Count number of lines in textView

Question

I am developing an application where i need to charge the user based on the number of pages. Can anyone tell me how can i derive number of pages if the data is entered as multiline in textView. Thanx in advance

Answer 1

You can use NSString's -sizeWithFont:constrainedToSize:lineBreakMode: method to calculate the space a given amount of text would occupy.

Answer 2

thanks for the answer. This is what i have used and it worked....

-(float)getHeightByWidth:(NSString*)myString:(UIFont*)mySize:(int)myWidth

{

    CGSize boundingSize = CGSizeMake(myWidth, CGFLOAT_MAX);
    CGSize requiredSize = [myString sizeWithFont:mySize constrainedToSize:boundingSize lineBreakMode:UILineBreakModeWordWrap];  
    return requiredSize.height;
}
