滚动视图中的图像 [英] Image In Scroll View

问题描述

我正在使用以下代码尝试在 UIScrollView 中显示图像.

I am using the following code to try and display an image in a UIScrollView.

[self.jarView addSubview:imgView];

它不起作用.但是，当我将子视图添加到我的普通视图时，它会起作用.我的 UIScrollView 被称为 jarView 和 imgView 是一个 UIImageView.

It does not work. However, it works when I add the subview to my normal view. My UIScrollView is called jarView and imgView is a UIImageView.

谢谢

推荐答案

这对我来说很好:

UIScrollView *scrollview;
scrollview= [[UIScrollView alloc] initWithFrame:CGRectMake(,,,)];// set scroll view size
view = [[UIView alloc] initWithFrame:CGRectMake(y1,x1,y2,x2)];  //set the view size
UIImage *image1 = [UIImage imageNamed:imageName];
image=[[UIImageView alloc]initWithImage:image1];// take image size according to view
[view addSubview:image];
[scrollview addSubview:view];
[view release];

最后定义scrollview滚动多少:

scrollview.contentSize = CGSizeMake(width,height);
