ReactiveCocoa实践

1.按钮addTarget

[[self.aDepositBtn rac_signalForControlEvents:UIControlEventTouchUpInside] subscribeNext:^(__kindof UIControl * _Nullable x) {         //点击处理     }];

2.View加tap事件

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] init];     @weakify(self);     [[tap rac_gestureSignal] subscribeNext:^(id x) {         @strongify(self);     }];     [infoView addGestureRecognizer:tap];

3.KVO监听对象的某个属性

[RACObserve(self.mobileTextField, text) subscribeNext:^(id  _Nullable x) {         NSString * text = (NSString *)x;         if (text.length) {             //将提交按钮置为蓝色                      } else {             //将提交按钮置为灰色         }     }];

 

4.通知传值

[[NSNotificationCenter defaultCenter] postNotificationName:@"RACNotification" object:@[@"1",@"2"]];

 

[[[NSNotificationCenter defaultCenter]rac_addObserverForName:@"RACNotification" object:nil]subscribeNext:^(id x) {         NSLog(@"%@",x);     }];

5.UITextField输入结束等类似的代理方法

 

[[self.textField rac_signalForControlEvents:UIControlEventEditingDidEnd] subscribeNext:^(id x){         //x是textField对象         NSLog(@"%@",x);     }];
