dynamically displaying table cells height with boundRectWIthSize

Question

Right now, I'm using the following code to display my table cell. It is displaying text properly. However, there are some texts which are too long, so I want to display the first 5 lines of the text and then if the user expands the cell, it will display the whole text. I'm stuck because I am not so familiar with the new method in ios 7, boundRectWithSize.

CGSize size = CGSizeMake(self.reviewComments.width,999);
CGSize textRect =[self.reviewComments.text boundingRectWithSize: size options: NSStringDrawingUsesLineFragmentOrigin
                                                     attributes: @{NSFontAttributeName:self.reviewComments.font} context: nil].size ;


float height = textRect.height;
self.reviewComments.height = height;

I tried:

if (height > 150) {
    height = 150;
}

But this way just cuts off the text, even after when I expand it.

UPDATE/EDIT:

I want my cell so that it only displays maybe the first 5 lines of the text if it exceeds 5 lines. The entire text will appear if the cell is expanded.

What's wrong with the first method? What results does it give you? — rdelmar, Apr 09 '14 at 04:53

Try this:

float height = ceilf(textRect.height);

sorry, I've implemented this line. It still does the same thing. I don't understand how this sets a limit for the number of lines. – user3513175 Apr 09 '14 at 18:55
