I used third party code (menu) in my application to change my navigation controller back button title. Therefore I used code like this:
self.navigationItem.hidesBackButton = YES;
self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:#"Geri" style :UIBarButtonItemStyleBordered target:self action:#selector(myCustomBack)] autorelease];
This code work fine but there is no default left arrow image in iOS 7, also rectangle button created in iOS 6. How can I add default left image (not custom) in back button?
You need own arrow image.
Create regular UIButton with custom style and background image (arrow) also set action, then create UIBarButtonItem and put this button as custom view;

I have a screen that displays some info in a textview and I would like the user to be able to edit it.
Right now, I have an edit button on the right side of the navigation bar that I create in code as follows:
UIBarButtonItem *editButton = [[UIBarButtonItem alloc] initWithTitle:#"Edit" style:UIBarButtonItemStylePlain target:self action:#selector(gotoEdit)];
self.navigationItem.rightBarButtonItem = editButton;
For editing, I could launch a new view controller but it would be cleaner, I think, to just use the textview.editable property to make the text view editable.
However, I would then need to change the title and function of the uibarbuttonitem from edit to save.
You apparently cannot change the title of a system edit button and I'd just as soon not create a custom bar button item although this may ultimately prove necessary.
It is possible to hide bar button items by making their color clear and disabling interaction. Therefore, I had the idea of putting two in the same place and hiding and showing them accordingly.
Hence my question. Is it possible to put two in the same place?
Thanks for any ideas on this.
If you are using storyboards...you can drag and drop a UIButton to the rightBarButtonItem. Make this button a property and set the initial title to "Edit".
In the Action:
- (IBAction) editButton (id){
if(!isEditing){
// Prep for editing
[self.editButton setTitle:"Save" forState:UIControlStateNormal];
isEditing = true;
}else{
// Prep for save
[self.editButton setTitle:"Edit" forState:UIControlStateNormal];
isEditing = false;
}
}
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:)];
}
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 am currently working with a UISplitViewController and instead of having this default slide-out-menu, i want a real UIPopover that appears if i click the UIBarButtonItem. What do i have to do and is there an easy way of configuring this ?
You first need to overwrite the left bar button item, with the button that can be used to display the popover.
Use the following -
UIBarButtonItem *barBtn = [[UIBarButtonItem alloc] initWithTitle:#"Popover" style:UIBarButtonItemStylePlain target:self action:#selector(presentPopover:)];
self.navigationItem.hidesBackButton = NO;
self.navigationItem.leftBarButtonItem = nil;
Now you can use the target added, and then perform the associated function, as per your choice.
-(IBAction)presentPopover:(id)sender
{
// Perform your operations
}
Then just use a popover view controller instead with the same content you would have used in the splitview pane that slides out.
I would like to setup the navigation controller bar button item to be an image.
I have read the following - Add image to a navigationItem's title
I understand how to setup this as an image. I am actually looking to set this up as the setting cog, within the bar button item (like a cog icon). I have seen this before in other apps, I would like to know if there is a default style to initialise for this or normally if this is achieved by the image route as above.
If this is above, does anyone know where this (kind of) default image styled icon is available, or would I need to make one?
Have you tried using the initWithCustomView option of UIBarButtonItem? A sample code will look like the below line.
UIBarButtonItem *aButton = [[UIBarButtonItem alloc] initWithCustomView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"settings.png"]]];
Another way to do this is,
UIBarButtonItem *aButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"settings.png"] style:UIBarButtonItemStyleBordered target:self action:#selector(buttonTapped)];
If you use storyboard, you can directly:
Drag a Button in the navigation bar instead of a Bar Button Item. It will automatically create a Button Bar Item for you with a Button inside it.
Enter a title for the Button Bar Item
Set an image for the Button with a Custom type.
It should works.
