iOStableView⾃定义单选cell和多选cell单选的效果⼤概就是这样，如果想设置右边的accessoryType属性，更改对应的UITableViewCellAccessoryType参数即可。1.先定义⼀个NSIndexPath ⽤于保存最后⼀次选中的组⾏NSIndexPath * _lastSelectIndexPath;的代理⽅法- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;{UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];if(cell == nil){cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];oundColor = [UIColor whiteColor]; = [UIFont systemFontOfSize:12];}if([_lastSelectIndexPath isEqual:indexPath]){//设置选中图⽚ = [UIImage imageNamed:@"icon_ssselected"];}else {//设置未选中图⽚ = [UIImage imageNamed:@"icon_unselected"];} = [NSString stringWithFormat:@"Cell%ld",];return cell;}- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;{UITableViewCell * lastSelectCell = [tableView cellForRowAtIndexPath: _lastSelectIndexPath];if (lastSelectCell != nil) { = [UIImage imageNamed:@"icon_unselected"];}UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; = [UIImage imageNamed:@"icon_ssselected"];_lastSelectIndexPath = indexPath;}多选，其实和单选差不多，只是将⽤于保存最后⼀次选中的NSIndexPath 换成数组就⾏了1.定义⼀个数组⽤于保存选中的NSIndexPath

NSMutableArray * _selectArr;数组记得初始化的代理⽅法- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;{UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];if(cell == nil){cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];oundColor = [UIColor whiteColor]; = [UIFont systemFontOfSize:12];}if([_selectArr containsObject:indexPath]){//设置选中图⽚ = [UIImage imageNamed:@"icon_ssselected"];}else {//设置未选中图⽚ = [UIImage imageNamed:@"icon_unselected"];} = [NSString stringWithFormat:@"Cell%ld",];return cell;}- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;{UITableViewCell * cell = [tableView cellForRowAtIndexPath:indexPath];if([_selectArr containsObject:indexPath]){[_selectArr removeObject:indexPath]; = [UIImage imageNamed:@"icon_unselected"];}else {[_selectArr addObject:indexPath]; = [UIImage imageNamed:@"icon_ssselected"];}}
