iOS：#include &sys/types.h&#include &sys/sysctl.h&- (NSString *)deviceName {
//iOS device by sheepkx
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *name = malloc(size);
sysctlbyname("hw.machine", name, &size, NULL, 0);
NSString *platform= [NSString stringWithUTF8String:name];
if ([platform isEqualToString:@"iPhone2,1"])
return @"iPhone3GS";
if ([platform isEqualToString:@"iPhone3,1"]||[platform isEqualToString:@"iPhone3,2"]||[platform isEqualToString:@"iPhone3,3"])
return @"iPhone4";
if ([platform isEqualToString:@"iPhone4,1"])
return @"iPhone4s";
if ([platform isEqualToString:@"iPhone5,1"]||[platform isEqualToString:@"iPhone5,2"])
return @"iPhone5";
if ([platform isEqualToString:@"iPhone6,1"]||[platform isEqualToString:@"iPhone6,2"]||[platform isEqualToString:@"iPhone6,3"])
return @"iPhone5s";
if ([platform isEqualToString:@"iPod3,1"])
return @"iPod 3G";
if ([platform isEqualToString:@"iPod4,1"])
return @"iPod 4G";
if ([platform isEqualToString:@"iPad1,1"])
return @"iPad";
if ([platform isEqualToString:@"iPad2,1"]||[platform isEqualToString:@"iPad2,2"]||[platform isEqualToString:@"iPad2,3"])
return @"iPad2";
if ([platform isEqualToString:@"iPad2,5"]||[platform isEqualToString:@"iPad2,6"])
return @"iPad mini";
if ([platform isEqualToString:@"i386"])
return @"Simulator";
if ([platform isEqualToString:@"x86_64"])
return @"Simulator";
}iPhone 5s,iOS7测试通过。这里只是新型号，全部型号可以去找到。Android:String deviceName = android.os.Build.MODEL;System.out.println(deviceName);米2测试通过。
