The MAC address is obtained because uuid cannot be obtained after IOS5. The code below is highly reusable and can be used as an important reference. # Pragma mark MAC // Return the local MAC addy // Courtesy of FreeBSD hackers email list // Accidentally munged during previous update.

First of all, the following two methods can get the phone's MAC address, but there is a limit, in the iOS7 below can be obtained. IOS7 after the Apple for SYSCTL and IOCTL technical processing, MAC address returned are 02:00:00:00:00:00. It is written in the official document: "Twolow-level networking APIs that used to return a MAC address now return thefixed value 02:00:00:00:00:00." The APIs in question are Sysctl (net_rt_iflist) and IOCTL (siocgifconf). Developers using the value of the MAC

The use of SNMP has become a default project for many devices. Then, some of the module applications have become the focus of attention. This article mainly introduces the establishment of SNMP Trap. First, let's take a look at the use environment of this Protocol. Develop Trap macro types It should be noted that the expansion of the Trap macro occurs in terms of completion, not during running. Formulate enterprise terms Enterprise terms must be existing, define enterprise management, and regist

Hibernate knowledge point sorting1. Requirements for persistence objects 1) provide a non-argument constructor 2) provide an identity attribute, such as id, which is usually mapped to the primary key field of the database table. 3) provides get and set methods for fields in the persistence class. Note: not all fields do this. For fields that do not provide the get or set method, they must be processed in the ing file (*. hbm. xml. For example, if the get and set methods are not set for a propert

1. Persist the state of the object:Standing in the perspective of persistence, Hibernate divides objects into four states: persistent state, temporary state, Free State, delete stateSpecific methods of the Session can move an object from one state to anotherTemporary objects:OID is usually null in the case of using a proxy primary keyNot in the Session's cacheThere are no corresponding records in the databasePersisted objects (also called managed):OID
