  • Image Transformation on iPhone, how to?

    - by Horace Ho
    Since I cannot pre-render all the images in PNGs and real-time image transformation functions are required, namely: skew perspective (like the transform action found in Photoshop) Which API (CoreAnimation? OpenGL ES?) should I look into? Even better, is there any sample code around? Thanks!

  • Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

    - by user170030
    Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

  • How do I push another viewController onto the navigationController from within a tabviewController?

    - by user207788
    Hi, I have a project set up using these two tutorials. http://twilloapp.blogspot.com/2009/03/how-to-embed-navigation-controller.html and the link for the second tutorial is at the bottom of the first. The tutorial is slightly outdated but I managed to get it to work as advertised. Now I want to push a new detailedView onto the NavigationController when a user touches a row in the table view. So I added this to my MyTableViewController.m file. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. SecondViewController *detailViewController = [[SecondViewController alloc] initWithNibName:@"SecondViewController.xib" bundle:nil]; // ... // Pass the selected object to the new view controller. [self.navigationController pushViewController:detailViewController animated:YES]; [detailViewController release]; } Now when I run this project and touch a row in my table view I am getting an error: asm_Terminating_due_to_uncaught_exception IT seems to be having an issue loading the SecondViewController from nib, however I checked the detailViewController and it is not nil. I know I am missing something and it is more than likely something simple. Please help. Thanks, Bruce

  • Get String Instead of Source - Xcode Cocoa

    - by Kevin
    Hello everyone, I have a program that will scan the contents of a website, and display it in a textbox. The problem is that it shows the html source. For example if my html code was: <html> <body> <p>Hello</p> </body> </html> instead of just showing hello, it'll show the code above... How can I get my objective c program to just read the hello, and not the html source.. I was assuming that it was the encoding when reading the website, but I might be possibly wrong.. I would greatly appreciate it if someone could give me a reasonable answer.. Best Regards, Kevin

  • How to prevent modal view controllers flashing when changing

    - by KP Overflow
    I have three view controllers, let's call them A, B and C. When a button is pressed on view A, view B is shown using presentModalViewController:animated: When the finish button is pressed on screen B, it dismisses itself. View A is notified whereupon it immediately shows view C, again using presentModalViewController:animated: The problem is that view A's content is momentarily flashed on the screen between view B closing and view C opening. I can get around this by making view A blank and moving it's current content to a new view, D. (For various reasons, I don't want view B to own view C, that's why it's not opening it) Am I over-complicating this? I'm sure there is a smarter way to go? ThanksT

  • performSelector:withObject:afterDelay: not working from scrollViewDidZoom

    - by oldbeamer
    Hi all, I feel like I should know this but I've been stumped for hours now and I've run out of ideas. The theory is simple, the user manipulates the zoom and positioning in a scrollview using a pinch. If they hold that pinch for a short period of time then the scrollview records the zoom level and content offsets. So I thought I'd start a performSelector:withObject:withDelay on the scrollViewDidZoom delegate method. If it expires then I record the settings. I delete the scheduled call every time scrollViewDidZoom is called and when the pinch gesture finishes. This is what I have: - (void)scrollViewDidZoom:(UIScrollView *)scrollView{ NSLog(@"resetting timer"); [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(positionLock) object:nil]; [self performSelector:@selector(positionLock) withObject:nil afterDelay:0.4]; } -(void)positionLock{ NSLog(@"position locked "); } - (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale{ NSLog(@"deleting timer"); [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(positionLock) object:nil]; } This is the output: 2010-05-19 22:43:01.931 resetting timer 2010-05-19 22:43:01.964 resetting timer 2010-05-19 22:43:02.231 resetting timer 2010-05-19 22:43:02.253 resetting timer 2010-05-19 22:43:02.269 resetting timer 2010-05-19 22:43:02.298 resetting timer 2010-05-19 22:43:05.399 deleting timer As you can see the delay between the last and second last events should have been more than enough for the delayed selector call to execute. If I replace performSelector:withObject:withDelay with plain old performSelector: I get this: 2010-05-19 23:08:30.333 resetting timer 2010-05-19 23:08:30.333 position locked 2010-05-19 23:08:30.366 resetting timer 2010-05-19 23:08:30.367 position locked 2010-05-19 23:08:30.688 deleting timer Which isn't what I want but serves to show that it's only the delay that's causing it to not function, not something to do with the selector not being declared in the header, being misspelt or any other reason. Any ideas as to why it's not working?

  • sqlite3 crashes for second insert statement

    - by Ayaz Alavi
    My App is crashing on statement (sqlite3_step(insertAlert) == SQLITE_DONE) when executed for i = 1. Can anybody tell me why it is crashing? sqlite3_stmt *insertAlert; textmeAppDelegate *textme = (textmeAppDelegate *)[[UIApplication sharedApplication] delegate]; NSString *insert = @"INSERT INTO alerts (alert_id, email_address, messege_text, when_to_send, how_often_send, recipient_phone_number) VALUES(?, ?, ?, ?, ?, ?)"; if(sqlite3_prepare_v2(textme.dbConn, [insert UTF8String], -1, &insertAlert, NULL) == SQLITE_OK) { NSDictionary *tmpDictionary; NSString *alertId; for(int i=0; i<[keys count]; i++) { alertId = [NSString stringWithFormat:@"%@", [keys objectAtIndex:i]]; tmpDictionary = [NSDictionary dictionaryWithDictionary:[dictionary2 objectForKey:alertId]]; sqlite3_bind_text(insertAlert, 1, [NSString stringWithFormat:@"%@", [tmpDictionary objectForKey:@"alert_id"]], -1, SQLITE_TRANSIENT); sqlite3_bind_text(insertAlert, 2, [NSString stringWithFormat:@"%@", [tmpDictionary objectForKey:@"email_address"]], -1, SQLITE_TRANSIENT); sqlite3_bind_text(insertAlert, 3, [NSString stringWithFormat:@"%@", [tmpDictionary objectForKey:@"messege_text"]], -1, SQLITE_TRANSIENT); sqlite3_bind_text(insertAlert, 4, [NSString stringWithFormat:@"%@", [tmpDictionary objectForKey:@"when_to_send"]], -1, SQLITE_TRANSIENT); sqlite3_bind_text(insertAlert, 5, [NSString stringWithFormat:@"%@", [tmpDictionary objectForKey:@"how_often_send"]], -1, SQLITE_TRANSIENT); sqlite3_bind_text(insertAlert, 6, [NSString stringWithFormat:@"%@", [tmpDictionary objectForKey:@"recipient_phone_number"]], -1, SQLITE_TRANSIENT); if (sqlite3_step(insertAlert) == SQLITE_DONE) { sqlite3_finalize(insertAlert); sqlite3_clear_bindings(insertAlert); } else { NSAssert1(0, @"Error while creating add statement.

  • Android insert into sqlite database

    - by Josh
    I know there is probably a simple thing I'm missing, but I've been beating my head against the wall for the past hour or two. I have a database for the Android application I'm currently working on (Android v1.6) and I just want to insert a single record into a database table. My code looks like the following: //Save information to my table sql = "INSERT INTO table1 (field1, field2, field3) " + "VALUES (" + field_one + ", " + field_two + ")"; Log.v("Test Saving", sql); myDataBase.rawQuery(sql, null); the myDataBase variable is a SQLiteDatabase object that can select data fine from another table in the schema. The saving appears to work fine (no errors in LogCat) but when I copy the database from the device and open it in sqlite browser the new record isn't there. I also tried manually running the query in sqlite browser and that works fine. The table schema for table1 is _id, field1, field2, field3. Any help would be greatly appreciated. Thanks!

  • How do I reference my MainViewController from another class?

    - by todd412
    Hi, I am building an iPhone Utility app that uses UIImageView to display an animation. Within the MainViewController's viewDidLoad() method, I am creating an instance of a CustomClass, and then setting up the animations: - (void)viewDidLoad { [super viewDidLoad]; cc = [CustomClass new]; NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"image-1-off.jpg"], [UIImage imageNamed:@"image-2-off.jpg"], [UIImage imageNamed:@"image-3-off.jpg"], [UIImage imageNamed:@"image-4-off.jpg"], nil]; offSequence = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; offSequence.animationImages = imageArray; offSequence.animationDuration = .8; offSequence.contentMode = UIViewContentModeBottomLeft; [self.view addSubview:offSequence]; [offSequence startAnimating]; } That works fine. However, I would like to be able to move all the above code that sets up the UIImageView into my CustomClass. The problem is in the second to last line: [self.view addSubview:offSequence]; I basically need to replace 'self' with a reference to the MainControllerView, so I can call addSubview from within my CustomClass. I tried creating an instance var of CustomClass called mvc and a setter method that takes a reference to the MainViewController as an argument as such: - (void) setMainViewController: (MainViewController *) the_mvc { mvc = the_mvc; } And then I called it within MainViewController like so: [cc setMainController:MainViewController:self]; But this yields all sorts of errors which I can post here, but it strikes me that I may be overcomplicating this. Is there an easier way to reference the MainViewController that instanatiated my CustomClass?

  • Showing value of UISlider inside App Prefs?

    - by Garrett H
    I have a settings bundle, working perfectly, that I would like to customize a bit. I have, among other things, a PSSliderSpecifier and a PSTitleValueSpecifier. What I would like to do is change the value of the PSTitleValueSpecifier to show the current value of the slider, preferably updating every time the slider's value changes (Actually, what I'd like even more would be displaying the slider's value on the same row as the slider). I know the settings bundle is rather strict about what you're allowed to do in it, but is there any way of doing this?

  • xcode collect2: ld returned 1 exit status - how to resolve?

    - by Remover
    From what I have read this is supposed to be when the linker (not exactly sure how that works) can't find a symbol. the symbol in question is: SCNetworkReachabilityCreateWithAddress as can be seen from the full error message below. the thing is that the correct framework is added to my target. xcode recognises the symbol OK, i.e. there is no error message in the .m file. the .m file is added to the correct target so I'm not at all sure what to do. Any ideas please? "SCNetworkReachabilityCreateWithAddress", referenced from: -[AppWelcomeVC viewDidLoad] in AppWelcomeVC.o ld: symbol(s) not found collect2: ld returned 1 exit status
