  • Can a tab bar controller added to a uitableview?

    - by Sheehan Alam
    I have a View that contains a UITableView and a UITabBarController. I have set my IBOutlets, but the UITabbarController does not appear. Do I need to do anything else to allow it to appear? Note: I don't want the tab-bar to be displayed throughout the entire application. Only on one specific view.

  • Second query to SQLite (on iPhone) errors.

    - by Luke
    Hi all, On the iPhone, I am developing a class for a cart that connects directly to a database. To view the cart, all items can be pulled from the database, however, it seems that removing them doesn't work. It is surprising to me because the error occurs during connection to the database, except not the second time I connect even after the DB has been closed. #import "CartDB.h" #import "CartItem.h" @implementation CartDB @synthesize database, databasePath; - (NSMutableArray *) getAllItems { NSMutableArray *items = [[NSMutableArray alloc] init]; if([self openDatabase]) { const char *sqlStatement = "SELECT * FROM items;"; sqlite3_stmt *compiledStatement; if(sqlite3_prepare_v2(cartDatabase, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { while(sqlite3_step(compiledStatement) == SQLITE_ROW) { int rowId = sqlite3_column_int(compiledStatement, 0); int productId = sqlite3_column_int(compiledStatement, 1); NSString *features = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; int quantity = sqlite3_column_int(compiledStatement, 3); CartItem *cartItem = [[CartItem alloc] initWithRowId:rowId productId:productId features:features quantity:quantity]; [items addObject:cartItem]; [cartItem release]; } } sqlite3_finalize(compiledStatement); } [self closeDatabase]; return items; } - (BOOL) removeCartItem:(CartItem *)item { sqlite3_stmt *deleteStatement; [self openDatabase]; const char *sql = "DELETE FROM items WHERE id = ?"; if(sqlite3_prepare_v2(cartDatabase, sql, -1, &deleteStatement, NULL) != SQLITE_OK) { return NO; } sqlite3_bind_int(deleteStatement, 1, item.rowId); if(SQLITE_DONE != sqlite3_step(deleteStatement)) { sqlite3_reset(deleteStatement); [self closeDatabase]; return NO; } else { sqlite3_reset(deleteStatement); [self closeDatabase]; return YES; } } - (BOOL) openDatabase { if(sqlite3_open([databasePath UTF8String], &cartDatabase) == SQLITE_OK) { return YES; } else { return NO; } } - (void) closeDatabase { sqlite3_close(cartDatabase); } The error occurs on the line where the connection is opened in openDatabase. Any ideas? Need to flush something? Something gets autoreleased? I really can't figure it out. --Edit-- The error that I receive is GDB: Program received signal "EXC_BAD_ACCESS". --Edit-- I ended up just connecting in the init and closing in the free methods, which might not be the proper way, but that's another question altogether so it's effectively persistent instead of connecting multiple times. Still would be nice to know what was up with this for future reference.

  • How to check in which position (landscape or portrait) os the iPhone now?

    - by Knodel
    I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation. If I write just - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) if (interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { //Code } else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) { //Code } } The view just goes crazy if user rotated the device before shaking. Is there a method to get iPhones current orientation?

  • UIView rotate and than move

    - by user1790354
    I have problem with rotating and moving image (UIView). If I use this for rotate: [UIView beginAnimations: @"rotate" contex: nil]; [UIView setAnimationDuration: 1]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; spaceShip.transform = CGAffineTransformMakeRotation (angle); // spaceShip is the UIView [UIView commitAnimations]; And this to move: [UIView beginAnimations: @"move" contex: nil]; [UIView setAnimationDuration: 1]; [UIView setAnimationBeginsFromCurrentState: YES]; [UIView setAnimationCurve: UIViewAnimationCurveLinear]; spaceShip.center = destanation // destanation is a point where user tap [UIView commitAnimations]; It's working well one at a time. But together this two animations don't work. Space Ship is rotating, but does not move in direction. Where my mistake? P.S. Early I have specify anchor point (0.5, 0.5). But when I rotate image it coordinates is changing.

  • Month TableView Organizer

    - by rson
    I need to create a table view with 1 or 2 sections, depending on certain conditions. The first section needs to contain all of the remaining months of the current year, and the second section contains the preceding months of the next year, up to but not including the current month. Example: 2009 November December 2010 January February March April May June July August September October This would be the scenario with the current month of November. However, if it were January, there would be only 1 section containing all 12 months of the current year. This all needs to be dependent on the date settings of the phone.

  • iPhone SDK File Handler with iOS 4 Background Processes

    - by David Higgins
    The "application:applicationDidFinishLaunchingWithOptions:" message does not get called when an application is sitting in the background in iOS 4, and I'm trying to figure out how to be notified when the application is brought back into the foreground by another application. My application registers itself as a handler for certain file types, and Safari and other supported applications allow passing the files over to my app. This works great if the app is closed before I try to use it, but fails otherwise. In my application:applicationDidFinishLaunchingWithOptions: I have: NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey]; if([url isFileURL]) { } [self.window makeKeyAndVisible]; return YES; As stated already, this works great so far for starting the app when it's not sitting in the background - but when I switch back over to Safari or Mail and try to open a new file that is supported, my application wakes up from the background and becomes active again but I can't see any "withOptions" overrides for application:applicationWillEnterForeground: or any way to identify what was passed in when it enters the foreground. What would be the appropriate way to receive these "open file notifications" when the application is in the background?

  • UIImageView not displaying image when property is set too early

    - by Undeadlegion
    I have an image I want to display inside a UIView. In Interface Builder, the UIView is the root and a UIImageView is its child. The view is connected to view controller's view outlet, and the image view is connected to the image view outlet: @property (nonatomic, retain) IBOutlet UIImageView *imageView; If I try to set the image property of UIImageView before it's visible, the image doesn't show up. TestView *testView = [[TestView alloc] initWithNibName:@"TestView" bundle:nil]; testview.imageView.image = [logos objectAtIndex:indexPath.row]; [self.navigationController pushViewController:testView animated:YES]; If, however, I pass the image to the controller and set the image property in view did load, the image becomes visible. TestView *testView = [[TestView alloc] initWithNibName:@"TestView" bundle:nil]; testview.image = [logos objectAtIndex:indexPath.row]; [self.navigationController pushViewController:testView animated:YES]; - (void)viewDidLoad { [super viewDidLoad]; imageView.image = image; } What is causing the image to not show up in the first scenario?

  • Detect iphone region

    - by camilo
    Hi. In my app, the user is supposed to insert a phone number, which is then displayed somewhere else. In the contacts application, when displaying a phone number, it automatically appears in the format of the language selected by the user. Is there a way to do this automatically, or a way to detect the region and then adapt the displayed string?

  • Paged UIScrollView with UIImageViews only showing first UIImageVIew

    - by Jonathan Brown
    I am working on a paged UIScrollView, but it only wants to show the first UIImageView within it. I add each UIImageView at an offset of the width of the scroll view, so that should create each page. When run, it says the scroll view is the right number of pages, but the images don't show. Any help would be much appreciated! int numSlides = NUM_TUTORIAL_SLIDES; NSString *fileName; UIImageView *slideImageView; CGRect slideFrame; for (int i = 1; i <= numSlides; i++) { slideFrame.origin.x = self.tutorialScrollView.frame.size.width * (i-1); slideFrame.origin.y = 0; slideFrame.size = self.tutorialScrollView.frame.size; slideImageView = [[UIImageView alloc] initWithFrame:slideFrame]; if([[AppManager sharedManager] is4inchScreen]) { fileName = [NSString stringWithFormat:@"Slide%[email protected]", i]; } else { fileName = [NSString stringWithFormat:@"Slide%[email protected]", i]; } slideImageView.image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:fileName ofType:nil]]; [self.tutorialScrollView addSubview:slideImageView]; [slideImageView release]; } self.tutorialScrollView.contentSize = CGSizeMake(self.tutorialScrollView.frame.size.width * numSlides, self.tutorialScrollView.frame.size.height); self.tutorialScrollView.delegate = self;

  • How do I package an SDK (static lib + xibs) for the iPhone?

    - by twhipple
    I am creating an SDK for a client that includes predefined view controllers. What is the recommended way to package everything (static lib, .xib(s), and .png(s)) for easy use? SDKs that I've used (e.g. Pinch Media) do a good job of just providing a .h and .a file that expose only user accessible functionality and hiding everything else. As I read Apple's documentation, a framework would be ideal but is not permitted on iPhoneOS. Some key requirements: Don't expose source or object internals. Be easy to use & set up. Work on both the device and simulator. Thanks!

  • Reference properteries declared in a protocol and implemented in the anonymous category?

    - by Heath Borders
    I have the following protocol: @protocol MyProtocol @property (nonatomic, retain) NSObject *myProtocolProperty; -(void) myProtocolMethod; @end and I have the following class: @interface MyClass : NSObject { } @end I have a class extension declared, I have to redeclare my protocol properties here or else I can't implement them with the rest of my class. @interface()<MyProtocol> @property (nonatomic, retain) NSObject *myExtensionProperty; /* * This redeclaration is required or my @synthesize myProtocolProperty fails */ @property (nonatomic, retain) NSObject *myProtocolProperty; - (void) myExtensionMethod; @end @implementation MyClass @synthesize myProtocolProperty = _myProtocolProperty; @synthesize myExtensionProperty = _myExtensionProperty; - (void) myProtocolMethod { } - (void) myExtensionMethod { } @end In a consumer method, I can call my protocol methods and properties just fine. Calling my extension methods and properties produces a warning and an error respectively. - (void) consumeMyClassWithMyProtocol: (MyClass<MyProtocol> *) myClassWithMyProtocol { myClassWithMyProtocol.myProtocolProperty; // works, yay! [myClassWithMyProtocol myProtocolMethod]; // works, yay! myClassWithMyProtocol.myExtensionProperty; // compiler error, yay! [myClassWithMyProtocol myExtensionMethod]; // compiler warning, yay! } Is there any way I can avoid redeclaring the properties in MyProtocol within my class extension in order to implement MyProtocol privately?

  • Help moving multiple images at once with touches

    - by daveMac
    Here is my problem: I am trying to move a puzzle piece around the screen and then connect to the other piece if they are in close proximity. I have achieved this, though it is perhaps a little odd the way I did. My problem though is that once they have connected, I can't figure out how to move them as one image, instead of two separate entities. I would really appreciate any help or suggestions. Here is a sample of what I have been doing: (void)touchesMovedNSSet *)touches withEventUIEvent *)event{ UITouch *touch = [touches anyObject]; [self dispatchTouchEvent:[touch view] toPosition:[touch locationInView:self.view]]; } -(void)dispatchTouchEventUIView *)theView toPositionCGPoint)position{ if ((CGRectContainsPoint([picture frame], position))) { picture.center = position; } if (CGRectContainsPoint([picture2 frame], position)) { picture2.center = position; } }

    - by Josh
    I have a UITableView with a list of stories and a cell at the bottom that loads more stories. I am trying to make the "More Stories..." cell deselect and change its text to "Loading..." when clicked. I have searched all over the internet and all over stackoverflow and I cant figure out why my code isnt working right. Right now, when the "More Stories..." cell is clicked, it stays selected and doesnt ever change its text. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; if (storyIndex == [stories count]) { UITableViewCell *moreCell = [tableView dequeueReusableCellWithIdentifier:@"more"]; if (moreCell == nil) { moreCell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"more"] autorelease]; } // Set up the cell moreCell.textLabel.text = @"Loading..."; [tableView deselectRowAtIndexPath:indexPath animated:YES]; [self moreStories]; } else { NSLog(@"%@",[[stories objectAtIndex: storyIndex] objectForKey: @"link"]); webViewController *webController; webController = [[webViewController alloc] initWithURLPassed:[[stories objectAtIndex: storyIndex] objectForKey: @"link"]]; [self.navigationController pushViewController:webController animated:YES]; [webController release]; webController =nil; self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:nil action:nil]; } }

  • (iphone) How to access CGRect member variable inside c++ class?

    - by Eugene
    i have a c++ class with CGrect variable and i'm getting segfault when trying to access it. class Parent { //with some virtual functions/dtors }; class Child { public: void SetRect(CGRect rect) { mRect = rect; } CGRect GetRect() { return mRect; } int GetIndex() { return mIndex; } private: CGRect mRect; int mIndex; }; i'm doing CGRect rect = childPtr->GetRect(); from object c code and it segfaults. I printed *childPtr just before the call and rect looks fine with intended data value. int index = childPtr->GetIndex(); from same object c code(*.mm), works fine though. Any idea why I'm getting segfaults? Thank you edit - It's got something to do with virtual functions. (gdb) p singlePuzzlePiece-GetRect() Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000001 0x00000001 in ?? () Cannot access memory at address 0x1 The program being debugged was signaled while in a function called from GDB. GDB remains in the frame where the signal was received. To change this behavior use "set unwindonsignal on" Evaluation of the expression containing the function (at 0x1) will be abandoned. (gdb) Somehow, the function is not properly compiled?
