應用統計中有時候需要上傳裝置型號，如果這樣寫：

[[UIDevice currentDevice] model]

獲得的裝置型號不是具體型號，如在iPhone5S上面執行，實測得到字串為@”iPhone”,我想要的是具體型號。
這裡提供一個方法來獲得裝置具體型號（版本與機型的對應關係來源於維基百科）：

- (NSString *)platform{
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString
 
 *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
    //未考慮iPhone3等較老裝置，未考慮iPad裝置（公司的應用不支援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;
}
