IOS代码判断设备类型

判断IOS设备类型一般会使用

[objc]  view plain copy 在CODE上查看代码片 派生到我的代码片
  1. //设备名称
  2. return [UIDevice currentDevice].name;
  4. //设备型号，只可得到是何设备，无法得到是第几代设备
  5. return [UIDevice currentDevice].model;
  7. //系统版本型号,如iPhone OS 
  8. return [UIDevice currentDevice].systemVersion;
  10. //系统版本名称，如6.1.3
  11. return [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

[objc]  view plain copy 在CODE上查看代码片 派生到我的代码片
  1. #import <sys/utsname.h>
  3. NSString*
  4. machineName()
  5. {
  6.     struct utsname systemInfo;
  7.     uname(&systemInfo);
  9.     return [NSString stringWithCString:systemInfo.machine
  10.                               encoding:NSUTF8StringEncoding];
  11. }

结果可能为如下的以逗号分隔的字符串

  1. @”i386″      on the simulator
  2. @”iPod1,1″   on iPod Touch
  3. @”iPod2,1″   on iPod Touch Second Generation
  4. @”iPod3,1″   on iPod Touch Third Generation
  5. @”iPod4,1″   on iPod Touch Fourth Generation
  6. @”iPhone1,1″ on iPhone
  7. @”iPhone1,2″ on iPhone 3G
  8. @”iPhone2,1″ on iPhone 3GS
  9. @”iPad1,1″   on iPad
  10. @”iPad2,1″   on iPad 2
  11. @”iPad3,1″   on 3rd Generation iPad
  12. @”iPhone3,1″ on iPhone 4
  13. @”iPhone4,1″ on iPhone 4S
  14. @”iPhone5,1″ on iPhone 5 (model A1428, AT&T/Canada)
  15. @”iPhone5,2″ on iPhone 5 (model A1429, everything else)
  16. @”iPad3,4″ on 4th Generation iPad
  17. @”iPad2,5″ on iPad Mini
  18. @”iPhone5,3″ on iPhone 5c (model A1456, A1532 | GSM)
  19. @”iPhone5,4″ on iPhone 5c (model A1507, A1516, A1526 (China), A1529 | Global)
  20. @”iPhone6,1″ on iPhone 5s (model A1433, A1533 | GSM)
  21. @”iPhone6,2″ on iPhone 5s (model A1457, A1518, A1528 (China), A1530 | Global)
  22. @”iPad4,1″ on 5th Generation iPad (iPad Air) – Wifi
  23. @”iPad4,2″ on 5th Generation iPad (iPad Air) – Cellular
  24. @”iPad4,4″ on 2nd Generation iPad Mini – Wifi
  25. @”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

[objc]  view plain copy 在CODE上查看代码片 派生到我的代码片
  1. #import <sys/utsname.h>
  3. NSString *machineName()
  4. {
  5.     struct utsname systemInfo;
  6.     uname(&systemInfo);
  8.     NSString *iOSDeviceModelsPath = [[NSBundle mainBundle] pathForResource:@”iOSDeviceModelMapping” ofType:@”plist”];
  9.     NSDictionary *iOSDevices = [NSDictionary dictionaryWithContentsOfFile:iOSDeviceModelsPath];
  11.     NSString* deviceModel = [NSString stringWithCString:systemInfo.machine
  12.                                                encoding:NSUTF8StringEncoding];
  14.     return [iOSDevices valueForKey:deviceModel];
  15. }

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

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

  1. #import <sys/utsname.h>
  3. – (NSString*) deviceName
  4. {
  5.     struct utsname systemInfo;
  7.     uname(&systemInfo);
  9.     NSString* code = [NSString stringWithCString:systemInfo.machine
  10.                                         encoding:NSUTF8StringEncoding];
  12.     static NSDictionary* deviceNamesByCode = nil;
  14.     if (!deviceNamesByCode) {
  16.         deviceNamesByCode = @{@”i386″      :@”Simulator”,
  17.                               @”iPod1,1″   :@”iPod Touch”,      // (Original)
  18.                               @”iPod2,1″   :@”iPod Touch”,      // (Second Generation)

  40.                               @”iPad4,5″   :@”iPad Mini”        // (2nd Generation iPad Mini – Cellular)
  41.                               };
  42.     }
  44.     NSString* deviceName = [deviceNamesByCode objectForKey:code];
  46.     if (!deviceName) {
  47.         // Not found on database. At least guess main device type from string contents:
  49.         if ([deviceName rangeOfString:@”iPod”].location != NSNotFound) {
  50.             deviceName = @”iPod Touch”;
  51.         }
  52.         else if([deviceName rangeOfString:@”iPad”].location != NSNotFound) {
  53.             deviceName = @”iPad”;
  54.         }
  55.         else if([deviceName rangeOfString:@”iPhone”].location != NSNotFound){
  56.             deviceName = @”iPhone”;

  58.     }
  60.     return deviceName;
  61. }
  63. // (rest of class implementation omitted)
  65. @end

 

后面加个获取系统版本号的，好记心不如烂笔头

[objc]  view plain copy
  1. NSLog(@”System Name: %@”, [[UIDevice currentDevice] systemName]);  //”iPhone OS”
  2. NSLog(@”System Version: %@”, [[UIDevice currentDevice] systemVersion]);  //7.0.3
