UIDevice获取设备数据以及如何获取应用信息

// 硬件信息
[UIDevice platform];//平台
[UIDevice cpuFrequency]];//cpu信息
UIDevice busFrequency]];//总线
[UIDevice totalMemory]];//总内存
UIDevice userMemory]];//已经使用的内存

//设备相关信息的获取

    NSString *strName = [[UIDevice currentDevice] name];
    NSLog(@"设备名称：%@", strName);
    
    NSString *strId = [[UIDevice currentDevice] uniqueIdentifier];
    NSLog(@"设备唯一标识：%@", strId);
    
    NSString *strSysName = [[UIDevice currentDevice] systemName];
    NSLog(@"系统名称：%@", strSysName);
    
    NSString *strSysVersion = [[UIDevice currentDevice] systemVersion];
    NSLog(@"系统版本号：%@", strSysVersion);
    
    NSString *strModel = [[UIDevice currentDevice] model];
    NSLog(@"设备模式：%@", strModel);
    
    NSString *strLocModel = [[UIDevice currentDevice] localizedModel];
    NSLog(@"本地设备模式：%@", strLocModel);
    
    float version = [[[UIDevice currentDevice] systemVersion] floatValue];
    NSLog(@"版本号：%f\n", version);
    
    //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);
