TableView单元格0索引错误

Question

我有一个UITableViewCell 0索引上的四个按钮。我已经为像0,1,2,3这样的按钮设置了标签。 当我设置选择的属性没有0标记的按钮，它显示了以下错误：

-[UITableView set Selected:]: unrecognized selector sent to instance 

但对于其他按钮没有错误：

的代码是在这里：

UIButton *button1 = (UIButton *)[tableView viewWithTag:0]; 
    [button1 setSelected:NO]; 
    UIButton *button2 = (UIButton *)[tableView viewWithTag:2]; 
    [button2 setSelected:NO]; 
    UIButton *button3 = (UIButton *)[tableView viewWithTag:3]; 
    [button3 setSelected:NO]; 
    [button1 setBackgroundColor:[UIColor whiteColor]]; 
    [button2 setBackgroundColor:[UIColor whiteColor]]; 
    [button3 setBackgroundColor:[UIColor whiteColor]]; 

编辑的代码：

- (IBAction)click:(id)sender 
{ 
    UIButton *theButton = (UIButton *)sender; 
    UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview]; 
    NSIndexPath *clickedButtonPath = [tableView indexPathForCell:clickedCell]; 
    NSLog(@"hi...%d",clickedButtonPath.row); 
    if(theButton.tag==0) 
    { 
     theButton.selected=YES; 
     [theButton setBackgroundColor:[UIColor redColor]]; 
     UIButton *button1 = (UIButton *)[clickedCell viewWithTag:1]; 
     [button1 setSelected:NO]; 
     UIButton *button2 = (UIButton *)[clickedCell viewWithTag:2]; 
     [button2 setSelected:NO]; 
     UIButton *button3 = (UIButton *)[clickedCell viewWithTag:3]; 
     [button3 setSelected:NO]; 
     [button1 setBackgroundColor:[UIColor whiteColor]]; 
     [button2 setBackgroundColor:[UIColor whiteColor]]; 
     [button3 setBackgroundColor:[UIColor whiteColor]]; 

    } 
    else if(theButton.tag==1) 
    { 
     theButton.selected=YES; 
     [theButton setBackgroundColor:[UIColor redColor]]; 
     UIButton *button1 = (UIButton *)[clickedCell viewWithTag:0]; 
     [button1 setSelected:NO]; 
     UIButton *button2 = (UIButton *)[clickedCell viewWithTag:2]; 
     [button2 setSelected:NO]; 
     UIButton *button3 = (UIButton *)[clickedCell viewWithTag:3]; 
     [button3 setSelected:NO]; 
     [button1 setBackgroundColor:[UIColor whiteColor]]; 
     [button2 setBackgroundColor:[UIColor whiteColor]]; 
     [button3 setBackgroundColor:[UIColor whiteColor]]; 
    } 
    else if(theButton.tag==2) 
    { 
     theButton.selected=YES; 
     [theButton setBackgroundColor:[UIColor redColor]]; 
     UIButton *button1 = (UIButton *)[clickedCell viewWithTag:0]; 
     [button1 setSelected:NO]; 
     UIButton *button2 = (UIButton *)[clickedCell viewWithTag:1]; 
     [button2 setSelected:NO]; 
     UIButton *button3 = (UIButton *)[clickedCell viewWithTag:3]; 
     [button3 setSelected:NO]; 
     [button1 setBackgroundColor:[UIColor whiteColor]]; 
     [button2 setBackgroundColor:[UIColor whiteColor]]; 
     [button3 setBackgroundColor:[UIColor whiteColor]]; 
    } 

    else if(theButton.tag==3) 
    { 
     theButton.selected=YES; 
     [theButton setBackgroundColor:[UIColor redColor]]; 
     UIButton *button1 = (UIButton *)[clickedCell viewWithTag:0]; 
     [button1 setSelected:NO]; 
     UIButton *button2 = (UIButton *)[clickedCell viewWithTag:2]; 
     [button2 setSelected:NO]; 
     UIButton *button3 = (UIButton *)[clickedCell viewWithTag:1]; 
     [button3 setSelected:NO]; 
     [button1 setBackgroundColor:[UIColor whiteColor]]; 
     [button2 setBackgroundColor:[UIColor whiteColor]]; 
     [button3 setBackgroundColor:[UIColor whiteColor]]; 
    } 
}

访问您的按钮，这样

UIButton *button1 = (UIButton *)[cell viewWithTag:0]; 


UITableViewCell *clickedCell = (UITableViewCell *)sender;
