Logging a particular row in didSelectRowAtIndexPath - objective-c

In the method for
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// do stuff here
}
I have a grouped table view. If I wanted Row 1 of Section 1 to spit out an NSLog, how would I do that? Also, would it be different if I wanted Row 2 of Section 3 to make a log? So far, I've only been using this method to transition between nibs.


Dirt simple:
if(indexPath.row == 1 && indexPath.section == 1) {
NSLog(#"Awesomeness");
} else if(indexPath.row == 2 && indexPath.section == 3) {
NSLog(#"Something more awesome");
}

Making a conditional for table view buttonpress

I have a table view and don't know how to access the row number when the user presses one of the cells. The data of the table view is a small array and this is the closest I could come... In the IB, I control dragged the reusable cell to the view controller I push which works fine. I am unsure how to get the row number in a conditional like this...
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// A bunch of stuff is before this, but not important to the question
//-- > This line if([indexPath row] == 1) This doesn't work... any ideas?
{
if(totalPoints < 10 && number != 0)
{
[self saveNumber:#"1"];
}
else if (totalPoints < 10 && attachment == 0)
{
[self saveData:#"1"];
int newPnts = totalPoints + 1;
[self savePoints:[NSString stringWithFormat: #"%d", newPnts]];
}
Thanks

It should work
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"%#",indexPath.row);
if(indexPath.row==1)
{
NSLog(#"Do Somthing..");
}
else
{
NSLog(#"Do Somthing..");
}
}

the row number is [indexPath row] . in tableview you have a dataSource which save the data array used to reload table

Ok I was doing something wrong elsewhere and the view controller doesn't update it's label from the saved data. I will post a seperate question if you're interested

UITableView cell's 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

Changing in Code Specific Row Heights in Objective-C

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

Question about UITableView

I have a UiTableView and the first cell is only showing information. The following cells are going to push new viewControllers to the window.
I don't want it to be possible to click on the first one, but the second cell (indexpath.row == 1) to be the first cell to click on...
Is there some property I can set to make that first cell "notChooseable"?

try:
if(indexPath.row == 0)
cell.userInteractionEnabled = NO;

- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row == 0) {
return;
}
else {
//perform pushing controllers
}
}

UITableViewCell prevent deletion

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;
}
