TTT attributed Label Multi- colored Font help

Question

-(UITableViewCell*) makeLikeCell
 {
    // Load the top-level objects from the custom cell XIB.
NSArray *topLevelObjects = [[NSBundle mainBundle]      loadNibNamed:@"SpotlightLikesTableViewCell" owner: self options: nil];

// Grab a pointer to the first object (presumably the custom cell, as that's all the XIB should contain).
UITableViewCell *cell = [topLevelObjects objectAtIndex:0];


NSString *likeText = [likesAndComments objectAtIndex: kLikeRow];

TTTAttributedLabel *likeLabel = [[[TTTAttributedLabel alloc] initWithFrame:CGRectZero] autorelease];
likeLabel = (TTTAttributedLabel*) [cell viewWithTag: kCaptionTag];
likeLabel.textColor = [UIColor blueColor];
likeLabel.lineBreakMode = UILineBreakModeWordWrap;
[likeLabel setFont: [UIFont fontWithName: @"Helvetica Neue" size: 10]];

[likeLabel setText: likeText afterInheritingLabelAttributesAndConfiguringWithBlock: ^NSAttributedString *(NSMutableAttributedString *mutableAttributedString) {
    NSRange colorRange = [[mutableAttributedString string] rangeOfString: @" like this photo." options: NSCaseInsensitiveSearch];

    [mutableAttributedString addAttribute:(NSString *) kCTForegroundColorAttributeName value:(id)[[UIColor grayColor] CGColor] range:colorRange];
    return mutableAttributedString; }];

return cell;
}

I added the TTT attributed label to my project. I want to have 2 different font colors to display the "likes". However my project keeps crashing. A sample string to be formatted would be: "andrew, john, amos likes this photo."

any suggestions? enter image description here

Could you be more specific in what the console spits out when it crashes? If you run with breakpoints on, can you do `bt` to get a backtrace after it crashes? My first thought was that you might be running into problems by passing `colorRange` into `-addAttribute:value:range` without checking if the string wasn't found (`colorRange.location == NSNotFound`) — mattt, Jun 02 '11 at 21:11

Use like this

[likeLabel setText:likeText afterInheritingLabelAttributesAndConfiguringWithBlock: ^(NSMutableAttributedString *mutableAttributedString) {
    NSRange colorRange = [likeText rangeOfString: @"like this photo." options: NSCaseInsensitiveSearch];
    if (colorRange.location != NSNotFound) {
        [mutableAttributedString addAttribute:(NSString *) kCTForegroundColorAttributeName value:(id)[[UIColor grayColor] CGColor] range:colorRange];
    }
    return mutableAttributedString; 
}];

There is a way to set different / multiple fonts & other properties like color on Label using NSMutableAttributedStrin. Refer to my answer on Multiple Font & Color for string & Display the string on Label
