Hi
I have some text field which, after a decoding, set some UILabel. The problem is that if the user leave some empty field , I don't like to see that space between the labels. I enclose a picture for a better understanding. thanks in advance.
instead of the view below use a uitableview with custom cells
Each custom cell having a label ...and add a cell if and only if u have a valid string in a textfeild..set userinteraction=NO and set some backgroung color to match ur view..
just put that string in the uilabel in the custom cell...thats it..

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 want to edit the text in a cell by tapping and I was wondering if there is a way to do it other than by adding a text field. is there something in the table view delegate that I missed?
You can create cell (or any other UIResponder subclass) that conforms UITextInput protocol (or maybe UIKeyInput is enough). Here is simple example (old link)
Notice,
you should set cell.canBecomeFirstResponder = true.
To show keyboard use cell.becomeFirstResponder()
Maybe there something else, that you should do. I recommend reading docs.
...Or use UITextField :)
We use an array to display no of text label in cell.
so you can do is, you can use a text field and a button on a view.
In button action add a line of code like stringArray[2] = "new string" to replace the particular element from array and when you enter a text and press a button the element will get replaced and just reload the table view.
And you can also write the method in didSelectRowAtIndexPath, write stringArray[indexPath.row] = "new string" and reload the table view and it is done.
Actually i used the pickerView for display My database value containing Name, SSN, Research Area etc. Now I need to search in each component of pickerview, like Name,SSN using SearchBar is it Possible?
If I understand you right, you want to filter the rows of the components when the searchtext changed.
You can have a NSArray for each component to populate it with: In – searchBar:textDidChange: you can check which entries in your arrays fit to the search text and add it to a array, that you will use to fill the picker. Don't forget to either call [aPickerView reloadAllComponents] or [aPickerView reloadComponent:i], this will tell the picker to draw itself again.
I need to format text in a label like this:
username: some text from this user. This will
create additional lines of text that will go
on and on and on.
Where "username" is bold. This will go into a UILabel, which is in a custom table cell. Is there a way to get this type of layout?
For this relatively simple case, you might be able to fake it. Have one label with the bold username, and another label with the plain text in the same position. Insert enough spaces before the plain text to leave room for the username. You can use UIStringDrawing methods to measure the bold text and the spaces.
CGSize usernameSize = [theUsername sizeWithFont:theBoldUsernameFont];
CGSize spaceSize = [#" " sizeWithFont:thePlainCommentFont];
NSString *indentedComment = [NSString stringWithFormat:#"%*s%#" , (int)ceil( usernameSize.width / spaceSize.width ) , "" , theComment];
If you use plain UILabel it's not available. Use two labels for this task.
You need to use either a UIWebView or CoreText to do this kind of advanced text layout. A web view has a lot of overhead but is most flexible and you can't use it effectively in a UITableView cell. CoreText is low level and not that well documented. You could ditch the table view and just lay out the table with CSS and HTML in the web view, which is how I do it.
You can still use a UITableViewCell but have the cell use a UIWebView subview. Set up a custom cell subclass with a clever setter method that allows you to send nsstrings to the method with turns those into a pretty formatted view.
I currently have a custom UITableViewCell which contains a few labels, and an image.
The "main" label is used to display people's names. Currently, I'm styling it in bold text.
What I'd like to do (to gain some space and readability), is to mimic the Address Book app cell style, that is: first name in light text, and family name in bold text.
Is there a way to do this using the same UILabel? Or, should I use 2 different UILabels? How should I layout them, without knowing their sizes?
Thanks in advance for your assistance!
See this sample code from atebits:

It does something similar to what you want.
You can use the built-in UITableViewCellStyleValue2. From the UITableViewCell.h header file:
UITableViewCellStyleValue2, // Right aligned label on left with blue
//text and left aligned label on right (Used in Phone/Contacts)
Pass this into your [[UITableViewCell alloc] initWithStyle:...] method.
I think it's table view cell with UITableViewCellStyleDefault style. If you'd like to use different font attributes then you need to use different labels (because there is no attributed strings yet). To calculate size of these labels you should use following method:
- (CGSize)sizeWithFont:(UIFont *)font minFontSize:(CGFloat)minFontSize actualFontSize:(CGFloat *)actualFontSize forWidth:(CGFloat)width lineBreakMode:(UILineBreakMode)lineBreakMode;
or any relevant from NSString(UIStringDrawing).
Also, you can use custom strings drawing instead of UILabel.
