Xcode: How to go to specific position in a scrollview
提问by Clarence
I am having problem when making a long scroll view with images. It will be difficult for users to scroll down for so long to get to that image or button. Is there any ways that i can create some buttons on the top of the scroll view, while pressing these buttons that can directly scroll down to the specific position that i want? (scroll down animated will be good)
使用图像制作长滚动视图时遇到问题。用户很难向下滚动这么长时间才能找到该图像或按钮。有什么方法可以在滚动视图的顶部创建一些按钮，同时按下这些按钮可以直接向下滚动到我想要的特定位置？（向下滚动动画会很好）
Many thanks.
非常感谢。

- (IBAction) yourBtnInScrollViewPressed : (id) sender
{
[yourScrollView scrollRectToVisible:CGRectMake(x, y, yourScrollView.frame.size.width, yourScrollView.frame.size.height) animated:YES];
}
