安装输入源到Run Loop－－－分两步首先初始化一个输入源(init)，然后将这个输入源添加到当前Run Loop里面(addToCurrentRunLoop)
CFRunLoopSourceContext context = {0, (__bridge void *)(self), NULL, NULL, NULL, NULL, NULL,
&RunLoopSourceScheduleRoutine,
RunLoopSourceCancelRoutine,
RunLoopSourcePerformRoutine};
runLoopSource = CFRunLoopSourceCreate(NULL, 0, &context);
commands = [[NSMutableArray alloc] init];
CFRunLoopRef runLoop = CFRunLoopGetCurrent();
CFRunLoopAddSource(runLoop, runLoopSource, kCFRunLoopDefaultMode);
- (void)sourceFired
{
NSLog(@"Source fired: do some work, dude!");
NSThread *thread = [NSThread currentThread];
[thread cancel];
}
