I am using JASidePanels in iOS and trying to get the menu button to show on the right instead of the left (center panel is a UINavigationController so the left menu button gets replaced with the back button text) but I cannot seem to get the right button to show regardless of what I try.
I tried setting only a right panel (no left panel). Is there a way within JASidePanels to move the menu button from the left side of the navigation bar to the right side?
thanks
Add a new bar button to the navigation bar within your viewDidLoad method:
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Right"
style:UIBarButtonItemStylePlain
target:self
action:#selector(toggleRightPanel)];
and method to be called by right bar button:
- (void)toggleRightPanel {
[[self.parentViewController valueForKey:#"sidePanelController"] performSelector:#selector(toggleRightPanel:)];
}

My app is navigated by a slide out menu from the left. On top of each viewController is a left UIBarButton titled "Navigation", that when touched, opens the slide out menu without having to do the drag effect. I am implementing speech commands into my app, and if a user speaks "Go to Finances", it segues to a viewController titled FianceViewController through instantiateViewController to pushViewController.
This all works fine, the only problem is the back button associated with push segue covers up my "Navigation" button in the left slot of the UINavigationBar. Using self.navigationItem.hidesBackButton = YES; hides both the back button and my "Navigation" button. Is there anyway not make a back button appear when the push happens, but still allow my previously created "Navigation" bar button to be seen and used? Or is there another type of segue that I can do other than push if this UIBarButton dilemma cannot be solved?
Section of code that segues when spoken:
if ([title isEqualToString:#"FINANCES"])
{
FinanceViewController *fvc = [[self storyboard] instantiateViewControllerWithIdentifier:#"finance"];
[[self navigationController] pushViewController:fvc animated:YES];
}
How are you adding the navigation button?
I would try to add it after hiding the back button, something like this:
self.navigationItem.hidesBackButton = YES;
UIButton *navigationButton = [[UIButton alloc] initWithFrame:CGRectMake(15.0, 15.0, 100.0, 32.0)];
self.navigationController.navigationBar.backItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:navigationButton];
Instead of hiding my back button, I figured out I could simply write over it! Using fvc.navigationItem.leftBarButtonItem = self.navigationItem.leftBarButtonItem; before pushViewController, allows the "navigation" button to override the back button.
I have an app that uses bottom tabs aswell as a side menu, to have the button that initiates the side menu i use the typical three line menu button, to put that there I have a Navigation Bar. With the bar in place there is no way I can get the bar to be on top of the screen. I built it with interface builder, and heres a screenshot. The question is how do i have the navigation bar alone without the other grey bar above it?
The issue you're encountering is due to the fact that you're manually creating a navigation bar for your view controller, instead of using the bar that you get for free by embedding the view controller in a tab bar controller, hence the reason you see two bars. The other answer suggesting hiding the auto-generated navigation bar is not the correct solution. Instead, you should place your menu button and view title in the auto-generated bar instead of manually creating your own (you almost never want to do that, in-fact).
So what you should do instead is set the title property of your view controller to be "News", and the leftBarButtonItem property of the view controller to be your hamburger menu button (an instance of UIBarButtonItem initialized with an image for the icon).
For example (inside your view controller's viewDidLoad method or wherever appropriate):
self.title = #"News";
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"menuIcon"] style:UIBarButtonItemStylePlain target:self action:#selector(showSideMenu)];
If you want to remove the topmost navigation bar you need use self.navigationController.navigationBarHidden = YES; for view controllers that used for tabs in UITabBarController:
// StoriesViewController.m
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
self.navigationController.navigationBarHidden = YES;
}
I am working on ios Bar Button icon where I have to display UIsegmented control with two UIBarButton icon on the right site but when I try to add second button using interface builder the first added button get disappears
This is how the view is added:
View->Navigation Bar->Navigation Item-> BarButton Item-> Button
Can anyone help me to find the possible solution
UIBarButtonItem *item1=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:#selector(firstSelector)];
UIBarButtonItem *item2=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(secondSelector)];
NSArray *items=[[NSArray alloc]initWithObjects:item1,item2, nil];
self.navigationItem.rightBarButtonItems=items;
I have an app that uses a side menu and has a few main screens that can be accessed from the menu and others that can only be accessed from these screens.
What I want is to have a menu button on the navigation bar that opens the menu and can only be visible on the main screens. On the other screens I want to have a back button, instead of the menu button.
I've already put the menu button like this:
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"IconMenu"] style:UIBarButtonItemStylePlain target:self.revealViewController action:#selector(revealToggle:)];
But I can't figure out how to change it with the back button when I need it.
Assuming than by "main screens" you mean root (first) view controllers in the navigation view controllers corresponding to the selected side menu items, this might be a solution for your problem: you can create a superclass for all your view controllers, say MyBaseViewController and rewrite viewWillAppear: method, that will determine whether it should have a default back button or a "revealSideMenu" button, based on whether it's a "main screen" or not.
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if (self == [self.navigationController.viewControllers firstObject]) {
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"IconMenu"] style:UIBarButtonItemStylePlain target:self.revealViewController action:#selector(revealToggle:)];
}
}
you can do that in 2 different ways:
the first is in the viewDidAppear check if the back button is already present (when you push a VC the back button automatically added but is avalaible programmatically only after the viewDidAppear) and then decide to add or not the menu button,
the second is add a parameter to your VC init method like isRoot or hasMenu or whatever you like to name it, and using that flag decide to add the menu or the back button
if you chose to add your own back button you have to call this method in your back selector
[self.navigationController popViewControllerAnimated:YES];
The easiest way, IMO, is just to click on the title bar of the first ViewController and in the Attribute Inspector (⌥+⌘+4) change the Navigation Item info the way you want: Title -> what will show up in the back button* or if you want it to say something other than the Title of the first ViewController or the word "Back" you can just put it in the Back Button field.
*If the Title of the second ViewController is too long for it to fit it will be replaced with the word "Back" (and if the word "Back" doesn't fit it will only have the arrow sign).
I've tried this for hours but I still cannot solve it.
When using UINavigationController and push a new view controller on top, I got a free "back" button on the left of the navigation bar. I want another button just next to it (to show a popover menu). I wonder what is the correct way to do that. Or I have to hide the free back button and make the same one by myself? If that's the case, I also need to pop the current view controller when pressing my own back button, right?
Thanks for your help.
As stated by steipete in the comment to the question, this is possible starting from iOS 5. You can use
self.navigationItem.leftItemsSupplementBackButton = YES;
and then you just need to add an UIBarButtonItem as leftButton to get a second button after the back button
UIBarButtonItem *secondButton = [[UIBarButtonItem alloc] initWithTitle:#"Second" style:UIBarButtonItemStylePlain target:self action:#selector(yourAction)];
self.navigationItem.leftBarButtonItem = secondButton;
SWIFT 5 this worked for me. Thanks
self.navigationItem.leftItemsSupplementBackButton = true
