How to create this toolbar programmatically [closed]

问题

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

回答1:

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];

回答2:

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
{
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

    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)

回答4:

UIToolbar *toolbar = [UIToolbar new];
toolbar.barStyle = UIBarStyleBlackTranslucent;
toolbar.backgroundColor = [UIColor clearColor];

Then add a UIBarButtonItem to toolbar.

回答5:

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];
}
