iOS UITableViewController 添加一个固定的不能滚动的控件

添加一个button 等宽与视图的宽度

    tryButton = [UIButtonbuttonWithType:UIButtonTypeCustom];

    tryButton.frame =CGRectMake(0,self.view.frame.size.height-44,self.view.frame.size.width,44);

    // [tryButton setBackgroundImage:[UIImage imageNamed:@""] forState:UIControlStateNormal];

    [tryButtonsetBackgroundColor:[UIColorredColor]];

    [tryButtonaddTarget:selfaction:@selector(tryButtonAction)forControlEvents:UIControlEventTouchUpInside];

    [self.view addSubview:tryButton];

添加在scrollView方法里设置坐标即可

-(void)scrollViewDidScroll:(UIScrollView *)scrollView

{

    tryButton.frame =CGRectMake(0, (self.tableView.frame.size.height - 150) + self.tableView.contentOffset.y , tryButton.frame.size.width,tryButton.frame.size.height);

}
