React-Native防止重复点击

constructor(props) {
    this.buttonEnable = true;//控制按钮不能同一时间多次点击
}

 //控制0.5秒内不可多次点击
        if(!this.buttonEnable){
            return;
        }
        this.buttonEnable = false;

function a(){
}


      this.setTimer = setTimeout(()=>{
            this.buttonEnable = true;
        }, 300);

componentWillUnmount(){

        this.setTimer && clearTimeout(this.setTimer);

    };
