How can i update one of viewcontollers when i go to KLControllerCardStateDefault state? about klnoteviewcontroller HOT 30 CLOSED

What is the behaviour when you do this? Although you are using the control to organize your UINavigationControllers, the behaviour of the navigation controllers will not change as a result of being contained within the KLNoteViewContoller.

I would attempt to do it using the method call rather than the accessor. i.e. try
[self.navigationItem setLeftBarButtonItem: nil animated: YES/NO];

from klnoteviewcontroller.

The behaviour - nothing happens. i tried
[self.navigationItem setLeftBarButtonItem: nil animated: YES/NO];
nothing happens.

The problem, that if i set action on button within view:
-(void)DeleteLeftItem:(id)sender {
[self updateUI];
}
and press this button, leftbaritem will be removed, but when i call updateUI in noteviewcontroller delegate, nothing happens.

Have you put a breakpoint to see if the code is being executed?

i tried set navbar title in updateUI, but I did not get

from klnoteviewcontroller.

Ah I think I know what is wrong

you need to do

self.navigationController.navigationItem.leftBarButtonItem = nil;

from klnoteviewcontroller.

otherwise check fi self.navigationItem is nil or not to see if you are actually referencing anything

from klnoteviewcontroller.

i tried self.navigationController.navigationItem.leftBarButtonItem = nil;
nothing happens.

and i check self.navigationItem is nill or not - it's not nil.

from klnoteviewcontroller.

Can you try to add 3-4 viewcontrollers to klnoteviewcontroller and update title or right or left bar item when viewcontrollers go to KLControllerCardStateDefault state?
Maybe i do anything wrong.

from klnoteviewcontroller.

tbh this is a navigationcontroller issue not related to the control. As mentioned previously the control just organizes UIViewControllers, what you do with the UIViewControllers/UINavigationControllers is up to you. Try performing the same operation with the UINavigationController outside of the control and see if it works

I try to change nav item title and rightbaritem from uibutton action and everything is ok.
but when i try to do this in
-(void) noteViewController: (KLNoteViewController_) noteViewController didUpdateControllerCard:(KLControllerCard_)controllerCard toDisplayState:(KLControllerCardState) toState fromDisplayState:(KLControllerCardState) fromState {}, nothing happens,unfortunately

from klnoteviewcontroller.

Try

if (toState == KLControllerCardStateDefault) {
NSIndexPath path = [self indexPathForControllerCard:controllerCard];
TDListViewController viewController = (TDListViewController *)[self noteView:self viewControllerForRowAtIndexPath:path];
viewController.navigationController.navigationItem.leftBarButtonItem= nil;
}

}

from klnoteviewcontroller.

just throwing out ideas... :P

from klnoteviewcontroller.

i tried that :) unfortunately, nothing happens

from klnoteviewcontroller.

try performing [noteView reloadDataAnimated:NO]; after the change

from klnoteviewcontroller.

Using a break poing check if the line :

TDListViewController viewController = (TDListViewController *)[self noteView:self viewControllerForRowAtIndexPath:path];

is actually returning a TDListViewController and not a UINavigationController

from klnoteviewcontroller.

Just a note as well, in the code:

NSIndexPath path = [self indexPathForControllerCard:controllerCard];
TDListViewController viewController = (TDListViewController *)[self noteView:self viewControllerForRowAtIndexPath:path];
viewController.navigationController.navigationItem.leftBarButtonItem= nil;

you need a * after NSIndexPath and TDListViewController

from klnoteviewcontroller.

i understand

from klnoteviewcontroller.

TDListViewController viewController = (TDListViewController *)[self noteView:self viewControllerForRowAtIndexPath:path];

it's return me right TDListViewController with right variables

from klnoteviewcontroller.

try performing [noteView reloadDataAnimated:NO]; after the change
if (toState == KLControllerCardStateDefault) {
NSIndexPath *path = [self indexPathForControllerCard:controllerCard];
TDListViewController *viewController = (TDListViewController *)[self noteView:self viewControllerForRowAtIndexPath:path];
viewController.navigationController.navigationItem.leftBarButtonItem= nil;
viewController.navigationItem.leftBarButtonItem= nil;
[self reloadDataAnimated:NO];
}

if i run this code, i have exception:

Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[_PFArray objectAtIndex:]: index (2147483647) beyond bounds (2)'

from klnoteviewcontroller.

Note you can also get the uiNavigationController reference by simply doing controllerCard.navigationController

from klnoteviewcontroller.

Maybe the problem in my

• (UIViewController )noteView:(KLNoteViewController)noteView viewControllerForRowAtIndexPath:(NSIndexPath *)indexPath {

  //Initialize a blank uiviewcontroller for display purposes
  UIStoryboard st = [UIStoryboard storyboardWithName:[[NSBundle mainBundle].infoDictionary objectForKey:@"UIMainStoryboardFile"] bundle:[NSBundle mainBundle]];
  TDListViewController viewController = [st instantiateViewControllerWithIdentifier:@"ListRootViewController"];
  viewController.list = self.listsData[indexPath.row];
  //Return the custom view controller
  return viewController;
  }

from klnoteviewcontroller.

You need to have * after UIStoryboard and TDListViewController. You are initializign a pointer

from klnoteviewcontroller.

Be sure you understand what the * actually means in the context of assignment

from klnoteviewcontroller.

you must be getting warnings for that no?

from klnoteviewcontroller.

I understand, i paste this piece of code from xcode, but in xcode i have * when it's nessesary, but there * are hidden. So strange

from klnoteviewcontroller.

ahhh ok I thought you were just not using them and was wondering how it was even working :P

from klnoteviewcontroller.

If I did not have *, my code won't be compiled

from klnoteviewcontroller.

I try a dirty hack. i add viewController property to KLControllerCard.
@Property (nonatomic, strong) UIViewController* viewController;

And in reloadData add:
UIViewController* viewController = [self noteView:self viewControllerForRowAtIndexPath:[NSIndexPath indexPathForRow:count inSection:0]];

    UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];

    KLControllerCard* noteContainer = [[KLControllerCard alloc] initWithNoteViewController: self
                                                                                navigationController: navigationController
                                                                                               index:count];

// i add this line
noteContainer.viewController = viewController;

And now in
-(void) noteViewController: (KLNoteViewController_) noteViewController didUpdateControllerCard:(KLControllerCard_)controllerCard toDisplayState:(KLControllerCardState) toState fromDisplayState:(KLControllerCardState) fromState {
if (toState == KLControllerCardStateDefault) {
[((TDListViewController *)controllerCard.viewController) updateUI];
}

}

Do you think it looks like a patch to your component? :P
