As sizeWithFont is depreciated in IOS 7.0 then you below code

#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)



 if (SYSTEM_VERSION_LESS_THAN(@"7.0")) {
        // code here for iOS 5.0,6.0 and so on
        CGSize fontSize = [itemCat_text sizeWithFont:[UIFont fontWithName:@"Helvetica" size:12]];
    } else {
        // code here for iOS 7.0
         fontSize = [itemCat_text sizeWithAttributes:
                           @{NSFontAttributeName:
                                 [UIFont fontWithName:@"Helvetica" size:12]}];
    }
