NSTextView not drawing text onto NSImage - objective-c

Question

I'm attempting to draw some text onto an NSImage, but I've run into some issues.
Originally I was just drawing an attributed string onto the NSImage, but if the string was too long it would run off the image and I couldn't find a way to wrap the text to a newline.
To solve this I figured that I could just make an NSTextView, place the text in there, and then draw it onto the NSImage.
Unfortunately, when I attempt to draw the NSTextView to the NSImage, the text does not appear. The NSTextView's background color does show up though.
When I set a breakpoint before I lock focus on the NSImage, and preview the NSTextView, the text view has text. After I draw the text view onto the NSImage, it looks like the NSTextView is drawn, just without the text.
If there is a better way to throw text onto an NSImage that has the ability to have multiple lines, please let me know how.
Here's the code I've written for reference:
NSTextView *textToDraw = [[NSTextView alloc] initWithFrame:NSMakeRect(0, 0, input.size.width - 16, 243)];
textToDraw.backgroundColor = [NSColor blueColor];
[textToDraw setAlignment:NSTextAlignmentCenter];
[textToDraw setEditable:YES];
// textOnImage is a regular NSString
[textToDraw insertText:textOnImage replacementRange:NSMakeRange(0, textOnImage.length)];
[textToDraw setTextColor:[NSColor blackColor]];
[textToDraw setFont:font];
[textToDraw setEditable:NO];
// input is an NSImage
[input lockFocus];
[textToDraw drawRect:NSMakeRect(8, inputImage.size.height - textToDraw.frame.size.height - 8, textToDraw.frame.size.width, textToDraw.frame.size.height)];
[input unlockFocus];

Instead of drawing textview on image you can provide the bounded rect in which text should be drawn. If the string is too long it wouldn't run off the image and will automatically enter in new line.
Here is code where inputImage is the image on which you want to draw text
NSImage *newImage = [[NSImage alloc] initWithSize:inputImage.size];
[newImage lockFocus];
[inputImage drawAtPoint:NSZeroPoint fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0];
[textStr drawInRect:boundedRect withAttributes:attrsDictionary];
[newImage unlockFocus];
