问题
I am currently researching ways of adding several UIImageView to a single UIScrollView. The UIScrollView will be 1.5 times the size of any one of the UIImageViews. I want to create a scrolling effect for browsing through some small images in an iPad application. Does anyone know how to achieve this?
回答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];

If you want zoom and everything:

If you just want a paging scrollview:
