I am using the following code to show some labels and a textview in a tableview. But the problem is some textviews overwriting at some unwanted places while scrolling. Please help me . Thanks in advance

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

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    cell.selectionStyle                                         =   UITableViewCellSelectionStyleNone;
    cell.backgroundColor=[UIColor whiteColor];
    if (indexPath.row==0) 
    {
        UILabel *Sender = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 200, 20)];
        Sender.text=@"From Time";
        Sender.textColor=[UIColor colorWithRed:77.0/255.0 green:104.0/255.0 blue:159.0/255.0 alpha:1.0]; 
        Sender.font=[UIFont fontWithName:@"verdana" size:16];
        [cell addSubview:Sender];
        [Sender release];  

    }

    if (indexPath.row==1) 
    {
        UILabel *Sender = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 200, 20)];
        Sender.text=@"Sender";
        Sender.textColor=[UIColor colorWithRed:77.0/255.0 green:104.0/255.0 blue:159.0/255.0 alpha:1.0]; 
        Sender.font=[UIFont fontWithName:@"verdana" size:16];
        [cell addSubview:Sender];
        [Sender release];  
        UILabel *Label = [[UILabel alloc] initWithFrame:CGRectMake(30, 35, 200, 20)];
        Label.text=@"Achuthananthan";
        Label.font=[UIFont fontWithName:@"verdana" size:14];
        [cell addSubview:Label];
        [Label release]; 
    }
    if (indexPath.row==2) 
    {
        UILabel *Agenda = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 200, 20)];
        Agenda.text=@"Agenda";
        Agenda.textColor=[UIColor colorWithRed:77.0/255.0 green:104.0/255.0 blue:159.0/255.0 alpha:1.0]; 
        Agenda.font=[UIFont fontWithName:@"verdana" size:16];

        [cell addSubview:Agenda];
        [Agenda release]; 
        UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(20, 30, 280, 120)];
        textView.editable=NO;
        textView.text=[NSString stringWithString:@"Lorem ipsum dolor sit er elit lamet, consectetaur cillium adipisicing pecu, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

推荐答案

使用此代码...

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

static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    cell.selectionStyle =   UITableViewCellSelectionStyleNone;
        cell.backgroundColor=[UIColor whiteColor];

 UILabel *Sender = [[UILabel alloc] initWithFrame:CGRectMake(20, 10, 200, 20)];
     [sender setTag:500];
Sender.font=[UIFont fontWithName:@"verdana" size:16];
    Sender.textColor=[UIColor colorWithRed:77.0/255.0 green:104.0/255.0 blue:159.0/255.0 alpha:1.0]; 
    [cell addSubview:Sender];
    [Sender release];  

    UILabel *Label = [[UILabel alloc] initWithFrame:CGRectMake(30, 35, 200, 20)];
    Label.text=@"Achuthananthan";
    Label.font=[UIFont fontWithName:@"verdana" size:14];
    [Label setTag:600];
    [cell addSubview:Label];
    [Label release]; 

UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(20, 30, 280, 120)];
    textView.editable=NO;
[Label setTag:700];
    textView.text=[NSString stringWithString:@"Lorem ipsum dolor sit er elit lamet, consectetaur cillium adipisicing pecu, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. Nam liber te conscient to factor tum poen legum odioque civiuda."];
    textView.font=[UIFont fontWithName:@"verdana" size:14];
    [cell addSubview:textView];
    [textView release];

}

UILabel *firstLabel = (UILabel*)[cell viewWithTag:500];
UILabel *SecondLabel = (UILabel*)[cell viewWithTag:600];
UITextView *firstText = (UITextView*)[cell viewWithTag:700];

if (indexPath.row==0) 
{

    firstLabel.text=@"From Time";
[SecondLabel setHidden:Yes];
[firstText setHidden:Yes];

}

if (indexPath.row==1) 
{

    firstLabel.text=@"Sender";
[SecondLabel setHidden:NO];
[firstText setHidden:Yes];

}
if (indexPath.row==2) 
{
    firstLabel.text=@"Agenda";
[SecondLabel setHidden:Yes];
[firstText setHidden:NO]; 
}
return cell;
 }
