您需要设置contentSize滚动视图的属性才能使其正确滚动。如果您使用自动布局,你需要设置contentSize的viewDidLayoutSubviews,以便它的自动布局完成后应用。代码看起来像这样:-(void)viewDidLayoutSubviews{ // The scrollview needs to know the content size for it to work correctly self.scrollView.contentSize = CGSizeMake( self.scrollContent.frame.size.width, self.scrollContent.frame.size.height + 300 );}
