I've a WebviewViewController and a navigation bar with the Back Bar Button. Now I want two buttons on the right of the bar, a goBack and a goForward. I've searching for a while and none of the answers works properly.
There's a way to add them in the storyboard or only programmatically? If so, how do I do it?
I did it in the past, it's easy:
myBackBarButton = [[UIBarButtonItem alloc] initWithImage:barButtonImage
style:UIBarButtonItemStylePlain
target:myWebView
action:#selector(goBack)];
myForwardButtom = [[UIBarButtonItem alloc] initWithImage:anotherBarButtonImage
style:UIBarButtonItemStylePlain
target:myWebView
action:#selector(goForward)];
Where myWebView is your UIWebView (In case it's your class, use self)
If your buttons are already created, then just add the target and the action to them:
myBackButton.target = myWebView;
myBackButton.action = #selector(goBack);
What you are doing is adding the action goForward: and goBack: of the target that is your webview, to those buttons.

I've added a UISegmentedControl to a UINavigation Bar, and when I tried to add a UIBarButtonItem programmatically in viewDidLoad viewController using the following code:
UIBarButtonItem *timeTableBarButton = [[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:#"blueRoundRect"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(popUpTimeTable)];
self.navigationItem.rightBarButtonItem = timeTableBarButton;
There are no button showing at all. I wonder since I already have a UISegmentedControl, is it possible to do so?
It is possible to add the Bar button in navigation bar and there is no way your segment control should be blocking right bar button item. Please make sure that your self.navigationItem is not nil.
I feel daft asking this question, but I haven't been able to get this to work. I have a NavController->TableViewController->WebViewController. I'm trying to change the title of the backButton on the WVC from the default "Back" to "Reference".
This should be a simple matter of setting the text property of the Back button either in Storyboard (which isn't working) or in code of my WebViewController's viewDidLoad method:
self.navigationItem.backBarButtonItem.title = #"Reference";
Is this just a bug or am I missing something?
Put this in your tableviewController
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:#"Reference" style:UIBarButtonItemStylePlain target:nil action:nil];
self.navigationItem.backBarButtonItem = backButton;
Screen shot
From document
If you want to specify a custom image or title for the back button, you can assign a custom bar button item (with your custom title or image) to this property instead.
You should set it in your TableViewController, not in your WebViewContorller
Solved: I had added a grey activity indicator in a small view in the nav bar of the WVC. After I removed it, the code worked fine. Thanks #Leo, #Jacky, #Jaleel!
this work for me
self.navigationController.navigationBar.topItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Reference" style:UIBarButtonItemStylePlain target:nil action:nil];
I want to add back button on NavBar in iOS, but I can't find back array image on systemItem. Is there any property of default back arrow image.
I tried SMF.UI.iOS.BarButtonType.cancel but it has a title says "Vazgeç" instad of back arrow image.
You must assign onSelected event of back item.
Can you try this;
var leftItem = new SMF.UI.iOS.BarButtonItem({
systemItem : SMF.UI.iOS.BarButtonType.cancel,
onSelected : Pages.back()
});
this.navigationItem.leftBarButtonItems = [leftItem];
You should use Navigation Controller for that. Then the back button will appear automatically.
If you want to display only image, without text, put this code in the view controller that you came from.
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:#"" style:UIBarButtonItemStylePlain target:nil action:nil];
self.navigationItem.backBarButtonItem = backButton;
So I am just using a normal View Controller. I dragged a Navigation bar to the top and added a UIBarButtonItem with the 'pause' identifier.
I want to be able to change that identifier to the 'play' one.
Is this possible? I can't find any information on it.
I tried creating a new one, but not really sure where to go from there.
UIBarButtonItem *flipButton = [[UIBarButtonItem alloc]
initWithTitle:#"Flip"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(flipView)];
Any help would be great.
You're looking for the UIBarButtonSystemItemPlay. Just set it up, assign your selector and target, and choose which barButtonItem you want.
UIBarButtonItem *playButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemPlay target:self action:#selector(playButtonPressed:)];
self.navigationItem.rightBarButtonItem = playButton;//Or leftBarButtonItem if you want it to be on the left
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.
