"OBJECTIVE-C Programming" must explicitly describe intended ownership of an object array parameter exception error solution

At the time of making a multi-graphic example of an OOP of OC. Xcode unprovoked report must explicitly describe intended ownership of an object array parameter"Exception information, check the code a few times or the compiler error, After looking for a long time to know the reason, now share this error to everyone.

Key code for error:

• Wrong translation: the ownership of the target object must be explicitly described. Personal understanding is probably the problem of allocating space, not conforming to the rules of memory management

• 
  

  treatment: The solution is to set the project Automatic Reference counting to No, because you Xcode4.2 the above with this setting and the default setting is yes. This setting is primarily to set up automatic memory management. We set it to not automatically manage the error .

  Ok. On this mistake to share this, there is not the right place to point out to explore and learn from each other!
