如何使UIScrollView立即停止？

Question

我只想滚动一页然后到另一页。

我设置了m_pScrollView.pagingEnabled = YES和m_pScrollView.bounces = NO，但是当我滚动到页面的边缘时，页面范围会退出，然后返回，如惯性效果。

我只是希望它scoll只有一个页面不多。谁能帮我？

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    m_pScrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 768, 1024)]; 
    m_pScrollView.delegate = self; 
    m_pScrollView.contentSize = CGSizeMake(768 * 3, 1024); 
    m_pScrollView.pagingEnabled = YES; 
    m_pScrollView.bounces = NO; 
    m_pScrollView.alwaysBounceHorizontal = NO; 
    m_pScrollView.alwaysBounceVertical = NO; 


    Myview *myview = [[Myview alloc]initWithFrame:CGRectMake(0, 0, 768, 1024)]; 
    myview.backgroundColor = [UIColor redColor]; 

    Myview *myview2 = [[Myview alloc]initWithFrame:CGRectMake(768, 0, 768, 1024)]; 

    myview2.backgroundColor = [UIColor blueColor]; 
    Myview *myview3 = [[Myview alloc]initWithFrame:CGRectMake(768 * 2, 0, 768, 1024)]; 
    myview3.backgroundColor = [UIColor grayColor]; 


    [m_pScrollView addSubview:myview]; 
    [m_pScrollView addSubview:myview2]; 
    [m_pScrollView addSubview:myview3]; 
    [self.view addSubview:m_pScrollView]; 
}

必须设置内容大小这样

m_pScrollView.contentSize = CGSizeMake(x,y);
