iphone - 我误会了reloadRowsAtIndexPaths :

我有一个分组表 View ，我想在其中重新加载特定的行。当我调用reloadRowsAtIndexPaths时:该行从表 View 中完全消失。还有什么我需要做的吗？

//this is the method doing the reload
-(void)setDurationTableViewCell:(NSString *)dur {

    self.workoutDuration = dur;
    NSIndexPath *durPath = [NSIndexPath indexPathForRow:3 inSection:0];
    NSArray *paths = [NSArray arrayWithObject:durPath];
    [woTableView reloadRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationRight];

}//end setDurationTableViewCell


//this is the cellForRowAtIndexPath method if it has anything to do with my issue
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell;

    if (indexPath.row == 0) {

        //workout comments
        cell = [tableView dequeueReusableCellWithIdentifier:@"workoutCommentsCell"];
        if (nil == cell) {
            cell = workoutCommentsCell;
            cell.selectionStyle = UITableViewCellStyleValue1;
        }

    }else if (indexPath.row == 1) {

        //difficulty
        cell = [tableView dequeueReusableCellWithIdentifier:@"workoutDifficultyCell"];
        if (nil == cell) {
            cell = workoutDifficultyCell;
            cell.selectionStyle = UITableViewCellStyleValue1;
        }
        cell.textLabel.text = [NSString stringWithFormat:@"Difficulty: %@", self.workoutDifficulty];

    }else if (indexPath.row == 2) {

        //workoutDate
        cell = [tableView dequeueReusableCellWithIdentifier:@"workoutDateCell"];
        if (nil == cell) {
            cell = workoutDateCell;
            cell.selectionStyle = UITableViewCellStyleValue1;
        }
        cell.textLabel.text = [NSString stringWithFormat:@"Date: %@", self.workoutDate];

    }else if (indexPath.row == 3) {

        //workoutDuration
        cell = [tableView dequeueReusableCellWithIdentifier:@"workoutTimerCell"];
        if (nil == cell) {
            cell = workoutTimeCell;
            cell.selectionStyle = UITableViewCellStyleValue1;
        }
        cell.textLabel.text = [NSString stringWithFormat:@"Duration: %@", self.workoutDuration];

    }//end else-if


    return cell;

}//end cellForRowAtIndexPath

最佳答案

尝试将ReloadRowsAtIndexPaths包装在其中

[self.tableView beginUpdates];
[self.tableView endUpdates];

例如

[self.tableView beginUpdates];
[woTableView reloadRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationRight];
[self.tableView endUpdates]
