1.RACSignal:信号类
创建信号：冷信号
RACSingal *signal = [RACSignal createSignal:^()]
订阅信号:热信号 RACSubcriber-发送信号
取消订阅 RACDispose

2，RACSubject:可创建信号，也可发送信号

 

 

RAC 宏

   // RAC:把一个对象的某个属性绑定一个信号,只要发出信号,就会把信号的内容给对象的属性赋值
    // 给label的text属性绑定了文本框改变的信号
    RAC(self.label, text) = self.textField.rac_textSignal;
//    [self.textField.rac_textSignal subscribeNext:^(id x) {
//        self.label.text = x;
//    }];
