problems are: affecting system functions or operations. The main functions have defects, but do not affect system stability.The details can be basically divided:○ Function not implemented○ Function Error○ System refresh Error○ Incorrect voice or Data Communication○ Slight numeric calculation error○ The functions or services provided by the system are obviously affected.

If an object is called without a declared method, the compilation can pass; the link can pass; but it cannot run;
If you declare a method that is not implemented, compile and link all can pass;
OC in the call method is in the process of running the object will not be detected to implement the corresponding method;
If you implement a method, no definition, compile and link can pass, run can also be successful;
