以编程方式标识iphone设备

Question

我想识别安装了我的应用程序的设备。 这意味着，当我在iPhone上安装应用程序时，它应该告诉我设备信息。信息就像，设备是2G，3G或3GS。

目前，我只得到了型号，名称，系统名称，设备的systemVersion。

我想知道该设备是2G，3G或3GS。

请帮帮我。

Answer 1

在过去的Mac编程历史中，这总被认为是错误的问题。

你真正需要知道的是更具体的资料片。针对代码中的每个行为决策提出一个更狭窄的问题。例如，您可能需要知道设备是否具有GPS。另一个原因是你不应该决定如何使用基于它的模型设备的OpenGL堆栈，而是基于提供的OpenGL功能/扩展信息。

你现在得到的信息是从的UIDevice，这是一个不幸的是设计不良的API。它以最糟糕的格式为您提供完全错误的信息 - 字符串。

埃丽卡丧盾具有延伸到的UIDevice可能有用here。这只是sysctlbyname("hw.machine", ...)的包装。这个属性对于每个模型都是不同的。

但是，这通常是错误的问题。

这是我在我的应用程序使用，它的伟大工程

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; 
} 

希望它可以帮助

我做了这个，它甚至可以显示你的型号：

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"]) { 
     modelName = @"iPhone"; 
     modelnumber = @"A1203"; 
    } 
    else if([modelName isEqualToString:@"iPhone1,2"]) { 
     modelName = @"iPhone 3G"; 
     modelnumber = @"A1241/A1324"; 
    } 
    else if([modelName isEqualToString:@"iPhone2,1"]) { 
     modelName = @"iPhone 3GS"; 
     modelnumber = @"A1303/A1325"; 
    }
