Question

我需要实现页面滚动视图。每个页面视图应加载一个单独的视图控制器。在视图控制器上执行操作/事件时应更新/刷新页面视图。是否可能？如果有，怎么样？如果你能够在这方面给我指点，那将非常感激。

Answer 1

-(void)createScrollView
{
myScroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 440)];
myScroll.pagingEnabled = YES;
myScroll.showsHorizontalScrollIndicator = YES;
myScroll.showsVerticalScrollIndicator = YES;
myScroll.scrollsToTop = NO;
myScroll.delegate = self;
int n = [array count];
myScroll.contentSize = CGSizeMake((320 * n), 440); // n = number of views

for (int i = 0 , X = 0; i < [photoArray count]; i++ , X += 320) 
{
    UIImageView *img =[[UIImageView alloc]initWithFrame:CGRectMake(X,0, 320, 480)]; //here view for you

    CGRect frame;
    frame.size.width=320; frame.size.height=240;
    frame.origin.x=0; frame.origin.y=88;


    [img addSubview:asyncImage];
    img.contentMode=UIViewContentModeScaleAspectFit;            

    [myScroll addSubview:img];
}
}

 - (void) viewDidLoad
  {
[self createScrollView];
[myScroll scrollRectToVisible:CGRectMake(320*photoNumber, 0, 320 , 240) animated:NO];
[self.view addSubview:myScroll];        
  }

它的示例代码....尝试改变...希望最终为你工作......
