ios – UITableView,替换选择时的单元格视图

@property (nonatomic,strong) NSIndexPath *selectedindexPath;

将NSIndexPath类型的属性设置为控制器以存储选择的索引路径.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    self.selectedindexPath = indexPath;
    [tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation: UITableViewRowAnimationNone];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    if ([indexPath compare:self.selectedindexPath] == NSOrderedSame) {
        // Create your custom cell here and return it.
    }
    else {
        // Should create a normal cell and return it.
    }
}

究竟.另请注意,您可能想要取消选择.这是Swift中的完整代码.根据需要在cellForRowAtIndexPath中使用selectedindexPath.

//选择TableViewController
导入UIKit

class SelectingTableViewController：UITableViewController

内部var selectedindexPath：NSIndexPath？ =没有

override func viewDidLoad()
    {
    super.viewDidLoad()
    tableView.estimatedRowHeight = 68.0
    tableView.rowHeight = UITableViewAutomaticDimension

    self.cleaRSSelectionOnViewWillAppear = false;
    }

override func tableView
    (tableView:UITableView,didSelectRowAtIndexPath indexPath:NSIndexPath)
        {
        print("did select....")

        // in fact,was this very row selected,// and the user is clicking to deselect it...
        // if you don't want "click a selected row to deselect"
        // then on't include this clause.
        if selectedindexPath == indexPath
            {
            print("(user clicked on selected to deselect)")
            selectedindexPath = nil

            }

        // in fact,was some other row selected??
        // user is changing to this row? if so,also deselect that row
        if selectedindexPath != nil
            {
            let pleaseRedrawMe = selectedindexPath!
            // (note that it will be drawn un-selected
            // since we're chaging the 'selectedindexPath' global)

            }

        // no prevIoUs selection.
        // simply select that new one the user just touched.
        // note that you can not use Apple's willdeselectRowAtIndexPath
        // functions ... because they are freaky
        selectedindexPath = indexPath
