iphone - 具有自动滚动功能的 ScrollView

Question

我希望 ScrollView (或 TextView )自动滚动，就像在显示电影演职员表时一样。我尝试了几种方法，但都没有成功，我似乎找不到足够的答案，任何帮助将不胜感激!!

提前致谢!

此代码将在 10 秒内将 UIScrollView 滚动 100pt:

self.scrollView.scrollEnabled = NO;

CGFloat scrollHeight = 100;
[UIView animateWithDuration:10
                      delay:0
                    options:UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction
                 animations:^{
                     self.scrollView.contentOffset = CGPointMake(0, scrollHeight);
                 }
                 completion:nil];
