什么可能导致UIImageView中部分加载的JPEG？ [英] What might cause a partially loaded JPEG in a UIImageView?

问题描述

我们正在移动应用中获取部分加载的个人资料图片在iOS和Android领域的报告。

We are getting reports in the field, on both iOS and Android, of partially loaded profile images in our mobile app.

这是它的样子（注意我有高斯模糊的图像部分，以保护我们的成员的隐私，但灰色是实际呈现的）：

Here is what it looks like (note that I have gaussian blurred part of the image to protect the privacy of our members, but the grey is what is actually rendered):

AFAIK没有在UIImageView中加载渐进式JPEGS的概念所以我对这个图像甚至可以渲染的方式感到茫然。此代码至少在一年内未被修改。所有图像都托管在S3上，已经存在了2年。

AFAIK there is not a concept of loading "Progressive JPEGS" in UIImageView, so I am at a loss about how this image could even have been rendered at all. This code has not been modified in at least a year. All images are hosted on S3, and have been for 2 years.

如果设备达到某个带宽限制，运营商现在是否有可能截断图像？

Is it somehow possible that carriers are truncating images now if a device hits a certain bandwidth limit?

我可以确认我们能够在AT& T上重现此行为网络。当用户查看数据上限或其他内容时，AT& T是否可能以这种方式重置图像？

I can confirm we were able to repro this behavior on an AT&T network. Is it possible that AT&T is munging images in this fashion when a user goes over his data cap or something?

推荐答案

当我从https切换到http图像时，我出现了同样的问题。不用说......我切换回基于https的图像。

I had this same issue crop up when I switched from https to http images. Needless to say... I switched back to https based images.
