UIScrollView基本使用

 - (void)viewDidLoad
 {
     [super viewDidLoad];

     scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(, , , )];
     scrollView.backgroundColor = [UIColor redColor];
     // 是否支持滑动最顶端
 //    scrollView.scrollsToTop = NO;
     scrollView.delegate = self;
     // 设置内容大小
     scrollView.contentSize = CGSizeMake(, *);
     // 是否反弹
 //    scrollView.bounces = NO;
     // 是否分页
 //    scrollView.pagingEnabled = YES;
     // 是否滚动
 //    scrollView.scrollEnabled = NO;
 //    scrollView.showsHorizontalScrollIndicator = NO;
     // 设置indicator风格
 //    scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
     // 设置内容的边缘和Indicators边缘
 //    scrollView.contentInset = UIEdgeInsetsMake(0, 50, 50, 0);
 //    scrollView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 50, 0, 0);
     // 提示用户,Indicators flash
     [scrollView flashScrollIndicators];
     // 是否同时运动,lock
     scrollView.directionalLockEnabled = YES;
     [self.view addSubview:scrollView];

     UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(, , , )];
     label.backgroundColor = [UIColor yellowColor];
     label.text = @"学习scrolleview";
     [scrollView addSubview:label];
     [label release];
 }
