iOS Development Get mobile info (Uidevice,nsbundle,nslocale)

In development, it is necessary to obtain some information about the current device, which can be obtained through Uidevice,nsbundle,nslocale.

Uidevice

Uidevice provides a variety of properties, class functions and status notifications, which can detect cell phone power, positioning, sensing, model, current system version and so on.

Device-related information acquisition   nsstring *strname = [[Uidevice currentdevice] name];   NSLog (@ "Device name:%@", strName);//e.g. "My iPhone"       nsstring *strsysname = [[Uidevice currentdevice] systemName];   NSLog (@ "system name:%@", strsysname);//e.g. @ "IOS"      nsstring *strsysversion = [[Uidevice currentdevice] systemversion];   NSLog (@ "System version number:%@", strsysversion);//e.g. @ "4.0"      nsstring *strmodel = [[Uidevice currentdevice] model];   NSLog (@ "Device mode:%@", strmodel);//e.g. @ "IPhone" @ "IPod touch"      nsstring *strlocmodel = [[Uidevice Currentdevice] Localizedmodel];   

NSBundle　

A bundle is a directory that contains the resources the program uses, including images, sounds, compiled code, and some application information.

/app application-related information acquisition      nsdictionary *dicinfo = [[NSBundle mainbundle] infodictionary];    cfshow (dicinfo);            NSString *strappname = [Dicinfo objectforkey:@ "Cfbundledisplayname"];      NSLog (@ "app app Name:%@", strappname);            NSString *strappversion = [Dicinfo objectforkey:@ "cfbundleshortversionstring"];      NSLog (@ "app version:%@", strappversion);            NSString *strappbuild = [Dicinfo objectforkey:@ "cfbundleversion"];      

Nslocale　

Nslocale can obtain the user's localization information, such as currency, language, country, number, date format, location display and so on.
