iOS get device model, device type, and other information

Device identification

With regard to equipment identification, there have been many heroes in history, such as Udid, MAC address, Openudid, and so on, but they all continued to fall under the apple door. Apple currently offers 2 ways for apps to get the device ID: IDFA and IDFV

IDFA: Full name advertisingIdentifier , official explanation is advertising logo, applicable to advertising promotion, this advice is not easy to use, if used, the app must provide advertising function, otherwise it is likely to be rejected in AppStore audit. And IDFA can be closed by the user (set-"privacy"), once it is closed, it is not available.

IDFV: The full name Identifierforvendor, in the literal sense, the same vendor should have the same identifier. Vendor is defined by the first two of the app's Bundleid, such as the 2 Bundleid apps for Com.abc.app1 and Com.abc.app2, and they belong to the same vendor. IDFV is sure to get it. One thing to note is that when the user unloads all the apps under a vendor, the IDFV is reset, and when it's installed again, the IDFV gets to be different. So the plan I'm using is: Idfv+keychain. Of course, if the user chooses to restore the factory settings, then there will be a different, this situation can not be processed.

+ (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;}

Phone aliases

+ (NSString *) phonename{    return [[Uidevice Currentdevice] name];}

Mobile phone system version

/** *  Mobile System version * *  @return e.g. 8.0 */+ (NSString *) phoneversion{    return [[Uidevice Currentdevice] Systemversion];}

Phone model

This method only obtains the iphone, the ipad this kind of information, cannot obtain to is the iphone 4, iPhpone5 this specific model.

/** *  Phone model * *  @return e.g. IPhone */+ (NSString *) phonemodel{    return [[Uidevice Currentdevice] model];}

Device version

This code can be obtained to the specific device version (has been updated to the iphone 6s, iphone 6s Plus), the disadvantage is: the use of hard-coded. The specific correspondence can be consulted: https://www.theiphonewiki.com/wiki/Models

This method can pass AppStore audit, rest assured use it.
