Use ZBar in iOS to scan the QR code and customize the scan interfaceZXing has been used in Android to identify QR codes. ZXing also has the corresponding iOS version. After understanding it, ZBar is also a common QR code recognition software, the sdks for iOS and Android are provided for use. Finally, I chose ZBar for QR code identification. The annotations are clear and easy to use.ZBar provides two usage

oracle| Index In oracle9i we know that we can use the Jump Index Scan (index Skip Scan). However, there are some limitations to the use of jumping index scans. From Oracle's documentation we can find this: Index Skip Scans Index skip scans improve index scans by Nonprefix columns. Often, scanning index blocks is faster than scanning table data blocks. Skip scanning lets a composite index is split logical

In our zxing framework for the two-dimensional code scanning, we will find that the mobile phone with the resolution of the increase, the scan box will be smaller, in 1920*1280 and 1280*720 is relatively normal, but Samsung's several mobile phones note4,5,s6, and other mobile phone resolution of up to 2560 *1440, even some mobile phones up to 3660 of the bar can't remember.When these phones scan, pop-up

Generally, there are only two basic data access methods: Full scan or index scan. During the full scan, multiple blocks are read into one Io operation. Index scanning first scans the leaf blocks of the index to obtain specific row IDs, and then uses these row IDs to access the parent table to obtain actual data. Full scan
