  • applicaion and local service lifetime

    - by rayman
    As i understoond, if we have local service of some application, as soon as the application goes down, the service goes down as well - is that true? and if it is, how can we make an application to run all the time without go down? (without using Alarm manager). i though that the purpose of local service is to answer this situation: " to make the application everlasting" please, if some1 could explain me this better, thanks, ray.

    - by srikanth rongali
    Hi, I need some information about using cocos2d in iPad. Can we use 2048x2048 sprite sheets ? I read in this form that we can use but with limitation not more than 3 or 4 sprite sheets. But, I have 10 animations in my game. maximum of 4 animations run at a time. Can we use the CCDirectors in AppDelegate in the same way as we use in iPhone ? if( ! [CCDirector setDirectorType:CCDirectorTypeDisplayLink] ) [CCDirector setDirectorType:CCDirectorTypeDefault]; [[CCDirector sharedDirector] setPixelFormat:kPixelFormatRGBA8888]; [CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888]; What can be the maximum size of the image that we can use?

  • iPhone - cannot run code on device

    - by lostInTransit
    Hi I have some source code which I had developed and later gave to another team. They signed it with their certificate and provisioning profile. Now I have the code back and have set the appropriate values in the project properties for code signing identity (with my cert and profile). But when I run the application on a device, I get an error showing the other team's certificate and prompting that the provisioning profile does not exist. I don't know where it is being referenced. Can someone please help. Thanks.

  • Reading Images only from Camera

    - by Ankit
    I wanted to read images only from the Camera folder of the device. Since the folder might be different for different devices, how can I write a simple application for it). So far I have written the following code, which does read from Camera folder, but it also reads from other places on sdcard as well. Cursor childCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, MediaStore.Images.ImageColumns._ID, null); do { ImageView image = new ImageView(); image.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ childCursor.getString( childCursor.getColumnIndex( MediaStore.Images.ImageColumns._ID ))); <some other code> } while (childCursor.moveToNext()); How can I create a generic app and filter on Camera Images before displaying. Any help is appreciated.

  • Best point to overwrite the navigationBar property of navigationController

    - by flohei
    Hi there, I'm overwriting UINavigationController to replace the default navigationBar property with an instance of my own subclass of UINavigationBar. So I tried something like _navigationBar = [[SBNavigationBar alloc] init]; in my -initWithRootViewController:. But that didn't work out as I expected it. There's still the default navigationBar being displayed. So what's the best point to overwrite the navigationBar? Thanks in advance –f

  • Giving another object a NSManagedObject

    - by Wayfarer
    Alright, so I'm running into an issue with my code. What I have done is subclassed UIButton so I can give it some more infomormation that pertain to my code. I have been able to create the buttons and they work great. Capiche. However, one of the things I want my subclass to hold is a reference to a NSMangedObject. I have this code in my header file: @interface ButtonSubclass : UIButton { NSManagedObjectContext *context; NSManagedObject *player; } @property (nonatomic, retain) NSManagedObject *player; @property (nonatomic, retain) NSManagedObjectContext *context; - (id)initWithFrame:(CGRect)frame andTitle:(NSString*)title; //- (void)setPlayer:(NSManagedObject *)aPlayer; @end As you can see, it has a instance variable to the NSMangedobject I want it to hold (as well as the Context). But for the life of me, I can't get it to hold that NSManagedObject. I run both the @synthesize methods in the Implementation file. @synthesize context; @synthesize player; So I'm not sure what I'm doing wrong. This is how I create my button: ButtonSubclass *playerButton = [[ButtonSubclass alloc] initWithFrame:frame andTitle:@"20"]; //works playerButton.context = self.context; //works playerButton.player = [players objectAtIndex:i]; //FAILS And I have initilaized the players array earlier, where I get the objects. Another weird thing is that when it gets to this spot in the code, the app crashes (woot) and the the console output stops. It doesn't give me any error, and notification at all that the app has crashed. It just... stops. So I don't even know what the error is that is crashing the code, besides it has to do with that line up there setting the "player" variable. Thoughts and ideas? I'd love your wisdom!

  • UIButton only responds in a small area

    - by Tom Irving
    I'm trying to add a UIButton to a UIView, but am having some trouble with getting it to respond to touches. I have a method which returns UIButtons after I provide it with a tag: - (UIButton*)niceSizeButtonWithTag:(int)tag { UIButton * aButton = [UIButton buttonWithType:UIButtonTypeCustom]; [aButton setTag:tag]; [aButton addTarget:self action:@selector(buttonWasTapped:) forControlEvents:UIControlEventTouchUpInside]; CGRect newFrame = aButton.frame; newFrame.size.width = 44; newFrame.size.height = 44; [aButton setFrame:newFrame]; return aButton; } As you can see I'm creating a new button and increasing the size. I use this in the following way: UIButton * anotherButton = [self niceSizeButtonWithTag:1]; [anotherButton setImage:[UIImage imageNamed:@"image" withExtension:@"png"] forState:UIControlStateNormal]; [anotherButton setCenter:CGPointMake(middleOfView)]; [aView addSubview:anotherButton]; I create a lot of buttons like this, hence the reason for the method. The buttons are always created and added to the subview perfectly. I can see the image and they're in the correct position. The problem is that they only respond to touches in a tiny strip. In this attached image, The yellow shows the whole frame of the button, The red shows the area that will respond to touches. The grey shows a section of the view the button is added to. If anyone could shed some light on why this is happening, it would be really useful.

  • iPhone: Use a view as a transparent overlay with closing button

    - by axooh
    I've got a map with three bar buttons for different markers to show up in the map. If I click on a bar button, the specific markers are shown in the map, which already works great. Now I would like to show a transparent overlay (popup window) with the description of the markers after I clicked on a bar button with a button to close the overlay again and show the markers (which are set in the background). The function of the bar button: - (IBAction)routeTwo:(id)sender { // The code for the overlay // ... // remove any annotations that exist [map removeAnnotations:map.annotations]; // Add any annotations which belongs to route 2 [map addAnnotation:[self.mapAnnotations objectAtIndex:2]]; [map addAnnotation:[self.mapAnnotations objectAtIndex:3]]; [map addAnnotation:[self.mapAnnotations objectAtIndex:4]]; [map addAnnotation:[self.mapAnnotations objectAtIndex:5]]; } I tried the following possibilities: 1. Using a modal view controller RouteDescriptionViewController *routeDescriptionView = [[RouteDescriptionViewController alloc] init]; [self presentModalViewController:routeDescriptionView animated:YES]; [routeDescriptionView release]; Works great, but the problem is: The map view in the background is not visible anymore (configuring alpha values of the modal view doesn't change anything). 2. Add RouteDescriptionView as a subview RouteDescriptionViewController *routeDescriptionView = [[RouteDescriptionViewController alloc] init]; [self.view addSubview:routeDescriptionView.view]; [routeDescriptionView release]; Works great as well, but the problem here is: I can't configure a close button on the subview to close/remove the subview (RouteDescriptionView). 3. Using UIAlertView Would work as expected, but the UIAlert is not really customizable and therefore not suitable for my needs. Any ideas how to achieve this?

  • How do I add two alternating UITableViews to an existing UINavigationController view?

    - by Ron Flax
    I'm new to iPhone development and I am writing an iPhone app that needs two different table views, which are selectable using a button bar or tab bar. These table views are both the same size, but only cover about two thirds of the screen from the bottom up. The top portion of the screen remains the same when either of these tables is displayed. I'd also like to animate (flip) these views when the user selects one or the other. The view that these two tables will be displayed on is the detail view of my app where the user has already selected an item from the primary screen's table. I'm using a UINavigationController to manage the primary and detail views and I have this working. I also have the first of these two detail tables working as part of my detail view, but I think it makes more sense to isolate the code for these two tables and not duplicate all of the code for the part of the detail view that doesn't change. I don't really care how these two table views are created (either in code or via IB). I've tried several things and I can't seem to figure it out. Any help or ideas (with sample code) would be greatly appreciated!

  • Keyboard blocking my view

    - by John Smith
    I have a UIView with another UIView inside it. On the inside UIView there is a textbox which I want to fill in. When I try to fill it in the keyboard blocks my view: The UIViewController has the following containerView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds]; self.view=containerView; //The apropriate releases etc are further on... When I touch it, the keyboard comes up as expected, but blocks the textbox I'm trying to fill in. How can I force the view to slide up? The front view OptionsFront * fv = [[OptionsFront alloc] initWithFrame:[UIScreen mainScreen].bounds]; [containerView addSubview:frontView]; In the front view is a subview CGRect bounds = CGRectMake(0.0f, 210.0f, 280.0f, 130.0f); sv = [[UIView alloc] initWithFrame:bounds]; [self addSubview:sv]; //added to frontView In sv is a textbox near the botton: rect = CGRectMake(70.0f, 20.0f, 100.0f, 27.0f); cf = [self createTextField_Rounded:rect holder:@"+ve"]; [sv addSubview:cf]; So cf happens to be near the bottom of the page. I expected that when I select it, the whole display would move up, but the keyboard just moves up and blocks it. What can I do? Appendix: - (UITextField *)createTextField_Rounded:(CGRect) frame holder:(NSString *) ph { UITextField *returnTextField = [[UITextField alloc] initWithFrame:frame]; returnTextField.borderStyle = UITextBorderStyleRoundedRect; returnTextField.textColor = [UIColor blackColor]; returnTextField.font = [UIFont systemFontOfSize:17.0]; returnTextField.delegate = self; returnTextField.keyboardType = UIKeyboardTypeNumbersAndPunctuation; returnTextField.returnKeyType = UIReturnKeyDone; returnTextField.clearButtonMode = UITextFieldViewModeWhileEditing; return returnTextField; }

  • Redirecting input to another view

    - by Jon
    My application is working fine on the normal iPad display, but I also need to output to VGA out. When I do this, I need to add the view to the external screen's window which seems to mean that I can't use it to accept input from the iPad screen. I want to redirect input from the iPad's window to the window displaying on the external screen. As far as I can tell there's no standard method of doing this. I've tried overriding hitTest on the iPad's window view to send it to the window on the external display, but the coordinates seem to get messed up in the process which makes it nigh unusable. I've also tried subclassing the iPad's UIWindow and catching events in sendEvent, then trying to send them to the external window, but this doesn't seem to work at all. Any help would be appreciated, I'm happy to post any code you would like to see. Thanks, Jon

  • UIImagePickerControllerDelegate Returns Blank "editingInfo" Dictionary Object

    - by Leachy Peachy
    Hi there, I have an iPhone app that calls upon the UIImagePickerController to offer folks a choice between selecting images via the camera or via their photo library on the phone. The problem is that sometimes, (Can't always get it to replicate.), the editingInfo dictionary object that is supposed to be returned by didFinishPickingImage delegate message, comes back blank or (null). Has anyone else seen this before? I am implementing the UIImagePickerControllerDelegate in my .h file and I am correctly implementing the two delegate methods: didFinishPickingImage and imagePickerControllerDidCancel. Any help would be greatly appreciated. Thank you in advance! Here is my code... my .h file: @interface AddPhotoController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate> { IBOutlet UIImageView *imageView; IBOutlet UIButton *snapNewPictureButton; IBOutlet UIButton *selectFromPhotoLibraryButton; } @property (nonatomic, retain) UIImageView *imageView; @property (nonatomic, retain) UIButton *snapNewPictureButton; @property (nonatomic, retain) UIButton * selectFromPhotoLibraryButton; my .m file: @implementation AddPhotoController @synthesize imageView, snapNewPictureButton, selectFromPhotoLibraryButton; - (IBAction)getCameraPicture:(id)sender { UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; picker.allowsImageEditing = YES; [self presentModalViewController:picker animated:YES]; [picker release]; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo { NSLog(@"Image Meta Info.: %@",editingInfo); UIImage *selectedImage = image; imageView.image = selectedImage; self._havePictureData = YES; [self.useThisPhotoButton setEnabled:YES]; [picker dismissModalViewControllerAnimated:YES]; } - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker { [picker dismissModalViewControllerAnimated:YES]; }

  • How to avoid piracy in iPhone apps by server side validation?

    - by prathumca
    As par my app requirement, there is a couple of scenarios that I need to handle. Scenario 1: To avoid piracy, I want to include some piece of code, whose job is sending both IMEI and Serial number of IPhone. Scenario 2: At server side, I've a database, which has a list of both IMEI and Serial No info. Here I wanna validate both IMEI and Serial numbers. If both are not matched then I can make sure that the app is pirated. Idea seems good. But I don't know how to handle these two scenarios in my app. Any help is greatly appreciated.

  • A little bit more complicated multiview App for Iphone

    - by Thomas Losert
    Hi, i'm new to iphone development. I spend several days by looking for how write muliview app for an Iphone OS. I found how to switch the diferent views without navigation hierarchy (in this article). It's great, but i want more complicated function. For example, i have three diferent views (view 1 - 3) and i can switch between them with technique from link 1. It works fine. My question is: How can i put UITabBarController on view 2, that shows own subviews (tabView 1 - 3) and how put UINavigationController on view 3, that shows own subviews (navView 1 - 2)? The reslut should look like that, one main view (view 1) with two buttons (for example), which switch me to "window" with UiTabBarController or UINavigationController. I found only tutorials, where UITabBarController was a first controller class, that shows directly from AppDelegate (something like default Xcode predefined scenarios). Thanks for your helpfull answer, or i will be crazy soon:).
