Crash in iOS 7.0.3 for NSMutableAttributedString [duplicate]

问题

Since a few days, I have a crash that only happens in iOS with the following line of code

[myAttributedString addAttribute:NSFontAttributeName
                                             value:[UIFont fontWithName:@"HelveticaNeue-Italic" size:myLabel.font.pointSize]
                                             range:rangeOfSubString];

The reason given by debugger is

"Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'NSConcreteMutableAttributedString addAttribute:value:range:: nil value'" Exception Type: SIGABRT

I know from the documentation that it's the value that's nil. Any idea why [UIFont fontWithName:@"HelveticaNeue-Italic" size:myLabel.font.pointSize] would return nil in iOS 7.0.3? (it was working perfectly well in iOS 7.0.2)

回答1:

That typeface of Helvetica neue seems to be missing
