Question

I have a UILabel that is correctly word wrapping if I force its frame height to be tall enough. However, I want it to dynamically find the proper height, and the sizeWithFont method isn’t doing this; that method just creates a single line in my label:

CGSize subtitleSize=[subtitle sizeWithFont:subtitleFont forWidth:maxwidth lineBreakMode:UILineBreakModeWordWrap];

Then I use the same text, font and size from this function:

        UILabel *subLabel=[[[UILabel alloc] initWithFrame:CGRectMake(0, 0, maxwidth, subtitleSize.height)]autorelease];
        subLabel.font=subtitleFont;
        subLabel.text=subtitle;
        subLabel.numberOfLines=0;
        subLabel.lineBreakMode=UILineBreakModeWordWrap;

It looks like it should all work and give me a size which i then use. But the height of the size is always just one line for the label.

Answer 1

you may use this

- (CGSize)sizeWithFont:(UIFont *)font constrainedToSize:(CGSize)size lineBreakMode:(UILineBreakMode)lineBreakMode; 

max the size in constrainedToSize

CGSize size = CGSizeMake(maxwidth, CGFLOAT_MAX);
