Question

我试图在Firebase Analytics中创建一个受众群体，以按主要iOS版本对用户进行分组。

因此，我创建了一个按流过滤的新受众群体，因为项目包含的不仅仅是生产iOS应用程序，然后我设置了另一个条件以按 User Property-> OS version 进行过滤。对于iOS 11.x，我将其设置为包含ios 11。或尝试使用正则表达式 ios 11。* 。没有一个有效，我总是得到0个用户，即使在未经过滤的仪表板上也有这样的用户。

没有人知道什么是正确的条件吗？谢谢

由于iOS版本（major.minor.patch）中有两个小数点，因此该属性是字符串而不是数字。最简单的方法是在Firebase Web控制台中创建一个名为“ iOSMajorVersion”的用户属性。转到分析：用户属性以执行此操作。然后在您的代码中，获取主要版本并向Firebase报告。这有助于确保每个用户会话仅执行一次此操作。在Objective-C中，您可以通过块或异步GDC调度来实现。

您没有提到要使用Objective-C还是Swift，但这是您可以使用的方法。

Objective-C

@Query(value = "select u from users u join users_role ur on u.id = ur.user_id join roles r on ur.role_id = r.id where r.role = 'ROLE_PL' ")
List<User> findPersonels();
