multiple line of UILabel, is it possible?

Question

I've read through SO and it seems that it is possible, however I tried it and it didn't work out:

UILabel * detailed_label = [[UILabel alloc] initWithFrame:CGRectMake(50, labelSize.height + 30, textSize.width + 5, textSize.height + 5)];
    detailed_label.backgroundColor = [UIColor clearColor];
    detailed_label.textColor = [UIColor whiteColor];
    detailed_label.font = [UIFont systemFontOfSize:12];
    detailed_label.text = self.detailed;
    detailed_label.numberOfLines = 0;
    detailed_label.lineBreakMode = UILineBreakModeWordWrap;
    detailed_label.shadowColor = [UIColor darkGrayColor];
    detailed_label.shadowOffset = CGSizeMake(1, 1);
    CGSize detailedLabelSize = [self.detailed sizeWithFont:label.font constrainedToSize:CGSizeMake(280.0f, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];


    UIButton *v = [UIButton buttonWithType:UIButtonTypeCustom];
    v.frame = CGRectMake(0, 0, textSize.width + avatar_image.size.width + 10, labelSize.height + detailedLabelSize.height + 30);
    //label.center = CGPointMake(v.frame.size.width / 2, v.frame.size.height / 2);
    [v addSubview:detailed_label];

Am I doing something wrong?

I had a look at your code and you're assigning a width at the UILabel which is textSize.width+5. Is this textSize.width related to the UILabel text? — Francesco Puglisi, May 25 '11 at 22:18

Can you try a bigger height to label ? For example, 2*textSize.height. — AechoLiu, May 26 '11 at 00:27

As your working with a UIButton. You can take advantage of the label already on it, use button.titleLabel to access it.

Next set button.titleLabel.minimumFontSize and button.titleLabel.font. Then set button.titleLabel.numberOfLines > 1.

If you need to find out how high to make your label. Use [self.detailed sizeWithFont:fontWithMinimumFontSize constrainedToSize:CGSizeMake(width, DBL_MAX) lineBreakMode:UILineBreakModeWordWrap].height + PADDING;
