downFile域名白名单已加, 没有勾选 不校验域名,我自己使用downFile也成功的,应该不是这个问题 但是真机上图片出不来,文字是显示了,排版也正常 模拟器上是可以的 还有什么问题导致? 有个lifecycle事件用处是什么? 可以看下下面的代码哪里有问题

1、图片问题,把dist里的easyCanvas.min.js替换examle/weapp里的,之前example里面的有可能没更新,现在已经更新了,如果还是不可以,请提供下系统版本和微信版本,目前有反馈 ios 微信7.0.20 版本api有问题
2、lifecycle里目前的两个生命周期都是针对有绘制网络图片的情况的,图片请求成功并且绘制成功触发onEffectSuccess
Sorry, something went wrong.
是问题1导致的,目前已OK

但是真机上图片出不来,文字是显示了,排版也正常
模拟器上是可以的
还有什么问题导致?
有个lifecycle事件用处是什么?
可以看下下面的代码哪里有问题
