问题描述
我想在图像视图中显示图像(宽度:320 像素,高度:1250 像素).
I would like to display an image (width: 320 pixels, height: 1250 pixels) in an image view.
当我编译应用程序时,我根本没有滚动.视图保持不变.
When I compile the application I get no scrolling at all. The view stays fixed.
我做了什么:
- 通过 Interface Builder 在我的视图中添加了一个 UIScrollView.
- 通过 Interface Builder 向我的视图添加了一个 UIImageView.
- 验证 UIImageView 在 Interface Builder 中位于 UIScrollView 之下.
- 使用 ViewDidLoad 设置 UIScrollView 的大小.
- Added an UIScrollView via Interface Builder to my view.
- Added an UIImageView via Interface Builder to my view.
- Verified that UIImageView is below UIScrollView in Interface Builder.
- Set the size of the UIScrollView with ViewDidLoad.
我该怎么做?
代码:
- (void)viewDidLoad { [super viewDidLoad]; scrollView.contentSize = CGSizeMake(320, 1250); }

推荐答案
我刚刚做了同样的任务..试试这个.....
I just have done the same task.. Try this one.....
scrollView.delegate = self; scrollView.scrollEnabled = YES; int scrollWidth = 120; scrollView.contentSize = CGSizeMake(scrollWidth,80); int xOffset = 0; imageView.image = [UIImage imageNamed:[imagesName objectAtIndex:0]]; for(int index=0; index < [imagesName count]; index++) { UIImageView *img = [[UIImageView alloc] init]; img.bounds = CGRectMake(10, 10, 50, 50); img.frame = CGRectMake(5+xOffset, 0, 50, 50); NSLog(@"image: %@",[imagesName objectAtIndex:index]); img.image = [UIImage imageNamed:[imagesName objectAtIndex:index]]; [images insertObject:img atIndex:index]; scrollView.contentSize = CGSizeMake(scrollWidth+xOffset,110); [scrollView addSubview:[images objectAtIndex:index]]; xOffset += 70; }
也设置这个....
imagesName = [[NSArray alloc]initWithObjects:@"image1.jpg",@"image2.jpg",@"image3.jpg",@"image4.jpg",@"image5.jpg",@"image6.png",@"image7.png",@"image9.png",nil]; images = [[N**utableArray alloc]init];
