UITableViewCellAccessoryDetailDisclosureButton not shown in cell - iphone

I am using tableView grouped Style. my DisclosureButton is not shown in my table cell.what I am missing?
THANKS
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *SimpleTableIdentifier = #"SimpleTableIdentifier";
NSArray *listData =[self.tableContents objectForKey:[self.sortedKeys objectAtIndex:[indexPath section]]];
UITableViewCell * cell = [tableView
dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
if(cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier] autorelease];
}
NSUInteger row = [indexPath row];
cell.textLabel.text = [listData objectAtIndex:row];
// cell.backgroundColor=[UIColor brownColor];
cell.accessoryType =UITableViewCellAccessoryDetailDisclosureButton;
return cell;
}

Your table seems to be in editing state. You should set the accessoryType in editing mode.
cell.editingAccessoryType=UITableViewCellAccessoryDetailDisclosureButton;

UITableView hide the accessory button in editing mode.
So if you want to display it, you will need to customize the UITableViewCell.
Or you can do it like the answer given by

xcode changinging the color of text tableview for each line

can i change the text color for each line in 1 cell, i know i can make it using custom cells, but i want to know if its possible to do it without making custom cells
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"CustomCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = [array objectAtIndex:indexPath.row];
cell.textLabel.font = [UIFont systemFontOfSize:18];
cell.textLabel.numberOfLines = 3;
return cell;
}
you could do a modulo 2 on the indexPath and check if its 0. if it is, use one color, if not use another as background for example. This way you color every second cell if that is what you intent

TalbeView cell showing null value

I have created a custom table for the rootViewController of a split view application so that the selected row expands and shows as a sub-table (showing main menu and sub menu ). The first row of the sub-table should show the particular main menu item of the sub-table.I'm fetching the main menu items from another class.
The problem is that the first row for the sub table is showing blank for me.Using NSLog, I checked the value of variable just before assigning it to the cell and even after assigning the value to the cell, i checked the text value in the cell using cell.textLabel.text. I'm getting the value in the console every time, but the row is still blank!!!
Row is showing the value if I'm hard coding it with any value!!!
Note:TableView is showing values for remaining rows.
Anybody can help me?? Thanks in advance...and sorry for my poor English..
EDIT: In the rootViewController:
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
tableView.separatorColor=[UIColor grayColor];
if (sectionopen[indexPath.row]) {
accordianTable *cell1;
cell1=(accordianTable *)[tableView dequeueReusableCellWithIdentifier:#"cell1"];
if (cell1 == nil) {
cell1 = [[[accordianTable alloc] initWithFrame:CGRectZero reuseIdentifier:#"cell1"] autorelease];
}
cell1.selectionStyle=UITableViewCellSelectionStyleNone;
return cell1;
} else {
//tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
static NSString *CellIdentifier = #"CellIdentifier";
// Dequeue or create a cell of the appropriate type.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.selectionStyle = UITableViewCellSelectionStyleGray;
}
// Configure the cell.
cell.textLabel.text=[UIAppDelegate.mainMenu objectAtIndex:indexPath.row];
return cell;
}
}
(void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
accordianTable *acc = [[accordianTable alloc]init];
acc.titl=[UIAppDelegate.mainMenu objectAtIndex:indexPath.row];
[acc.subTable reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationFade];
///turn them all off
sectionopen[0]=NO;
sectionopen[1]=NO;
sectionopen[2]=NO;
sectionopen[3]=NO;
///open this one
sectionopen[indexPath.row]=YES;
///animate the opening and expand the row
[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationFade];
UIViewController *localdetailViewController = nil;
}
In the custom cell class (accordianTable):
(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Number of rows is the number of time zones in the region for the specified section.
return [UIAppDelegate.subMenu count]+1;//including title and sub menu
}
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = #"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease];
}
switch (indexPath.row)
{
case 0:
NSLog(#"text is >> %#",titl);
cell.textLabel.text=titl;
NSLog(#"text is >> %#",cell.textLabel.text);
cell.textLabel.textColor=[UIColor whiteColor];
cell.contentView.backgroundColor=[UIColor blackColor];
cell.textLabel.backgroundColor=[UIColor blackColor];
cell.selectionStyle=UITableViewCellSelectionStyleNone;
break;
default:
int Row=indexPath.row;
Row--;
cell.textLabel.text=[UIAppDelegate.subMenu objectAtIndex:Row];
cell.textLabel.textColor=[UIColor orangeColor];
cell.textLabel.textAlignment=UITextAlignmentCenter;
cell.selectionStyle=UITableViewCellSelectionStyleNone;
break;
}
return cell;
}

UITableView backgroundview not working on text area

I'm trying to customize how my UITableView looks by setting the backgroundView with an UIImageView, but is not working properly as you can see in the image. (only works for the accessoryType and at the start of the row before the text.)
Can anybody help me with this?
My code:
// Customize the appearance of table view cells.
- (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.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
// Configure the cell.
NSDictionary *lineaAutobus = [buscamionService objectAtIndex:indexPath.row];
NSString *lineaAutobusNombre = [lineaAutobus objectForKey:#"nombre_lineaAutobus"];
[cell setBackgroundView:[[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"tableViewCellBg.png"]] autorelease]];
cell.textLabel.text = lineaAutobusNombre;
return cell;
}

Perhaps you need to set the backgroundColor of the textLabel to [UIColor clearColor]?

UITableView cell text not showing?

I'm not seeing the text for my UITableView show up.. in fact the TableView doesn't appear to be on the screen at all because I cannot select the empty rows.
Strangely, my log in cellForRowAtIndexPath shows up ok with the expected data - I just don't see any on the screen.
-(void)bindFriendsToTable:(NSArray *)friends{
NSLog(#"friends : %#",friends);
[sections removeAllObjects];
[sectionRows removeAllObjects];
[sections addObject:#"Friends"];
[sectionRows setObject:friends forKey:#"Friends"];
[self.tableView reloadData];
HideActivityIndicator();
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellsection = [sections objectAtIndex:indexPath.section];
NSArray *rowsInSection = [sectionRows valueForKey:cellsection];
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.font = [UIFont fontWithName:#"Helvetica" size:14];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
cell.textLabel.text = [rowsInSection objectAtIndex:indexPath.row];
NSLog(#"%#",cell.textLabel.text);
return cell;
}
I'm inheriting from a base class which is a UITableViewController, as I have for a dozen other screens in the project. Any idea why I'm not seeing the tableView?
Is your font colour the same as your background colour? If you set the accessoryType to a checkmark does it display?
cell.accessoryType = UITableViewCellAccessoryCheckmark;
Do you have any header sections? If so make sure you return a value for heightForHeaderInSection:
-(float)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{
return 66;
}
i think u should remove
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
and then try it.
and display the other static string in the cell to check the problem.

App crashes at cellForRowAtIndexPath

My app crashes when I scroll the UITableView over the first cell or the last cell!
Why this is happening? I add with addObject:name the objects of the UItableview . This is the code I use at cellForRowAtIndexPath. Help please! I have been trying to figure out what is going wrong hours!
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString * DisclosureButtonCellIdentifier =
#"DisclosureButtonCellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
DisclosureButtonCellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier: DisclosureButtonCellIdentifier]
autorelease];
}
NSUInteger row = [indexPath row];
NSString *rowString =nil;
rowString = [list objectAtIndex:row];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
[rowString release];
return cell;
You are calling [rowString release]; but you never retained it.
Is it throwing an exception - my guess is the index is not set:
rowString = [list objectAtIndex:row];
Can you set a breakpoint on this line and dump the "list"?
