how to place star rating image next to the textlabel - iphone

Question

i m parsing json feed and according to the parsed value i m placing star images in table view cell.what i want is to place the star rating images as soon as the no of words in the textlabel gets completed the star rating images got to be flexible and not to have fixed frame. below is the code and screenshot of how the output got to look like.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//[tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
static NSString *CellIdentifier = #"Cell";
HJManagedImageV* mi;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
mi = [[[HJManagedImageV alloc] initWithFrame:CGRectMake(-18,-2,90,90)] autorelease];
mi.tag = 999;
[cell addSubview:mi];
}
else
{
mi=(HJManagedImageV *)[cell viewWithTag:999];
[mi clear];
}

You can use the following method to calculate the width and height of a string --
– sizeWithFont:
– sizeWithFont:forWidth:lineBreakMode:
– sizeWithFont:constrainedToSize:
– sizeWithFont:constrainedToSize:lineBreakMode:
– sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode:
or you can refer the doc here https://developer.apple.com/library/ios/#documentation/UIKit/Reference/NSString_UIKit_Additions/Reference/Reference.html
on the basis of width you need to set your label width and then set the frame of your star image.
an example -
CGSize sizeTitle = [titleStr sizeWithFont:[UIFont boldSystemFontOfSize:16.0]
                                      constrainedToSize:CGSizeMake(200, 40)
                                          lineBreakMode:UILineBreakModeWordWrap];
float width = sizeTitle.width;
