Question

I do this to make my UIlabel, setting the numberOfLines to 0 so that it has no line-limit:

    UILabel *nmLbl = [[UILabel alloc] initWithFrame:CGRectZero];
    [nmLbl setFont:[UIFont boldSystemFontOfSize:16.0f]];
    [nmLbl setNumberOfLines:0];
    [self addSubview:nmLbl];
    [nmLbl release];

Later on, when I know which string goes into the label, I size it like this:

    nameSize = [[self name] sizeWithFont:[UIFont boldSystemFontOfSize:16.0f] constrainedToSize:maxNameSize lineBreakMode:UILineBreakModeWordWrap];
    [self.nameLabel setFrame:CGRectMake(0.0f, 0.0f, nameSize.width, nameSize.height)];
    [self.nameLabel sizeToFit];

Now, for my particular use, I need to know how many lines this ends up taking.

If I access the numberOfLines property of the UILabel it will always return 0.

Is there a way for me to directly access how many lines the UILabel ended up being without
having to calculate it, again, by going label.size.height / fontHeight?

Thank you in advance.

No. numberOfLines is a configuration setting, not a reflection of the current formatting.
