counter: Retaincount. Method:-(NSUInteger) retainCount;//格式化方法：％ld The DEALLOC message is automatically sent to the object when the reserved counter of the object is returned to 0 o'clock. You can override the Dealloc method in your own object, which frees all related resources that have already been allocated, and you cannot call the Dealloc method directly. 9.12 Object Ownership When an entity owns an object, the entity is res

By defining a clear, cross-platform memory model that has been modified in JDK 5.0 to correct some of the errors in the original definition, it is possible to build a concurrency class "write once, run Anywhere", by following this simple rule: Whenever you write a variable that might be read by another thread, or if the variable you are reading is finally written by another thread,

this simple rule: Whenever you write a variable that might be read by another thread, or if the variable you are reading is finally written by another thread, you must synchronize. But now a little better, in the nearest JVM, there is no contention for synchronization (when a thread owns a lock, no other thread attempts to acquire the lock) the performance cost is still low. (This is not always the case; synchronization in the early J
