Just a Computer Graphics Studio & My Life

原先以為想知道設備資訊 (Device Information),使用原生SDK應該就足夠了,但是很可惜沒有⋯⋯像是我想知道設備是iPhone 6iPhone 6+,目前沒有API可以呼叫取得,僅可取得iPhone,沒有任何版本識別。

慶幸還有偉大的第三方套件,省去我研究撰寫的時間!

UIDeviceHardware – Determine iOS device being used

之所以想知道設備型號,是因為要傳回server,記錄使用者點擊任何功能的狀況,所以想必那些統計平台都用了類似的方法實作~

很簡單地建立兩個檔案 (.h和.m):

UIDeviceHardware.h


#import <Foundation/Foundation.h>
@interface UIDeviceHardware : NSObject 

- (NSString *) platform;
- (NSString *) platformString;

@end

UIDeviceHardware.m


#import "UIDeviceHardware.h"
#include <sys/types.h>
#include <sys/sysctl.h>

@implementation UIDeviceHardware

- (NSString *) platform{
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithUTF8String:machine];
    free(machine);
    return platform;
}

- (NSString *) platformString{
    NSString *platform = [self 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:@"iPhone3,2"])    return @"iPhone 4";
    if ([platform isEqualToString:@"iPhone3,3"])    return @"Verizon iPhone 4";
    if ([platform isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
    if ([platform isEqualToString:@"iPhone5,1"])    return @"iPhone 5 (GSM)";
    if ([platform isEqualToString:@"iPhone5,2"])    return @"iPhone 5 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPhone5,3"])    return @"iPhone 5C (GSM)";
    if ([platform isEqualToString:@"iPhone5,4"])    return @"iPhone 5C (GSM+CDMA)";
    if ([platform isEqualToString:@"iPhone6,1"])    return @"iPhone 5S (GSM)";
    if ([platform isEqualToString:@"iPhone6,2"])    return @"iPhone 5S (GSM+CDMA)";
    if ([platform isEqualToString:@"iPhone7,1"])    return @"iPhone 6+";
    if ([platform isEqualToString:@"iPhone7,2"])    return @"iPhone 6";

    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:@"iPod5,1"])      return @"iPod Touch 5G";

    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:@"iPad2,4"])      return @"iPad 2 (WiFi)";
    if ([platform isEqualToString:@"iPad2,5"])      return @"iPad Mini (WiFi)";
    if ([platform isEqualToString:@"iPad2,6"])      return @"iPad Mini (GSM)";
    if ([platform isEqualToString:@"iPad2,7"])      return @"iPad Mini (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad3,1"])      return @"iPad 3 (WiFi)";
    if ([platform isEqualToString:@"iPad3,2"])      return @"iPad 3 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad3,3"])      return @"iPad 3 (GSM)";
    if ([platform isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";
    if ([platform isEqualToString:@"iPad3,5"])      return @"iPad 4 (GSM)";
    if ([platform isEqualToString:@"iPad3,6"])      return @"iPad 4 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad4,1"])      return @"iPad Air (WiFi)";
    if ([platform isEqualToString:@"iPad4,2"])      return @"iPad Air (Cellular)";
    if ([platform isEqualToString:@"iPad4,3"])      return @"iPad Air";
    if ([platform isEqualToString:@"iPad4,4"])      return @"iPad Mini 2G (WiFi)";
    if ([platform isEqualToString:@"iPad4,5"])      return @"iPad Mini 2G (Cellular)";
    if ([platform isEqualToString:@"iPad4,6"])      return @"iPad Mini 2G";

    if ([platform isEqualToString:@"i386"])         return @"Simulator";
    if ([platform isEqualToString:@"x86_64"])       return @"Simulator";
    return platform;
}
@end

共實作兩個方法,使用方式就引用進來囉~

/**
 Theme: Device Information
 IDE: Xcode 6
 Language: Objective C
 Date: 103/11/14
 Author: HappyMan
 Blog: https://cg2010studio.wordpress.com/
 */
    // ---------------------------------------------------------------------- //
    // 獲取 Device Info, ex: 8.0.2 iPhone 6
    // ---------------------------------------------------------------------- //
    UIDeviceHardware *deviceHardware = [[UIDeviceHardware alloc] init];
    UIDevice *device = [UIDevice currentDevice];
    NSString *deviceInfo = [NSString stringWithFormat:@"%@ %@", [device systemVersion], [deviceHardware platformString]];

編譯執行後,用debug平台看變數值:

(lldb) po [deviceHardware platform]
iPhone7,2

(lldb) po [deviceHardware platformString]
iPhone 6

(lldb) po deviceInfo
8.0.2 iPhone 6
