推荐答案

你将拥有手动更改 UITableView 的 contentOffset 。请务必考虑 contentInset.top 。它应该是一样简单：

You'll have to manually change the contentOffset of your UITableView yourself. Be sure to account for the contentInset.top. It should be something as simple as:

CGPoint newOffset = CGPointMake(0, -[myTableView contentInset].top);
[myTableView setContentOffset:newOffset animated:YES];
