Я сделал это, создав category
для NSMutableAttributedString
-(void)setColorForText:(NSString*) textToFind withColor:(UIColor*) color
{
NSRange range = [self.mutableString rangeOfString:textToFind options:NSCaseInsensitiveSearch];
if (range.location != NSNotFound) {
[self addAttribute:NSForegroundColorAttributeName value:color range:range];
}
}
Используйте это как
- (void) setColoredLabel
{
NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:@"Here is a red blue and green text"];
[string setColorForText:@"red" withColor:[UIColor redColor]];
[string setColorForText:@"blue" withColor:[UIColor blueColor]];
[string setColorForText:@"green" withColor:[UIColor greenColor]];
mylabel.attributedText = string;
}

extension NSMutableAttributedString{
func setColorForText(_ textToFind: String, with color: UIColor) {
let range = self.mutableString.range(of: textToFind, options: .caseInsensitive)
if range.location != NSNotFound {
addAttribute(NSForegroundColorAttributeName, value: color, range: range)
}
}
}

SWIFT 4 @ kj13 Спасибо за уведомление
// If no text is send, then the style will be applied to full text
func setColorForText(_ textToFind: String?, with color: UIColor) {
let range:NSRange?
if let text = textToFind{
range = self.mutableString.range(of: text, options: .caseInsensitive)
}else{
range = NSMakeRange(0, self.length)
}
if range!.location != NSNotFound {
addAttribute(NSAttributedStringKey.foregroundColor, value: color, range: range!)
}
}
Я провел больше экспериментов с атрибутами, и ниже приведены результаты, вот ИСТОЧНИК
Вот результат
