Im trying to create a New UISPlitViewController and display it instead of current ViewController, but for some reason it's not working, it says:
-[UISplitViewController navigationBar]: unrecognized selector sent to instance
this is the code
- (IBAction)openDocuments:(id)sender {
UINavigationController *leftNavController;
UINavigationController *rightNavController;
MenuDocumentsVC *masterVC = [self.storyboard instantiateViewControllerWithIdentifier:#"MenuDocumentsVC"];
masterVC.title = #" ";
ContentDocumentsVC *detailVC = [self.storyboard instantiateViewControllerWithIdentifier:#"ContentDocumentsVC"];
detailVC.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:LOGO_COMPANY]];
masterVC.delegate = detailVC;
leftNavController = [[UINavigationController alloc] initWithRootViewController:masterVC];
rightNavController = [[UINavigationController alloc] initWithRootViewController:detailVC];
leftNavController.toolbarHidden = FALSE;
rightNavController.toolbarHidden = FALSE;
leftNavController.navigationBar.translucent = FALSE;
rightNavController.navigationBar.translucent = FALSE;
leftNavController.toolbar.translucent = FALSE;
rightNavController.toolbar.translucent = FALSE;
UISplitViewController *splitViewController = [[UISplitViewController alloc] init];
splitViewController.viewControllers = [NSArray arrayWithObjects:leftNavController, rightNavController, nil];
splitViewController.delegate = (id)detailVC;
if ([splitViewController respondsToSelector:#selector(setPresentsWithGesture:)]) {
[splitViewController setPresentsWithGesture:NO];
}
splitViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[UIView transitionWithView:self.view.window
duration:0.5
options:UIViewAnimationOptionCurveEaseOut
animations:^{
self.view.window.rootViewController = splitViewController;
} completion:^(BOOL finished) {
}];
}
how to make it work properly??

From provided log I can say that problem lie in [ContentDocumentsVC viewWillAppear:] where you set color to navigation bar with category method setNavigationBarControllerToHexColor: but looks like you call this method on wrong controller.

While adding child viewcontroller, I am getting following crash,
Here NavigationViewController is extended from UIViewController.
This error is coming when I upgraded to Xcode 9, working successfully on earlier versions of Xcode.
I referred the Link but not getting any satisfied answer, please help me out this,
Thanx in advance. :)
The block of code is:
_mainSectionsController = [[[MainSectionsController alloc] initWithNibName:nil bundle:nil] autorelease];
[self addChildViewController:_mainSectionsController];
**Init method of _mainSectionsController** .
-(id)initWithNibName:(NSString*)nibNameOrNil bundle:(NSBundle*)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (!self) return nil;
self.edgesForExtendedLayout = UIRectEdgeAll;
self.viewControllers = #
[
[[[NavigationViewController alloc] initWithNibName:nil bundle:nil]
autorelease]
];
return self;
}

Since you have autorelease in your MainSectionsController code I assume that you don't use ARC there. I highly recommend upgrading the code of MainSectionsController and NavigationViewController to ARC. This prevents accidental overreleases that might cause issues like this one.
In addition I'd recommend to move self.viewControllers assignment from the constructor to viewDidLoad if possible.
I have a WebView in my storyboard. I created an outlet property to that webview in my view controller file. Then in my code in I'm calling it like this:
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"news1" ofType:#"html" inDirectory:#"/HTML"]];
[self.webView loadRequest:[NSURLRequest requestWithURL:url]];
}
The problem is my app is crashing when I run this and I don't really know why. I get this error, but I need help deciphering what the issue is.

The HTML file isn't in your bundle or isn't at the path specified. Check the case of the file and folder name. If you build/run in the simulator, you can look through the bundle inside of ~/Library/Application Support/iPhone Simulator/7.1/Applications.
Don't use loadRequest if you want to load html locally. use this
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:#"sample" ofType:#"html"];
NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
[webView loadHTMLString:htmlString baseURL:nil];
I try to present a UIImagePickerController from rect using this code:

imgPickerController.allowsEditing = NO;
_popover = [[UIPopoverController alloc] initWithContentViewController:imgPickerController];
[_popover setDelegate:self];
[_popover presentPopoverFromRect:CGRectMake(195, 55, 70, 64) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:NO];

Finally, I decided use a AssetsLibrary framework to create a custom UIImagePickerController using this MyImagePicker sample:
https://developer.apple.com/library/ios/samplecode/myimagepicker/Introduction/Intro.html
I ran into an issue when testing my application in iOS7. The application currently runs just fine in iOS5 and iOS6. Based on the stack trace, it would appear that a private method is causing the issue.

libc++abi.dylib: terminating with uncaught exception of type NSException
This crash happens only when testing in iOS7. It happens as soon as [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil] is called. I cannot find any information about _confirmBarAccessMethods. I assume it is a private UINavigationController method.
Here is the header file for the CustomUINavigationController class:
#import <UIKit/UIKit.h>
#import "CustomUINavigationBar.h"
#interface CustomUINavigationController : UINavigationController
{
CustomUINavigationBar *customNavigationBar;
}
#property (nonatomic, retain) UIColor *titleColor;
#end
This is the init method in which the application crashes:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; // This line causes the application to crash
if (self) {
customNavigationBar = [[CustomUINavigationBar alloc] init];
[customNavigationBar setTintColor:[UIColor colorWithWhite:0.0 alpha:1.0]];
[customNavigationBar setItems:[NSArray array] animated:NO];
[customNavigationBar setDelegate:self];
self.titleColor = [UIColor colorWithWhite:1.0 alpha:1.0];
}
return self;
}
Here is the header file for CustomNavigationBar:
#import <UIKit/UIKit.h>
#interface CustomUINavigationBar : UINavigationBar
{
UIImage *background;
}
#end
Any help would be greatly appreciated. I can provide more information if necessary.
EDIT: Added trace from suggested solution of using custom navigation bar initializer

Create the navigation controller with initWithNavigationBarClass:toolbarClass: and supply your custom navigation bar class. Then perform any configuration you require on the instance created for you by the nav controller superclass.
I finally resolved the issue. CustomerUINavigationController had an override method for the navigationBar accessor. It was attempting to return a nil value. I removed this and the application compiled and ran with no issues.
if (! self.mainPage)
{ self.mainPage= [[MainGameDisplay alloc] initWithNibName:nil bundle:nil]; }
[self presentViewController: self.mainPage animated:YES completion:NULL];
[self.view addSubview:self.mainPage.view];
self.mainPage.view.frame = CGRectMake(568, 0, 568, 320);//(N = horizontal, N = vertical)
[UIView animateWithDuration:1.0f
animations:^{
//actual frame needed with an animation.
self.mainPage.view.frame = CGRectMake(0, 0, 568, 320);
}
completion:^(BOOL finished) {
//ENTER HERE ANYTHING TO RUN AFTER ANIMATION IS COMPLETED:
[self presentViewController: self.mainPage animated:NO completion:NULL];
//This will make the next page load correctly after the transition, otherwise you cannot. interact with anything.
}];
#property (strong) MainGameDisplay *mainPage;
is declared in the .h file.
This code works perfectly but only once, If I was to transition to the mainPage view, come back and transition there again, it would crash at the end of the transition. I've played around so much to fix this but it just doesn't work.

maybe you release you property in viewDidDisapear or something like this ?
what type of crash - BAD_ACCESS ?
