將UIImageView添加到UIScrollView

Question

我目前正在研究將幾個UIImageView添加到單個UIScrollView的方法。 UIScrollView將是UIImageViews中任意一個的1.5倍。我想創建一個滾動效果來瀏覽iPad應用程序中的一些小圖像。有誰知道如何做到這一點？

Answer 1

UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(/*FRAME*/)]; // this makes the scroll view - set the frame as the size you want to SHOW on the screen 
[scrollView setContentSize:CGSizeMake(/*SIZE OF THE CONTENT*/)]; // if you set it to larger than the frame the overflow will be hidden and the view will scroll 

/* you can do this bit as many times as you want... make sure you set each image at a different origin */ 
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"/*IMAGE*/"]]; // this makes the image view 
[imageView setFrame:CGRectMake(/*SET AS 2/3 THE SIZE OF scrollView AND EACH IMAGE NEXT TO THE LAST*/)]; // this makes the image view display where you want it and at the right size 
[scrollView addSubview:imageView]; // this adds the image to the scrollview 
/* end adding image */ 

[self.view addSubview:scrollView];

如果你只是想尋呼滾動視圖：
