sizeWithFont does not get marked as deprecated when working with array, it is safe then?

Question

If I write it as follows no deprecation alert shows up:

NSArray *aboutInfo=[NSArray arrayWithObject:@"blah"];
CGSize textSize = [[aboutInfo objectAtIndex:0] sizeWithFont:[UIFont systemFontOfSize: 14.0] constrainedToSize:wSz2xh lineBreakMode:NSLineBreakByWordWrapping ];

However this is marked as deprecated:

NSString *aboutInfo=@"blah";
CGSize textSize = [aboutInfo sizeWithFont:[UIFont systemFontOfSize: 14.0] constrainedToSize:wSz2xh lineBreakMode:NSLineBreakByWordWrapping ];

Both work fine.

Would that mean that 1st code is safe?

I use XCode 6.2, app's project and targets deployment target is iOS7.1

Answer 1

I would assume XCode doesn't mark the first one as deprecated because it can't be sure the first receiver really is an NSString. The method you are talking about is deprecated nonetheless.
