UIToolbarの右側にUIBarButtonItemを配置するにはどうすればよいですか？

Question

InterfaceBuilderにモーダルで表示されるツールバーを備えたビューを設計しました。左側にあるUIBarButtonItemをツールバーの右側に表示したいと思います。これをIBで、またはコードを介してどのように実行できますか？

Answer 1

誰かがこの投稿に出くわした場合、コードでそれを行う方法は次のとおりです。

UIBarButtonItem *leftButton = [[[UIBarButtonItem alloc] initWithTitle:@"Item" style:UIBarButtonItemStyleBordered target:self action:@selector(btnItem1Pressed:)] autorelease];

UIBarButtonItem *flex = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil] autorelease];

UIBarButtonItem *rightButton = [[[UIBarButtonItem alloc] initWithTitle:@"Item" style:UIBarButtonItemStyleBordered target:self action:@selector(btnItem2Pressed:)] autorelease];


self.toolbarItems = [NSArray arrayWithObjects: leftButton, flex, rightButton, nil];

Answer 2

「フレキシブルスペース」という識別子を持つアイテムを挿入します。

-このように右に1項目

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

UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithTitle:@"item1” style:UIBarButtonItemStylePlain target:self action:nil];

self.toolbarItems = [NSArray arrayWithObjects: flexible, item1, nil];

-このように左右に2つのアイテム

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

UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithTitle:@"item1” style:UIBarButtonItemStylePlain target:self action:nil];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithTitle:@"item2” style:UIBarButtonItemStylePlain target:self action:nil];

self.toolbarItems = [NSArray arrayWithObjects: item1, flexible, item2, nil];

-このような3つのアイテム

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

UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithTitle:@"item1” style:UIBarButtonItemStylePlain target:self action:nil];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithTitle:@"item2” style:UIBarButtonItemStylePlain target:self action:nil];
UIBarButtonItem *item3 = [[UIBarButtonItem alloc] initWithTitle:@"item3” style:UIBarButtonItemStylePlain target:self action:nil];

self.toolbarItems = [NSArray arrayWithObjects: item1, flexible, item2, flexible, item3, nil];

-このような4つのアイテム

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

UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithTitle:@"item1” style:UIBarButtonItemStylePlain target:self action:nil];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithTitle:@"item2” style:UIBarButtonItemStylePlain target:self action:nil];
UIBarButtonItem *item3 = [[UIBarButtonItem alloc] initWithTitle:@"item3” style:UIBarButtonItemStylePlain target:self action:nil];
UIBarButtonItem *item4 = [[UIBarButtonItem alloc] initWithTitle:@"item4” style:UIBarButtonItemStylePlain target:self action:nil];

self.toolbarItems = [NSArray arrayWithObjects: item1, flexible, item2, item3, flexible, item4, nil];

スペースを追加する場合は、フレキシブルバーボタンを追加する必要があります。

スウィフトコード：

func addDoneButton() -> UIToolbar {
    let toolbar = UIToolbar()
    let flexButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
    let doneButton = UIBarButtonItem(title: "Done", style: .Plain, target: self, action: Selector("donePressed"))
    toolbar.setItems([flexButton, doneButton], animated: true)
    toolbar.sizeToFit()
    return toolbar
}

Answer 5

Swift 3.x以降：

internal var textFieldHandlerToolBar: UIToolbar = {
        let tb = UIToolbar.init(frame: CGRect.init(Origin: .zero, size: CGSize.init(width: UIScreen.screenSize().width, height: 44.0)))
        let flexibleButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil)
        let doneBarButton = UIBarButtonItem.init(title: "Done", style: UIBarButtonItemStyle.done, target: self, action: #selector(actionDonePickerSelection))
        tb.setItems([flexibleButton, doneBarButton], animated: false)
        return tb
    }()
