How do I bold multiple instances of a character in an NSString?

Question

I have a string like the following :

NSString *a = @"* This is a text String \n * Followed by another text String \n * Followed by a third"

I need to print it as three lines. Now, I wanted the Asterix points in it to be bolded. So I tried :

NSMutableAttributedString *att = [[NSMutableAttributedString alloc] initWithString:a];
[att addAddtribute:NSFontAttributeName value:SOMEBOLDFONT range:[a rangeOfString:@"*"]];

But this only bolds the second and third asterix. How do I get them all bold?

As others have mentioned, you need to loop through the string to return multiple ranges. This would work:

NSString *a = @"* This is a text String \n* Followed by another text String \n* Followed by a third";
NSMutableAttributedString *att = [[NSMutableAttributedString alloc] initWithString:a];
NSRange foundRange = [a rangeOfString:@"*"];

while (foundRange.location != NSNotFound)
{
    [att addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:20.0f] range:foundRange];

    NSRange rangeToSearch;
    rangeToSearch.location = foundRange.location + foundRange.length;
    rangeToSearch.length = a.length - rangeToSearch.location;
    foundRange = [a rangeOfString:@"*" options:0 range:rangeToSearch];
}

[[self textView] setAttributedText:att];
