UIActivityViewController make UIBarItem in inputAccessoryView disappear? - ios

I use UIToolbar as inputAccessoryView of UITextView, there are some UIBarItems inside it.
self.toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
NSMutableArray *items = [[NSMutableArray alloc] init];
UIBarButtonItem *bold = [[UIBarButtonItem alloc] initWithTitle:#"B" style:UIBarButtonItemStyleBordered target:self action:#selector(bold)];
UIBarButtonItem *italic = [[UIBarButtonItem alloc] initWithTitle:#"I" style:UIBarButtonItemStyleBordered target:self action:#selector(italic)];
UIBarButtonItem *underline = [[UIBarButtonItem alloc] initWithTitle:#"U" style:UIBarButtonItemStyleBordered target:self action:#selector(underline)];
[items addObject:underline];
[items addObject:italic];
[items addObject:bold];
self.toolbar.items = items;
[self.textView setInputAccessoryView:self.toolbar]
These items work OK, but when UIActivityViewController active, then dismiss in iOS6 simulator, these items are disappear, only blank toolbar display.
What's the reason? Please help!

How to add camera button in the keyboard to be used as a Barcode scanner in IOS?
You can use a toolbar as an accessoryview of UITextfield with UIBarButtonSystemItemCamera
toolbar = [[UIToolbar alloc] init];
toolbar.barStyle = UIBarStyleBlackOpaque;
[toolbar sizeToFit];
toolbar.frame = CGRectMake(0, 436, 320, 44);
UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
spaceItem.width = 130.0;
UIBarButtonItem *cameraItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:#selector(captureBarItemPressed:)];
NSArray *items = [NSArray arrayWithObjects: spaceItem, cameraItem, nil];
[toolbar setItems:items];
txtField.inputAccessoryView = toolbar

The action of UIBarbuttonItem on UIToolBar not called

I am having trouble as the action of UIBarbuttonItem on UIToolBar is not be called.
In the following code, although the doneBtn on toolBar is tapped, the action doneBtnAction: is not be called.
Do you have any idea to fix it?
- (void)viewDidLoad {
UIPickerView *pickerView = [[UIPickerView alloc] init];
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, -44, 320, 44)];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(doneBtnAction:)];
UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
toolBar.items = #[flex, doneBtn];
[pickerView addSubview:toolBar];
UITextField *textField = [[UITextField alloc] init];
textField.inputView = pickerView;
}
- (void)doneBtnAction:(UIBarButtonItem *)sender {
NSLog(#"%#", sender);
}
Don't add the toolbar as a subview of the picker view, especially with a negative y origin (No touches reach the toolbar because the taps are clipped to the picker view's frame).
Instead, make the toolbar the inputAccessoryView of the text field.
textField.inputAccessoryView = toolBar;
Complete code:
- (void)viewDidLoad {
UIPickerView *pickerView = [[UIPickerView alloc] init];
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(doneBtnAction:)];
UIBarButtonItem *flex = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
toolBar.items = #[flex, doneBtn];
UITextField *textField = [[UITextField alloc] init];
textField.inputView = pickerView;
textField.inputAccessoryView = toolBar;
}
One other note - Why not use the standard system Done type for the bar button item?

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];

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];

UIBarButtonItem not firing its action method

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];
