Question

我必须解决一个iOS错误，当手机没有互联网连接时，图像会消失。

采取的步骤如下：

打开应用
转到其中一个选项（例如，以红色标注的选项）
- Screenshot 1
返回到屏幕，图像消失了（只有文字忍受了）。
- Screenshot 2

这很奇怪，因为当设备处于＆＃34;监督之下时＃34;野生动物园检查，它就像魔法一样。

我在其他版本的应用程序中使用相同的代码，但这并没有发生。我对代码进行了比较，并没有任何区别！

这是我的代码

Answer 1

你将使用web + cache for image。

[imageView setImageWithURL：[NSURL URLWithString：profilePictureUrl] placeholderImage：[UIImage imageNamed：@“placeholder.png”]];
