UITableView as Grid

[jaxmeier]

Hi All,

I am new to iPhone development and really enjoy it, though I have been programming with MS stuff for over 10 years. As such, I am having a hard time getting the hang of the UITableView, as I am far more fluent in using DataGrids.

What I would love to be able to do is have a master tableview, and when a record/cell is selected, pass the record ID instead of the displayed text to the detail tableview. Because my stored procs in my webservice already have lookups by ID and I am using normalized tables using ID values, I would prefer not to have to do the lookup based on the text of the record.

I already have an NSMutableArray of NSMutableDictionary items to populate the master tableview datasource with both the ID and data. I assume I would just need a custom tablecell with a hidden label or text field for the ID instead of just assigning the text to the cell.

If anyone has any alternative suggestions, I would love to hear them. I am loving this challenge and would like to continue, but the lack of a datagrid appears to me to be forcing some pretty bad habits from a developer/architect perspective...B-)

Thanks,
jax

You should be able to tell which data object you have at hand according to the cell's section/row and grab the ID from your data model, you don't need to store any data in the cell at all

I don't understand why you think that lookup based on the text of a record is needed or suggested. Cell display is based on index path (which includes row) and cell selection is also based on row. With the row number in hand, why would anybody think of looking things up based on text contents?

Now that I think about it, that makes more sense... I just got hung up in the MS datagrid model.

Thanks for setting my brain straight.

Hi Robert

I need the unique ID corresponding to the data, not the row number. I got the response above and realized I can just use the dictionary based on the array index from the row index, then pass the ID from the dictionary to the detailviewcontroller.

Thanks for the reply though
