滑動相關(guān)代理方法

// 視圖已經(jīng)放大或縮小
 - (void)scrollViewDidZoom:(UIScrollView *)scrollView
 {
    NSLog(@"scrollViewDidScrollToTop");
 }

// 是否支持滑動至頂部
- (BOOL)scrollViewShouldScrollToTop:(UIScrollView *)scrollView
{
    return YES;
}

// 滑動到頂部時(shí)調(diào)用該方法
- (void)scrollViewDidScrollToTop:(UIScrollView *)scrollView
{
    NSLog(@"滑動到頂部時(shí)調(diào)用該方法");
}

// scrollView 已經(jīng)滑動
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
    NSLog(@"已經(jīng)滑動");
}

// scrollView 開始拖動
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView
{
    NSLog(@"開始拖動");
}

// scrollView 結(jié)束拖動
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
{
    NSLog(@"結(jié)束拖動");
}

// scrollView 開始減速（以下兩個(gè)方法注意與以上兩個(gè)方法加以區(qū)別）
- (void)scrollViewWillBeginDecelerating:(UIScrollView *)scrollView
{
    NSLog(@"開始減速");
}

// scrollview 減速停止
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    NSLog(@"減速停止");
}

放大縮小視圖相關(guān)代理方法

  //返回一個(gè)放大或者縮小的視圖
 - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView
 {

 }
  //開始放大或者縮小
 - (void)scrollViewWillBeginZooming:(UIScrollView *)scrollView withView:
 (UIView *)view
 {
 
 }

  //縮放結(jié)束時(shí)
 - (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale
 {
 
 }
