應用統計中有時候需要上傳設備型號，如果這樣寫：

[[UIDevice currentDevice] model]

獲得的設備型號不是具體型號，如在iPhone5S上面運行，實測得到字符串為@”iPhone”,我想要的是具體型號。
這裡提供一個方法來獲得設備具體型號（版本與機型的對應關系來源於維基百科）：

- (NSString *)platform{
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
    //未考慮iPhone3等較老設備，未考慮iPad設備（公司的應用不支持iPad）
    if ([deviceString hasPrefix:@iPhone3])    return @iPhone 4;
    if ([deviceString isEqualToString:@iPhone4,1])    return @iPhone 4S;
    if ([deviceString isEqualToString:@iPhone5,1]||[deviceString isEqualToString:@iPhone5,2])    return @iPhone 5;
    if ([deviceString isEqualToString:@iPhone5,3]||[deviceString isEqualToString:@iPhone5,4])    return @iPhone 5C;
    if ([deviceString hasPrefix:@iPhone6])    return @iPhone 5S;
    if ([deviceString isEqualToString:@iPhone7,1])    return @iPhone 6 Plus;
    if ([deviceString isEqualToString:@iPhone7,2])    return @iPhone 6;
    if ([deviceString isEqualToString:@i386])         return @Simulator;
    if ([deviceString isEqualToString:@x86_64])       return @Simulator;
    //如果沒有匹配直接返回系統提供的類似@iPhone5,3這種型號
    return deviceString;
}
