how to call UIViewController Class using Framework

Question

I Have create a Static library /Framework using this tutorial

For calling a view class customView **( type UIView )**we used below code

-(void) showMessageInViewController:(UIViewController *)viewController {
   if (_isEnabled) {
      NSBundle* frameworkBundle = [NSBundle bundleForClass:[self class]];
      CustomView *csView = [[frameworkBundle loadNibNamed:@"CustomView" owner:self options:nil] firstObject];
      csView.frame = CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width, [[UIScreen mainScreen] bounds].size.height);
      [viewController.view addSubview:csView];
   }
}

My Question is :

If i create a UIViewController Class inside my Framework then how i navigate or call it using my Class

-(void)showMessageInUIViewController:(UIViewController *)uiviewController
{
DetailViewController *viewController = [[DetailViewController alloc]
                                       initWithNibName:@"DetailViewController"
                                                bundle:nil];
viewController.delegate = self;
UINavigationController *navController = [[UINavigationController alloc]
                                        initWithRootViewController:viewController];
[self presentModalViewController:navController animated:YES];
}

It shows error in .delegate and presentModalViewController

You can Use Have a reference to the UIViewController that you uses your framework currently. in InsertManager.h

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface InsertManager : NSObject

+(instancetype) sharedManager;
-(void) setViewController; // the view controller will use it to assign itself to the framework. 
-(void) startManager;
-(void) stopManager;

-(void) showMessageInViewController:(UIViewController *)viewController;

-(BOOL) isManagerRunning;

@end

in InsertManager.m

#import "InsertManager.h"
#import "CustomView.h"

@interface InsertManager()

@property (nonatomic) BOOL isEnabled;
@property (readOnly) BOOL hasViewController;
@property (nonatomic, weak) CustomView * csView;

@end

@implementation InsertManager

+ (instancetype) sharedManager {
   static InsertManager *sharedManager = nil;
   static dispatch_once_t onceToken;
   dispatch_once(&onceToken, ^{
      sharedManager = [[[self class] alloc] init];
      // create the custom view only once. 
       NSBundle* frameworkBundle = [NSBundle bundleForClass:[self class]];
      _csView = [[frameworkBundle loadNibNamed:@"CustomView" owner:self options:nil] firstObject];
      csView.frame = CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width, [[UIScreen mainScreen] bounds].size.height);
   });
   return sharedManager;
}
-(Bool) hasViewController {
      return _viewController != nil;
   }

- (void) setViewController:(UIViewController *) viewController {
      _viewController = viewController
     // add the views you want to it all at once, but keep them hidden.
     _csView.hidden = YES;
     [_viewController.view addSubview:csView];
    }
- (void) startManager {
   NSLog(@"Manager is running");
   _isEnabled = YES;
}

- (void) stopManager {
   NSLog(@"Manager stopped..");
   _isEnabled = NO;
}

-(BOOL) isManagerRunning {
   return _isEnabled;
}

-(void) showMessage {
   if (_isEnabled && _hasViewController) {
      // Only unhide the custom view as its already added to the _viewController and hidden.
       _csView.hidden = NO;
   }
}

@end 

CustomView.m

  #import "CustomView.h"

    @implementation CustomView

    - (IBAction)closeButtonClicked:(id)sender {
       // [self removeFromSuperview];
       self.hidden = YES;
    }
@end

I hope this helps. It might needs a bit of tweaking as I just wrote it here(no compilier). Thanks.
