UIAlertView *aaa = [[UIAlertView alloc] initWithTitle:@"提示" message:@"dadsads" delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[aaa.rac_buttonClickedSignal subscribeNext:^(id x) {
NSLog(@"%@",x);
}];
[aaa show];
关于recativecocoa 为什么可以实现点击识别功能
api里面也就是这两个方法
rac_buttonClickedSignal相当与一个category内部拷贝回调实现
- (RACDisposable *)subscribeNext:(void (^)(id x))nextBlock
subscriber->_next = [next copy]
