However the following code and output indicates differently. Is it because I don't have an explicit controller?
Code
// create set time window
NSLog(#"Set Time...");
NSLog(#"View %#", self.statusTime.view);
NSLog(#"Frame %#", self.statusTime.view.frame);
NSPopover *popover = [[NSPopover alloc] init];
NSLog(#"Showing popover...");
[popover showRelativeToRect:[self.statusTime.view frame]
ofView:self.statusTime.view
preferredEdge:NSMinYEdge];
Output

You need to set the contentViewController (what the popover is actually showing) before showing it.
i.e.
NSViewController *viewController; // some view controller created programmatically or from a nib
NSPopover *popover = [[NSPopover alloc] init];
popover.contentViewController = viewController; // Missing this.
NSLog(#"Showing popover...");
[popover showRelativeToRect:[self.statusTime.view frame]
ofView:self.statusTime.view
preferredEdge:NSMinYEdge];
The ofView: parameter is just where the popover is being shown from.

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.edgesForExtendedLayout = UIRectEdgeAll;
self.viewControllers = #

];
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.
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 try to present a UIImagePickerController from rect using this code:
UIImagePickerController* imgPickerController = [[UIImagePickerController alloc] init];
imgPickerController.delegate = self;
imgPickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imgPickerController.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeImage, nil];
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];
But sometimes crash happends... NO always, sometimes run, sometimes crash...

EDIT
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
Here is the code. I tried to create a object which includes the name, size and image(get from the resource) and then I add that object into NSMutableArray in order to show those object in NSTableView. However, after I run the code, I did get the correct counts of object in NSMutableArray and correct information in each object(name,size,image), but it still gives me error. Could you guys help me. I am a new Mac developer. Thanks !!
Here is the code:
#implementation AppDelegate{
NSMutableArray* _tableContents;
}
-(void)awakeFromNib{
NSString* imagePath = #"USB.png";
NSString* mountPath = #"/Volumes";
_tableContents = [[NSMutableArray alloc]init];
for(mountPath in [[NSWorkspace sharedWorkspace]mountedLocalVolumePaths])
{
if(0==[mountPath rangeOfString:#"/Volumes/"].location)
{
NSString* USBpath = [[[NSWorkspace sharedWorkspace]mountedLocalVolumePaths]objectAtIndex:count];
//get the name of USB drive
NSString* nameOfUSB = [USBpath substringFromIndex:9];
//get the size of USB drive
NSNumber *volumeSize;
NSURL *mountPathPicked = [NSURL fileURLWithPath:mountPath];
if([mountPathPicked getResourceValue:&volumeSize forKey:NSURLVolumeTotalCapacityKey error:nil])
{
NSDictionary *obj = #{#"name":nameOfUSB,
#"image":[NSImage imageNamed:imagePath],
#"size":volumeSize
};
//after I call the following line, it will give me error !!
[_tableContents addObject:obj];
}
}
count ++;
}
}
//I also use the following two methods in order to show the name, and image in NSTableView
-(NSInteger)numberOfRowsInTableView:(NSTableView *)tableView{
return [_tableCountents count];
}
-(NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row{
NSDictionary *flag = _tableContents[row];
NSString *identifier = [tableColumn identifier];//call different col we need identifier
if([identifier isEqualToString:#"MainCell"])
{
NSTableCellView *cellView = [tableView makeViewWithIdentifier:#"MainCell" owner:self];//give back specific cell named mainCell
[cellView.textField setStringValue:flag[#"name"]];
[cellView.imageView setImage:flag[#"image"]];
return cellView;
}
return nil;
}
There is no connection problems in GUI. And here is the error message:

And the above error shows twice !!
I have tried your code in a mini-app and It works fine. There are few things that I might highlight:
Your exception occurs in the method DetectingUSBDrives, for which we don't have any code. I'm assuming that you have pasted the code in the awakeFromNib method.
You are using count as an index. Is this varibale initialized at zero?
The fact that the error appears twice suggests that your cell views hold a reference to your app delegate, which means that awakeFromNib is called once for each view creation. This can create many problem since you are initializing _tableOfContents there. You might want to move all that code to the init method instead.
When I run the following Code it crashes at the last line. I don't have any idea why. This function gets called in awakeFromNib.
- (void)setMotdText:(NSString *)text
{
NSString *boldFontName = [[NSFont boldSystemFontOfSize:12] fontName];
NSMutableAttributedString *attrstr = [[NSMutableAttributedString alloc] initWithString:text];
[attrstr beginEditing];
[attrstr addAttribute:NSFontAttributeName value:boldFontName range:NSMakeRange(0, 16)];
[attrstr endEditing];
[self.motdTextView.textStorage setAttributedString:attrstr];
}
I get this crash log:

terminate called throwing an exception(lldb)
Has anybody an idea? If I call it with a NSAttributedString-Object there´s no error.
I had to change the first line to:
NSFont *boldFont = [NSFont boldSystemFontOfSize:12];
Now it works, because the value attribute requires a NSFont-Object and not a NSString with the fonts name.
This is the working Code:
- (void)setMotdText:(NSString *)text
{
NSFont *boldFont = [NSFont boldSystemFontOfSize:12];
NSMutableAttributedString *attrstr = [[NSMutableAttributedString alloc] initWithString:text];
[attrstr beginEditing];
[attrstr addAttribute:NSFontAttributeName value:boldFont range:NSMakeRange(0, 16)];
[attrstr endEditing];
[self.motdTextView.textStorage setAttributedString:attrstr];
}
