I have a UITableView that has about 20 cells. Each has a UILabel within, and I need to search and find the cell that has the label #"Test".
Is there a way to loop through the cells and search for the NSString #"Test"?
No. You should not inspect the table view cells. Instead you should look in your data source that is providing the contents of those labels.

Setting up the UILabel on the attributes inspector as follow expands the cell and display the large text as multiple lines correctly for a Subtitle tableview cell:
Lines = 0
Line Break = Word wrap
But this doesn't work in a custom tableview cell for some reasons. In the custom cell, I added new labels and setup the attributes the same way but the cell doesn't expand.
It could be a matter of constraint.
Check to see if there are any conflicting constraints or fixed settings.
In order for elements of a cell to be set flexibly, the height of the cell must be set to the automatic value.
When I set it up like this, I was able to get the results I wanted.
I have a custom separator style (fairly simple):
[[UITableView appearance] setSeparatorColor:SOMECOLOR];
Now I want to have my tableview finish with a separator. Currently separators only appear between two cells, but I want to have a separator at the end.
see here:
any ideas how this could be done?
I usually make my own separator inside the table view cell. I do this with a UIView that spans the width of the cell and is 1 or 2 points high.
In your case, if you want the system separator, you would have to add a custom cell at the end which is all transparent and 1 point high. UITableView would then add the missing separator.
I understand it you want a separator at the end as well? You can add a footer view to achieve this effect.
Make a footer view with height of 0.0001. To do so simply implement the following tableview delegate method :
-(CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section{
return 0.001;
}
do I need separate UILabel in a custom UIView to have separate UILabel lines in a UITableViewCell?
That is, if I want to have a TableViewCell that has all text, but the text needs to contain 4 separate rows for 4 separate strings (e.g. Name, Title, Description, Location), and each these separate rows could include a wrap around.
To ask the question the other way around, is there way with a normal UITableViewCell using it content view and single text label, to force Carriage Return/New Line points at the end of each of the four strings? Oh yes, and the cell height will need to be calculated for each Cell as it may vary (just in case this is significant)
The answer to the last question: NO. (Answer to the title: YES.)
You can build a cell in its own NIB file. An exercise I suggest if you've never done it.
Layout the size/location/resize functionality as you like it.
your table view controller can be the owner of the file,
add an outlet to the TV controller of loadedCell, and call load nib
every time you want to alloc a new cell,
i suggest tagging each of the cell labels, and accessing them
that way, and setting the loadedCell value to nil after loading it,
p.s. a UILabel often wraps text undesirably, or is hard to layout in a cell to look good, consider the other values of lineBreakMode for your labels
p.p.s. it will employ a text shortening behavior depending on adjustsFontSizeToFitWidth and minimumFontSize (taking this and lineBreakMode into consideration)
Im trying to create a table very similar to the Messages table,
It requires 3 labels,
- Title
- detailText
- Time (on the far right side)
The detail text needs to be dynamic height and so does the actual tableViewCell
is it possible to make a dynamic height tableViewCell in IB?
Yes you can,
Just use this method to of the UITableViewDelegate
tableView:heightForRowAtIndexPath:
First, you need some NSString method to calculate the height of cell it needs. And in my experience, you need the tableView:heightForRowAtIndexPath as Cyprian said, and under different cell height, the cell returned from tableView:cellForRowAtIndexPath: should have different layout too, to present the multi-line strings.
i have done like
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 3;
}
tableview is in UITableViewStylePlain.but it shows correctly 3 data on 3 tableview cell.but after that there is empty tableview cells ...but when i declared UITableViewStyleGrouped, it shows only 3 tableview cells... perfectly...what i have to do disappear empty tableview cell
in UITableViewStylePlain..any help pls?
Your table contains 3 table cells and those cells beneath it are not empty table cells. The row seperators are just drawn based on the previous row height giving the impression that there are more cells than you actually specified.
You could set the separatorStyle of the table view to UITableViewCellSeparatorStyleNone, either in code or in Interface Builder. But doing so disables the seperators all together, so you would have to draw some kind of separator yourself in your cells if you still wanted a grafical separation between the actual cells.
Another option would be to set the color of the separator to the color of the background of the table.
I myself would not worry about this if you're application has a standard table look, as it's default behaviour & users should be used to seeing that. Altough I must admit that I have set the separatorStyle to none in a previous project, because the table had a look that deviated from the standard table look. I did have to draw a fine separator line at the bottom in the table cell.
