#import

一、通知

//监听App离开了__block RACDisposable*notf=[[[[NSNotificationCenter defaultCenter]rac_addObserverForName:UIApplicationWillResignActiveNotification object:nil]takeUntil:[selfrac_willDeallocSignal]]subscribeNext:^(NSNotification*_Nullable x){//分享结果回调,点击就算分享成功if(completion){completion(@"1",@"");//分享成功}[notf dispose];//销毁通知}];

二、监听对象属性变化（KVO）

[[_progressView rac_valuesForKeyPath:@"progress"observer:self]subscribeNext:^(id  _Nullable x){weakself.walkProgressView.progressView.progress=[x floatValue];}];

三、Button点击事件

[[cancelButton rac_signalForControlEvents:UIControlEventTouchUpInside] subscribeNext:^(__kindof UIControl * _Nullable x){}];
