为什么不显示NSTextAttachment图像？

Question

I'm trying to add an image to an attributed string:

NSTextAttachment *locationIcon = [[NSTextAttachment alloc] init];
locationIcon.image = [UIImage imageNamed:@"location-pin-icon"];
NSAttributedString *iconString = [NSAttributedString attributedStringWithAttachment:locationIcon];
[string appendAttributedString:iconString];
NSAttributedString *locationNameString = [[NSAttributedString alloc] initWithString:@"some text" attributes:linkAttributes];
[string appendAttributedString:locationNameString];

Then I simply set myLabel.text = string; (where myLabel is a TTTAttributedLabel )

location-pin-icon is a valid image (I've checked it in debugging too). However, the location pin icon is not being displayed in the label (the following "some text" is displayed perfectly though, and linkAttributes is just a collection of system font with a custom blue color). I've also tried manually setting bounds to the text attachment, or leaving a space before the text, but nothing seems to work.

What am I doing wrong?

Answer 1

It was apparently due to implementation of TTTAttributedLabel . The library seems broken. When I've switched from it, the attachment started displaying correctly.
