在开发中,需要获取当前设备的一些信息,可以通过UIDevice,NSbundle,NSlocale获取.
UIDevice
UIDevice 提供了多种属性,类函数及状态通知,可以检测手机电量,定位,感应,机型,当前系统版本等等.
//设备相关信息的获取
NSString *strName = [[UIDevice currentDevice] name];
NSLog(@"设备名称：%@", strName);//e.g. "My iPhone" NSString *strSysName = [[UIDevice currentDevice] systemName];
NSLog(@"系统名称：%@", strSysName);// e.g. @"iOS" NSString *strSysVersion = [[UIDevice currentDevice] systemVersion];
NSLog(@"系统版本号：%@", strSysVersion);// e.g. @"4.0" NSString *strModel = [[UIDevice currentDevice] model];
NSLog(@"设备模式：%@", strModel);// e.g. @"iPhone", @"iPod touch" NSString *strLocModel = [[UIDevice currentDevice] localizedModel];
NSLog(@"本地设备模式：%@", strLocModel);// localized version of model
NSBundle
bundle 是一个目录,其中包含了程序会使用到的资源,这些资源包含了图像,声音,编译好的代码,通过这些亦可获取一些应用信息.
/app应用相关信息的获取
NSDictionary *dicInfo = [[NSBundle mainBundle] infoDictionary];
// CFShow(dicInfo); NSString *strAppName = [dicInfo objectForKey:@"CFBundleDisplayName"];
NSLog(@"App应用名称：%@", strAppName); NSString *strAppVersion = [dicInfo objectForKey:@"CFBundleShortVersionString"];
NSLog(@"App应用版本：%@", strAppVersion); NSString *strAppBuild = [dicInfo objectForKey:@"CFBundleVersion"];
NSLog(@"App应用Build版本：%@", strAppBuild);
NSLocale
NsLocale可以获取用户的本地化信息,如货币,语言,国家,数字,日期格式,地理位置显示等等.
//Getting the User’s Language
NSArray *languageArray = [NSLocale preferredLanguages];
NSString *language = [languageArray objectAtIndex:];
NSLog(@"语言：%@", language);//en NSLocale *locale = [NSLocale currentLocale];
NSString *country = [locale localeIdentifier];
NSLog(@"国家：%@", country); //en_US
