Above is the crash log for my app, I am not getting any idea, what could be the cause of the crash?Does it have to be because of UIPopoverController or because of PresentPopoverFromRect. Any kind of help is greatly appreciated.
Thanks in advance :)
Code added...
try to make
#property (strong, nonatomic) UIPopoverController *uiCustomPopover;
and then:
self.uiCustomPopover = [[UIPopoverController alloc] initWithContentViewController:self.TestAppDisplayPopoverViewController];
[self.uiCustomPopover setPopoverContentSize:CGSizeMake(354.5, 229.5)];
self.uiCustomPopover.delegate=self;
[self.uiCustomPopover presentPopoverFromRect:CGRectMake(250,15.0, 1.0, 1.0) inView:someView permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
That should help. I also had the same problem like UIPopoverController did deallocated before presented or something...

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];

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.
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.
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.

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.
I am having a weird crash related to a UILabel but the crash reporting service I am using doesn't give me much help to locate it. I can't know which Controller and which UILabel is causing it. The only help I have is the following:

Is there anything I can find my way through this? Thanx in advance!
Even though it's an old question, for anyone that encounters a similar issue:
If you're using attributedText in your UILabel, check the attribute value types you're setting. For example:
NSString* s = #"str";
NSMutableAttributedString* as = [[NSMutableAttributedString alloc] initWithString:s];
[as addAttribute:NSForegroundColorAttributeName value:someObjectThatsNotAUIColor range:NSMakeRange(0, s.length)];
will cause the UILabel [__NSCFString set]: unrecognized selector sent to instance crash.
You could try to put this in a .h :
#interface NSString (extended)
- (void)set;
#end
And this in a .m :
#implementation NSString (extended)
- (void)set
{
NSLog(#"[NSString set] ??? impossible !!!");
}
#end
Then set a breakpoint on this method.
Search your project for " set]" then you'll probably already find it, as this is a very untypical method name. If that doesn't help, use NSLog to print out all your labels adresses to your console to find out which label is causing this. Like
for (UIView *sub in self.subviews)
if ([sub kindOfClass:[UILabel class]]) NSLog(#"%p", sub);
(code untested, correct spelling if necessary)
When i used this code in iPhone 4.3 simulator , i got this error but when run it on iPhone 5 simulator ,it's worked without errors .
Code
UITabBarController *tabB = [[UITabBarController alloc] init];
tabB.tabBar.tintColor=[UIColor colorWithRed:124.0/255.0 green:150.0/255.0 blue:32.0/255.0 alpha:1.0];
tabB.tabBar.selectedImageTintColor=[UIColor colorWithRed:187.0/255.0 green:255.0/255.0 blue:38.0/255.0 alpha:1.0];
tabB.viewControllers = [NSArray arrayWithObjects:hc,bt, nil];
[self.navigationController pushViewController:tabB animated:YES];
Error

A good way to make this version independent is:
if ([tabBarController.tabBar respondsToSelector:#selector(setTintColor:)]) {
[tabBarController.tabBar setTintColor:color];
}
In IOS 5 this will set the tabbar tintcolor and in lower versions it wont crash
According to the documentation tintColor is only available in iOS 5.0 and later. The clue was that the 4.3 simulator is saying unrecognized selector sent to instance which basically means the method doesn't exist.
You'll need to do one of the following:
Set your minimum required iOS to 5.0.
Only apply the tint when running on iOS 5.0 or greater.
Use an alternative method supported by both versions.
Documentation Excerpt:
tintColor
The tint color to apply to the tab bar background.
#property(nonatomic, retain) UIColor *tintColor Availability
Available in iOS 5.0 and later.
try this
tabB.tintColor=[UIColor colorWithRed:124.0/255.0 green:150.0/255.0 blue:32.0/255.0 alpha:1.0];
