Question

How can I draw a NSString centered within a NSRect?

I’ve started off with: (an extract from the drawRect method of my custom view)

NSString* theString = ... [theString drawInRect:theRect withAttributes:0]; [theString release]; 

Now I’m assuming I need to set up some attributes. I’ve had a look through Apple’s Cocoa documentation, but it’s a bit overwhelming and can’t find anything for how to add paragraph styles to the attributes.

Also, I can only find horizontal alignment, what about vertical alignment?

Answer 1

Vertical alignment you’ll have to do yourself ((height of view + height of string)/2). Horizontal alignment you can do with:

NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy]; style.alignment = NSTextAlignmentCenter; NSDictionary *attr = [NSDictionary dictionaryWithObject:style forKey:NSParagraphStyleAttributeName]; [myString drawInRect:someRect withAttributes:attr];
