What to replace [reader dismissModalViewControllerAnimated :NO with? - ios

Question

I am using XCode v.4.6 and I am trying to make an app that uses a QR Code scanner. I have followed a tutorial on this page ( http://iphonenativeapp.blogspot.com/2011/07/qr-code-readerscanner-for-iphone-app-in.html ) and have copied and pasted this code:
#import "QRscannerFirstViewController.h"
#interface QRscannerFirstViewController ()
#end
#implementation QRscannerFirstViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = NSLocalizedString(#"First", #"First");
self.tabBarItem.image = [UIImage imageNamed:#"first"];
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#import "QRscannerFirstViewController.h"
#end
#implementation QRscannerViewController
#synthesize imgPicker,resultTextView;
-(IBAction)StartScan:(id) sender{
ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.readerDelegate = self;
reader.readerView.torchMode = 0;
ZBarImageScanner *scanner = reader.scanner;
// TODO: (optional) additional reader configuration here
// EXAMPLE: disable rarely used I2/5 to improve performance
[scanner setSymbology: ZBAR_I25
config: ZBAR_CFG_ENABLE
to: 0];
// present and release the controller
[self presentModalViewController: reader
animated: YES];
resultTextView.hidden=NO;
}
- (void) readerControllerDidFailToRead: (ZBarReaderController*) reader
withRetry: (BOOL) retry{
NSLog(#"the image picker failing to read");
}
- (void) imagePickerController: (UIImagePickerController*) reader didFinishPickingMediaWithInfo: (NSDictionary*) info
{
NSLog(#"the image picker is calling successfully %#",info);
// ADD: get the decode results
id<NSFastEnumeration> results = [info objectForKey: ZBarReaderControllerResults];
ZBarSymbol *symbol = nil;
NSString *hiddenData;
for(symbol in results)
hiddenData=[NSString stringWithString:symbol.data];
NSLog(#"the symbols is the following %#",symbol.data);
// EXAMPLE: just grab the first barcode
// break;
// EXAMPLE: do something useful with the barcode data
//resultText.text = symbol.data;
resultTextView.text=symbol.data;
NSLog(#"BARCODE= %#",symbol.data);
NSUserDefaults *storeData=[NSUserDefaults standardUserDefaults];
[storeData setObject:hiddenData forKey:#"CONSUMERID"];
NSLog(#"SYMBOL : %#",hiddenData);
resultTextView.text=hiddenData;
[reader dismissModalViewControllerAnimated: NO];
}
#end
into my .m file. When I put this code ino the editor, I get a warning saying how this
[reader dismissModalViewControllerAnimated: NO];
and this
[self presentModalViewController: reader
animated: YES];
has been decapricated in IOS 6.0.
When I run my application and press a button that starts the QR Scanner, my application quits and it gives me the
Thread 1: signal SIGABRT
error and highlights
return UIApplicationMain(argc, argv, nil, NSStringFromClass([QRscannerAppDelegate class]));
What is recommended for replacing this and how should I fix this error?

Answer 1

Here you go
[self presentViewController:reader animated:YES completion:Nil];
[reader dismissViewControllerAnimated:NO completion:Nil];

Answer 2

Use [self presentViewController:reader animated:YES completion:nil]; and [reader dismissViewControllerAnimated:NO completion:nil];
