动态单选按钮uitableview自定义单元格ios

我想使用自定义单元格创建动态单选按钮。我尝试并能够使用故事板创建。 但如何只允许一个单选按钮选择？

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { MChangeServiceTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"changeServiceCellidentifier"]; cell.serviceLabelView.text =@"test"; cell.radioButton.tag=indexPath.row; [cell.radioButton addTarget:self action:@selector(radioButtonColorChange:) forControlEvents:UIControlEventTouchUpInside]; return cell; } - (void)radioButtonColorChange:(id)sender { UIButton *button=(UIButton *) sender; NSIndexPath *indexpath = [NSIndexPath indexPathForRow:button.tag inSection:0]; MChangeServiceTableViewCell *tappedCell = (MChangeServiceTableViewCell *)[self.listTableView cellForRowAtIndexPath:indexpath]; if ([tappedCell.radioButton.imageView.image isEqual:[UIImage imageNamed:@"radio_button_unselected.png"]]) { [tappedCell.radioButton setImage:[UIImage imageNamed:@"radio_button_selected.png"] forState:UIControlStateNormal]; } else { [tappedCell.radioButton setImage:[UIImage imageNamed:@"radio_button_unselected.png"] forState:UIControlStateNormal]; } } 

我可以通过点击它来更改单选按钮的图像。但是，当单击一个按钮时，如何将剩余的单选按钮更改为未选中状态？

我建议你将当前选中的按钮保存在另一个变量中。

 @interface YourViewController () @property (strong, nonatomic) UIButton *currentBtn; @property (nonatomic) NSInteger currentSelectedIndex; @end 

然后

 - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. _currentSelectedIndex = -1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { MChangeServiceTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"changeServiceCellidentifier"]; cell.serviceLabelView.text =@"test"; cell.radioButton.tag=indexPath.row; [cell.radioButton setImage:[UIImage imageNamed:@"radio_button_selected.png"] forState:UIControlStateSelected]; [cell.radioButton setImage:[UIImage imageNamed:@"radio_button_unselected.png"] forState:UIControlStateNormal]; [cell.radioButton addTarget:self action:@selector(radioButtonColorChange:) forControlEvents:UIControlEventTouchUpInside]; [cell.radioButton setSelected:NO]; if (indexPath.row == _currentSelectedIndex) { [cell.radioButton setSelected:YES]; _currentBtn = cell.radioButton; } return cell; } - (void)radioButtonColorChange:(id)sender { _currentBtn.selected = NO; UIButton *button=(UIButton *) sender; button.selected = !button.isSelected; _currentBtn = button; _currentSelectedIndex = button.tag; }
