Re: How to know the geometry of a string on the screen ?

[Josh Freeman]

   I think you meant to use 'string', not '[NSString string]' - the  
latter returns an empty string.

stringSize=[[NSString string] sizeWithAttributes:attributes];
   ->
stringSize=[string sizeWithAttributes:attributes];


   Alternatively, since string's an NSAttributedString:

stringSize=[string sizeWithAttributes:attributes];
   ->
stringSize=[string size];
