UITableview Cell height not working in IOS7

Question

My problem is similar to this SO question. my UITableViewCell Height perfect working on IOS8. Problem With IOS7 hight is increase but content is not display.

my code is:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
long hightmain=0;

    if(selectIndex && indexPath.section == selectIndex.section)
    {

        NSString * myString = [description_vegetable_array objectAtIndex:indexPath.section];
        CGSize labelSize = [myString sizeWithFont:[UIFont systemFontOfSize:15]  constrainedToSize:CGSizeMake(190, MAXFLOAT) lineBreakMode:NSLineBreakByWordWrapping];
        hightmain=labelSize.height+120;

        if (hightmain<=140)
        {
             btn11.frame=CGRectMake(240,100,70,17);
             Description_LBL.frame=CGRectMake(127, 0, 190, 140);
             BGImage.frame=CGRectMake(0, -3, 320, 140);
        }
        else
        {                               
            [btn11 setTitle:@"Less Info" forState:UIControlStateNormal];
            btn11.frame=CGRectMake(240,hightmain-30,70,17);
            Description_LBL.frame=CGRectMake(127, -20, 190, hightmain);
            BGImage.frame=CGRectMake(0, -3, 320, hightmain);
            return hightmain;
        }
    }
    else
    {
        return 140;
    }
}

Description_LBL.frame=CGRectMake(127, 0, 190, 140); my label height increases but text not display ....in IOS8 complete working but IOS7 in not working

I'm not sure if this has to do with your problem but sizeWithFont:constrainedToSize:lineBreakMode: is deprecated since iOS7, be careful — Leonardo, Feb 03 '15 at 11:54
Are you reloading the tableView when selecting a row?, heightForRowAtIndexPath get called only on populating the table or scrolling through the table. — Fantini, Feb 03 '15 at 12:00
@JayBhalani Can you just try to print the hightmain inside and check whether the problem is showing up for certain height[iOS7].also one more thing if (hightmain<=140) in that case you are still not returning anything[may not be the reason] — Jacob Davis Cherussery, Feb 03 '15 at 12:31

Use boundingRectWithSize: which NSString public methods that calculate the size based on a string value.

Example

[testString boundingRectWithSize:CGSizeMake([UIScreen mainScreen].bounds.size.width,MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:15]} context:nil]

Note: sizeWithFont: Deprecated in iOS 7.0
