UIBarButtonItemナビゲーションバーに2つのカスタムがUiBarButtonItem必要です。これは実際にはナビゲーションバーにある2つの組み合わせである必要があります。これらのボタンは、前のボタンと次のボタンが必要だったためにできない場合UIBarButtonItemと同様に、互いに組み合わせる必要があります。UISegmentControlUISegmentControl

したがって、のように2つのボタンを組み合わせたりカスタマイズしたりすることは可能ですかUISegmentControl。

I hope this help you..

UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
                                        [NSArray arrayWithObjects:
[NSString stringWithString:@"First"],
[NSString stringWithString:@"Second"],
nil]];


//just customize this

[segmentControl setImage:[UIImage imageNamed:@"YOUR_IMAGE1.png"] forSegmentAtIndex:0];
[segmentControl setImage:[UIImage imageNamed:@"YOUR_IMAGE2.png"] forSegmentAtIndex:1];


[segmentedControl setFrame:[self.navigationController.toolbar bounds]];

[self.navigationController.toolbar addSubview:segmentedControl];
[segmentedControl release];

それは私からの大まかな考えです..あなたがそれを実装するのに何か困難を見つけたら..私に知らせてください

次のコードは、を追加する方法を説明してUIBarButtonItemいUINavigationBarます。

あなたの場合、次のように追加 UIBarButtonItemしUIBarButtonSystemItemFlexibleSpaceますUISegmentControl.

UIToolbar *Toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    [Toolbar sizeToFit];

     NSMutableArray *barItems = [[NSMutableArray alloc] init];
    UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
    [barItems addObject:flexSpace];

    UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(Cancel)];
    [barItems addObject:btnCancel];

    UIBarButtonItem *btnDone = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(done)];
    [barItems addObject:btnDone];

    [Toolbar setItems:barItems animated:YES];

UIBarButtonItem *twoButtons = [[UIBarButtonItem alloc] initWithCustomView:Toolbar];
self.navigationItem.rightBarButtonItem = twoButtons;

//UIBarButtonItemのメソッド

-(void)Cancel
{
  // Write Code for Cancel Method
}

-(void)done
{
  // Write Code for Done Method
}

このコードを試してみてください私はしばらく前にいくつかの答えからこのコードを取得し、それを編集してアプリケーションで使用しています...これを試してください。

NSArray *segItemsArray = [NSArray arrayWithObjects: @"One", @"Two", @"Three", nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:segItemsArray];
segmentedControl.frame = CGRectMake(0, 0, 200, 30);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.selectedSegmentIndex = 0;// set your default selected button(view)

UIBarButtonItem *segmentedControlButtonItem = [[UIBarButtonItem alloc] initWithCustomView:(UIView *)segmentedControl];

UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

NSArray *barArray = [NSArray arrayWithObjects: flexibleSpace, segmentedControlButtonItem, flexibleSpace, nil];

[self setToolbarItems:barArray];
[self.navigationController setToolbarHidden:NO animated:YES];

これがお役に立てば幸いです。

これがお役に立てば幸いです。

UISegmentedControl *tabNavigation = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Previous", @"Next", nil]];
tabNavigation.segmentedControlStyle = UISegmentedControlStyleBar;
[tabNavigation setEnabled:YES forSegmentAtIndex:0];
[tabNavigation setEnabled:YES forSegmentAtIndex:1];
tabNavigation.momentary = YES;
[tabNavigation addTarget:self action:@selector(segmentedControlHandler:) forControlEvents:UIControlEventValueChanged];
UIBarButtonItem *barSegment = [[UIBarButtonItem alloc] initWithCustomView:tabNavigation];
UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

 keyboardDoneButtonView = [[UIToolbar alloc] init ];//WithFrame:CGRectMake(0, 480, 320, 44)];

 keyboardDoneButtonView.barStyle = UIBarStyleBlackTranslucent;
 keyboardDoneButtonView.translucent = YES;
 [keyboardDoneButtonView setFrame:CGRectMake(0, 480, 320, 44)];
 [keyboardDoneButtonView sizeToFit];
 [keyboardDoneButtonView setItems:[NSArray arrayWithObjects:barSegment,flexSpace,doneButton, nil]];

テキストの例：

 self.txtGivenName.inputAccessoryView=keyboardDoneButtonView;
 self.txtLastName.inputAccessoryView=keyboardDoneButtonView;



- (void)segmentedControlHandler:(id)sender
 {
if (sender){
    switch ([(UISegmentedControl *)sender selectedSegmentIndex]) {
        case 0:
        {
            [self previousClicked]; 
            break;
        }
        case 1:
        {
            [self nextClicked];
            break;
        }
        default:
            break;
    }
}

}

  -(void)previousClicked{
UIResponder* nextResponder = [sclView viewWithTag:selected-1];
if (nextResponder)
    {
    [nextResponder becomeFirstResponder];
    }

}

  -(void)nextClicked{
UIResponder* nextResponder = [sclView viewWithTag:selected+1];
if (nextResponder)
    {
    [nextResponder becomeFirstResponder];
    }

}
