Customization of MMDrawerController | Notification badge over MMDrawer on left-side | Crash on slide

#import <QuartzCore/QuartzCore.h>

 - (void)setupNavigationBar:(id)target withNotificationBadge:(NSUInteger)badgeValue{

  UIViewController *ctr = (UIViewController *)target;
  CGRect leftFrame = CGRectMake(0,0,30,44)
  UIView *view = [[UIView alloc] initWithFrame:leftFrame];
  // logo Button
  UIButton *logoBtn = [UIButton buttonWithType:UIButtonTypeCustom];
  logoBtn.frame = CGRectMake(0,7,30,30);
  logoBtn.userInteractionEnabled = YES;
  [logoBtn setBackgroundImage:[UIImage imageNamed:@"YOUR_IMAGE_NAME"]forState:UIControlStateNormal];
  [logoBtn addTarget:ctr action:@selector(leftDrawerButtonPress:) 
  forControlEvents:UIControlEventTouchUpInside];
  [view addSubview:logoBtn];
  // Notification Badge
   if (badgeValue > 0){
       NSInteger armLength = 20;
       UILabel *badgeLbl = [[UILabel alloc] init];
       badgeLbl.frame = CGRectMake(25, 2, armLength, armLength); 
       badgeLbl.text = [NSString stringWithFormat:@"%i",badgeValue];
       badgeLbl.layer.cornerRadius = armLength/2;
       badgeLbl.layer.masksToBounds = YES;
       badgeLbl.backgroundColor = [UIColor redColor];
       badgeLbl.textColor = [UIColor whiteColor];
       badgeLbl.font = [UIFont systemFontOfSize:11.0f];
       badgeLbl.textAlignment = UITextAlignmentCenter;

Drawer Button click function To use instance of MMDrawerController, you just need to do #import "UIViewController+MMDrawerController.h"

- (void)leftDrawerButtonPress:(id)sender{
    [self.mm_drawerController toggleDrawerSide:MMDrawerSideLeft animated:YES completion:nil];
}

In MMDrawerController.m file 

other fixes:
1. Orientation in Portrait mode only instead of supporting all orientations they provide by default.

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
  return  (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}

2. Drawer sliding either one of side
you must handle, drawerSide is not Equal to MMDrawerSideNone check, find given below:

-(void)updateDrawerVisualStateForDrawerSide:(MMDrawerSide)drawerSide percentVisible:(CGFloat)percentVisible{
  if(self.drawerVisualState){
       if(drawerSide != MMDrawerSideNone)
            self.drawerVisualState(self,drawerSide,percentVisible);
  } else if(self.shouldStretchDrawer){
        [self applyOvershootScaleTransformForDrawerSide:drawerSide percentVisible:percentVisible];
    }
}

output:

55: Badge value
AJ is an icon with white background.
