I've customized a UITableViewCell's contentView to have 2 labels.
However, when I select/highlight the cell the contentView seems to duplicate itself.
Here's an example (before):
After (highlighted):
Here's my code for the cell:
- (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];
}
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
UILabel *mainLabel = [[[UILabel alloc] init] autorelease];
UILabel *detailedLabel = [[[UILabel alloc] init] autorelease];
[mainLabel setFont:[UIFont boldSystemFontOfSize:18.0f]];
[detailedLabel setFont:[UIFont systemFontOfSize:13.0f]];
mainLabel.frame = CGRectMake(51, 5, 0, 0);
mainLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
detailedLabel.frame = CGRectMake(51, 23, 0, 0);
detailedLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
NSString *text = [documents objectAtIndex:indexPath.row];
mainLabel.text = [text stringByReplacingOccurrencesOfString:[NSString stringWithFormat:#".%#", [text pathExtension]] withString:#""];
NSString *extDescription = [self extensionDescriptionFromExtension:[text pathExtension]];
NSString *fileSize = [self getFileSize:[NSString stringWithFormat:#"%#/Documents/%#", documentsDirectory, text]];
detailedLabel.text = [NSString stringWithFormat:#"%# - %#", fileSize, extDescription];
cell.imageView.image = [UIImage imageNamed:#"txtIcon.png"];
[cell.contentView addSubview:mainLabel];
[cell.contentView addSubview:detailedLabel];
return cell;
}
Any help appreciated.
Got it working with UITableViewCellStyleSubtitle.

Oops,I am facing an issue with table view cells having no image,i.e. the cell with default image.Upon scrolling the default image disappears and some image from a cell is appearing on it.I have implemented the suggestion from Mr.Rckoenes here .Even then I was unable to fix the issue.Here is my implementation code for understanding:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
ReminderClass *reminderToDisplay = [self.remindersArray objectAtIndex:indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellIdentifier];
// Now create the cell to display the data
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:kCellIdentifier] autorelease];
cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
cell.textLabel.numberOfLines = 0;
cell.textLabel.font = [UIFont fontWithName:kHelvetica size:17.0];
cell.textLabel.adjustsFontSizeToFitWidth = YES;
cell.backgroundColor = [UIColor clearColor];
}
......
if (Image != nil)
{
UIImageView *imageView=[[UIImageView alloc] initWithFrame:CGRectMake(240, 3, 70, 63)];
imageView.backgroundColor=[UIColor clearColor];
[imageView setImage:Image];
cell.accessoryView = imageView;
[imageView release];
}
else
{
UIImageView *imageView=[[UIImageView alloc] initWithFrame:CGRectMake(240, 3, 70, 63)];
imageView.backgroundColor=[UIColor clearColor];
UIImage *defaultImage = [UIImage imageNamed:kDefaultImage];
[imageView setImage:defaultImage];
cell.accessoryView = imageView;
[imageView release];
}
cell.textLabel.text = reminderDetailsString;
return cell;
}
Can any one please help me,thanks in advance :)
just set dequeueReusableCellWithIdentifier to nil and also reuseIdentifier to nil like bellow..
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];
and
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];
and also add your other code in this if (cell == nil) if condition..
UPDATE:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

I have a UItableview with 10 cells.I need to display a message from an NSarray into this tableview.The array contains 3 items and needs to be displayed in the any of the 3 cells .
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
CustomTableView *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[ CustomTableView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
NSString *order = [orderArray objectAtIndex:indexPath.row];
NSString *sdate = [dateArray objectAtIndex:indexPath.row];
//Label positions
UILabel *ordernum = [[UILabel alloc] initWithFrame:CGRectMake(5,28,95,21)];
UILabel *date = [[UILabel alloc] initWithFrame:CGRectMake(100,28,80,21)];
UILabel *orderStatusMessage = [[UILabel alloc] initWithFrame:CGRectMake(200,28,80,21)];
NSString *ordertypeName = [ordertypeArray objectAtIndex:indexPath.row];
ordernum.textColor = [UIColor blackColor];
[cell.contentView addSubview:ordernum];
date.textColor = [UIColor blackColor];
[cell.contentView addSubview:date];
orderStatusMessage.textColor = [UIColor blackColor];
if ([ordertypeName isEqualToString:#"saved"]) {
ordernum.text = [NSString stringWithString:#"Saved Order"];
date.text = [NSString stringWithFormat:#"%#",sdate];
}
else{
if (![order isEqualToString:#""]) {
for (int i=0; i<[reversed count]; i++)
{
stat=[reversed objectAtIndex:i];
}
}
ordernum.text = [NSString stringWithFormat:#"%#",order];
date.text = [NSString stringWithFormat:#"%#",sdate];
orderStatusMessage.text =[NSString stringWithFormat:#"%#",stat];
[cell.contentView addSubview:orderStatusMessage];
}
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.selectionStyle = UITableViewCellSelectionStyleGray;
// }
return cell;
}
With the above code I am getting only the last item from reversed array.Please help
To start, your for loop is bogus
if (![order isEqualToString:#""]) {
for (int i=0; i<[reversed count]; i++)
{
stat=[reversed objectAtIndex:i];
}
}
Why are you looping and overwriting the reference to stat with each iteration? That's clearly not your intent.
Second, I would advise refactoring, since this code snippit is extremely confusing and it is very close to impossible to understand the intent. Please repost after renaming variables and cleaning the code a bit.
I have a table view that shows 3 data side by side in table ,lets say A(name) , B(roll no) , C(id).
Now if user do search based on A's (search by name) (table get refreshed with name while searching only) value I want to either hide the content of B & C or they should show the correct value while search is on , not the old value which they got before searching.
I couldn't find the solution how to deal with remaining B & C.kindly suggest
here is my code
- (void) searchTableView
{
NSLog(#"search button is down %#",searchBar.text);
NSString *searchText = searchBar.text;
NSMutableArray *searchArray = [[NSMutableArray alloc] init];
if(SearchQuery==1)
{
[searchArray addObjectsFromArray:[entityArray valueForKey:#"Name"]];
}
if(SearchQuery==2)
{
[searchArray addObjectsFromArray:[entityArray valueForKey:#"IC"]];
}
for (NSString *sTemp in searchArray)
{
NSLog(#"copyListOfItems in search -%#",copyListOfItems);//final array for names
NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];
if (titleResultsRange.length > 0)
[copyListOfItems addObject:sTemp];
}

Do you have the tableview delegate and datasource connected to your class?
if you are loading in this data after the view has appeared on screen check that you have reloaded the tables data source [yourTableView reloadData];
