Toolbar item not showing - iphone

Not sure what I'm doing wrong. I don't have a nib so I'm making everything in loadView. The toolbar shows up but the segmentedControl does not.
- (void)loadView
{
// Toolbar
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 90)];
[toolbar setTintColor:[UIColor lightGrayColor]];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithFrame:CGRectMake(10, 10, 200, 30)];
[segmentedControl setSegmentedControlStyle:UISegmentedControlStyleBar];
UIBarButtonItem *item = [[[UIBarButtonItem alloc] initWithCustomView:segmentedControl] autorelease];
NSArray *toolbarItems = [NSArray arrayWithObjects:item, nil];
[toolbar setItems:toolbarItems animated:NO];
[self.view addSubview:toolbar];
}

Write below code in place of your code; this will help you to add segment control to your toolbar:
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 90)];
[toolbar setTintColor:[UIColor lightGrayColor]];
CGRect frame;
frame.origin.x = 10;
frame.origin.y = 10;
frame.size.width = 200;
frame.size.height = 30;
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"Hello",#"Hi", nil]];
[segmentedControl setSegmentedControlStyle:UISegmentedControlStyleBar];
segmentedControl.tintColor = [UIColor blackColor];
segmentedControl.frame = frame;
[toolbar addSubview:segmentedControl];
[self.view addSubview:toolbar];

You've got to add it as a subview of the view as you did with the toolbar. I.e:
[self.view addSubview:segmentedControl];
It should work.
Cheers

How to create this toolbar programmatically [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.
Closed 10 years ago.
I am really having a hard time creating a UIToolBar programmatically(no xib file). This is what I would like to create.
But till now, I feel I have not approached it in the right way. I have tried adding a barbuttonitem to it, but I cant create the effect as shown in the png. How should I go about it. Help needed.
Edit: I have added a bigger image
UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[self.navigationController.toolbar setBarStyle:UIBarStyleBlackOpaque];
UIBarButtonItem *customItem = [[UIBarButtonItem alloc] initWithTitle:#"toolbar title" style:UIBarButtonItemStylePlain target:self action:#selector(onToolbarTapped:)];
NSArray *toolbarItems = [NSArray arrayWithObjects:spaceItem, customItem, spaceItem, nil];
[self setToolbarItems:toolbarItems animated:NO];
Create your toolbar with CGRECT to put it where you want
UIToolbar *myToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(x, y, width, height)];
You can customize it with background image, title, text color, background color, ...
Next create your button
UIBarButtonItem *theButton = [UIBarButtonItem alloc] initWithTitle:#"button title" style:UIBarButtonItemStylePlain target:self action:#selector(selector:)];
Add it to yout toolbar :
NSArray *buttons = [NSArray arrayWithObjects: theButton, nil];
[myToolbar setItems:buttons animated:NO]
add your toolbar to the current view
[self.view addSubview:mytoolbar]
Just typed not tested, hope it'll help
ToolBar and buttons have custom images
- (void)viewDidLoad {
[super viewDidLoad];
UIToolbar *myToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height - 44, 320, 44)];
[myToolbar insertSubview:[[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"toolbar_40.png"]] autorelease] atIndex:0];
UIBarButtonItem *barButtonDone = [self createImageButtonItemWithNoTitle:#"button_down.png" target:self action:#selector(closeMe:)];
UIBarButtonItem *barButtonShare = [self createImageButtonItemWithNoTitle:#"button_share.png" target:self action:#selector(actionShareButton:)];
UIBarButtonItem *barButtonFlexibleGap = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]autorelease];
myToolbar.items = [NSArray arrayWithObjects:barButtonDone,barButtonFlexibleGap,barButtonShare,nil];
[self.view addSubview:myToolbar];
[myToolbar release];
}
-(void)closeMe:(id)sender
{
NSLog(#"closeMe");
}
-(void)actionShareButton:(id)sender
{
NSLog(#"actionShareButton");
}
-(UIBarButtonItem *)createImageButtonItemWithNoTitle:(NSString *)imagePath target:(id)tgt action:(SEL)a

UIImage *buttonImage = [[UIImage imageNamed:#"button_slice.png"] stretchableImageWithLeftCapWidth:5 topCapHeight:0];
UIImage *buttonPressedImage = [[UIImage imageNamed:#"button_slice_over.png"] stretchableImageWithLeftCapWidth:5 topCapHeight:0];
CGRect buttonFrame = [button frame];
buttonFrame.size.width = 32;
buttonFrame.size.height = 32;
[button setFrame:buttonFrame];
UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 32, 32)];
imageView.image = [UIImage imageNamed:imagePath];
[button addSubview:imageView];
[imageView release];
[button setBackgroundImage:buttonImage forState:UIControlStateNormal];
[button setBackgroundImage:buttonPressedImage forState:UIControlStateHighlighted];
[button addTarget:tgt action:a forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *buttonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
return [buttonItem autorelease];
}
These png files need to be added
toolbar_40.png for toolbar image
button_down.png for button image
button_share.png for button image
button_slice.png for button background
button_slice_over.png for button background (pressed)
UIToolbar *toolbar = [UIToolbar new];
toolbar.barStyle = UIBarStyleBlackTranslucent;
toolbar.backgroundColor = [UIColor clearColor];
Then add a UIBarButtonItem to toolbar.
UIToolbar *myToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height - 44, 320, 44)];
myToolbar.barStyle = UIBarStyleBlack;
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
myLabel.text = #"Sperre aufheben";
myLabel.textColor = [UIColor whiteColor];
myLabel.textAlignment = UITextAlignmentCenter;
myLabel.backgroundColor = [UIColor clearColor];
[myToolbar addSubview:myLabel];
[self.view addSubview:myToolbar];
[myLabel release];
[myToolbar release];
Seems like a better fit for a nav bar (at least if you are keeping with the spirit of what you are doing: IE adding a title to the bottom of the screen)
Anyway I created a simple test project and this is what I did to get the functionality pictured, you may have to insert it into the view/controller differently but it gets what you want relatively easy and doesn't use the button bar
- (void)viewDidLoad {
[super viewDidLoad];
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height - 44, 320, 44)];
[navBar setBarStyle:UIBarStyleBlack];
UINavigationItem *title = [[UINavigationItem alloc] initWithTitle:#"Your Title"];
NSArray *array = [[NSArray alloc] initWithObjects:title, nil];
[navBar setItems:array];
[self.view addSubview:navBar];
}

How to add multiple controls in navigationbar?

I want to insert one button and one label in my NavigationBar in iOS.
I have tried with UISegmentedControl and it works completely fine with one control!
Now the problem is I want to add multiple controls as i have said before How can I?
Look at my code
UIView *v;
[v insertSubview:listingsLabel atIndex:0];
[v insertSubview:shareBtn atIndex:1];
[v setFrame:[self.navigationController.toolbar bounds]];
self.navigationItem.titleView = v;
v.frame = CGRectMake(0, 0, 200, 29);
and it gives me error of EXC_BAD_ACCESS
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 44.01)];
// create the array to hold the buttons, which then gets added to the toolbar
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];
// create a standard "add" button
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray array]];
[segmentedControl insertSegmentWithTitle:#"All" atIndex:0 animated:NO];
[segmentedControl insertSegmentWithTitle:#"Related" atIndex:1 animated:NO];
segmentedControl.selectedSegmentIndex = 0;
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
[segmentedControl addTarget:self action:#selector(segmentedAction:) forControlEvents:UIControlEventValueChanged];
// create a standard "add" button
UIBarButtonItem* bi = [[UIBarButtonItem alloc] initWithCustomView: segmentedControl];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// create a spacer
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
[buttons addObject:bi];
[bi release];
// create a standard "refresh" button
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemSave target:self action:#selector(save:)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// stick the buttons in the toolbar
[tools setItems:buttons animated:NO];
[buttons release];
// and put the toolbar in the nav bar
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
Because you don't init the UIView the right way, it crashes because the iPhone doesn't know what to do with
[v insertSubview:listingsLabel atIndex:0];
This is because v isn't an object yet. So change
UIView *v;
to
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 29)];
And release it here again (if not using arc)
self.navigationItem.titleView = v;
[v release];
The navigation bar on iPhone only supports only a left and right bar button item, and a title view. Only the (larger) navigation bar on iPad allows an arbitrary number of buttons.
If you're using a navigation bar without a navigation controller, I suppose you could just plop whatever you want onto it as subviews.
UIButton *btnBack = [[UIButton alloc]initWithFrame:CGRectMake(5,5,60,32)];
[btnBack setBackgroundImage:[UIImage imageNamed:#"back_btn.png"] forState:UIControlStateNormal];
btnBack.backgroundColor = [UIColor clearColor];
[btnBack addTarget:self action:#selector(eventBack:) forControlEvents:UIControlEventTouchUpInside];
UILabel *lbl = [[UILabel alloc]initWithFrame:CGRectMake(12, 2, 60,25)];
[lbl setBackgroundColor:[UIColor clearColor]];
lbl.font = [UIFont fontWithName:#"Helvetica" size:12];
lbl.font = [UIFont boldSystemFontOfSize:12];
lbl.textColor = [UIColor whiteColor];
lbl.text =#" Back";
[btnBack addSubview:lbl];
[lbl release];
UIBarButtonItem *backBarBtn = [[UIBarButtonItem alloc] initWithCustomView:btnBack];
self.navigationItem.leftBarButtonItem = backBarBtn;
[btnBack release];
[backBarBtn release];
UILabel *lblTitle = [[UILabel alloc] initWithFrame:CGRectMake(110, 0, 170, 40)];
lblTitle.text = #"ABC";
lblTitle.backgroundColor = [UIColor clearColor];
lblTitle.textColor = [UIColor whiteColor];
lblTitle.textAlignment = UITextAlignmentCenter;
lblTitle.font = [UIFont fontWithName:#"Helvetica" size:17];
lblTitle.font = [UIFont boldSystemFontOfSize:17];
self.navigationItem.titleView = lblTitle;
[lblTitle release];

UISegmentedCotrol Hidden

I created a UISegmentedControl through the following snippet.
NSArray *itemArray = [NSArray arrayWithObjects: #"One", #"Two", nil];
segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(105, 270, 140, 30);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.selectedSegmentIndex = 0;
[segmentedControl addTarget:self action:#selector(selectWeek:) forControlEvents:UIControlEventValueChanged];
[self.navigationController.view addSubview:segmentedControl];
When I press the button to turn UISegmentedCotrol, it doesn't work. What could be wrong?
I'm doing segmentedControl.hidden = YES;.
[self.navigationController.view addSubview:segmentedControl];
change it to
[self.view addSubview:segmentedControl];
and make sure segmentedControl.hidden=NO; when you add it to subview;

}
You should definitely NOT use UIActionSheet to hold an UIDatePicker because this functionality is deprecated!
From the Documentation:
Subclassing Notes
UIActionSheet is not designed to be subclassed, nor should you add
views to its hierarchy. If you need to present a sheet with more
customization than provided by the UIActionSheet API, you can create
your own and present it modally with
presentViewController:animated:completion:.
and
Important: UIActionSheet is deprecated in iOS 8. (Note that
UIActionSheetDelegate is also deprecated.) To create and manage action
sheets in iOS 8 and later, instead use UIAlertController with a
preferredStyle of UIAlertControllerStyleActionSheet.
What you could very easily do is to create an UIView to hold the UIDatePicker and animate the view as appropriate. You can even add an UIToolbar to it if you need to.
Here's an example:
Create two properties:
#property (strong, nonatomic) UIDatePicker *theDatePicker;
#property (strong, nonatomic) UIView *pickerView;
Create your picker, embed it into the UIView and show:
-(void) createDatePickerAndShow {
UIToolbar *controlToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, pickerView.bounds.size.width, 44)];
[controlToolbar sizeToFit];
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *setButton = [[UIBarButtonItem alloc] initWithTitle:#"Set" style:UIBarButtonItemStyleDone target:self action:#selector(dismissDateSet)];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleBordered target:self action:#selector(cancelDateSet)];
[controlToolbar setItems:[NSArray arrayWithObjects:spacer, cancelButton, setButton, nil] animated:NO];
[theDatePicker setFrame:CGRectMake(0, controlToolbar.frame.size.height - 15, theDatePicker.frame.size.width, theDatePicker.frame.size.height)];
if (!pickerView) {
pickerView = [[UIView alloc] initWithFrame:theDatePicker.frame];
} else {
[pickerView setHidden:NO];
}
CGFloat pickerViewYpositionHidden = self.view.frame.size.height + pickerView.frame.size.height;
CGFloat pickerViewYposition = self.view.frame.size.height - pickerView.frame.size.height;
[pickerView setFrame:CGRectMake(pickerView.frame.origin.x,
pickerViewYpositionHidden,
pickerView.frame.size.width,
pickerView.frame.size.height)];
[pickerView setBackgroundColor:[UIColor whiteColor]];
[pickerView addSubview:controlToolbar];
[pickerView addSubview:theDatePicker];
[theDatePicker setHidden:NO];
[self.view addSubview:pickerView];
[UIView animateWithDuration:0.5f
animations:^{
[pickerView setFrame:CGRectMake(pickerView.frame.origin.x,
pickerViewYposition,
pickerView.frame.size.width,
pickerView.frame.size.height)];
}
completion:nil];
}
And to dismiss the DatePicker:
-(void) cancelDateSet {
CGFloat pickerViewYpositionHidden = self.view.frame.size.height + pickerView.frame.size.height;
[UIView animateWithDuration:0.5f
animations:^{
[pickerView setFrame:CGRectMake(pickerView.frame.origin.x,
pickerViewYpositionHidden,
pickerView.frame.size.width,
pickerView.frame.size.height)];
}
completion:nil];
}
self.view.userInteractionEnabled = NO;
self.blurView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.blurView setBackgroundColor:[UIColor lightGrayColor]];
[self.blurView setAlpha:0.3];
[[[UIApplication sharedApplication] delegate].window addSubview:self.blurView];
CGRect pickerFrame = CGRectMake(0, 40, 0, 0);
UIDatePicker *pickerView = [[UIDatePicker alloc] initWithFrame:pickerFrame];
pickerView.datePickerMode = UIDatePickerModeDate;
[pickerView setBackgroundColor:[UIColor whiteColor]];
[pickerView addTarget:self action:#selector(pickerChanged:) forControlEvents:UIControlEventValueChanged];
__block CGRect frame = CGRectMake(0, [[UIScreen mainScreen] bounds].size.height, [[UIScreen mainScreen] bounds].size.width, 220);
self.viewForPicker = [[UIView alloc] initWithFrame:frame];
[self.viewForPicker setBackgroundColor:[UIColor whiteColor]];
[self.viewForPicker addSubview:pickerView];
[[[[UIApplication sharedApplication] delegate] window] addSubview:self.viewForPicker];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setTitleColor:[UIColor lightGrayColor] forState:UIControlStateHighlighted];
[button setTitle:#"Done" forState:UIControlStateNormal];
[button addTarget:self action:#selector(doneButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(250, 15, 60, 30)];
[button.layer setCornerRadius:5.0];
[button.layer setBorderWidth:1.0];
[button.layer setBorderColor:[[IMAppStyle appColor] CGColor]];
[self.viewForPicker addSubview:button];
[self.viewForPicker.layer setCornerRadius:8.0];
float animationDuration = 0.25;
[UIView animateWithDuration:animationDuration animations:^{
frame.origin.y -= (180+40+35);
[self.viewForPicker setFrame:frame];
}];

Selector of one item of UIToolbar doesn't work

read the following code:
// Creiamo la toolbar sotto
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 372, 320, 44)];
toolbar.tintColor = [UIColor blackColor];
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"imgImpostazioniToolbar.png"]];
UIBarButtonItem *pulsanteImpostazioni = [[UIBarButtonItem alloc] initWithCustomView:imageView];
[pulsanteImpostazioni setTarget:self];
[pulsanteImpostazioni setAction:#selector(prova)];
[imageView release];
UIBarButtonItem *spaziatore = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
NSArray *buttons = [[NSArray alloc] initWithObjects:spaziatore, pulsanteImpostazioni, spaziatore, nil];
[toolbar setItems:buttons animated:NO];
[self.view addSubview:toolbar];
[buttons release];
I can see correctly my image but when I try to touch it nothing happen.
I didn't set correctly the selector of "pulsanteImpostazioni"?
Thanks
P.s. "prova" contain only a NSLog.
Try
[pulsanteImpostazioni setAction:#selector(prova:)];
The colon at the end of the selector name matters.
i find the solution in this mode:
UIButton *pulsanteImpostazioni = [UIButton buttonWithType:UIButtonTypeCustom];
[pulsanteImpostazioni setFrame:CGRectMake(0, 0, 200, 50)];
[pulsanteImpostazioni setImage:[UIImage imageNamed:#"imgImpostazioniToolbar.png"] forState:UIControlStateNormal];
[pulsanteImpostazioni addTarget:self action:#selector(prova) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *pulsanteImpostazioni = [[UIBarButtonItem alloc] initWithCustomView:pulsanteImpostazioni];
Thanks anyway for your answers =)
