For example, in the Chinese character range \ u4E00-\ u9FFF, the first one may be ha, and the last one may be ze, there is no way to associate the unicode of Chinese characters with pinyin, so there is only one huge dictionary to record the Pinyin of each Chinese character (or commonly used Chinese character.However, we can sort all Chinese Characters in pinyin order

technology.The industry's traditional approach is to adopt "Fuzzy matching " method to achieve " Association analysis ", namely: Audit system first audit out browser to Web server,Web Server-to-database server events, which are HTTP events, which are SQL events, then need to correlate these two events for a time series " Fuzzy match " This associates the Access resource account with the associated database operation.The advantages and disadvantages of this traditional approach are:Advantages:

Description: Cocoa provides nspredicate for specifying filtering criteria, which is a function that represents the calculation of true and false values in a computer, which is used somewhat like a SQL query condition, primarily for sorting out eligible objects from a collection, or for regular matching of strings. Definitions (most commonly used methods): Nspredicate *ca = [nspredicate predicatewithformat: (NSString *), ...]; Format:(1) comparison operator >,Available for numeric a

In WPF, Chinese characters are searched by pinyin, and Chinese characters are searched by wpf pinyin. 1. For a touch screen project in WPF, you need to enter a name, but the screen does not support Chinese character input. The use of the virtual keyboard is unstable. In order to solve this problem, we hereby handle it. 2. Create a new class conversion class, which initializes an array containing Pinyin and frequently used Chinese characters in pinyin. 3. Compare the corresponding Chinese charact
