3.9. ZBarSymbolSet Class Reference

class ZBarSymbolSet

Inherits from:NSObject Conforms to:NSFastEnumeration

A symbol set is a simple container for the symbols scanned from an image. It supports NSFastEnumeration, and not much else... Use it to iterate through the ZBarSymbol objects in a decode result set:

ZBarSymbolSet *symbols = image.symbols;
for(ZBarSymbol *symbol in symbols) {
    // process result
}

This class is a simple wrapper around a zbar_symbol_set_t C object (q.v.)
