    title:"",

    success:function(){

        console.log(“播放成功”)

    },

    fail:function(){

        console.log(“播放失败”)

    }

})

this.time()

然后还调用了一个计时，结果计时也没有启动…

time: function () {

//计时

    var that = this;

    var sec = this.data.sec;

    int = setInterval(function () {

        //逻辑

        sec++;

        // 设置秒

        if (sec > 0 && sec < 10) {

            that.setData({

                sec: “0” + sec

            })

        } else {

            that.setData({

                sec: sec

            })

        }

    }, 1000)

},

之前还能播放，但是这两天突然就不能播放了，安卓都好使，返回值返回了  “播放成功”  ，但IOS就是无法播放，请问是什么问题！
