• UIAlertViewDelegate method didDismissWithButtonIndex gets called while the phone is sleeping/locked.

  - by Rob

  I have a UIAlertView who's didDismissWithButtonIndex delegate method calls pops the view controller (same class, it's the alertview delegate and the viewcontroller) to return the user to the previous screen. The issue is that when you lock the phone before the [alert show]; is called, something is calling didDismissWithButtonIndex while the phone is locked. Since the response to that is to pop the view controller, which releases and deallocs it, I crash on the callback. What is causing this phantom button press? Seems like a framework bug, but I hate jumping to that conclusion. I'm definitely not hitting the button, because I hit a breakpoint in my code right before it's displayed. Then I lock the phone. Then I continue. I see it do the show, return to the event loop, and then, while the phone is still locked, hit my breakpoint in didDismissWithButtonIndex. There are a few internet/forum postings about similar spurious delegate calls, but no concrete answers. This is on the simulator, and the device, both OS 2.2 and OS 3.0. I'm assuming I'm missing something, but what? Update: Yeah, I created a simple project with just two view controllers, where when the 2nd view controller displays it creates the alert, and shows it. Then I NSLog in the delegate method, and when the phone is locked, it fires once while locked, and then again when it's unlocked and the button is clicked...2 log messages. But when not locked, there's only one. I guess I'll open an issue, but it seems awfully obvious to have survived this long without anyone complaining. :-) I'm going to try and work around it by making an isActive flag value when the willResignActive/didBecomeActive notifications arrive, and if the app isn't active skipping the delegate body. Update I went ahead in July after I posted this and created radar 7097363 for this issue. There's been no response. The workaround in practice works quite well, checking the active status when processing the delegate, and skipping the action if the the app is inactive.

• Playing videos in UIWebView broken in iOS4?

  - by rforte

  I have an app that's worked since version 2.0 of the SDK where I create and add a UIWebView and then load the URL of an .mov to play a movie. Ever since the early version of the 4.0 beta up until the 4.0 GM this has stopped working. When I load a movie now I get the following error: :Plug-in handled load" and the movie never displays. Is this a known issue? Am I doing something wrong in 4.0?

• How do you hide/show UISearchBar's scope bar with animation?

  - by zekel

  I want to show no scope bar when the table is empty (before the search bar edits for the first time), no scope bar when it's editing, and finally show it when editing done. I know about the UISearchBarDelegate protocol, but I don't know how to show/hide the scope bar with animation. I know UISearchBar has setShowsScopeBar:, but no setShowsScopeBar:animated: the way it does for setShowsCancelButton:animated.

• UIWebView not loading URL

  - by jerincbus

  I'm having trouble getting a UIWebView to load a URL that I'm sending to it. Before I get into my code I was wondering if URL has to start with "http://" or can it start with "www."? I'm using an IBAction to push a UIView on to the stack: (IBAction)goToWebView { WebViewController *webController = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:[NSBundle mainBundle]]; //set the strings webController.webTitle = [self Title]; webController.webURL = [self website]; //Push the new view on the stack [[self navigationController] pushViewController:webController animated:YES]; [webController release]; webController = nil; } Then here is my WebViewController.h file: @interface WebViewController : UIViewController { IBOutlet UIWebView *webView; NSString *webTitle; NSString *webURL; } @property (nonatomic, retain) IBOutlet UIWebView *webView; @property (nonatomic, retain) NSString *webTitle; @property (nonatomic, retain) NSString *webURL; here And my WebViewController.m file: - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = webURL; //Create a URL object. NSURL *url = [NSURL URLWithString:urlAddress]; //URL Requst Object NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; //Load the request in the UIWebView. [webView loadRequest:requestObj]; }

• UIButton doesn't listen to content mode setting?

  - by Dan Ray

  firstButton is a UIButton of type Custom. I'm programmatically putting three of them across each cell of a table, thusly: [firstButton setImage:markImage forState:UIControlStateNormal]; [firstButton setContentMode:UIViewContentModeScaleAspectFit]; [cell.contentView addSubview:firstButton]; Elsewhere, I'm telling it to clipToBounds. What I get is a crop of the center square of the image, rather than an aspect-scaled rendering of it. I've tried this lots of ways, including setting the mode property on firstButton.imageView, which also doesn't seem to work.

• Customizing UIPickerView

  - by Raj

  Hi all, I have a requirement where UIPickerView should be customized. The picker view should look something like this: The application which has customized the pickerView similarly is: http://itunes.apple.com/us/app/convert-the-unit-calculator/id325758140?mt=8 I have tried removing the default pickerView selection bar by resetting the property showsSelectionIndicator of UIImagePicker and adding a overlay view. But the problem is, the overlay view should be transparent so that the wheel behind it is visible. But the other application somehow does it even though the selection bar is not transparent. Any ideas on how to achieve this feat? Thanks and Regards, Raj

• how do we access values stored in NSMutableArray of NSMutableDictionary ?

  - by srikanth rongali

  I have stored values in NsMutableDictionaries . ThenI stored all the dictionaries in NSMutable Array. I need to access the values ?

• Using NSNumberFormatter to get a decimal value from an international currency string

  - by Duncan A

  It seems that the NSNumberFormatter can't parse Euro (and probably other) currency strings into a numerical type. Can someone please prove me wrong. I'm attempting to use the following to get a numeric amount from a currency string: NSNumberFormatter *currencyFormatter = [[[NSNumberFormatter alloc] init] autorelease]; [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; NSNumber *currencyNumber = [currencyFormatter numberFromString:currencyString]; This works fine for UK and US currency amounts. It even deals with $ and £ and thousands separators with no problems. However, when I use it with euro currency amounts (with the Region Format set to France or Germany in the settings app) it returns an empty string. All of the following strings fail: 12,34 € 12,34 12.345,67 € 12.345,67 It's worth noting that these strings match exactly what comes out of the NSNumberFormatter's stringFromNumber method when using the corresponding locale. Setting the Region Format to France in the settings app, then setting currencyNumber to 12.34 in the following code, results in currencyString being set to '12,34 €' : NSNumberFormatter *currencyFormatter = [[[NSNumberFormatter alloc] init] autorelease]; [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; NSString *currencyString = [currencyFormatter stringFromNumber:currencyNumber]; It would obviously be fairly easy to hack around this problem specifically for the Euro but I'm hoping to sell this app in as many countries as possible and I'm thinking that a similar situation is bound to occur with other locales. Does anyone have an answer? TIA, Duncan

• Size of static libraries generated by XCode

  - by shaft80

  I have a project tree in XCode that looks like this: AppProject depends on ObjcWrapper that in turn depends on PureCppLib. ObjcWrapper and PureCppLib are static library projects. Combined, all sources barely reach 15k lines of code, and, as expected, the size of resulting binary is about 750Kb in release mode and slightly over 1Mb in debug mode. So far, so good. However, ObjcWraper.a and PureCppLib.a are over 6Mb each in either mode. So the first question is why it is so. But more importantly, how can I ensure that those static libs do not include parts or all of the source code? Thanks in advance!

• Cocos2D Director Pause/Resume Issue

  - by Aditya

  I am trying to play a .gif animation in cocos2D. For this i am using the library glgif. Now, to display the animation i am pausing the Director, adding a subview to show the animation and after the animation is done i am resuming the Director. However, I am not able to resume the state of the Director and it shows blank. So I tried this without pausing and resuming this Director and it still did not work.I also tried detaching the director before tha animation and adding it back afterwards and even that did not work. So is there a way to pause/suspend the Director in the application and properly restore is back? Thanks. Code sample: [[Director sharedDirector] pause]; [[Director sharedDirector] detach]; AppDelegate *del = [[UIApplication sharedApplication] delegate]; [del.window addSubview:del.viewController.view]; [del.window makeKeyAndVisible]; // this is code to call glgif class and start anim. //code to resume the director AppDelegate *del = [[UIApplication sharedApplication] delegate]; [[Director sharedDirector] resume]; [[Director sharedDirector] attachInView:del.window]; MScene *m = [MScene node]; [[Director sharedDirector] replaceScene:m];

  I've added a button as an accessory view to uitableviewcell, and I when I press it, I'd like to be able to access the index path of the table view cell it's currently inside of so I can delete/modify the contents of that cell.

Any help would be greatly appreciated. Sorry if this is a noobie question.

  Hi, i added a Tab bar to my existing view called secondViewController where there are now 4 tab bar items using interface builder. This tab bar will allow the users to switch between views. This is what ive tried to do: If i use a tabbar controller, then a new view pops up and i dont want that. i simply want to be able to add a tab bar as ive done and carry on from there. i dont know how to actually connect it all up and make everything work together. This is what i understand: i have to make my current - secondViewController an tabbardelegate which is what ive done as shown @interface paddedDholViewController : UIViewController <AVAudioPlayerDelegate, UITabBarDelegate> { } then i understand that i have to add tabBar.delegate = self; for me to be able to detect the tabBar:didSelectItem: so i can then implement something like this - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { if ([viewController.tabBarItem.title isEqualToString:@"FIRST"]) { NSLog(@"FIRST"); } else if ([viewController.tabBarItem.title isEqualToString:@"SECOND"]) { NSLog(@"SECOND"); } } to be able to switch between the views The thing is as ive said before i dont know how to implement all of this and how to connect everything up. can someone help me please.

Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Custom initialization } return self; } */ - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } /* // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } */ /* // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return (interfaceOrientation == UIInterfaceOrientationPortrait); } */ - (void)drawRect:(CGRect)rect { CGContextRef ctx = UIGraphicsGetCurrentContext(); CGContextClearRect(ctx, rect); //CGContextSetCMYKFillColor(ctx, 35.0, 56.0, 34.0, 30.0, 1.0); //CGContextSetRGBFillColor(ctx, 92.0f, 95.0f, 97.0f, 1.0f); //CGContextFillRect(ctx, CGRectMake(0, 0, 300, 280)); CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextSetLineWidth(ctx, 2.0); float fltX1,fltX2,fltY1,fltY2=0; NSArray *hoursInDays = [[NSArray alloc] initWithObjects:@"0",@"1" ,@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"11",@"12", nil]; fltX1 = 30; fltY1 = 5; fltX2 = fltX1; fltY2 = 270; //Dividing the Y-axis CGContextMoveToPoint(ctx, fltX1, fltY1); CGContextAddLineToPoint(ctx, fltX2, fltY2); //float y = 275; for(int intIndex = 0 ; intIndex < [hoursInDays count] ; fltY2-=20, intIndex++) { CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextMoveToPoint(ctx, fltX1-3 , fltY2); CGContextAddLineToPoint(ctx, fltX1+3, fltY2); CGContextSelectFont(ctx, "Helvetica", 14.0, kCGEncodingMacRoman); CGContextSetTextDrawingMode(ctx, kCGTextFill); CGContextSetRGBFillColor(ctx, 0, 255, 255, 1); CGAffineTransform xform = CGAffineTransformMake( 1.0, 0.0, 0.0, -1.0, 0.0, 0.0); CGContextSetTextMatrix(ctx, xform); const char *arrayDataForYAxis = [[hoursInDays objectAtIndex:intIndex] UTF8String]; CGContextShowTextAtPoint(ctx, fltX1-18, fltY2-18 , arrayDataForYAxis, strlen(arrayDataForYAxis)); CGContextStrokePath(ctx); } CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextSetLineWidth(ctx, 2.0); fltX1 = 5; fltY1 = 250; fltX2 = 270; fltY2 = fltY1; NSArray *weekDays =[[NSArray alloc] initWithObjects:@"Sun", @"Mon", @"Tus", @"Wed", @"Thu", @"Fri", @"Sat", nil]; //Dividing the X-axis CGContextMoveToPoint(ctx, fltX1, fltY1); CGContextAddLineToPoint(ctx, fltX2, fltY2); //float y = 275; for(int intIndex = 0 ; intIndex < [weekDays count] ; fltX1+=33, intIndex++) { CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextMoveToPoint(ctx, fltX1+52 , fltY2-3); CGContextAddLineToPoint(ctx, fltX1+52, fltY2+3); CGContextSelectFont(ctx, "Arial", 15.0, kCGEncodingMacRoman); CGContextSetTextDrawingMode(ctx, kCGTextFill); CGContextSetRGBFillColor(ctx, 0, 255, 255, 1); CGAffineTransform xform = CGAffineTransformMake( 1.0, 0.0, 0.0, -1.0, 0.0, 0.0); CGContextSetTextMatrix(ctx, xform); const char *arrayDataForXAxis = [[weekDays objectAtIndex:intIndex] UTF8String]; CGContextShowTextAtPoint(ctx, fltX1+37, fltY2+18 , arrayDataForXAxis, strlen(arrayDataForXAxis)); CGContextStrokePath(ctx); } } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview.

• Using NSURLRequest to pass key-value pairs to PHP script with POST

  - by Ralf Mclaren

  Hi, I'm fairly new to objective-c, and am looking to pass a number of key-value pairs to a PHP script using POST. I'm using the following code but the data just doesn't seem to be getting posted through. I tried sending stuff through using NSData as well, but neither seem to be working. NSDictionary* data = [NSDictionary dictionaryWithObjectsAndKeys: @"bob", @"sender", @"aaron", @"rcpt", @"hi there", @"message", nil]; NSURL *url = [NSURL URLWithString:@"http://myserver.com/script.php"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[NSData dataWithBytes:data length:[data count]]]; NSURLResponse *response; NSError *err; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err]; NSLog(@"responseData: %@", content); This is getting sent to this simple script to perform a db insert: <?php $sender = $_POST['sender']; $rcpt = $_POST['rcpt']; $message = $_POST['message']; //script variables include ("vars.php"); $con = mysql_connect($host, $user, $pass); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("mydb", $con); mysql_query("INSERT INTO php_test (SENDER, RCPT, MESSAGE) VALUES ($sender, $rcpt, $message)"); echo "complete" ?> Any ideas?
