IDFA - 3

前面两篇对IDFA简单地介绍了一下，这里根据这个文章（非常好）总结一下每处在代码中的简单实用方法：

1.UDID

iOS5以上代码被苹果禁掉了，相信很多人都会查看：



2.UUID

- (NSString *)getUID
{

return [[[NSUUID alloc] init] UUIDString];
}

3.MAC Adress

NSString * macaddr = [MacAddress GetMacAddress];

去Github找个算法

4.IDFA

+ (NSString *)getAdvertisingIdentify
{
NSString *idfa = @"";
if (VERSION_FLOAT >= 6.0)
{
ASIdentifierManager *idManager = [ASIdentifierManager sharedManager];
if ([idManager isAdvertisingTrackingEnabled])
{
idfa = [NSString stringWithFormat:@"%@",[[idManager advertisingIdentifier] UUIDString]];
}
}
return idfa;
}

5.IDFV

+ (NSString *)getIDFVString
{
NSString *idfv = @"";
if (VERSION_FLOAT >= 6.0)
{
idfv = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
}
return idfv;
}

6.openUDID
