I have a UITableView that uses prototype cells to recreate a table. I have the first row with height 30 and the rest default 44. I would like to change only first row's height but have failed to do so. I tried cellForRowAtIndexPath but I learned here that it's heightForRowAtIndexPath: I'm interested in. However, all the IndexPath's that get sent to it are [0,0]. Can anyone help?
Have you tried this?
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row == 0) { //first row
return 30;
}
else {
return 44;
}
}
Do this for resizing the cells in your table views delegate.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == 0)
return 30.0;
return 44.0;
}
If this doesn't work: give us your code

EDIT
My constraints on custom cells are all weird. Please disregard. Just using standard Left Detail ones now.
I don't understand why in iOS8 now my static table view cell contents are collapsing into the header of each section.
There's really almost nothing in my SettingsTVC.m. This is a just a test with all static data in the storyboard:
- (void)viewDidLoad {
[super viewDidLoad];
}
Have you implemented TableView delegate methods properly i.e
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
if(section == CUSTOM_SECTION)
{
return CUSTOM_VALUE;
}
return UITableViewAutomaticDimension;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return height;
}
I have a simple question, not able to sort it out. I have a UITableView in my application. There are 3 section and each section has 3 rows.
I want to increase the height of first cell of the first section. I am using the delegate for this but it increases the height of the first cell of the third section.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == 0 && sectionValue==0)
{
sectionValue=1;
return 180.0;
}
else
{
return 44.0;
}
}
You can directly use indexPath.section -
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == 0 && indexPath.section==0)
{
return 180.0;
}
else
{
return 44.0;
}
}
try this......
indexPath.section
I have three different custom cells of different heights. How should I use,
heightForRowAtIndexPath
To set the specific cell's height up. Something allong the lines of this.
if ([CellIdentifier isEqualToString:#"Cell"]) {
return 200;}
No avail
copy the code that figures out what cell to use from cellForRowAtIndexPath: to heightForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cel;
NSString *CellIdentifier;
// whatever code you use to figure out what cell to use
if ([CellIdentifier isEqualToString:#"Cell"]) {
// create & configure "Cell"-cell
}
else {
// configure Standard cell
}
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier;
// whatever code you use to figure out what cell to use
if ([CellIdentifier isEqualToString:#"Cell"]) {
return 200.0f;
}
else {
return 44.0f;
}
}
Would you guyz be so kind to help me with such question:
I have to fill the tableView with cells and I also have an array with objects to fill cells with.
The question is - how to skip creating a cell if the object doesn't meet some conditions? I mean how to write something like:
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if(objectIsOk) {
//create cell
}
else {
//do nothing
}
return cell;
NOTE: I don't have an access to that array of objects it gives me an object per indexPath.row dynamically
I'm unsure as to what you mean by "skip creating a cell". Your table view data source is required to return a cell for each cellForRowAtIndexPath: call, which will get called for each row in each section that you have said the table will contain.
If you want to return a blank cell then why not just do something like this:
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
if (objectIsOk) {
// Create normal cell
} else {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"BlankCell"];
}
return cell;
}
You could also return height of zero in the heightForRowAtIndexPath: delegate method to make it appear that it's not there, like so:
- (CGFloat)tableView:(UITableView *)aTableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (objectIsOk) {
return 44.0f;
} else {
return 0.0f;
}
}
I am looking for a way of preventing the deleting of one of my cells. (No delete button should appear next to the cell when the table view is in editing mode.)
How can this be made possible?
Implement editingStyleForRowAtIndexPath and return UITableViewCellEditingStyleNone for that row:
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.section == sss && indexPath.row == rrr)
return UITableViewCellEditingStyleNone;
else
return UITableViewCellEditingStyleDelete;
}
The accepted response works but is not the correct way to do it. There are two methods available: editingStyleForRowAtIndexPath and canEditRowAtIndexPath
editingStyleForRowAtIndexPath: Use when there are multiple different editing styles in the table
canEditRowAtIndexPath: Use when some rows should edit and some should not.
Therefore the correct way to implement your table delegate is:
- (BOOL)tableView:(UITableView *)tableView
canEditRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.section == sss && indexPath.row == rrr)
{
return NO;
}
return YES;
}
