RXSwift使用

按钮

    btn = UIButton()
    btn.rx.controlEvent(.touchUpInside).subscribe { (btn) in
        print("按钮点击")
    }.disposed(by: bag)
    btn.backgroundColor = .red
    view.addSubview(btn)
    btn.snp.makeConstraints { (make) in
        make.top.left.equalTo(50)
        make.height.equalTo(100)
        make.right.equalTo(-50)
    }

控件手势的使用

    lab = UILabel()
    view.addSubview(lab)
    lab.textColor = .white
    lab.backgroundColor = .blue
    lab.snp.makeConstraints { (make) in
        make.top.equalTo(btn.snp.bottom).offset(10)
        make.left.equalTo(10)
        make.height.equalTo(30)
        make.right.equalTo(-10)
    }
    let tap = UITapGestureRecognizer()
    lab.isUserInteractionEnabled = true
    lab.addGestureRecognizer(tap)
    lab.tag = 99
    tap.rx.event.bind { (tap) in
        print(tap.location(in: self.view),tap.view?.tag)
    }.disposed(by: bag)
