What is RAC?

In fact, RAC is a simplified code of the third-party library Reactivecocoa, directly with Cocoapods added to the project can be, podfile file add pod ' Reactivecocoa ', and then terminal pod Install, header file reference:

#import <ReactiveCocoa/ReactiveCocoa.h>

Using RAC

1. Methods

The simplest use of RAC is to listen to events.

If you now have a button, if you want to add a click event method to the button, we will typically do this:

/// Add a Click event [Self.button addtarget:self Action: @selector (ButtonClick:) forcontrolevents:uicontroleventtouchupinside]; /// method Implementation -(void) ButtonClick: (UIButton *) sender{    NSLog (@ " click button " );}

But if you use RAC, you can do this:

[[Self.button Rac_signalforcontrolevents:uicontroleventtouchupinside] subscribenext:^ (ID  x) {     NSLog (@ " click button");    }];
