如何在 UITableView Cell 中启用 UITextField userinteraction 属性

Question

我有 UITableViewCell，里面有 UITextfield，我做了 7 个部分（动态），每个部分有一个单元格（一行），其中包括 UITextField。

现在 UINavigationBar 的右上角有一个按钮（“编辑”按钮）。我需要为所有部分文本字段启用用户交互。这怎么可能？

这是我的UITableviewCode

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    sharedManager=[Mymanager sharedManager];
    return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //UITableViewCell *cell;
    UILabel *label = nil;
    NSString *text;
    cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
    if (cell == nil)
    {
        cell = [[timeLineDetailsCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"cell"];

        label = [[UILabel alloc] initWithFrame:CGRectZero];
        [label setLineBreakMode:UILineBreakModeWordWrap];
        [label setMinimumFontSize:FONT_SIZE];
        [label setNumberOfLines:0];
        [label setFont:[UIFont systemFontOfSize:FONT_SIZE]];
        [label setTag:1];

        [[label layer] setBorderWidth:2.0f];

        [[cell contentView] addSubview:label];

    }

    if(indexPath.section==0){
        text = [contents objectAtIndex:0];
    }else if(indexPath.section==1){
        text = [contents objectAtIndex:1];
    }else if(indexPath.section==2){
        text = [contents objectAtIndex:2];
    }else if(indexPath.section==3){
        text = [contents objectAtIndex:3];
    }else if(indexPath.section==4){
        text = [contents objectAtIndex:4];
    }else if(indexPath.section==5){
        text = [contents objectAtIndex:5];
    }else if(indexPath.section==6){
        text = [contents objectAtIndex:6];
    }else if(indexPath.section==7){
        text = [contents objectAtIndex:7];
    }

    CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);

    CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

    if (!label)
        label = (UILabel*)[cell viewWithTag:1];

    [cell.ds1 setText:text];
    [cell.ds1 setFrame:CGRectMake(CELL_CONTENT_MARGIN, CELL_CONTENT_MARGIN, CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), MAX(size.height, 44.0f))];

    return cell;

}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
    NSString *text ;
    if(indexPath.section==0){
        text = [contents objectAtIndex:0];
    }else if(indexPath.section==1){
        text = [contents objectAtIndex:1];
    }else if(indexPath.section==2){
        text = [contents objectAtIndex:2];
    }else if(indexPath.section==3){
        text = [contents objectAtIndex:3];
    }else if(indexPath.section==4){
        text = [contents objectAtIndex:4];
    }else if(indexPath.section==5){
        text = [contents objectAtIndex:5];
    }else if(indexPath.section==6){
        text = [contents objectAtIndex:6];
    }else if(indexPath.section==7){
        text = [contents objectAtIndex:7];
    }


    CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);

    CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

    CGFloat height = MAX(size.height, 44.0f);

    return height + (CELL_CONTENT_MARGIN * 2);
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    NSString *str= [title objectAtIndex:section];
    return str;
}

我的编辑按钮代码是

-(void)editTimeline{
    cell.ds1.userInteractionEnabled=YES;
    [cell.ds1 setUserInteractionEnabled:TRUE];
    cell.ds1.layer.borderColor=[UIColor lightGrayColor].CGColor;
    cell.ds1.layer.borderWidth=1;
  //  [cell.ds1 becomeFirstResponder];

}

当我点击“编辑”按钮时，只有一些行可以编辑。请帮助我。

Answer 1

define flag data memeber with Bool type

-(void)editTimeline{
    flag=true;
     [self.tableView reload];
}


add following condition in cellForRowAtIndexpath method


if(flag==true){
 [cell.ds1 setUserInteractionEnabled:TRUE];
}
else{
 [cell.ds1 setUserInteractionEnabled:NO];
}

let me know if it help u....!!!

Answer 2

我会使用这个代码 -

    NSArray *cellArray=[itemsTable visibleCells];
    for (UITableViewCell *aCell in cellArray)
    {
        UITextField *myTField=(UITextField*)yourtextField;
        myTField.userInteractionEnabled=YES;
    }

myTField 作为带有特定标签的子视图添加到单元格中。您可以通过 [aCell viewWithTag:someTag];.

获得 myTField

Answer 3

为您的部分中的每一行调用 cellForRowAtIndexPath，使其无法被 tableView 选择（否则它会触发点击而不是您）并以您希望的方式为您返回的单元格启用用户交互：3
