我目前正在为我的客户端在iOS上开发应用程序。我遇到了一个我无法解决的特定问题。
我正在以编程方式将视图添加到uiview内部(滚动视图内部)的stackview中。
stackview内部的视图应具有不同的高度,具体取决于添加到stackview内部每个视图内部的标签的内容。
某些标签将包含html属性文本。 uistackview的某些子视图将包含使用翠鸟库在运行时从Internet下载的图像。
请帮助我。
设置框架,边界等不起作用。 使用“ setNeedsLayout”,“ layoutIfNeeded”,“ layoutSubViews”无济于事,并且不起作用。

我尝试使用tableview和自动标注,但在第一次加载时未正确调整子视图的大小。在第二次加载时还可以。标签,高度不正确以及下载的图像存在问题。因此,我发现无需使用Tableview就可以以编程方式执行此操作。我有5个不同的复杂uitableviewcell。有些包含许多标签和图像,有些仅包含标签。我尝试了一切,但没有成功:(
