IOS代码判断设备类型

来源：互联网发布：一贯道知乎编辑：程序博客网时间：2024/05/17 02:33

判断IOS设备类型一般会使用

//设备名称return [UIDevice currentDevice].name;//设备型号，只可得到是何设备，无法得到是第几代设备return [UIDevice currentDevice].model;//系统版本型号,如iPhone OS return [UIDevice currentDevice].systemVersion;//系统版本名称，如6.1.3return [UIDevice currentDevice].systemName;

但是，这样只能区分iPhone，iPad

真正能够实现设备类型区分的方法如下

#import <sys/utsname.h>NSString*machineName(){    struct utsname systemInfo;    uname(&systemInfo);    return [NSString stringWithCString:systemInfo.machine                              encoding:NSUTF8StringEncoding];}

结果可能为如下的以逗号分隔的字符串

@"i386"      on the simulator@"iPod1,1"   on iPod Touch@"iPod2,1"   on iPod Touch Second Generation@"iPod3,1"   on iPod Touch Third Generation@"iPod4,1"   on iPod Touch Fourth Generation@"iPhone1,1" on iPhone@"iPhone1,2" on iPhone 3G@"iPhone2,1" on iPhone 3GS@"iPad1,1"   on iPad@"iPad2,1"   on iPad 2@"iPad3,1"   on 3rd Generation iPad@"iPhone3,1" on iPhone 4@"iPhone4,1" on iPhone 4S@"iPhone5,1" on iPhone 5 (model A1428, AT&T/Canada)@"iPhone5,2" on iPhone 5 (model A1429, everything else)@"iPad3,4" on 4th Generation iPad@"iPad2,5" on iPad Mini@"iPhone5,3" on iPhone 5c (model A1456, A1532 | GSM)@"iPhone5,4" on iPhone 5c (model A1507, A1516, A1526 (China), A1529 | Global)@"iPhone6,1" on iPhone 5s (model A1433, A1533 | GSM)@"iPhone6,2" on iPhone 5s (model A1457, A1518, A1528 (China), A1530 | Global)@"iPad4,1" on 5th Generation iPad (iPad Air) - Wifi@"iPad4,2" on 5th Generation iPad (iPad Air) - Cellular@"iPad4,4" on 2nd Generation iPad Mini - Wifi@"iPad4,5" on 2nd Generation iPad Mini - Cellular

为了简化代码，网上找到了如下实现，是通过NSDictionary实现快速查询

#import <sys/utsname.h>NSString *machineName(){    struct utsname systemInfo;    uname(&systemInfo);    NSString *iOSDeviceModelsPath = [[NSBundle mainBundle] pathForResource:@"iOSDeviceModelMapping" ofType:@"plist"];    NSDictionary *iOSDevices = [NSDictionary dictionaryWithContentsOfFile:iOSDeviceModelsPath];    NSString* deviceModel = [NSString stringWithCString:systemInfo.machine                                               encoding:NSUTF8StringEncoding];    return [iOSDevices valueForKey:deviceModel];}

在xCode解决方案中添加以iOSDeviceModelMapping.plist命名的plist文件，内容如下

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict><key>x86_64</key><string>Simulator</string><key>i386</key><string>Simulator</string><key>iPod1,1</key><string>iPod Touch 1st Gen</string><key>iPod2,1</key><string>iPod Touch 2nd Gen</string><key>iPod3,1</key><string>iPod Touch 3rd Gen</string><key>iPod4,1</key><string>iPod Touch 4th Gen</string><key>iPod5,1</key><string>iPod Touch 5th Gen</string><key>iPhone1,1</key><string>iPhone</string><key>iPhone1,2</key><string>iPhone 3G</string><key>iPhone2,1</key><string>iPhone 3GS</string><key>iPhone3,1</key><string>iPhone 4</string><key>iPhone3,2</key><string>iPhone 4</string><key>iPhone3,3</key><string>iPhone 4</string><key>iPhone4,1</key><string>iPhone 4S</string><key>iPhone5,1</key><string>iPhone 5 model A1428</string><key>iPhone5,2</key><string>iPhone 5 model A1429</string><key>iPhone5,3</key><string>iPhone 5C</string><key>iPhone5,4</key><string>iPhone 5C</string><key>iPhone6,1</key><string>iPhone 5S</string><key>iPhone6,2</key><string>iPhone 5S</string><key>iPad1,1</key><string>iPad</string><key>iPad2,1</key><string>iPad 2</string><key>iPad2,2</key><string>iPad 2</string><key>iPad2,3</key><string>iPad 2</string><key>iPad2,4</key><string>iPad 2</string><key>iPad3,1</key><string>iPad 3rd Gen</string><key>iPad3,2</key><string>iPad 3rd Gen</string><key>iPad3,3</key><string>iPad 3rd Gen</string><key>iPad3,4</key><string>iPad 4th Gen</string><key>iPad3,5</key><string>iPad 4th Gen</string><key>iPad3,6</key><string>iPad 4th Gen</string><key>iPad4,1</key><string>iPad Air</string><key>iPad4,2</key><string>iPad Air</string><key>iPad2,5</key><string>iPad Mini 1st Gen</string><key>iPad2,6</key><string>iPad Mini 1st Gen</string><key>iPad2,7</key><string>iPad Mini 1st Gen</string><key>iPad4,4</key><string>iPad Mini 2nd Gen</string><key>iPad4,5</key><string>iPad Mini 2nd Gen</string></dict></plist>

当MachineName方法时，NSDictionary通过匹配key，即utsname.machine的值，判断设备类型。

网上找到的类似的解决方法

#import <sys/utsname.h>- (NSString*) deviceName{    struct utsname systemInfo;    uname(&systemInfo);    NSString* code = [NSString stringWithCString:systemInfo.machine                                        encoding:NSUTF8StringEncoding];    static NSDictionary* deviceNamesByCode = nil;    if (!deviceNamesByCode) {        deviceNamesByCode = @{@"i386"      :@"Simulator",                              @"iPod1,1"   :@"iPod Touch",      // (Original)                              @"iPod2,1"   :@"iPod Touch",      // (Second Generation)                              @"iPod3,1"   :@"iPod Touch",      // (Third Generation)                              @"iPod4,1"   :@"iPod Touch",      // (Fourth Generation)                              @"iPhone1,1" :@"iPhone",          // (Original)                              @"iPhone1,2" :@"iPhone",          // (3G)                              @"iPhone2,1" :@"iPhone",          // (3GS)                              @"iPad1,1"   :@"iPad",            // (Original)                              @"iPad2,1"   :@"iPad 2",          //                              @"iPad3,1"   :@"iPad",            // (3rd Generation)                              @"iPhone3,1" :@"iPhone 4",        //                              @"iPhone4,1" :@"iPhone 4S",       //                              @"iPhone5,1" :@"iPhone 5",        // (model A1428, AT&T/Canada)                              @"iPhone5,2" :@"iPhone 5",        // (model A1429, everything else)                              @"iPad3,4"   :@"iPad",            // (4th Generation)                              @"iPad2,5"   :@"iPad Mini",       // (Original)                              @"iPhone5,3" :@"iPhone 5c",       // (model A1456, A1532 | GSM)                              @"iPhone5,4" :@"iPhone 5c",       // (model A1507, A1516, A1526 (China), A1529 | Global)                              @"iPhone6,1" :@"iPhone 5s",       // (model A1433, A1533 | GSM)                              @"iPhone6,2" :@"iPhone 5s",       // (model A1457, A1518, A1528 (China), A1530 | Global)                              @"iPad4,1"   :@"iPad Air",        // 5th Generation iPad (iPad Air) - Wifi                              @"iPad4,2"   :@"iPad Air",        // 5th Generation iPad (iPad Air) - Cellular                              @"iPad4,4"   :@"iPad Mini",       // (2nd Generation iPad Mini - Wifi)                              @"iPad4,5"   :@"iPad Mini"        // (2nd Generation iPad Mini - Cellular)                              };    }    NSString* deviceName = [deviceNamesByCode objectForKey:code];    if (!deviceName) {        // Not found on database. At least guess main device type from string contents:        if ([deviceName rangeOfString:@"iPod"].location != NSNotFound) {            deviceName = @"iPod Touch";        }        else if([deviceName rangeOfString:@"iPad"].location != NSNotFound) {            deviceName = @"iPad";        }        else if([deviceName rangeOfString:@"iPhone"].location != NSNotFound){            deviceName = @"iPhone";        }    }    return deviceName;}// (rest of class implementation omitted)@end

后面加个获取系统版本号的，好记心不如烂笔头

    NSLog(@"System Name: %@", [[UIDevice currentDevice] systemName]);  //"iPhone OS"    NSLog(@"System Version: %@", [[UIDevice currentDevice] systemVersion]);  //7.0.3
