IOS获取设备信息常用方法记录

1. 常用方法 GithubGist地址

常用方法

    NSLog(@"HostName: %@", [[NSProcessInfo processInfo] hostName]);
    //globallyUniqueString 唯一的标示符，每次调用都会不一样，可以用作一些临时缓存文件的名字
    NSLog(@"GlobalUniqueString: %@", [[NSProcessInfo processInfo] globallyUniqueString]);
    //操作系统名称
    NSLog(@"OperatingSystemName: %@", [[NSProcessInfo processInfo] operatingSystemName]);
    //操作系统版本
    NSLog(@"OperatingSystemVersion: %@", [[NSProcessInfo processInfo] operatingSystemVersionString]);
    //物理内存
    NSLog(@"PhysicalMem: %llu", [[NSProcessInfo processInfo] physicalMemory]);
    //进程名称
    NSLog(@"ProcessName: %@", [[NSProcessInfo processInfo] processName]);
    
    //供应商标识
    NSLog(@"UniqueId: %@", [UIDevice currentDevice].identifierForVendor);
    //设备类型（iPhone、iPad）
    NSLog(@"userInterfaceIdiom: %d", [UIDevice currentDevice].userInterfaceIdiom);
    //设备名字
    NSLog(@"Name: %@", [UIDevice currentDevice].name);
    //系统名字
    NSLog(@"SystemName: %@", [UIDevice currentDevice].systemName);
    //系统版本
    NSLog(@"SystemVersion: %@", [UIDevice currentDevice].systemVersion);
    //模型
    NSLog(@"Model: %@", [UIDevice currentDevice].model);
    //本地化的模型
    NSLog(@"LocalizeModel: %@", [UIDevice currentDevice].localizedModel);
    //电池状态
    NSLog(@"BatteryLevel: %f", [UIDevice currentDevice].batteryLevel);

2. 判断设备是否是7.0以上系统

[[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0f

注意：
假如我们的设备版本号为7.1.1（为字符串类型），对其进行floatValue浮点化后值为7.100000。

3. 判断设备是否是iPhone、iPad

• iPad：[[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad
• iPhone: [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone

UIUserInterfaceIdiom in UIDevice.h

typedef NS_ENUM(NSInteger, UIUserInterfaceIdiom) {
#if __IPHONE_3_2 <= __IPHONE_OS_VERSION_MAX_ALLOWED
    UIUserInterfaceIdiomPhone,           // iPhone and iPod touch style UI
    UIUserInterfaceIdiomPad,             // iPad style UI
#endif
};
