  • How to get the same UITableViewCell layout as in the Address Book app?

    - by Romain
    Hi, I currently have a custom UITableViewCell which contains a few labels, and an image. The "main" label is used to display people's names. Currently, I'm styling it in bold text. What I'd like to do (to gain some space and readability), is to mimic the Address Book app cell style, that is: first name in light text, and family name in bold text. Is there a way to do this using the same UILabel? Or, should I use 2 different UILabels? How should I layout them, without knowing their sizes? Thanks in advance for your assistance!

  • UITableViewCellStyleValue2 edit indicators?

    - by Jason Jardim
    I am using this style of table view UITableViewCellStyleValue2. I set editing, but I cant seem to get the arrows to show up on the right of the cell - like the Contacts app. Also in the contacts app I notice that if I have a Favorite it puts a * (star) to the right. Any info on how to get an image would be appreciated. Thanks!

  • AVAudioPlayer making noise when playing multiple sounds at the same time

    - by Rob
    I am having an issue where AVAudioPlayer is introducing noise into playback ONLY when I play multiple sound files at the same time. If I play them each individually, they all sound perfect. But, if I play sound clip B while sound clip A is still playing, the speakers start crackling like there is noise. I have tried both m4a files AND caf files and both make the same noise, so it has to be something with how I am implementing this method or a quirk with AVAudioPlayer. Any insights? code I am using: UITouch* touch = [[event allTouches] anyObject]; NSString* filename = [soundArray objectAtIndex:[touch view].tag]; NSString *path = [[NSBundle mainBundle] pathForResource:filename ofType:@"m4a"]; AVAudioPlayer * newAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; self.theAudio = newAudio; // automatically retain audio and dealloc old file if new m4a file is loaded [newAudio release]; // release the audio safely theAudio.delegate = self; [theAudio prepareToPlay]; [theAudio setNumberOfLoops:0]; [theAudio setVolume: volumeLevel]; [theAudio play];

  • How to conform to UITabBarControllerDelegate

    - by 4thSpace
    I have a tabbar based application and do the following to get a reference to the application delegate: MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; Which then gives this warning: warning: type 'id <UIApplicationDelegate>' does not conform to the 'UITabBarControllerDelegate' My application delegate header looks like this: #import <UIKit/UIKit.h> @interface MyAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; @end The only methods in the .m file are applicationDidFinishLaunching and dealloc. What else do I need to conform to the protocol?

  • First Tap on customcell of uitableview should expand it and second should contract it.

    - by neha
    Hi all, In my application I have this requirement that first tap on custom cell of uitableview with a label in it should expand it and second should contract it. I'm able to expand and contract cell and expand label inside cell, but not able to contract the label on second tap. I'm using this function - (void)setSelected:(BOOL)selected animated:(BOOL)animated { [super setSelected:selected animated:animated]; if( selected == YES ) { [self expandRow]; } else { [self contractRow]; } height = [lblFeed frame].size.height + 75; } expandRow expands the label and contractRow contracts it. I'm perplexed as for how many rows this function gets called. It doesn't get called only for the cell tapped, it gets called more number of times for single tap on single cell may be for other cells but I'm not getting which rows. This' really urgent. Can anybody please help?

  • iPhone: Utility Application - Open Flipside on startup

    - by Joel
    I have an application that I started with the Utility Application template. I'm using the Flipside for the Settings screen. I'm having the settings serialized to a file when the app is closed and deserialized when the app is opened. If there is no file to deserialize at startup, I want the flipside to be shown so the user can enter required information. This is what I have: - (void)viewDidLoad { flipController = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; flipController.delegate = self; flipController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; if(![self deserialize]) { [self showInfo]; } } - (IBAction)showInfo { [self presentModalViewController:flipController animated:YES]; } showInfo is the method that is called with the little 'i' button is pressed on the MainView. The button works, however my call in viewDidLoad doesn't. I have run through my code with the debugger. [self deserialize] is returning NO and [self showInfo] is being called, and I checked if flipController is nil in that context, and it's not. I've searched around and couldn't find anyone who's tried to do the same thing. I'm stumped to as why this isn't working. Anyone see what I'm doing wrong? Thanks

  • What is the delegate method that is called when an MKPinAnnotationView is touched?

    - by Jake Schwartz
    I have been searching for this all night and I have just so frustrated. When a MKPinAnnotationView is clicked, the name and the subtitle comes up. I also want to center that point on the view. I figured there was some method I had to override because the information that pops up happened without me having to code it. Hopefully this was clear enough for you all. And in the mean time, I feel like there is some hidden guide on this use of MKMaps and other classes. Either that or it is terribly documented because I am having a lot of trouble finding information. Thanks.

  • Objective C: Create arrays from first array based on value

    - by Nic Hubbard
    I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

  • Dragging a Sprite (Cocos2D) while Chipmunk is simulating

    - by itai alter
    Hello all! I have a simple project built with Cocos2D and Chipmunk. So far it's just a Ball (body, shape & sprite) bouncing on the Ground (a static line segment at the bottom of the screen). I implemented the ccTouchesBegan/Moved/Ended methods to drag the ball around. I've tried both: cpBodySlew(ballBody, touchPoint, 1.0/60.0f); and ballBody->p = cgPointMake(touchPoint.x,touchPoint.y); and while the Ball does follow my dragging, it's still being affected by gravity and it tries to go down (which causes velocity problems and others). Does anyone know of the preferred way to Drag an active Body while the physics simulation is going on? Do I need somehow to stop the simulation and turn it back on afterwards? Thanks!

  • Nav Controller, UITableViewController, UITextField to become firstResponder?

    - by Daniel Granger
    I have a core data application which uses a navigation controller to drill down to a detail view and then if you edit one of the rows of data in the detail view you get taken to an Edit View for the that single line, like in Apples CoreDataBooks example! The edit view is a UITableviewController which creates its table with a single section single row and a UITextfield in the cell, programatically. What I want to happen is when you select a row to edit and the edit view is pushed onto the nav stack and the edit view is animated moving across the screen, I want the textfield to be selected as firstResponder so that the keyboard is already showing as the view moves across the screen to take position. Like in the Contacts app or in the CoreDataBooks App. I currently have the following code in my app which causes the view to load and then you see the keyboard appear (which isn't what I want, I want the keyboard to already be there) - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [theTextField becomeFirstResponder]; } You can't put this in -viewWillAppear as the textfield hasn't been created yet so theTextField is nil. In the CoreDataBooks App where they achieve what i want they load there tableview from a nib so they use the same code but in -viewWillAppear as the textfield has already been created! Is there anyway of getting around this without creating a nib, I want to keep the implementation programatic to enable greater flexibility. Many Thanks

  • Allowing user to select a UIPickerView row by tapping.

    - by camilo
    Hi. I'm trying to use a UIPicker View with a behavior somehow different of what's usually seen in iPhone code examples. What I want to do is to allow users to scroll through the picker contents, but not to select a picker's row automatically (using the "didSelectRow" method from picker's delegate). Instead, I want to allow the user to touch the center row of the picker, which gets highlighted, and becomes the selection. Is there any way to achieve this? Thanks in advance.

  • Remove In-App Purchase from free app and increase the price

    - by Arseniy Banayev
    The current version of an application in the App Store is free and has very limited functionality. An In-App Purchase unlocks everything else. I have decided to remove the In-App Purchase and just make the application cost the same price as the In-App Purchase did. But if I make the update now, then those users who have the free version but who have not yet paid for the In-App Purchase will get a free update into the full version. I have removed all traces of my singleton class, PurchaseManager, from the application, so that at this point, when I build/run it, all of the features are unlocked. At this point, how can I make sure that the free-version users don't just ride an update into the full version? Maybe there's a way to test whether the app is obtained through an update or through a purchase? That way, if it's through an update, I will see if it's the free version w/o the IAP and then force the user to purchase the IAP to continue playing. Any ideas?

  • iPhone Table View Cell Image: Working on simulator, not showing on real device

    - by Graeme
    Hi, I have a UITable View that displays an image in the left hand side of the table cell, and it works fine in the simulator. Only problem is, once I ran it on my device no images appear. At first 3 did, but then I "cleaned headers" and now none appear. Have checked that images are added to resource folder for build (which they are) and that capitals etc. match (which they do). Any ideas? Thanks. Code to display images: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[dog types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; }
