以編程方式標識iphone設備

Question

我想識別安裝了我的應用程序的設備。 這意味着，當我在iPhone上安裝應用程序時，它應該告訴我設備信息。信息就像，設備是2G，3G或3GS。

目前，我只得到了型號，名稱，系統名稱，設備的systemVersion。

我想知道該設備是2G，3G或3GS。

請幫幫我。

Answer 1

在過去的Mac編程歷史中，這總被認爲是錯誤的問題。

你真正需要知道的是更具體的資料片。針對代碼中的每個行爲決策提出一個更狹窄的問題。例如，您可能需要知道設備是否具有GPS。另一個原因是你不應該決定如何使用基於它的模型設備的OpenGL堆棧，而是基於提供的OpenGL功能/擴展信息。

你現在得到的信息是從的UIDevice，這是一個不幸的是設計不良的API。它以最糟糕的格式爲您提供完全錯誤的信息 - 字符串。

埃麗卡喪盾具有延伸到的UIDevice可能有用here。這只是sysctlbyname("hw.machine", ...)的包裝。這個屬性對於每個模型都是不同的。

但是，這通常是錯誤的問題。

這是我在我的應用程序使用，它的偉大工程

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; 
} 

希望它可以幫助

我做了這個，它甚至可以顯示你的型號：

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"]) {
