Ios 如何以编程方式为en和ar语言环境布局UIImageView，并在其上添加文本？

我正在尝试布局图像视图，标签就在它旁边。我得到了在英语语言环境下工作的布局，但它给出了以下错误约束。它无法在阿拉伯语模式下渲染，

UIImageView

未将其位置切换到右侧

然后在stackView中添加

profileHeaderView

。如何解决这个问题？

在这里使用嵌套的

UIStackView

s会更容易，这样约束问题就不会那么严重了。你想要的是

如果标签位于垂直视图中，则堆栈视图和图像位于水平视图中

在运行时，当用户切换到从右向左的区域设置时，删除图像并将其重新插入外部堆栈视图的末尾。从左向右切换时，请执行相反的操作

此处需要的唯一约束是图像的尺寸和最外层堆栈视图相对于其父对象的位置。堆栈视图的间距和对齐属性将替代嵌套项的约束
