iOS獲取設(shè)備型號(hào)、設(shè)備類型等信息

設(shè)備標(biāo)識(shí)
關(guān)于設(shè)備標(biāo)識(shí)，歷史上盛行過(guò)很多英雄，比如UDID、Mac地址、OpenUDID等，然而他們都陸陸續(xù)續(xù)倒在了蘋(píng)果的門下。蘋(píng)果目前提供了2個(gè)方法供App獲取設(shè)備標(biāo)識(shí)：idfa和idfv

idfa：全稱advertisingIdentifier，官方解釋是廣告標(biāo)識(shí)，適用于廣告推廣，這個(gè)建議不要輕易使用，如果用了，則App里必須提供廣告功能，否則很有可能會(huì)在AppStore審核時(shí)被拒。而且idfa是可以被用戶關(guān)閉的（設(shè)置-》隱私），一旦被關(guān)閉，就獲取不到了。

idfv：全稱identifierForVendor，按照字面意思理解，相同的Vendor應(yīng)該有相同的identifier。Vendor是根據(jù)app的bundleid的前兩位來(lái)界定的，比如對(duì)于com.abc.app1和com.abc.app2這2個(gè)bundleid的app來(lái)說(shuō)，他們就屬于同一個(gè)vendor。idfv是一定可以獲取到的。需要注意的一點(diǎn)是，當(dāng)用戶將某個(gè)vendor下的所有app都卸載掉時(shí)，idfv就會(huì)被重置，再次安裝時(shí)，獲取到的idfv會(huì)跟之前的不一樣。所以我用的方案是：idfv+keychain。當(dāng)然如果用戶選擇恢復(fù)出廠設(shè)置，那么還是會(huì)出現(xiàn)不一樣，這種情況就沒(méi)法處理了。

+(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;
}

手機(jī)別名

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

手機(jī)系統(tǒng)版本
/**

• 手機(jī)系統(tǒng)版本
• @return e.g. 8.0
  */

+(NSString *)phoneVersion{
    return [[UIDevice currentDevice] systemVersion];
}

手機(jī)型號(hào)
這個(gè)方法只能獲取到iPhone、iPad這種信息，無(wú)法獲取到是iPhone 4、iPhpone5這種具體的型號(hào)。
/**

• 手機(jī)型號(hào)
• @return e.g. iPhone
  */

+(NSString *)phoneModel{
    return [[UIDevice currentDevice] model];
}

設(shè)備版本
這個(gè)代碼可以獲取到具體的設(shè)備版本（已更新到iPhone 6s、iPhone 6s Plus），缺點(diǎn)是：采用的硬編碼。具體的對(duì)應(yīng)關(guān)系可以參考：https://www.theiphonewiki.com/wiki/Models
這個(gè)方法可以通過(guò)AppStore的審核，放心用吧。
