc] ...etc So what I would like is my function clickRow to select the row and push the new rootviewcontroller (which has the right info since I'm using a tree ). I tried something like this as well -(void)clickRow { NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; NSArray *Children = [dictionary objectForKey:@"Children"]; rvController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]]; rvController.CurrentLevel += 1; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } The last function works a little but a little is not enough;) For instance if I press the middle row or any other it constantly selects the toprow. thnx all for those of you reading and trying to help

  • Test iPhone in-app purchases on a different bundle?

    - by Andrew Johnson
    We have a group of beta testers for iPhone app. Recently, we added in-app purchases to the app. Before this, we would send out ad hoc builds to beta testers using a separate bundle ID and name so that they could have the store build and the ad hoc build on their phones. However, it seems like we have to build the ad hoc copy with the same Bundle ID to test in-app purchases, and this means we can't send out a seperate beta copy - our beta file (annoyingly) overwrites the user's store-bought app. Is there any way to test in-app purchases in a different bundle ID? Do I need to set up fake, test in-app purchases for the test build too?

  • addObjectsFromArray

    - by derek.lo
    I have a question about memory management when using the addObjectsFromArray method. Basically, I have 2 arrays defined in the appDelegate. I need these 2 arrays for the duration of my application's runtime. I therefore release them in my appDelegate's dealloc method. When I go to use these two arrays in a class, I want one array to store the values from the other, so that the other can have it's contents removed, but still stick around for use. Something like this: [appDelegate.arrayTwo addObjectsFromArray:appDelegate.arrayOne]; [appDelegate.arrayOne removeAllObjects]; I'm getting the compiler error: EXC_BAD_ACCESS because of a pointer issue? retaining issue? Any help would be greatly appreciated! Thanks

  • Where to #include?

    - by fuzzygoat
    In my past applications I have been #importing into my *.h files where needed. I have not really thought much about this before as I have not had any problems, but today I spotted something that got me to thinking that maybe I should be #import-ing into my .m files and using @class where needed in the headers (.h) Can anyone shine any light on the way its supposed to be done or best practice? gary

  • How to convert code to properly release memory

    - by BankStrong
    I've taken over a code base that has subtle flaws - audio player goes mute, unlogged crashes, odd behavior, etc. I found a way to provoke one instance of the problem and tracked it to this code snippet: NSURL *soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[[soundsToPlay objectAtIndex:count] description] ofType:@"mp3"]]; self.audioPlayer = nil; self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:nil]; self.audioPlayer.delegate = self; AudioSessionSetActive(YES); [audioPlayer play]; When I comment out the 2nd line (nil) and add a release to the end, this problem stops. [self.audioPlayer release]; Where do I go from here? Nils are used in a similar fashion throughout the code (and may cause similar problems) - is there a safe way to remove them? I'm new to memory management - how can I discern proper nil usage from bad nil usage?

  • iphone NSMutableArray loses objects at end of method

    - by Brodie4598
    Hello - in my app, an NSMutableArray is populated with an object in viewDidLoad (eventually there will be many objects but I'm just doing one til I get it working right). I also start a timer that starts a method that needs to access the NSMutableArray every few seconds. The NSMutableArray works fine in viewDidLoad, but as soon as that method is finished, it loses the object. myApp.h @interface MyApp : UIViewController { NSMutableArray *myMutableArray; NSTimer *timer; } @property (nonatomic, retain) NSMutableArray *myMutableArray; @property (nonatomic, retain) NSTimer *timer; @end myApp.m #import "MyApp.h" @implementation MyApp @synthesize myMutableArray; - (void) viewDidLoad { cycleTimer = [NSTimer scheduledTimerWithTimeInterval:4.0 target:self selector:@selector(newCycle) userInfo: nil repeats:YES]; MyObject *myCustomUIViewObject = [[MyObject alloc]init]; [myMutableArray addObject:myCustomUIViewObject]; [myCustomUIViewObject release]; NSLog(@"%i",[myMutableArray count]); /////outputs "1" } -(void) newCycle { NSLog(@"%i",[myMutableArray count]); /////outputs "0" ?? why is this?? }

  • How to properly set relationships in Core Data when using setValue and data already exists

    - by ern
    Let's say I have two objects: Articles and Categories. For the sake of this example all relevant categories have already been added to the data store. When looping through data that holds edits for articles, there is category relationship information that needs to be saved. I was planning on using the -setValue method in the Article class in order to set the relationships like so: - (void)setValue:(id)value forUndefinedKey:(NSString *)key { if([key isEqualToString:@"categories"]){ NSLog(@"trying to set categories..."); } } The problem is that value isn't a Category, it is just a string (or array of strings) holding the title of a category. I could certainly do a lookup within this method for each category and assign it, but that seems inefficient when processing a whole bunch of articles at once. Another option is to populate an array of all possible categories and just filter, but my question is where to store that array? Should it be a class method on Article? Is there a way to pass in additional data to the -setValue method? Is there another, better option for setting the relationship I'm not thinking of? Thanks for your help.

  • @property, setter and getter question?

    - by fuzzygoat
    NSString *statusValue; NSString *currentValue; @property(retain, nonatomic) NSString *statusValue; @property(retain, nonatomic) NSString *currentValue; @synthesize statusValue; @sythnesize currentValue; Given the above, if I am setting one variable to another is it work doing ... [self setStatusValue: currentValue]; or should I use the property again and use [self setStatusValue: [self currentValue]]; I suppose the latter (although maybe overkill) does tell the reader that we are using one of the objects instance variables and not some local variable. just curious really ... gary
