First, be familiar with the arc mechanism: first of all, to understand the arc of the past life, if not clear will lead to two possible, 1, an object's reference inexplicable is empty, or invalid. This can generally be found in the development phase, because it can lead to application exceptions. 2, causing memory overflow; it is very easy to understand that the arc mechanism can easily cause memory to not be released properly. If the memory test is not intentionally done, then it will be expose
