ios - Scanning and capturing barcode with ZBar -

trying use zbar capture barcode. have following code in place @ moment. scanner shows, , appears scan barcode green overlay appears around code. don't know how capture decoded results.

i'm going wrong, thought i'd ask. nothing output console when scanning, don't think didreadsymbols being called @ all.

.h

@interface scannerviewcontroller : uiviewcontroller <zbarreaderdelegate> { }  @property (strong, nonatomic) iboutlet uilabel *readerresult; @property (strong, nonatomic) iboutlet uiview *readerview; @property (strong, nonatomic) iboutlet zbarreaderview *zbr; 

.m

- (void)viewdidload {     [super viewdidload];     // force class load may referenced directly nib     [zbarreaderviewcontroller class];      zbarreaderviewcontroller *reader= [zbarreaderviewcontroller new];     reader.readerdelegate = self;      zbarimagescanner *scanner = reader.scanner;     //reader.cameraoverlayview = self.readerview;     [scanner setsymbology: 0                           config: zbar_cfg_enable                               to: 1];     [reader setshowszbarcontrols:no];     [reader.readerview start];     self.zbr = reader.readerview;     [self.view addsubview:reader.view];  }  - (void) zbr: (zbarreaderview*) view      didreadsymbols: (zbarsymbolset*) syms           fromimage: (uiimage*) img {     nslog(@"scanner used");     //do useful results , display resulttext in resultviewcontroller     for(zbarsymbol *sym in syms) {         nslog(@"logged");         //return resulttext;         break;     } } 

any advice great. i'm getting confused @ moment. cheers.

when @ documentation zbar, i see delegate method signature is:

- (void) readerview:(zbarreaderview*)readerview didreadsymbols:(zbarsymbolset*)symbols fromimage:(uiimage*)image 

which not same thing have above. replace "zbr" "readerview" , delegate method should called.
