iphone - 为什么 UIScrollView 不称它为委托？

Question

问题是我在 Xib 制作了一个新的 UIScrollView，然后将委托链接到所有者.. 一些委托如何调用.. 任何线索？或 UIScrollView 的简单示例

对不起，我是一个新的 ios 开发人员，提前感谢..

编码 ：

在标题

@interface stageViewController : UIViewController<UIScrollViewDelegate>

在.m

#pragma mark drag delegate
- (void)scrollViewDidScroll:(UIScrollView *)scrollView{
    NSLog(@"scrollViewDidScroll");
}                                              // any offset changes
- (void)scrollViewDidZoom:(UIScrollView *)scrollView{
    NSLog(@"scrollViewDidZoom");
}

// called on start of dragging (may require some time and or distance to move)
- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView{
    NSLog(@"scrollViewWillBeginDragging");
}

- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset{
    NSLog(@"scrollViewWillEndDragging");
}

- (void)scrollViewWillBeginDecelerating:(UIScrollView *)scrollView{
    NSLog(@"scrollViewWillBeginDecelerating");
}

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{
    NSLog(@"scrollViewDidEndDecelerating");
}

写scrollView.delegate = self;如果你务实地做到了。如果你有你ScrollView的，XIB那么ctrl+drag从你的scrollView到你的File's Owner，然后设置它的代表。
