UIBarButtonItem not firing its action method - ios

In viewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
[self.navigationController setNavigationBarHidden:YES animated:NO];
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
NSMutableArray *toolBarItems = [[NSMutableArray alloc] init];
[toolBarItems addObject:[[UIBarButtonItem alloc] initWithTitle:#"Articles" style:UIBarButtonItemStyleBordered target:self action:#selector(backButtonTapped)]];
[toolBarItems addObject:[[UIBarButtonItem alloc] initWithTitle:#"Source" style:UIBarButtonItemStyleBordered target:self action:nil]];
[toolBarItems addObject:[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil]];
[toolBarItems addObject:[[UIBarButtonItem alloc] initWithTitle:#"Aa" style:UIBarButtonItemStyleBordered target:self action:nil]];
[toolBarItems addObject:[[UIBarButtonItem alloc] initWithTitle:#"Rabbit" style:UIBarButtonItemStyleBordered target:self action:nil]];
[toolBar setBackgroundImage:[[UIImage alloc] init] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];
toolBar.items = toolBarItems;
[self.view addSubview:toolBar];
Method:
- (void)backButtonTapped {
[self.navigationController popViewControllerAnimated:YES];
}
I have a breakpoint on the call inside the method but it never gets called. Why is this method never getting called?

I had a UITapGestureRecognizer on the whole view that intercepted the tap on the UIBarButton. I solved it thanks to this answer, which basically stopped the UITapGestureRecognizer from beginning unless it was outside of the UIToolBar.

Your code is not complete and I dont know if you didn't implement it or just didn't wrote it here, so just to make sure, this should work:
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
NSMutableArray *toolBarItems = [[NSMutableArray alloc] init];
[toolBarItems addObject:[[UIBarButtonItem alloc] initWithTitle:#"Articles" style:UIBarButtonItemStyleBordered target:self action:#selector(backButtonTapped)]];
toolBar.items = toolBarItems;
[self.view addSubview:toolBar];

Try like this. Its working fine.
UIToolbar *toolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 44)];
UIBarButtonItem *infoButton = [[UIBarButtonItem alloc]initWithTitle:#"back"style:UIBarButtonItemStyleBordered target:self action:#selector(backButtonTapped)];
[toolbar setItems:[NSArray arrayWithObjects:infoButton,nil]];
[self.view addSubview:toolbar];

Add a ToolBar Done Button for Picker

I am trying to add a done button on the top of the picker as follows. But unfortonately, I could not able to see done button.
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc]
initWithTitle:#"Done" style:UIBarButtonItemStyleDone
target:self action:#selector(done)];
UIToolbar *toolBar = [[UIToolbar alloc]initWithFrame:
CGRectMake(0, self.view.frame.size.height-
picker.frame.size.height-250, self.view.frame.size.width, 50)];
[toolBar setBarStyle:UIBarStyleBlackOpaque];
NSArray *toolbarItems = [NSArray arrayWithObjects:
doneButton, nil];
[toolBar setItems:toolbarItems];
categoryTF.inputView = picker;
You forgot to add your toolBar into a view. You can do that as follows:
[self.view addSubview:toolBar];
add this line:
categoryTF.inputAccessoryView = toolBar;
Use toolbar and done button for pickerView
CGRect pickerFrame = CGRectMake(0,kSCREEN_HEIGHT-200,kSCREEN_WIDTH,200);
UIPickerView * pickerview = [[UIPickerView alloc] initWithFrame:pickerFrame];
pickerview.delegate = self;
pickerview.dataSource = self;
textField.inputView=pickerview;
UIToolbar *myToolbar=[[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, kSCREEN_WIDTH, 56)];
myToolbar.barStyle=UIBarStyleBlack;
[myToolbar sizeToFit];
myToolbar.backgroundColor=[UIColor whiteColor];
NSMutableArray *barItems=[[NSMutableArray alloc]init];
UIBarButtonItem *btnItem=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
[barItems addObject:btnItem];
UIBarButtonItem *doneBtn=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(pickerDoneClicked)];
[barItems addObject:doneBtn];
[myToolbar setItems:barItems animated:YES];
myToolbar.barStyle = UIBarButtonItemStylePlain;
myToolbar.barTintColor = [UIColor colorWithRed:0.94f green:0.94f blue:0.96f alpha:1.0f];
myToolbar.tintColor=[UIColor blackColor];
txtField.inputAccessoryView=myToolbar;
-(void)pickerDoneClicked
{
[txtField resignFirstResponder];
}

Flexible bar button item now displayed on UIToolbar

I know it may seem very simple and has been asked many times but i can't get it to work .I want to add two buttons to my toolbar. One on the right side and the other one on the left. Here is the code but the flexible one which is supposed to show up on the right side doesn't appear at all. Here is the code:
toolbar = [[UIToolbar alloc] init];
toolbar.frame = CGRectMake(0, 0, self.view.frame.size.width, 44);
NSMutableArray *items = [[NSMutableArray alloc] init];
[items addObject:[[UIBarButtonItem alloc] initWithTitle:#"next" style:UIBarButtonItemStylePlain target:self action:#selector(nextResult:)]];
UIBarButtonItem *done=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:self action:#selector(showSearch:)];
[done setImage:[UIImage imageNamed:#"cancel"]];
[items addObject:done];
[toolbar setItems:items animated:NO];
You need to use UIBarButtonSystemItemFlexibleSpace instead of UIBarButtonSystemItemFixedSpace
Code:
toolbar = [[UIToolbar alloc] init];
toolbar.frame = CGRectMake(0, 0, self.view.frame.size.width, 44);
NSMutableArray *items = [[NSMutableArray alloc] init];
[items addObject:[[UIBarButtonItem alloc] initWithTitle:#"next" style:UIBarButtonItemStylePlain target:self action:#selector(nextResult:)]];
UIBarButtonItem *space = [[UIBarButtonItem alloc]initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[items addObject:space];
[items addObject:[[UIBarButtonItem alloc] initWithTitle:#"cancel" style:UIBarButtonItemStylePlain target:self action:#selector(showSearch:)]];
[toolbar setItems:items animated:NO];
Reference : UIBarButtonItem Class Reference
The item with the system item UIBarButtonSystemItemFixedSpace is a space, not button object. Therefore it does show up. It's just no button.
Change your code to
toolbar = [[UIToolbar alloc] init];
toolbar.frame = CGRectMake(0, 0, self.view.frame.size.width, 44);
NSMutableArray *items = [[NSMutableArray alloc] init];
[items addObject:[[UIBarButtonItem alloc] initWithTitle:#"next" style:UIBarButtonItemStylePlain target:self action:#selector(nextResult:)]];
UIBarButtonItem *space = [[UIBarButtonItem alloc]initWithBarButtonSystemItem: UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[items addObject:space];
[items addObject:[[UIBarButtonItem alloc] initWithTitle:#"cancel" style:UIBarButtonItemStylePlain target:self action:#selector(showSearch:)]];
[toolbar setItems:items animated:NO];

UIBarButtonItem does not respond to action event

I am using a UIToolBar and have added a UIBarButtonItem to it. When I click the button it does nothing. It does not respond to action event. This is my code :
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(x, y, width, toolBarHeight)];
[toolBar setBarStyle:UIBarStyleBlackTranslucent];
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered target:self action:#selector(changeText:)];
toolBar.items = [[NSArray alloc] initWithObjects:barButtonDone,nil];
barButtonDone.tintColor=[UIColor blackColor];
[self.view addSubview:toolBar];
Try this and see if this helps. Again your code looks fine.
// create an array for the buttons
NSMutableArray* BarbuttonsArray = [[NSMutableArray alloc] initWithCapacity:1];
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered target:self action:#selector(changeText:)];
barButtonDone.style = UIBarButtonItemStyleBordered;
[BarbuttonsArray addObject:barButtonDone];
[toolbar setItems:BarbuttonsArray animated:YES];
I literally copied and pasted your code into a test project of mine and this is what I get. The only change I did was the method name
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
[toolBar setBarStyle:UIBarStyleDefault];
UIBarButtonItem *barButtonDone = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered target:self action:#selector(changeText)];
toolBar.items = [[NSArray alloc] initWithObjects:barButtonDone,nil];
barButtonDone.tintColor=[UIColor blackColor];
[self.view addSubview:toolBar];
}
-(IBAction) changeText
{
NSLog(#"changeText ...");
}

UITextField delegate causes UIToolBar not show in iOS

This is what I am doing to display a UIToolbar in a UITextField's acceccory view.. Unfortunately I am not able to see it for some reason. What am I doing wrong here?
UIBarButtonItem *flexiableItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(doneTyping)];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithTitle:#"Next" style:UIBarButtonItemStyleBordered
target:self action:#selector(gotoNextTextfield:)];
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
NSArray *items = [NSArray arrayWithObjects:item2, flexiableItem, item1, nil];
toolbar.items = items;
[inputAccView addSubview:toolbar];
[self.msgTextField setInputAccessoryView:inputAccView];
Update:
if I remove self.msgTextField.delegate = self; then I can see the toolbar.. but why??
Try replacing
[inputAccView addSubview:toolbar];
[self.msgTextField setInputAccessoryView:inputAccView];
with
[self.msgTextField setInputAccessoryView:toolbar];
In your .h file add <UITextFieldDelegate>
Then in your - (void)viewDidLoad try This, it works fine for me:
// Keyboard Tool Bar
UIToolbar *toolbar = [[UIToolbar alloc] init];
[toolbar setBarStyle:UIBarStyleBlackTranslucent];
[toolbar sizeToFit];
UIBarButtonItem *nextField =[[UIBarButtonItem alloc] initWithTitle:#"Next" style:UIBarButtonItemStyleBordered target:self action:#selector(nextField)];
UIBarButtonItem *flexButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
UIBarButtonItem *doneButton =[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(resignKeyboard)];
NSArray *itemsArray = [NSArray arrayWithObjects: nextField, flexButton, doneButton, nil];
[toolbar setItems:itemsArray];
[self.msgTextField setInputAccessoryView:toolbar];

cancel button appears but done button does not appear in uitoolbar

I have written the code below to display the datepicker in popover along uitoolbar.
I can see the cancel button but not the Done button.
If I remove the code for flexspace then done button appears but I need the done button to be on the extreme right positon but it stands next to cancel button.
How can I fix this ? Thanks in Advance.
UIViewController* popoverContent = [[UIViewController alloc] init]; //ViewController
UIView *popoverView = [[UIView alloc] init]; //view
popoverView.backgroundColor = [UIColor blackColor];
datePicker=[[UIDatePicker alloc]init];//Date picker
datePicker.frame=CGRectMake(0,44,320, 216);
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker setMinuteInterval:5];
[datePicker setTag:10];
[datePicker addTarget:self action:#selector(Result) forControlEvents:UIControlEventValueChanged];
[popoverView addSubview:datePicker];
popoverContent.view = popoverView;
popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
popoverController.delegate=self;
[popoverController setPopoverContentSize:CGSizeMake(320, 264) animated:NO];
[popoverController presentPopoverFromRect:self.uitext.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];//tempButton.frame where you need you can put that frame
// UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,320,40)];
// [pickerToolbar sizeToFit];
// pickerToolbar.barStyle = UIBarStyleBlackTranslucent;
// NSMutableArray *barItems = [[NSMutableArray alloc] init];
//
// UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonSystemItemCancel target:self action:#selector(cancel_clicked:)];
// [barItems addObject:cancelBtn];
//
// UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
// [barItems addObject:flexSpace];
//
// UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(done_clicked:)];
// [barItems addObject:doneBtn];
//
//
//
// [pickerToolbar setItems:barItems animated:YES];
//
// UIPickerView *picker = [[UIPickerView alloc] init];
// picker.frame = CGRectMake(0, 44, 320, 216);
// picker.delegate = self;
// picker.dataSource = self;
// picker.showsSelectionIndicator = YES;
// [actionSheet addSubview:picker];
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,self.view.bounds.size.width,40)];
[pickerToolbar sizeToFit];
pickerToolbar.barStyle = UIBarStyleBlackTranslucent;
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonSystemItemCancel target:self action:#selector(cancel_clicked:)];
[barItems addObject:cancelBtn];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(done_clicked:)];
[barItems addObject:doneBtn];
[pickerToolbar setItems:barItems animated:YES];
[popoverView addSubview:pickerToolbar];
[self.uitext resignFirstResponder];
Try this code :-
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,self.view.bounds.size.width,40)];
[pickerToolbar sizeToFit];
pickerToolbar.barStyle = UIBarStyleBlackTranslucent;
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonSystemItemCancel target:self action:#selector(cancel_clicked:)];
[barItems addObject:cancelBtn];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(done_clicked:)];
[barItems addObject:doneBtn];
[pickerToolbar setItems:barItems animated:YES];
[popoverView addSubview:pickerToolbar];
Hope it helps you..
EDIT :-
Add this line below [pickerToolbar setItems:barItems animated:YES]; :-
pickerToolbar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;
and comment [pickerToolbar sizeToFit]; line
So your code will be
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,self.view.bounds.size.width,44.0)];
//[pickerToolbar sizeToFit];
pickerToolbar.barStyle = UIBarStyleBlackTranslucent;
NSMutableArray *barItems = [[NSMutableArray alloc] init];
UIBarButtonItem *cancelBtn = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonSystemItemCancel target:self action:#selector(cancel_clicked:)];
[barItems addObject:cancelBtn];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[barItems addObject:flexSpace];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(done_clicked:)];
[barItems addObject:doneBtn];
[pickerToolbar setItems:barItems animated:YES];
pickerToolbar.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin;
[popoverView addSubview:pickerToolbar];
