scrollView的用法

- ( void )viewDidLoad

{

     [super viewDidLoad];

     

     scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];

     scrollView.backgroundColor = [UIColor redColor];

     // 是否支持滑動最頂端

//    scrollView.scrollsToTop = NO;

     scrollView.delegate = self;

     // 設置內容大小

     scrollView.contentSize = CGSizeMake(320, 460*10);

     // 是否反彈

//    scrollView.bounces = NO;

     // 是否分頁

//    scrollView.pagingEnabled = YES;

     // 是否滾動

//    scrollView.scrollEnabled = NO;

//    scrollView.showsHorizontalScrollIndicator = NO;

     // 設置indicator風格

//    scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;

     // 設置內容的邊緣和Indicators邊緣

//    scrollView.contentInset = UIEdgeInsetsMake(0, 50, 50, 0);

//    scrollView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 50, 0, 0);

     // 提示用戶,Indicators flash

     [scrollView flashScrollIndicators];

     // 是否同時運動,lock

     scrollView.directionalLockEnabled = YES;

     [self.view addSubview:scrollView];

     

     UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 200, 320, 40)];

     label.backgroundColor = [UIColor yellowColor];

     label.text = @ "學習scrolleview" ;

     [scrollView addSubview:label];

     [label release];
