如何使用编程动态设置UIScrollview高度

Question

我用过UIScrollview我的iPhone app.我已将默认大小设置为UIScrollview 320 * 548.我想UIScrollview通过编程动态增加高度,但我还没有成功.我用过以下代码

 CGRect scrollFrame;

scrollFrame.origin = _tblScroolView.frame.origin;

scrollFrame.size = CGSizeMake(320, 700);

_tblScroolView.frame = scrollFrame; 

请帮我

谢谢!

要更改滚动视图的大小

scrollView.frame = CGRectMake(originX, originY, width, height);

更改可滚动区域的大小:

scrollView.contentSize = CGSizeMake(width, height);

Swift 3版

scrollView.frame = CGRect(x: scrollX, y: scrollY, width:width, height:height)

scrollView.contentSize = CGSize(width:width, height: height)
