Is there any way to add the UI elements to the contentView when laying out the

问题 How programmatically restart an iPhone app in iOS?

问题 Is it possibile add UIRefreshControl at the bottom of the UITableView ? I would use it to load more data. Please, Any suggest? 回答1: I believe there won't be any simple solution to this problem.

But let us break down the problem and that might help you in achieving what you want. I have used the following code to add more rows in the app: - (void
