Question

I use buttons to display letters in a bar now this is the code I use

-(IBAction) clicked: (id)sender{
NSString *titleOfButton = [sender titleForState:UIControlStateNormal];
NSString *newLabelText = titleOfButton;
labelsText.text = [NSString stringWithFormat:@"%@%@", labelsText.text, newLabelText];

 //if ([newLabelText length] >= 5) newLabelText = [newLabelText substringToIndex:5];
 }

The problem I got is that I want it to be able to put in 5 letters max Is there anyone who can tell me how to do this?

thanks

Add this line –

if ([newLabelText length] >= 5) newLabelText = [newLabelText substringToIndex:5];

…or apply the same to whatever string you want to truncate.
