How to make a AVPlayerViewController go to fullscreen programmatically?

Question

I\'m trying to make a AVPlayerViewController go to full screen mode programmatically, coming from \"embedded\" mode, however this does not appear to be possible with the pub

Updated for iOS 11

There is no supported way to programmatically go fullscreen with AVPlayerViewController (a bit of an oversight in my opinion).

However, AVPlayerViewController does contain a private method that does exactly that. You'll have to decide for yourself whether you'd want to use it or not given you're not supposed to call private methods.

AVPlayerViewController+Fullscreen.h

#import 

@interface AVPlayerViewController (Fullscreen)

-(void)goFullscreen;

@end

AVPlayerViewController+Fullscreen.m

#import "AVPlayerViewController+Fullscreen.h"

@implementation AVPlayerViewController (Fullscreen)

-(void)goFullscreen {
    NSString *selectorForFullscreen = @"transitionToFullScreenViewControllerAnimated:completionHandler:";
    if (@available(iOS 11.3, *)) {
        selectorForFullscreen = @"transitionToFullScreenAnimated:interactive:completionHandler:";
    } else if (@available(iOS 11.0, *)) {
        selectorForFullscreen = @"transitionToFullScreenAnimated:completionHandler:";
    }
    SEL fsSelector = NSSelectorFromString([@"_" stringByAppendingString:selectorForFullscreen]);
    if ([self respondsToSelector:fsSelector]) {
        NSInvocation *inv = [NSInvocation invocationWithMethodSignature:[self methodSignatureForSelector:fsSelector]];
        [inv setSelector:fsSelector];
        [inv setTarget:self];

        NSInteger index = 2; //arguments 0 and 1 are self and _cmd respectively, automatically set
        BOOL animated = YES;
        [inv setArgument:&(animated) atIndex:index];
        index++;

        if (@available(iOS 11.3, *)) {
            BOOL interactive = YES;
            [inv setArgument:&(interactive) atIndex:index]; //arguments 0 and 1 are self and _cmd respectively, automatically set by NSInvocation
            index++;
        }

        id completionBlock = nil;
        [inv setArgument:&(completionBlock) atIndex:index];
        [inv invoke];
    }
}

@end
