    <p>I'm trying to update an older (iOS4,5 era) app to iOS7 and am getting some compile/linker issues I can't figure out.</p> <p>I'm not sure the solution to the small subset of the compile errors pasted below. </p> <p>These issues appear to be from my usage of <a href="http://blog.shopsavvy.com/ios/sdk/documentation/" rel="nofollow">ScannerKit</a>. I was on version 4.2.1 and tried to update to the latest 4.3.0 but the issues remain. I defined have libScannerKit.a in my "Link Binary with Libraries" build phase.</p> <pre><code>Undefined symbols for architecture i386: "std::string::find(char, unsigned long) const", referenced from: zxing::oned::Code39Reader::decodeRow(int, zxing::Ref&lt;zxing::BitArray&gt;) in libScannerKit.a(Code39Reader.o) "std::string::substr(unsigned long, unsigned long) const", referenced from: zxing::oned::ConfigurableMultiFormatUPCEANReader::decodeRow(int, zxing::Ref&lt;zxing::BitArray&gt;) in libScannerKit.a(ConfigurableMultiFormatUPCEANReader.o) zxing::oned::MultiFormatUPCEANReader::decodeRow(int, zxing::Ref&lt;zxing::BitArray&gt;) in libScannerKit.a(MultiFormatUPCEANReader.o) zxing::oned::UPCAReader::maybeReturnResult(zxing::Ref&lt;zxing::Result&gt;) in libScannerKit.a(UPCAReader.o) zxing::oned::UPCEReader::convertUPCEtoUPCA(std::string) in libScannerKit.a(UPCEReader.o) "std::basic_stringbuf&lt;char, std::char_traits&lt;char&gt;, std::allocator&lt;char&gt; &gt;::str() const", referenced from: zxing::BitMatrix::description() in libScannerKit.a(BitMatrix.o) zxing::GridSampler::checkAndNudgePoints(zxing::Ref&lt;zxing::BitMatrix&gt;, std::vector&lt;float, std::allocator&lt;float&gt; &gt;&amp;) in libScannerKit.a(GridSampler.o) zxing::GF256Poly::description() const in libScannerKit.a(GF256Poly.o) zxing::datamatrix::DecodedBitStreamParser::decode(zxing::ArrayRef&lt;unsigned char&gt;) in libScannerKit.a(DecodedBitStreamParser-E74816B4CEA9EA3A.o) zxing::oned::Code128Reader::decodeRow(int, zxing::Ref&lt;zxing::BitArray&gt;) in libScannerKit.a(Code128Reader.o) zxing::qrcode::DecodedBitStreamParser::decodeByteSegment(zxing::Ref&lt;zxing::BitSource&gt;, std::string&amp;, int) in libScannerKit.a(DecodedBitStreamParser-B6EF2F7091225D41.o) zxing::qrcode::DecodedBitStreamParser::decodeNumericSegment(zxing::Ref&lt;zxing::BitSource&gt;, std::string&amp;, int) in libScannerKit.a(DecodedBitStreamParser-B6EF2F7091225D41.o) ... "std::ostream::flush()", referenced from: zxing::datamatrix::DataMatrixReader::decode(zxing::Ref&lt;zxing::BinaryBitmap&gt;) in libScannerKit.a(DataMatrixReader.o) </code></pre> <p>I'm trying to just update the app and make this newest release iOS7+ only. This project is old and it was original created in the early versions of XCode 4 so I dont know if there is some kind of vestigial config file issues or something. Or is this something where ScannerKit is built against i386 and I'm not including that arch in my build or something?</p> <p>If anyone is interested, <a href="https://gist.github.com/cpjolicoeur/7708763" rel="nofollow">here is a full gist of the compile errors</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
