安卓端没问题，但是ios端 请求后台实时坐标数据后设置rotate时没有效果刚开始转了一下后就还原图片不旋转了，下面是具体代码

self.data.setInter = setInterval(function() {

wx.request({

url: app.globalData.baseUrl

data: {

car_id: self.data.id,

api_token: wx.getStorageSync(“token”)

},

method: ‘GET’, // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT

header: {

‘content-type’: ‘application/json’

}, // 设置请求的 header

success: function(res) {

if (res.statusCode == 200) {

self.data.carPosition.push(res.data);

console.log(res.data);

}

var postionData = self.data.carPosition.shift();

var pos_x = (postionData[0] - 82) * 0.417 / 750 * wx.getSystemInfoSync().windowWidth;

var pos_y = (postionData[1] - 2630) * 0.455 / 750 * wx.getSystemInfoSync().windowWidth;

if (postionData[2] > 250 && postionData[2] < 271) {

self.animation.translate(pos_x, pos_y).step()

self.animation.rotate(450).step()

self.setData({

animation: self.animation.export(),

})

} else {

self.animation.translate(pos_x, pos_y).step()

self.animation.rotate(90).step()

self.setData({

animation: self.animation.export(),

})

}

}, 300)
