   ###问题代码  image 动态设置宽高时，在ios  端 出现闪退现象 
   ``` javascript
    <image class="godds-image" v-for="(item,index) in detailImageList"  ref="img" @load="onImageLoad(index,$event)" :src="item" ></image>
   ```
   
   ``` javascript
   onImageLoad (index,event) {
         var that=this;
         if (event.success) {
           // Do something to hanlde success
           const view = that.$refs['img'];
           if (event.success){
               if (Utils.env.isWeb()){
                      
                       view[0].style.width= '10rem';
                       view[0].style.height= 10*event.size.naturalHeight/event.size.naturalWidth +'rem';
                   }else{
                       //  modal.toast({
                       //     message: '10rem',
                       //     duration: 0.3
                       // })
                   animation.transition(view[0],{
                       styles:{
                       width: '750px',
                       height: `${750*event.size.naturalHeight/event.size.naturalWidth}px`
                       },
                       duration: 0,//需要设置为0，否则无效
                       timingFunction:'ease',
                       delay: 100,
                       needLayout:true,//变化后刷新界面
                       }, function(){
                           console.log(1)
                       })
               }
           }
       }
     },
   ```
   > ### 开启 needLayout:true 直接闪退
