  • Iphone - UIView not displayed

    - by Raphael Pinto
    Hi, I have a strange problem with a UIView : I want to show an Activity Indicator View that I created with Interface Builder to indicate long running activity. In the viewDidLoad function of my principal viewController I init the ActivityIndicator View like this : - (void)viewDidLoad { [super viewDidLoad]; appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; load = [[ActivityIndicatorViewController alloc] init]; ... When I push a button it call this IBAction : - (IBAction)LaunchButtonPressed{ // Show the Activity indicator view. [self.view addSubview:load.view]; // eavy work [self StartWorking]; // Hide the loading view. [load.view removeFromSuperview]; } In the StartWorking function, I ask a request to an internet serveur and parse the XML file that it return me. The problem is that if I Call my StartWorking function, the application do not start by showing the Activity Indicator view but with the StartWorking function. Whereas if I remove the call to StartWorking function, the view is shown. Is someone able to explain me why? :s

  • iPhone: Creating a hierarchy-based table navigation.

    - by Jack Griffiths
    Hi there, I've tried to ask this before, but nothing got answered. Basically, I would like someone to explain to me how to create a table, which when a cell is tapped, pushes the user to the next view for that cell. I have this so far: Click here to view what I have. I would further like to, say when CSS is tapped, it goes to a new view which has another table in it. This table would then take the user to a detail view, which is scrollable and you can switch pages through it. I would appreciate longer, more structured tutorials on how to do each and every bit to get it to work. Here's my array in my implementation file: - (void)viewDidLoad { arryClientSide = [[NSArray alloc] initWithObjects:@"CSS", @"HTML", @"JavaScript", @"XML", nil]; arryServerSide = [[NSArray alloc] initWithObjects:@"Apache", @"PHP", @"SQL", nil]; self.title = @"Select a Language"; [super viewDidLoad]; } and my .h: @interface RootViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource> { IBOutlet UITableView *tblSimpleTable; NSArray *arryClientSide; NSArray *arryServerSide; } My current code crashes the script, and this error is returned in the console: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "NextView" nib but didn't get a UITableView.' If that error is the source of why it's not pushing, then an explanation of how to remedy that would also be appreciated Many thanks, Jack

  • Whats the best way to stop this app crash when buttons rapidly pressed iphone obj-c

    - by dubbeat
    Hi, I'm not entirely sure why this crash is happening and I'd like to get advice on the best way to deal with it. My app has 3 buttons. Each button requests a different XML file from a server which is used to populate a table view. If I rapidly press the buttons in sequence , button 1 button 2 button3 button 1 button 2 button3 button 1 button 2 button3 the application quits. What could be causing this. Would id be in the NSURLRequest side of things or the table view population side? How would you suggest I stop this behaviour? I was going to just set a boolean "isRequesting" to true when a button is pressed and set it to false when the table view is finished populating. If any button is pressed while isRequesting is True they do nothing. Does that sound wise or is there a better way? Thanks, dub

  • iPhone Core Data does not refresh table

    - by Brian515
    Hi all, I'm trying to write an application with Core Data, and I have been able to successfully read and write to the core data database. However, if I write to the database in one view controller, my other view controllers will not see the change until the app is closed then reopened again. This is really frustrating. I'm not entirely sure how to get the refresh - (void)refreshObject:(NSManagedObject *)object mergeChanges:(BOOL)flag method to work. How do I get a reference to my managed object? Anyways, here's the code I'm using to read the data back. This is in the viewDidLoad method. NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Website" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"siteName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if(mutableFetchResults == nil) { //Handle the error } [self setNewsTitlesArray:mutableFetchResults]; [mutableFetchResults release]; [request release]; [newsSourcesTableView reloadData]; Thanks for help in advance!

  • iPhone: scale UIView about a specific point

    - by Greg Maletic
    I want to animate the scaling down of a UIView, but not about its center: about a different point. As a shot in the dark, I tried translating the view, scaling, then translating back, using a series of CGAffineTransforms. But it doesn't work: it still scales about the center. Anyone know how to do this? Thanks very much.

  • UITextView like iPhone Notes application

    - by Mark
    I am trying to recreate the Notes application. So far I got the following: textView = [[UITextView alloc] initWithFrame:CGRectMake(25.0, 30.0, 295.0, 214.0)]; textView.delegate = self; textView.backgroundColor = [UIColor clearColor]; textView.font = [UIFont fontWithName:@"MarkerFelt-Thin" size:19.0]; [self.view addSubview:textView]; The thing I dont know is how they were able to put the date on top like a header (it is within the UIScrollView that is obvious). Also under every text there is a line where did that came from. Does someone have an idea or a sample project I can take a look at?

  • Iphone: Problem with moving back and forth between two UIViewController

    - by Harry Pham
    Let me first describe the context of the problem. I have 2 UIViewController call AdminViewController and ButtonReorderViewController. AdminViewController contain 1 button. ButtonReorderViewController contains 1 button and 1 picture. Button in AdminViewController tie to an event call goToReorderButton. The content of goToReorderButton are below: ButtonReorderViewController *buttonReorder = [[ButtonReorderViewController alloc] initWithNibName:@"ButtonReorderViewController" bundle:[NSBundle mainBundle]]; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:buttonReorder]; //Add a Navigation Controller to the root view [navController setNavigationBarHidden:TRUE]; buttonReorder = (ButtonReorderViewController *) navController; [[buttonReorder view] setFrame:CGRectMake(0, -20, 320, 470)]; [self.view addSubview:buttonReorder.view]; I use UINavigationController to allow me to swipe left and right.So I am in AdminViewController, and I click on goToReorderButton, it load ButtonReorderViewController. I am able to swipe left and right (awesome !!!) So I click the button in ButtonReorderViewController call goToAdmin, simply to go back to the AdminViewController -(void) goToAdmin{ [self.view removeFromSuperview]; } However, as soon as I go back to AdminViewController, I cant click anything at all. The program does not seg fault, it just that I cant click the button at all. if I remove the line buttonReorder = (ButtonReorderViewController *) navController; inside goToReorderButton, then everything work fine. Any idea how to fix this?

  • iPhone application lifecycle

    - by iter
    InterfaceBuilder generates this method for me in fooAppDelegate.m: - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } IB also puts UIWindow *window; in fooAppDelegate.h and @synthesize window; in fooAppDelegate.m, and correspondingly for navigationController. IB generates code to release window and navigationController in dealloc. I cannot see any code that allocates and initializes the window and the navigationController. I wonder where that happens.

  • Exposing headers on iPhone static library

    - by leolobato
    Hello guys, I've followed this tutorial for setting up a static library with common classes from 3 projects we are working on. It's pretty simple, create a new static library project on xcode, add the code there, a change some headers role from project to public. The tutorial says I should add my library folder to the header search paths recursively. Is this the right way to go? I mean, on my library project, I have files separated in folders like Global/, InfoScreen/, Additions/. I was trying to setup one LOKit.h file on the root folder, and inside that file #import everything I need to expose. So on my host project I don't need to add the folder recursively to the header search path, and would just #import "LOKit.h". But I couldn't get this to work, the host project won't build complaining about all the classes I didn't add to LOKit.h, even though the library project builds. So, my question is, what is the right way of exposing header files when I setup a Cocoa Touch Static Library project on xCode?

  • iPhone GUI for real-time log message display

    - by zer0stimulus
    My goal is to have a screen on my GUI dedicated to logging real-time messages generated by my internal components. A certain limit will be set on the log messages so that older messages are pruned. I'm thinking about implementing using a UITextView with a NSMutableString to store the output. I would have to perform manual pruning somehow on the NSMutableString object. Is a better way to implement this?

  • iPhone: UIImageView not showing images

    - by George
    Hello, I've got UIImageView drawn in my nib-file and it's connected to a imageView iboutlet. I can load single pictures which will show up very nicely, but when it comes to drawing many images separately as like an animation, images won't show. I've got drawImage() function which takes NSData-objects(image data) and draws it to a screen(imageView). Main function has got for loop which loops 300 times as quickly as it can and each time it calls that drawImage function and passes different image data to it. Sometimes when I execute this code, last picture from that "animation" shows up, sometimes not at all. Maybe I need to schedule enough time for imageView so that the image can be shown? Hope someone has some clues. Thanks in advance!

  • iPhone OS syntax highlighting UITextField

    - by Jack
    Hi, I am working on an application and would like to apply some syntax highlighting to some user entered text. I have looked around and some people are suggesting that this can be done in OS 3.2+ but posts seem to be from before the NDA was lifted. Does anyone have any suggestions as to how to go about doing this? I would be interested in releasing the code on github if I could get it implemented well, as I have never done so before. Thanks

  • iPhone SDK - CGBitmapContextCreate

    - by nax_
    Hi, I would like to create an image of my own. I already know its width (320*2 = 640) and height (427). So I have some raw data : unsigned char *rawImg = malloc(height * width * 4 *2 ); Then, I will fill it :) Then, I have to do something like that to get a bitmap and return a (UIImage *) : ctx = CGBitmapContextCreate(rawImg,width*2,height,8, ???, ???, kCGImageAlphaPremultipliedLast); UIImage * imgFinal = [UIImage imageWithCGImage:CGBitmapContextCreateImage(ctx)]; CGContextRelease(ctx); return imgFinal; But I don't know how to create my context ctx, as you can see with the "???", even tough I read the documentation... Please help ! Thanks :)
