ios 13 presentViewController

typedef NS_ENUM(NSInteger, UIModalPresentationStyle) {
    UIModalPresentationFullScreen = 0,
    UIModalPresentationPageSheet API_AVAILABLE(ios(3.2)) API_UNAVAILABLE(tvos),
    UIModalPresentationFormSheet API_AVAILABLE(ios(3.2)) API_UNAVAILABLE(tvos),
    UIModalPresentationCurrentContext API_AVAILABLE(ios(3.2)),
    UIModalPresentationCustom API_AVAILABLE(ios(7.0)),
    UIModalPresentationOverFullScreen API_AVAILABLE(ios(8.0)),
    UIModalPresentationOverCurrentContext API_AVAILABLE(ios(8.0)),
    UIModalPresentationPopover API_AVAILABLE(ios(8.0)) API_UNAVAILABLE(tvos),
    UIModalPresentationBlurOverFullScreen API_AVAILABLE(tvos(11.0)) API_UNAVAILABLE(ios) API_UNAVAILABLE(watchos),
    UIModalPresentationNone API_AVAILABLE(ios(7.0)) = -1,
    UIModalPresentationAutomatic API_AVAILABLE(ios(13.0)) = -2,
};

开发中在跳转前指定退出控制器的模式就好了：

UIViewController * testVC = [[UIViewController alloc] init];
 controller.modalPresentationStyle = UIModalPresentationFullScreen;
    [rootControl presentViewController:testVC animated:NO completion:nil];
