[操作系统]iOS获取设备型号、设备类型等信息


设备标识

关于设备标识,历史上盛行过很多英雄,比如UDID、Mac地址、OpenUDID等,然而他们都陆陆续续倒在了苹果的门下。苹果目前提供了2个方法供App获取设备标识:idfa和idfv

idfa:全称advertisingIdentifier,官方解释是广告标识,适用于广告推广,这个建议不要轻易使用,如果用了,则App里必须提供广告功能,否则很有可能会在AppStore审核时被拒。而且idfa是可以被用户关闭的(设置-》隐私),一旦被关闭,就获取不到了。

idfv:全称identifierForVendor,按照字面意思理解,相同的Vendor应该有相同的identifier。Vendor是根据app的bundleid的前两位来界定的,比如对于com.abc.app1和com.abc.app2这2个bundleid的app来说,他们就属于同一个vendor。idfv是一定可以获取到的。需要注意的一点是,当用户将某个vendor下的所有app都卸载掉时,idfv就会被重置,再次安装时,获取到的idfv会跟之前的不一样。所以我用的方案是:idfv+keychain。当然如果用户选择恢复出厂设置,那么还是会出现不一样,这种情况就没法处理了。

+(NSString *)identifier{  NSString *key = @"com.app.keychain.uuid";  KeychainItemWrapper *keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:key accessGroup:nil];    NSString *strUUID = [keychainItem objectForKey:(__bridge id)kSecValueData];    if (strUUID.length <= 0) {    strUUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString];        [keychainItem setObject:@"uuid" forKey:(__bridge id)kSecAttrAccount];    [keychainItem setObject:strUUID forKey:(__bridge id)kSecValueData];  }    return strUUID;}

手机别名

+(NSString *)phoneName{  return [[UIDevice currentDevice] name];}

手机系统版本

/** * 手机系统版本 * * @return e.g. 8.0 */+(NSString *)phoneVersion{  return [[UIDevice currentDevice] systemVersion];}

手机型号

这个方法只能获取到iPhone、iPad这种信息,无法获取到是iPhone 4、iPhpone5这种具体的型号。

/** * 手机型号 * * @return e.g. iPhone */+(NSString *)phoneModel{  return [[UIDevice currentDevice] model];}

设备版本

这个代码可以获取到具体的设备版本(已更新到iPhone 6s、iPhone 6s Plus),缺点是:采用的硬编码。具体的对应关系可以参考:https://www.theiphonewiki.com/wiki/Models

这个方法可以通过AppStore的审核,放心用吧。

/** * 设备版本 * * @return e.g. iPhone 5S */+ (NSString*)deviceVersion{  // 需要#import "sys/utsname.h"  struct utsname systemInfo;  uname(&systemInfo);  NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];    //iPhone  if ([deviceString isEqualToString:@"iPhone1,1"])  return @"iPhone 1G";  if ([deviceString isEqualToString:@"iPhone1,2"])  return @"iPhone 3G";  if ([deviceString isEqualToString:@"iPhone2,1"])  return @"iPhone 3GS";  if ([deviceString isEqualToString:@"iPhone3,1"])  return @"iPhone 4";  if ([deviceString isEqualToString:@"iPhone3,2"])  return @"Verizon iPhone 4";  if ([deviceString isEqualToString:@"iPhone4,1"])  return @"iPhone 4S";  if ([deviceString isEqualToString:@"iPhone5,1"])  return @"iPhone 5";  if ([deviceString isEqualToString:@"iPhone5,2"])  return @"iPhone 5";  if ([deviceString isEqualToString:@"iPhone5,3"])  return @"iPhone 5C";  if ([deviceString isEqualToString:@"iPhone5,4"])  return @"iPhone 5C";  if ([deviceString isEqualToString:@"iPhone6,1"])  return @"iPhone 5S";  if ([deviceString isEqualToString:@"iPhone6,2"])  return @"iPhone 5S";  if ([deviceString isEqualToString:@"iPhone7,1"])  return @"iPhone 6 Plus";  if ([deviceString isEqualToString:@"iPhone7,2"])  return @"iPhone 6";  if ([deviceString isEqualToString:@"iPhone8,1"])  return @"iPhone 6s";  if ([deviceString isEqualToString:@"iPhone8,2"])  return @"iPhone 6s Plus";    //iPod  if ([deviceString isEqualToString:@"iPod1,1"])   return @"iPod Touch 1G";  if ([deviceString isEqualToString:@"iPod2,1"])   return @"iPod Touch 2G";  if ([deviceString isEqualToString:@"iPod3,1"])   return @"iPod Touch 3G";  if ([deviceString isEqualToString:@"iPod4,1"])   return @"iPod Touch 4G";  if ([deviceString isEqualToString:@"iPod5,1"])   return @"iPod Touch 5G";    //iPad  if ([deviceString isEqualToString:@"iPad1,1"])   return @"iPad";  if ([deviceString isEqualToString:@"iPad2,1"])   return @"iPad 2 (WiFi)";  if ([deviceString isEqualToString:@"iPad2,2"])   return @"iPad 2 (GSM)";  if ([deviceString isEqualToString:@"iPad2,3"])   return @"iPad 2 (CDMA)";  if ([deviceString isEqualToString:@"iPad2,4"])   return @"iPad 2 (32nm)";  if ([deviceString isEqualToString:@"iPad2,5"])   return @"iPad mini (WiFi)";  if ([deviceString isEqualToString:@"iPad2,6"])   return @"iPad mini (GSM)";  if ([deviceString isEqualToString:@"iPad2,7"])   return @"iPad mini (CDMA)";    if ([deviceString isEqualToString:@"iPad3,1"])   return @"iPad 3(WiFi)";  if ([deviceString isEqualToString:@"iPad3,2"])   return @"iPad 3(CDMA)";  if ([deviceString isEqualToString:@"iPad3,3"])   return @"iPad 3(4G)";  if ([deviceString isEqualToString:@"iPad3,4"])   return @"iPad 4 (WiFi)";  if ([deviceString isEqualToString:@"iPad3,5"])   return @"iPad 4 (4G)";  if ([deviceString isEqualToString:@"iPad3,6"])   return @"iPad 4 (CDMA)";    if ([deviceString isEqualToString:@"iPad4,1"])   return @"iPad Air";  if ([deviceString isEqualToString:@"iPad4,2"])   return @"iPad Air";  if ([deviceString isEqualToString:@"iPad4,3"])   return @"iPad Air";  if ([deviceString isEqualToString:@"iPad5,3"])   return @"iPad Air 2";  if ([deviceString isEqualToString:@"iPad5,4"])   return @"iPad Air 2";  if ([deviceString isEqualToString:@"i386"])     return @"Simulator";  if ([deviceString isEqualToString:@"x86_64"])    return @"Simulator";    if ([deviceString isEqualToString:@"iPad4,4"]    ||[deviceString isEqualToString:@"iPad4,5"]    ||[deviceString isEqualToString:@"iPad4,6"])   return @"iPad mini 2";    if ([deviceString isEqualToString:@"iPad4,7"]    ||[deviceString isEqualToString:@"iPad4,8"]    ||[deviceString isEqualToString:@"iPad4,9"])   return @"iPad mini 3";    return deviceString;}
