ios--Creation of Threads

1. Get the current thread

2.  Another way to get the main thread

3. Create a new thread
(1) Create directly

     Nsthread  Object:@ " thread A"];      // set a name     for a thread Thread.name=@ " thread A";       // Open Thread     [Thread start];

(2) Thread auto start after creation

//     nsthread *thread=[nsthread detachnewthreadselector: @selector (run:) totarget:self withobject:@ "created thread Direct (automatic) Start "];     [Nsthread detachnewthreadselector: @selector (run:) totarget:self withobject:@ " create thread Direct (auto) start " ];

(3) Implicit creation

      // execute in a background thread = = = in a child thread     [Self Performselectorinbackground: @selector (run:) Withobject:@ " implicitly created "];
