Hello everybody)I have a button(from image) on Navigation bar:

UIImage *imageArrow = [UIImage imageNamed: @"white_arrow_down.png"];
UIButton *infoButton=[UIButton buttonWithType:UIButtonTypeCustom];
[infoButton setImage:imageArrow forState:UIControlStateNormal];
CGRect viewRectArrow = CGRectMake(0, 0, 15, 17);
infoButton.frame=viewRectArrow;
[infoButton addTarget:self action:@selector(callToolbarClick forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *infoBarButtonItem= [[[UIBarButtonItem alloc] initWithCustomView:infoButton] autorelease];
self.navigationItem.leftBarButtonItem = infoBarButtonItem;


I have a -(void) :
-(void) callToolbarClick: sender {


toolbar = [UIToolbar new];
toolbar.barStyle = UIBarStyleDefault;




// size up the toolbar and set its frame
[toolbar sizeToFit];
CGFloat toolbarHeight = [toolbar frame].size.height;
CGRect mainViewBounds = self.view.bounds;
[toolbar setFrame:CGRectMake(CGRectGetMinX(mainViewBounds),
CGRectGetMinY(mainViewBounds) + CGRectGetHeight(mainViewBounds) - (toolbarHeight * 2.0) -280,
CGRectGetWidth(mainViewBounds),
toolbarHeight)];


[self.view addSubview:toolbar];

currentSystemItem = UIBarButtonSystemItemDone;
[self toolbarItems ];

Please Help me!How can I do that after the second pressing toolbar disappear?thanks in advance

Could you clarify the problem?
You want the second toolbar to disappear?
The second toolbar is disappearing?

The way I do toolbars is, but I do not know if this helps.

// ---- TOOLBAR -----------//


UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100.0, 44.01f)];
//[toolbar setBackgroundColor:[UIColor blackColor]];
//[toolbar setTintColor:[UIColor redColor]];
//[toolbar.layer setBorderColor:[[UIColor redColor] CGColor]];

// Bar buttons

UIBarButtonItem *barReloadBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(btnReload:)];

[barReloadBtn setStyle:UIBarButtonItemStyleBordered];

// Profile bar button
UIImage *image = [[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"19-gear" ofType:@"png"]];

UIBarButtonItem *barProfileBtn = [[UIBarButtonItem alloc] initWithImage:image style:UIBarButtonItemStyleBordered target:self action:@selector(btnProfile:)];

[image release];

// Button array

NSMutableArray *buttons = [[NSMutableArray alloc] init]; 

[buttons addObject:barProfileBtn];
[buttons addObject:barReloadBtn];


[toolbar setItems:buttons];

// Set nav items
UIBarButtonItem *barBtnItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar];


self.navigationItem.rightBarButtonItem = barBtnItem;

// memory cleanup
[barBtnItem release];
[buttons release];
[barReloadBtn release];
[barProfileBtn release];	
[toolbar release];

// ---- /TOOLBAR -----------//

Hi)No.First pressing causes the toolbar appears under the navigation bar (like drop down window). I need that would be if you press it was hiding.Thx =)

[albertwesker]

Thanks dude i am also facing similar problem and now it perfectly works for me............

[GraceWitch]

What a problem?Like my or not?If you know how to help me to fix this problem-tell me pls )

[GraceWitch]

I know how to enter a boolean but how to do it .... who knows please tell me. It is very necessary...

[GraceWitch]

my bar is created and show on display after clicking on the button. I would do that if you press the same button on the bar disappear and(or?) hiding ... That's the gist of my question)

Can you post an image of what the problem is, and what you are trying to acheive (even if its a mockup).

Thanks.

So if I understand correctly, you want to be able to show and hide the toolbar when clicking the same button?

Create a BOOL to track if it's showing, create the toolbar once, and then you can either add it to the view or remove it...

You'll need to keep the toolbar as a property of the viewcontroller though and not a method variable that disappears when the method is done...

This is rough - not knowing more about your code, but trying something like...

In your view controller .h:

BOOL    showingToolbar;
UIToolbar    *myToolbar;

Then in your .m file...

-(void) callToolbarClick: sender
{
    if (!myToolbar)
    {
        // create the toolbar - but DO NOT add it to the view
    }

    if (showingToolbar)
        [myToolBar removeFromSuperview];
    else
        [self.view addSubview:myToolBar];

    showingToolbar = !showingToolbar;
}

Also - don't forget to

    if (myToolbar)
        [myToolbar release];

in your -(void) dealloc routine...

Or - you could create the myToolBar object in your viewDidLoad routine and then not worry about building it on the fly when the button is pressed... a bunch of options here...

Hope this helps...
