objective-c - 发生排序时取消选择表列

Question

我有一个应用程序，单击按钮即可加载表格，当前表格的排序选项已被删除，但是当我单击任何列然后单击表格标题时，应取消选择所选的列。不知道如何实现这一点。

提前致谢!!!

您必须触发“buttonSelected:”方法:)

 @interface ViewController () <UITableViewDataSource, UITableViewDelegate>

@property (nonatomic, strong) NSIndexPath *currentSelectedIndexPath;
@property (weak, nonatomic) IBOutlet UITableView *tableView;

@end

@implementation ViewController

#pragma mark - UIViewControllerDelegate

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
    self.currentSelectedIndexPath = nil;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    self.currentSelectedIndexPath = indexPath;
}

- (IBAction)buttonSelected:(UIButton *)sender {
    [self.tableView deselectRowAtIndexPath:self.currentSelectedIndexPath animated:YES];
}

@end
