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
 */
