可编程识别 iPhone 设备

Question

我想识别应用程序所安装的设备。也就是说，当我在iPhone上安装应用程序时，它应该告诉我设备信息。这些信息包括设备是2G、3G还是3GS。

目前，我只能获取设备的型号、名称、系统名称和系统版本。

我想知道设备是2G、3G还是3GS。

请帮助我。

在Mac编程的过去历史中，这被认为是错误的问题。真正需要知道的是更具体的信息。针对代码中的每个行为决策，提出更加狭窄的问题。例如，您可能需要知道设备是否具有GPS功能。另一个例子是，您不应基于设备型号来决定如何使用OpenGL堆栈，而应该基于提供的OpenGL能力/扩展信息来进行决定。您现在获取的信息来自UIDevice，这是一个设计不良的API。它以最糟糕的格式 - 字符串，向您提供完全错误的信息。Erica Sadun有一个扩展程序可以用于UIDevice 这里。它只是sysctlbyname("hw.machine",...)的包装器。此属性对于每个模型都不同。但是再次强调，通常这是错误的问题。

同意。除非你在开发一个可以清点公司机群中不同iPhone设备的应用，需要对它们进行排序，否则你可能并不需要知道它是3G还是3Gs，而更需要知道它是否支持你想要使用的功能。使用AvailibilityMacros来查找该设备是否支持你需要的功能。 - mahboudz

这是我在我的应用程序中使用的，效果非常好。

NSString *deviceType = [UIDevice currentDevice].model;
NSLog(@"DEVICE TYPE %@", deviceType);

struct utsname systemInfo;
uname(&systemInfo);

  - (NSString *) platformString{
NSString *platform =  [NSString stringWithCString:systemInfo.machine
                                     encoding:NSUTF8StringEncoding];    
NSLog(@"type ...%@", platform);


if ([platform isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";
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:@"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:@"iPad1,1"])      return @"iPad";
if ([platform isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
if ([platform isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
if ([platform isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
if ([platform isEqualToString:@"i386"])         return @"Simulator";
return platform;
}

希望这会有所帮助。

我做了这个，它甚至能显示出型号编号：

struct utsname systemInfo;
    uname(&systemInfo);

    NSString *modelName = [NSString stringWithCString:systemInfo.machine
                                             encoding:NSUTF8StringEncoding];

    NSString *machinename = [NSString stringWithCString:systemInfo.machine
                                               encoding:NSUTF8StringEncoding];


    NSString *modelnumber = @"Not listed";

    //Simulator
    if([modelName isEqualToString:@"i386"] || [modelName isEqualToString:@"x86_64"]) {
        modelName = @"iPhone Simulator";
        modelnumber = @"XXXXX";

    }

    //iPhone
    else if([modelName isEqualToString:@"iPhone1,1"]) {

    }
    else if([modelName isEqualToString:@"iPhone1,2"]) {
        modelName = @"iPhone 3G";
        modelnumber = @"A1241/A1324";
    }
    else if([modelName isEqualToString:@"iPhone2,1"]) {
