I have code like this in my navigation bar:
UIBarButtonItem *myButton = [[UIBarButtonItem alloc] initWithTitle:#"Next" style:UIBarButtonItemStylePlain target:self action:#selector(self)];
self.navigationItem.rightBarButtonItem = myButton;
What's the next step to grab when this is actually pressed?
You mad a mistake here by setting #selector(self).
You need to put here the actual function you need to fire:
UIBarButtonItem *myButton = [[UIBarButtonItem alloc] initWithTitle:#"Next" style:UIBarButtonItemStylePlain target:self action:#selector(doSomeThing)];
And of course:
- (void) doSomeThing{
}
Do like this
UIBarButtonItem *Button=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:#selector(myAction:)];
self.navigationItem.leftBarButtonItem=Button;
- (void)myAction:(id)sender
{
//do ur actions
}

I use the following code to setup left & right bar item,
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"nav-back"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(leftItemTapped:)];
Now it stopped working in iOS 10, the items are not "clickable"
Any one know how to fix that?
Write this code in viewWillAppear, and it should work properly...
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:YES];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"nav-back"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(leftItemTapped:)];
}
Try this code:
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:YES];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"nav-back"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(leftItemTapped:)];
}
- (IBAction)leftItemTapped:(id)sender{
NSLog(#"Navigation");
}
Output:

I am trying to call the UIBarButtonItem when the back button of that controller is pressed.This is my code.I have put the initialization in viewDidLoad and viewWillAppear but the method is not being called.
UIBarButtonItem *exampleButton = [[UIBarButtonItem alloc] initWithTitle:#" " style:UIBarButtonItemStylePlain target:self action:(#selector(backToViewController:))];
self.navigationItem.backBarButtonItem = exampleButton;
-(void)backToViewController:(UIBarButtonItem*)sender
{
[self.navigationController popToRootViewControllerAnimated:YES];
}
IT will not add backBarButtonItem with your line as :
self.navigationItem.backBarButtonItem = exampleButton;
You have to Provide leftbarbutton as
UIBarButtonItem *exampleButton = [[UIBarButtonItem alloc] initWithTitle:#" " style:UIBarButtonItemStylePlain target:self action:(#selector(backToViewController:))];
// As you are going with " ", there is no text, that means you have to click at left side randomly, to get affect.
self.navigationItem.leftBarButtonItem = exampleButton;
Update 1
You can provide Custom button with Image created by you, as you want,
UIButton *barCutomBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[barCutomBtn setImage:[UIImage imageNamed:#"backImage.png"] forState:UIControlStateNormal];
[barCutomBtn addTarget:self action:#selector(backToViewController:)forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *exampleButton = [[UIBarButtonItem alloc] initWithCustomView:barCutomBtn];
self.navigationItem.leftBarButtonItem = exampleButton;
i try to customize the name of back button item. Do you know what is the method that should be in action ?
This is the code:
UIBarButtonItem * backButton = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonItemStylePlain target:self action:??];
backButton.title = NSLocalizedString(#"backButtonNavigation", nil);
self.navigationItem.leftBarButtonItem = backButton;
Thanks in advance
I'm trying to add button to navigation bar i want to add the button without any action any help please?
UIBarButtonItem *yourButton = [[UIBarButtonItem alloc]
initWithTitle:#"Your Button"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(methodName:)];
self.navigationItem.rightBarButtonItem = yourButton;
[yourButton release];
And then method
-(IBAction)methodName {
// your code here
}
You should add UIBarButtonItem to Nav bar instead of UIButton. T do that you can call this:
UIBarButtonItem *button = [[UIBarButtonItem alloc]
initWithTitle:#"Title"
style:UIBarButtonItemStyleBordered
target:nil
action:nil];
self.navigationItem.rightBarButtonItem = button;
UIBarButtonItem *customBtn=[[UIBarButtonItem alloc] initWithTitle:#"Custom" style:UIBarButtonItemStylePlain target:self action:#selector(customBtnPressed)];
[self.navigationItem setRightBarButtonItem:customBtn];
///// called event
-(IBAction)customBtnPressed:(id)sender
{
//Your code here
}
if UIButton is you really want, try this.
UIButton *btnSample = [[UIButton alloc] initWithFrame:btnFrame];
btnSample.backgroundColor = [UIColor blueColor];
UIBarButtonItem *barBtn_cart = [[UIBarButtonItem alloc] initWithCustomView:btnSample];
self.navigationItem.rightBarButtonItem = btnSample;
I have 2 bar buttons on the tool bar , one is not working and the other is working. Some times when we touch the tip of the first bar button it will work, I think this has to be a problem with flexible space between them.
I couldn't find any possible solution, any help will be appreciated!
I'm pasting the code below
editbutton is the first button and mybutton is the second button
-(void) rightButtonToolbar:(UIBarButtonItem*)menuButton{
UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,TOOLBAR_WIDTH ,44)];
NSMutableArray *barButtons = [[NSMutableArray alloc]init];
UIBarButtonItem *flexiSpace = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[barButtons addObject:flexiSpace];
if (showEditButton)
{
NSLog(#"showeditbutton");
UIBarButtonItem *editButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:#selector(editOffer)];
[barButtons addObject:editButton];
[editButton release];
}
UIBarButtonItem *myButton2 = [[UIBarButtonItem alloc] initWithTitle:#"Kopiren" style:UIBarButtonSystemItemAction target:self action:#selector(copyOffer)];
[barButtons addObject:myButton2];
if (menuButton != nil) {
menuButtonShown=YES;
[barButtons addObject:menuButton];
}
else {
menuButtonShown=NO;
}
[toolbar setItems:barButtons animated:YES];
UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc]initWithCustomView:toolbar];
[self.navigationItem setRightBarButtonItem:rightBarButton animated:YES];
[barButtons release];
[flexiSpace release];
[rightBarButton release];
[toolbar release];
[myButton2 release];
}
