Print panel accessory view shows in OS X 10.11, but not in 10.10 and 10.9

Question

My OS X app supports 10.9 - 10.11. I try to add some options to a printing operation by adding a print accessory view like this:

MyPrintView *printView = [[MyPrintView alloc] initWithData: [self myData]];
NSPrintOperation *printOperation = [NSPrintOperation printOperationWithView: printView];
NSPrintPanel *printPanel = [printOperation printPanel];
[printPanel addAccessoryController:[[MyPrintAccessory alloc] init]];
if (printOperation)
{
    [printOperation runOperationModalForWindow:_window delegate:_window didRunSelector:nil contextInfo:nil];
}

The accessory view is defined by a controller

@interface MyPrintAccessory : NSViewController <NSPrintPanelAccessorizing>

and a view defined in a xib file.

All works perfectly as expected in El Capitan, but in Yosemite and Mavericks while the print panel let's me choose my accessory in the pop-up button, if I choose it, nothing is displayed, the space where the accessory view should be displayed remains empty. No error messages are generated neither at compile nor at runtime.

Does anybody have a hint on how to solve this, or a hint, how to search for the cause of this behaviour?

When you say "No error messages are generated neither at compile nor at runtime", does that include looking at the system log using *Console.app*? — trojanfoe, Apr 11 '16 at 13:42

I had the same problem. I solved it by setting the option "Use Auto Layout" to off of my print accessory view nib file.

My application does the same thing, and works in 10.10

There is a slight difference, but to preface: My application is an NSDocument-based application. When printing, I grab the NSPrintInfo from the NSDocument, and feed it to my print method (the code you have embedded in your question)

Looks like this:

[printView requestPrintWithPrintInfo:[doc printInfo]];

Then, instead of calling -printOperationWithView:, I call -printOperationWithView:printInfo:, and I pass the printInfo that came from the sender

From Apple's docs, you should call -printOperationWithView when:

/* Slight conveniences, for use when the application's global NSPrintInfo is appropriate. Each of these methods invokes [NSPrintInfo sharedPrintInfo] and then invokes the like-named method listed above.

To me it sounds like it should work anyways, but like I said that's seemingly the only difference in our code

Have you investigated if the nib/xib is loaded correctly? Because I think before 10.10 you have to either name it explicitly via `(id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)bundle` or override the initializer in your NSViewController subclass accordingly. — MartinW, Apr 11 '16 at 18:03
