UIView Frame Size 没有改变 UIImageView 放在里面 [英] UIView Frame Size Didn't Change UIImageView Placed inside it

问题描述

我在框架中制作图片，然后用户可以在运行时调整框架大小.为此，我在主 UIViewController 中创建了一个自定义 UIView，并在此 UIView 中放置了 2 个 UIImageView.在 xCode 的文档大纲窗格中，它的层次结构是:

I'm making a picture in a frame and then user can resize the frame size in runtime. For this purpose I've made a custom UIView in my main UIViewController and inside this UIView I've placed 2 UIImageView. In Document Outline Pane of xCode it's hierarchy is:

视图
|--ImageView
|--ImageView

View
|--ImageView
|--ImageView

我使用这行代码来改变 UIView 在不同条件下的大小，它会相应地调整大小:

I'm using this line of code to change size of UIView under different conditions it'll resize accordingly:

self.imageObject.frame = CGRectMake(self.imageObject.frame.origin.x , 
                                    self.imageObject.frame.origin.y, 
                                    200, 
                                    200);

imageObject 是我的 UIView.当我运行它时，UIView 的大小发生了变化，但 UIImageView 的大小保持不变.我也试过对我的 UIImageView 做同样的事情，但没有奏效.

imageObject is my UIView. When I run it the size of the UIView changes but UIImageView size remains the same. I've also tried doing the same for my UIImageView but it didn't work.

推荐答案

你也可以试试这个 :-

You can also Try This :-

imageView.frame = CGRectMake(0,0,imageObject.frame.size.width, imageObject.frame.size.height);
imageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
self.imageShw.contentMode = UIViewContentModeScaleAspectFit;
