UIDevice
UIDevice提供了多种属性、类函数及状态通知，帮助我们全方位了解设备状况。从检测电池电量到定位设备与临近感应，UIDevice所做的工作就是为应用程序提供用户及设备的一些信息。UIDevice类还能够收集关于设备的各种具体细节，例如机型及iOS版本等。其中大部分属性都对开发工作具有积极的辅助作用。下面的代码简单的使用UIDevice获取手机属性。
//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 *strId = [[UIDevice currentDevice] uniqueIdentifier];
NSLog(@"设备唯一标识：%@", strId);//UUID,5.0后不可用
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
CGFloat batteryLevel=[[UIDevice currentDevice] batteryLevel]; // 电池电量
NSBundle
bundle是一个目录,其中包含了程序会使用到的资源. 这些资源包含了如图像,声音,编译好的代码,nib文件(用户也会把bundle称为plug-in). 对应bundle,cocoa提供了类NSBundle.一个应用程序看上去和其他文件没有什么区别. 但是实际上它是一个包含了nib文件,编译代码,以及其他资源的目录. 我们把这个目录叫做程序的main bundle。通过这个路径可以获取到应用的信息，例如应用名、版本号等。
//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设置，例如货币类型，国家，语言，数字，日期格式的格式化，提供正确的地理位置显示等等。下面的代码获取机器当前语言和国家代码。
//Getting the User’s Language
NSArray *languageArray = [NSLocale preferredLanguages];
NSString *language = [languageArray objectAtIndex:0];
NSLog(@"语言：%@", language);//en
NSLocale *locale = [NSLocale currentLocale];
NSString *country = [locale localeIdentifier];
NSLog(@"国家：%@", country); //en_US
手机类型：如：iPhone 6 需要导入头文件：#import <sys/utsname.h>
NSString* phoneModel = [self iphoneType];//方法在下面：
- (NSString *)iphoneType {
struct utsname systemInfo;
uname(&systemInfo);
NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];
if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";
if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";
if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4";
if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4";
if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
if ([platform isEqualToString:@"iPhone5,2"]) return @"iPhone 5";
if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5c";
if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5c";
if ([platform isEqualToString:@"iPhone6,1"]) return @"iPhone 5s";
if ([platform isEqualToString:@"iPhone6,2"]) return @"iPhone 5s";
if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus";
if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6";
if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";
if ([platform isEqualToString:@"iPhone8,4"]) return @"iPhone SE";
if ([platform isEqualToString:@"iPhone9,1"]) return @"iPhone 7";
if ([platform isEqualToString:@"iPhone9,2"]) return @"iPhone 7 Plus";
if ([platform isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G";
if ([platform isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G";
if ([platform isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G";
if ([platform isEqualToString:@"iPod4,1"]) return @"iPod Touch 4G";
if ([platform isEqualToString:@"iPod5,1"]) return @"iPod Touch 5G";
if ([platform isEqualToString:@"iPad1,1"]) return @"iPad 1G";
if ([platform isEqualToString:@"iPad2,1"]) return @"iPad 2";
if ([platform isEqualToString:@"iPad2,2"]) return @"iPad 2";
if ([platform isEqualToString:@"iPad2,3"]) return @"iPad 2";
if ([platform isEqualToString:@"iPad2,4"]) return @"iPad 2";
if ([platform isEqualToString:@"iPad2,5"]) return @"iPad Mini 1G";
if ([platform isEqualToString:@"iPad2,6"]) return @"iPad Mini 1G";
if ([platform isEqualToString:@"iPad2,7"]) return @"iPad Mini 1G";
if ([platform isEqualToString:@"iPad3,1"]) return @"iPad 3";
if ([platform isEqualToString:@"iPad3,2"]) return @"iPad 3";
if ([platform isEqualToString:@"iPad3,3"]) return @"iPad 3";
if ([platform isEqualToString:@"iPad3,4"]) return @"iPad 4";
if ([platform isEqualToString:@"iPad3,5"]) return @"iPad 4";
if ([platform isEqualToString:@"iPad3,6"]) return @"iPad 4";
if ([platform isEqualToString:@"iPad4,1"]) return @"iPad Air";
if ([platform isEqualToString:@"iPad4,2"]) return @"iPad Air";
if ([platform isEqualToString:@"iPad4,3"]) return @"iPad Air";
if ([platform isEqualToString:@"iPad4,4"]) return @"iPad Mini 2G";
if ([platform isEqualToString:@"iPad4,5"]) return @"iPad Mini 2G";
if ([platform isEqualToString:@"iPad4,6"]) return @"iPad Mini 2G";
if ([platform isEqualToString:@"i386"]) return @"iPhone Simulator";
if ([platform isEqualToString:@"x86_64"]) return @"iPhone Simulator";
return platform;
