Add attributed text hides UILabel

Question

I'm trying to add a strikethrough to some of my labels. My project supports 32 and 64 bit. Everything works great on iOS 8, but on iOS 7 on iPhone 5c the label just disappear. Here's my code:

NSMutableAttributedString *throughLineAttributeString = [[NSMutableAttributedString alloc] initWithString:label.text];
    [throughLineAttributeString addAttribute:NSStrikethroughStyleAttributeName
                                       value:@1
                                       range:NSMakeRange(0, [throughLineAttributeString length])];
label.attributedText = throughLineAttributeString;

What am I doing wrong?

add label.layer.borderWidth = 3; and check, is it gone away or it just shows nothing — mityaika07, Dec 03 '14 at 11:50
Yes the label is still there with the same frame. Seems like just the text is missing. — YogevSitton, Dec 03 '14 at 12:34
ok, set label.layer.masksToBounds = NO, and check the text position — mityaika07, Dec 03 '14 at 12:36
with this line the text will be rendered outside of labels frame to — mityaika07, Dec 03 '14 at 12:59
Only on iPhone 5C with iOS7 with specific labels (for other labels it works) — YogevSitton, Dec 03 '14 at 13:30
As far as I rememeber iOS 7 had issues with underlined texts, I had to render it manually once. There are nice components like THLabel that take care of this for you. Besides, you might like to set color for your text because it can be simply invisible and match your background. — pronebird, Dec 03 '14 at 13:53

Try to change:

NSMutableAttributedString *throughLineAttributeString = [[NSMutableAttributedString alloc] initWithString:label.text];

to:

NSMutableAttributedString *throughLineAttributeString = [[NSMutableAttributedString alloc] initWithAttributedString:label.attributedText];

The label doesn't have an attributedText at this point. It has only text. – YogevSitton Dec 03 '14 at 13:16
