iOS UITableView cellForRowAtIndexPath Not Calling

Question

It's UITableView numberOfRowsInSection not calling. but cellForRowAtIndexPath is not being called. I don't understand why cellForRowAtIndexPath is not called. if i retun number of row in section

 return (allOfficedata.count >0)? allOfficedata.count + 1 : allOfficedata.count; 

or

return [array count]+1;  
 if (allOfficedata.count >0) return [allOfficedata count] + 1;

is not calling cellforrowatindexpath, If i give return Array count; or return 11; its working fine Belove i attached my code, Error

***** Terminating app due to uncaught exception 'NSRangeException', reason: '* -[__NSArrayM objectAtIndex:]: index 10 beyond bounds [0 .. 9]'

Answer 1

The most likely reason for cellForRowAtIndexPath never being called, other than the row count being wrong, is that the table view thinks there are no rows to display.

cellForRowAtIndexPath will only be called when a cell is needed. You seem to have cells with very large heights looking at your code. Could not see any code for section header view or height.

So given the large heights, especially for row 0 it seems (300 or 400 according to your code), there are not going to be many calls to this function unless you scroll up. As you scroll you should see more calls for cells.

Also check if you return 0 for the height, as that could also stop it trying to show the cell I think as its not going to be seen.

It will ask for the height of each row to estimate the scroll bar size needed.

Answer 2

So your saying allOfficedata + 1 for numberOfRowsInSection but in heightForRowAtIndexPath: you have the following line:

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

This causes your crash on the last cell, so you want to check is it the last cell and if it is do something else.

Edit:

As well as that you seem to be doing a similar thing in cellForIndexPath,

you do something if (indexPath == 0) but after that for the next cell you get:

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

you should - 1 from the indexPath.row, as currently your get for the cell at, lets say indexPath.row == 1, your asking for the object at index 1 where, I think you should ask for 0. AS it stands when you get to the last cell the app will crash on the above line.

Edit 2:

So the problem is your asking allOfficedata for an index that is not there, when you say allOfficedata+1 for the rows and when it gets to the heightForRowAtIndexPath for the last cell in the table it asks for the data out of allOfficedata for index that is not there, because its looking for the +1 you gave in numberOfRowsInSection

So lets say the count of allOfficedata is 10 (index 0-9) and we've said the number of rows in the table is allOfficedata+1, so its 11 (index 0-10).

Now in heightForRowAtIndexPath we get to last cell(index 10), allOfficedata doesn't have it because its index is 0-9. you ask allOfficedata for index 10 it will crash.

Answer 3

NSArray goes out of bounds..

• 10 values in array 0 to 9 [not 1 to 10]
• In table index is also the same 0 to 9 [ not 1 to 10]

so indexpath.row will give you the correct value for determining value from array at the right position
