vijayeta,
The idea is to create a CGSize that's as wide as your text field, but very tall. Then you call the NSString method -sizeWithFont and ask the string how tall it would be at the specified font and field width. To calculate cell height you then need to add the origin.y of the text field, plus any space you need below the text field, to get the final cell height.
Here's a snippet of the code I use in my heightForRowAtIndexPath method:
Code:
CGSize tempSize;
CGSize theTextSize;
tempSize.width = theTableWidth-(10+ 7 + kImageSize);
tempSize.height = 9999;
theTextSize = [theText sizeWithFont: theFont constrainedToSize: tempSize];
