  • Display TableViews corresponding to segmentedControl in a single tableview without pushing a new view

    - by user1727927
    I have a tableViewController where I have used the Interface Builder to insert a Segmented Controller having two segments. Since by default, first segment is always selected, I am not facing any problem in displaying the tableview corresponding to first segment. However, when I click on the second segment, I want to display another tableView. Here goes the problem. I am calling newTableViewController class on clicking the second segment. Hence, this view is getting pushed instead. Please suggest me a method to have these two tableViews in the main tableView upon clicking the segments. I have used switch case for switching between the segments. Here's the relevant part of the code: This method is in the FirstTableViewController since first segment is by default selected. -(IBAction) segmentedControlChanged { switch(segmentedControl.selectedSegmnentIndex) { case 0: //default first index selected. [tableView setHidden:NO]; break; case 1: NewViewController *controller=[[NewViewController alloc] initWithNibName:@"NewViewController" bundle:nil]; self.navigationController pushViewController:controller animated:YES]; [controller release]; break; default: break; } }

  • Check if NSString exists in custom object in NSArray

    - by Paul Peelen
    I have an NSArray with Store objects. Each Store object has two NSString objects; StoreID and Name. I would like to check quickly if an ID exists in this NSArray with Store objects. Example: Store *s1 = [[Store alloc] init]; s1.name = @"Some Name"; s1.id = @"123ABC"; Store *s2 = [[Store alloc] init]; s2.name = @"Some Other Name"; s2.id = @"ABC123"; NSArray *array = [[NSArray alloc] initWithObjects:s1, s2, nil]; NSString *myIdOne = @"ABCDEF"; NSString *myIdTwo = @"123ABC"; BOOL myIdOneExists = ...? BOOL myIdTwoExists = ...? Its the ...? I need to figure out. I know I can do this using a for loop and break when found... but this seems to me like an nasty approach since the NSArray could contain thousands of objects,... theoretically. So I would like to know about a better solution.

  • Overlay an image over video using OpenGL ES shaders

    - by BlueVoodoo
    I am trying to understand the basic concepts of OpenGL. A week into it, I am still far from there. Once I am in glsl, I know what to do but I find getting there is the tricky bit. I am currently able to pass in video pixels which I manipulate and present. I have then been trying to add still image as an overlay. This is where I get lost. My end goal is to end up in the same fragment shader with pixel data from both my video and my still image. I imagine this means I need two textures and pass on two pixel buffers. I am currently passing the video pixels like this: glGenTextures(1, &textures[0]); //target, texture glBindTexture(GL_TEXTURE_2D, textures[0]); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_BGRA, GL_UNSIGNED_BYTE, buffer); Would I then repeat this process on textures[1] with the second buffer from the image? If so, do I then bind both GL_TEXTURE0 and GL_TEXTURE1? ...and would my shader look something like this? uniform sampler2D videoData; uniform sampler2D imageData; once I am in the shader? It seems no matter what combination I try, image and video always ends up being just video data in both these. Sorry for the many questions merged in here, just want to clear my many assumptions and move on. To clarify the question a bit, what do I need to do to add pixels from a still image in the process described? ("easy to understand" sample code or any types of hints would be appreciated).

  • App Crashing Inspite of Being ARC Enabled

    - by proctr
    I have been working on an iOS App for sometime now and its almost ready to submit. However, when I gave it to few people for testing purposes (running iOS 5)..they reported cases where the app crashes and the home screen is displayed on the phone OR a frozen app screen appears with no response whatsoever The app is ARC enabled and Xcode shows no warnings. So, I'm relli tensed about what's going wrong. I have declared properties in the following fashion: @property (nonatomic) IBOutlet UILabel *devCountLabel; @property (nonatomic) IBOutlet UIView *splashView; Likewise other properties are declared. Could anyone provide a solution ASAP. It is mainly a network based app and thus, CoreData usage is minimum.. Anyway, I'm running out of time..So Please provide a fix asap..oh and thanks a ton for it. PS: The App doesn't crash in the simulator, so I'm guessing it has something related to memory. And the crashes are random. So, repeating a set of steps to reproduce the crash doesn't help either. For Eg. When I click a button, modalViewControllerAnimation results in normal case. Now this occurs as expected most of the time and freezes the app other times.

  • Prevent custom AccessoryView from showing selection when it's UITableViewCell is selected.

    - by groomsy
    To reproduce this, create a UITableView that contains cells with custom AccessoryViews (such as buttons to perform a specific action where touching the other part of the UITableViewCell should perform a different action). If you touch (select) the UITableView, the AccessoryView shows selection (as thought it was touched) as well. I want to prevent this and only show the AccessoryView's selected state when they actually touch the AccessoryView. Thanks in advance, groomsy

  • Problem with CFNetRegister

    - by xtrahotsauce
    I'm trying to work with CFNetServices by trying to start up and publish a service asynchronously. I'm trying to use the example code from here: http://developer.apple.com/mac/library/documentation/Networking/Conceptual/NSNetServiceProgGuide/Articles/CFNetServices.html#//apple_ref/doc/uid/30001276-SW3, but CFNetRegisterWithOptions always fails. (CFNetRegister is deprecated now). When I print out the error struct, it looks like this: (gdb) p error $1 = { domain = 10, error = -72004 } Which doesn't seem correct to me. Does anyone know what might be wrong? Thanks!

  • UINavigationController's back button disappears?

    - by QAD
    I notice something strange happens to one of my view controller: the back button disappears, yet it's possible to go back to previous view controller by tapping the top left corner (i.e where the button should reside). In my entire file there's no line that set self.navigationItem.hidesBackButton to YES; also NSLog prints 0 as self.navigationItem.hidesBackButton's value in viewDidLoad. This occurs in both the simulator and real device. Any ideas?

  • How to make an private property?

    - by mystify
    I tried to make a private property in my *.m file: @interface MyClass (Private) @property (nonatomic, retain) NSMutableArray *stuff; @end @implementation MyClass @synthesize stuff; // not ok Compiler claims that there's no stuff property declared. But there's a stuff. Just in an anonymous category. Let me guess: Impossible. Other solutions?

  • Bind Java program to Cocoa interface

    - by Kevin
    Hi, would it be possible to bind a Java application to a Cocoa graphical interface? I'm working in Eclipse right now, on my mac, and am wondering if Interface Builder could be used to construct a new interface so that I don't have to look at Swing all day. Any ideas/suggestions? Thanks!

  • How to speed up saving a UIImagePickerController image from the camera to the filesystem via UIImagePNGRepresentation()?

    - by kazuhito0000
    I'm making an applications that let users take a photo and show them both in thumbnail and photo viewer. I have NSManagedObject class called photo and photo has a method that takes UIImage and converts it to PNG using UIImagePNGRepresentation() and saves it to filesystem. After this operation, resize the image to thumbnail size and save it. The problem here is UIImagePNGRepresentation() and conversion of image size seems to be really slow and I don't know if this is a right way to do it. Tell me if anyone know the best way to accomplish what I want to do. Thank you in advance.

  • presentmodalviewcontroller not working properly in Application Delegate in iPhone

    - by sujyanarayan
    Hi, I'm using two UIViewController in Application Delegate and navigating to UIViewController using presentmodalviewcontroller. But Problem is that presentmodalviewcontroller works for first time UIViewController and when i want to navigate to second UIViewController using presentmodalviewcontroller then its showing first UIViewController. The following is the code:- -(void)removeTabBar:(NSString *)str { HelpViewController *hvc =[[HelpViewController alloc] initWithNibName:@"HelpViewController" bundle:[NSBundle mainBundle]]; VideoPlaylistViewController *vpvc =[[VideoPlaylistViewController alloc] initWithNibName:@"VideoPlaylistViewController" bundle:[NSBundle mainBundle]]; if ([str isEqualToString:@"Help"]) { [tabBarController.view removeFromSuperview]; [vpvc dismissModalViewControllerAnimated:YES]; [viewController presentModalViewController:hvc animated:YES]; [hvc release]; } if ([str isEqualToString:@"VideoPlaylist"]) { [hvc dismissModalViewControllerAnimated:YES]; [viewController presentModalViewController:vpvc animated:YES]; [vpvc release]; } } Can Somebody help me in solving the problem?

  • Using iPhone Core Data to many Relationship

    - by BLeB
    When I define a to many relationship between entities in Xcode and then generate the data class from the entity I get a header with the following methods defined: @interface PriceList (CoreDataGeneratedAccessors) - (void)addItemsObject:(PriceListItem *)value; - (void)removeItemsObject:(PriceListItem *)value; - (void)addItems:(NSSet *)value; - (void)removeItems:(NSSet *)value; @end When I attempt to call addItemsObject with the following code a doesNotRecognizeSelector exception is thrown. PriceListItem *item = [NSEntityDescription insertNewObjectForEntityForName:@"PriceListItem" inManagedObjectContext:managedObjectContext]; item.cat = [attributeDict valueForKey:@"c"]; item.sel = [attributeDict valueForKey:@"s"]; [self addItemsObject:item]; From what I have read I do not have to implement these methods and that they are generated at runtime. Any ideas?

  • Optimal way to initialize varying objects

    - by John Smith
    I have to initialize a lot of different types of objects based on an integer parameter. They all have the same overall initialization methods. At the moment I have the following code #def APPLE 1 #def PEAR 2 switch (t) { case APPLE: newobj = [[FApple alloc] init]; break; case PEAR: newobj = [[FPear] alloc] init]; break; default: retobj = nil; } I believe there must be a better way to do this. When I add FOrange I have to go and add another line here. What would be a better way?
