Objective c UITextField和UIImageView重叠表视图

我有以下问题，UITextField和UIImageView与tableView重叠。如果我先选择位置，然后返回选择活动，则位置的

UItextfield

将与活动重叠

tableView

代码

更改cofigureAutoComTableView方法中的Tableview框架，方法如下：autocompleteTableView=[[UITableView alloc]initWithFrame:CGRectMake（self.txtActivity.frame.origin.x，CGRectGetHeight（self.txtActivity.frame）+40，txtActivity.frame.size.width，200）style:UITableViewStylePlain]；不起作用，它仍然是一样的。尝试这种方式autocompleteTableView=[[UITableView alloc]initWithFrame:CGRectMake（self.txtActivity.frame.origin.x，CGRectGetHeight（\u txtPlaceSearch.frame）+40，\u txtActivity.frame.size.width，200）style:UITableViewStylePlain]@RajeshDharani，尝试了你的最新建议，tableView出现在文本字段的后面；
