find out height of a UILabel which is size to fit

问题

I am trying to find out the height of the UILabel when the height of the UILabel changes dynamically that is when it is sizeToFit enabled. What is the way to figure out the height of the UILabel? Of course the value frame.size.height is obviously wrong when I enable sizeToFit.

Thanks.

try this it may be help you..

-(CGSize)lblSize:(NSString *)content lblFont:(UIFont *)contectLblFont width:(int)Width
{
    CGSize maximumLabelSize;
    maximumLabelSize = CGSizeMake(Width,9999);
    NSAttributedString *attributedText =
    [[NSAttributedString alloc]
     initWithString:content
     attributes:@
     {
     NSFontAttributeName:contectLblFont
     }];
    CGRect rect = [attributedText boundingRectWithSize:(CGSize){maximumLabelSize.width, CGFLOAT_MAX}
                                               options:NSStringDrawingUsesLineFragmentOrigin
                                               context:nil];
    CGSize size = rect.size;
    return size;
}

and use inside table view delegate

CGSize expectedLabelSize=[self lblSize:[NSString stringWithFormat:@"%@",[[loadMoreArray objectAtIndex:indexPath.row]valueForKey:@"text"]] lblFont:cell.self.lbldetail.font width:310];

    cell.self.lbldetail.frame=CGRectMake(5,cell.imgProfile.frame.size.height+cell.imgProfile.frame.origin.y+2, 300,expectedLabelSize.height+10);

 UILabel *detailsLabel = [[UILabel alloc]initWithFrame:CGRectMake(0,50,320,30)];
 detailsLabel.text = [textDic valueForKey:@"Text"];
 detailsLabel.textColor = [UIColor grayColor];
 detailsLabel.numberOfLines = 0;
 [detailsLabel sizeToFit];
 [scrollViewObj addSubview:detailsLabel];
 NSLog(@"Label Height %f",  detailsLabel.frame.size.height );
