    UIDevice类展示了一些关键的特定于设备的属性，包括使用的iPhone ,Ipad或iPod Touch型号、设备名称、以及OS名称和版本。
    他是一种一站式解决方案，用于提取出某些系统详细信息。每个方法都是一个实例方法，他们是使用UIDevice单例通过[UIDevice currentDevice]调用的。
    可以通过UIDevice获取的系统信息包括下面的这些项。

    • 1.systemName:它用于返回当前使用的操作系统的名称。对于目前这一代IOS设备，在平台上只运行一种OS:iPhone OS.
    • 2.systemVersion:这个值将列出单元上目前安装的固定版本。
    • 3.model:iPhone 型号返回一个描述其平台的字符串，既iPhone、iPad和iPod Touch.如果将IOS扩展到新设备上，将使用额外的字符串描述这些型号。localizedModel提供了该属性的本地化版本。
    • 4.userInterfaceIdiom:这个属性表示当前设备上使用的界面风格，既iPhone或iPad.当Apple提供另外的平台风格时，可能会引入其他的用语。
    • 5.name:这个字符串由用户指定的iPhone名称，这个名称也用于创建设备的本地主机名。
    UIDevice *device = [UIDevice currentDevice];
NSLog(@"systemName :%@",device.systemName);
NSLog(@"systemVersion :%@",device.systemVersion);
NSLog(@"model :%@",device.model);
NSLog(@"localizedModel:%@",device.localizedModel);
NSLog(@"userInterfaceIdiom:%d",device.userInterfaceIdiom);
NSLog(@"name:%@",device.name);

输出:
systemName :iPhone OS
systemVersion :8.1.2
model :iPhone
localizedModel:iPhone
userInterfaceIdiom:0
name:“xxxx”的 iPhone

    主要用法：获取设备唯一标识

    思路：通过keychain缓存，没有的话生成一串随机值。

    UIDevice (Extention)
- (NSString *)zl_deviceId {
    static NSString *deviceId;
    static dispatch_once_t onceToken;

    dispatch_once(&onceToken, ^{
        deviceId = [KeychainWrapper keychainStringFromMatchingIdentifier:@"zl_deviceId"];

        if (!deviceId) {
            deviceId = [[self identifierForVendor] UUIDString];

            if (deviceId) {
                [KeychainWrapper createKeychainValue:deviceId forIdentifier:@"zl_deviceId"];
            } else {
                NSAssert(0, @"Device ID not found");
                deviceId = [self randomDeviceId];
            }
        }
    });
    return deviceId;
}

- (void)removeKeychainDeviceId {
    [KeychainWrapper deleteItemFromKeychainWithIdentifier:@"zl_deviceId"];
}

- (NSString *)randomDeviceId {
    生成一个随机字符串
    return uniqueId;
}

    一个专门生产32位的uuid的包

    主要用法：

    #import <UIKit/UIKit.h>
