You can’t.
let s : NSString = "hallo\there"
let aas = NSMutableAttributedString( string: s, attributes: nil
)
let rangeOfTab = s.rangeOfString( "\t" )
if rangeOfTab.location != NSNotFound
{
let colour = UIColor.grayColor()
let aRange = NSRange(location:0,
length:rangeOfTab.location )
aas.addAttribute( NSForegroundColorAttributeName,
value: colour, range: aRange )
} }
After 1+ months are you sure Swift is worth all this effort?
