Compute height on control (eg.UILabel) based on text

//Compute height for label based on text

CGSize labelStringSize = [self labelStringSize:lblInput.text]; 

cell.lblInput.frame = CGRectMake(x, y, 160,labelStringSize.height);

-(CGSize)labelStringSize : (NSString *) strInput { // Detemine height based on text

    

    UILabel *tempLabel = [[UILabel alloc] init];

    tempLabel.lineBreakMode = UILineBreakModeWordWrap;

    

    tempLabel.text = [NSString stringWithFormat:@"%@",strInput];

    CGSize labelStringSize = [tempLabel.text sizeWithFont:tempLabel.font constrainedToSize:CGSizeMake(143, 9999) lineBreakMode:tempLabel.lineBreakMode];

    

    return labelStringSize;
