UIScrollView的基本属性设置和常用代理方法

罗列了UIscrollView的一些基本设置和常用方法

• (void)viewDidLoad { [super viewDidLoad]; // [self initScrollView]; // [self initPageCtrl]; // [self addTimer]; self.scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(10, 20, 320, 460)]; self.scrollView.backgroundColor = [UIColor blueColor]; //是否支持滑动到最顶端 self.scrollView.scrollsToTop = NO; //设置UIScrollView的代理 self.scrollView.delegate = self; //设置内容大小 self.scrollView.contentSize = CGSizeMake(320 * 10, 460); //是否反弹 self.scrollView.bounces = NO; //是否滚动 self.scrollView.scrollEnabled = YES; //是否分页 self.scrollView.pagingEnabled = NO; //设置indecator风格 self.scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite; //设置内容边缘和Indicator边缘 self.scrollView.contentInset = UIEdgeInsetsMake(0, 50, 50, 0); self.scrollView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 50, 0, 0); //是否同时运动 self.scrollView.directionalLockEnabled = NO;

    [self.view addSubview:self.scrollView];
  

  }

  //是否支持滑动到顶部

  • (BOOL) scrollViewShouldScrollToTop:(UIScrollView *)scrollView { return YES; }

  //滑动到顶部时调用该方法

  • (void) scrollViewDidScrollToTop:(UIScrollView *)scrollView { NSLog(@“滑动到顶部了”); }

  //已经滑动(正在滑动也会调用该方法)

  • (void) scrollViewDidScroll:(UIScrollView *)scrollView { NSLog(@“已经开始滑动”); }

  //开始拖动

  • (void) scrollViewWillBeginDragging:(UIScrollView *)scrollView { NSLog(@“开始拖动”); }

  //结束拖动

  • (void) scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate { NSLog(@“结束拖动”); }

  //开始减速

  • (void) scrollViewWillBeginDecelerating:(UIScrollView *)scrollView { NSLog(@“开始减速”); }

  //减速停止

  • (void) scrollViewDidEndDecelerating:(UIScrollView *)scrollView { NSLog(@“减速停止”); }

  //结束滚动动画

  • (void) scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView { NSLog(@“结束滚动动画”); }

  • (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. }
