[Software]_[windows]_[reference nsuserdefaults custom Windows Basuserdefaults]

Scene:

1. Under Mac Cocoa Development, you can use Nsuserdefaults to store configuration information easily, and it also supports complex types such as basic types of nsdictionary,nsarray. We use this class to store the runtime configuration,

such as multi-language options, check the update options, shortcut key settings, and so on. This information is automatically stored in the relevant location of the Bundleid.

Reference: http://blog.csdn.net/yepeng2014/article/details/49003753

This configuration is very important, if Windows is the only way to compare with it is the registry, but the registry is not easy to visually through the path to see, more trouble.

The SDK for Windows can really refer to cocoa and provide an API for developers to develop regular software.

2. Here the Nsuserdefaults interface is written in Windows version, currently only simple to store and read the string type, primitive type, object type, then return void*, because C + + does not have an ID type.

3. The main use of Rapidjson as a storage format, the relative nsuserdefaults XML format is slightly simpler, because JSON reads and writes very quickly.

4. It is software-independent and can be used across products.

Usage 1: Similar to nsuserdefaults using the default configuration, default profiles are created based on company name and product name

When the software starts:

Basuserdefaults::initstandarduserdefaults (Uiutilityproduct::getcorporationw (). C_STR (), UiUtilityProduct:: GETPRODUCTALIASW (). C_STR ());

When the software shuts down:

basuserdefaults* user = Basuserdefaults::standarduserdefaults (); User->writeall ();d elete user;

Use case 2: Read the configuration file packaged with the software, read-only.

wchar_t* install_dir_temp = Basutilityapp::getproductinstalldir (); std::wstring Url_path (install_dir_temp); url_ Path.append (L "Option.json"); Basuserdefaults::inituserdefaults ("url", Url_path.c_str ()); free (install_dir_temp);

Common Configuration files:

{    "help": "Http://www.xxx.com/online-help",    "purchase": "http://www.xxx.com/purchase/xxx.html",    " Usupport ":" http://www.xxx.com/support.html ",    " Color:toolbox:background ":" 217,250,243 ",    " Color:toolbar: Tab:font ":" 0,0,0 "}
