Sideview tableview覆蓋在iphone中的Textview

Question

我使用下面的代碼來顯示tableview中的一些標籤和textview。但問題是一些textviews在滾動時在一些不需要的地方覆蓋。請幫幫我 。在此先感謝

- (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. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

     textView.font=[UIFont fontWithName:@"verdana" size:14]; 
     [cell addSubview:textView]; 

     [textView release]; 

    } 
    return cell; 
}

使用此代碼...

- (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; 
}

移動，如果你想添加一個UILabel做以下

UILabel *label; 
if (cell == nil) { 
    //create the cell 
    //Create the label 
    //Give the label a tag 
    label.tag = 111; //for example 
    //add label to the cell 
    [cell.contentView addSubView:label]; 
} 

//Now get the label of the cell 
label = (UILabel*) [cell viewWithTag:111]; 

重複此爲所有的UILabels，增加了if (cell == nil) {部分
