Updating a label in a cell

[keano]

Hello,

I will like to update a particular label in all the table cells (using an array) whenever the user taps the return button on the keyboard.

I have already created a setLabel(NSString *) method in the table cell class. However, I can’t seem to call this method from the textFieldShouldReturn method (when the user taps the return key).

I also tried to call the cellForRowAtIndexPath method in the textFieldShould Return method using the following lines:

For LOOP
cell1 = [[self tableView] cellForRowAtIndexPath: counter]

However, the application always hangs because an exception is thrown.

Will appreciate any help, thank you =)

[tableView reloadData];
that will call cellforrow and any others that the tableview uses to set its cells/rows/sections

Hi,

Thank you for your quick reply.

What I will like to do is to update a particular label in all the table cells using a new array of data. If I am to reload the data, how do I tell the cell that I have a new set of data for the label?

*Hope I am making sense here, it is all quite new to me, thank you again =)

Hello,

Your question actually created the idea that I could just change the value in the array and then reload the data.

I have tried it and it worked.

Just want to say a sincere thanks because it is a problem that I have been stuck in for some time (Yes, I am quite a noob
