Ios 减少导航栏左侧和右侧栏按钮项的左侧和右侧空间

我在导航栏上添加了两个自定义按钮。 一个在左边，另一个在右边。 我成功地完成了它

但是我没有缩小按钮起点和框架之间的空间

我试了很多，也给出了x的负值，仍然没有帮助。 这是按钮的代码

-(void)addLeftButton
{
    UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
    aButton.backgroundColor = [UIColor redColor];
    [aButton setTitle:@"H" forState:UIControlStateNormal];
    aButton.frame = CGRectMake(0.0, 0.0, 40, 40);
    [aButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
    [aButton addTarget:self action:@selector(backBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
    [self.navigationItem setLeftBarButtonItem:aBarButtonItem];
}

-(void)addRightButton
{
    UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
    aButton.backgroundColor = [UIColor greenColor];
    [aButton setTitle:@"B" forState:UIControlStateNormal];
    aButton.frame = CGRectMake(0.0, 0.0, 40, 40);
    [aButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
    [aButton addTarget:self action:@selector(backBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
    [self.navigationItem setRightBarButtonItem:aBarButtonItem];
}

也试过用

aBarButtonItem.width = -16;

但是没有帮助

如何做到这一点。。。？ 先谢谢你

这些是我喜欢的一些链接，但没有太大帮助

像那样使用。

这里有一个Swift版本：

let negativeSpacer = UIBarButtonItem()
negativeSpacer.width = -16

let hamburgerButton = UIBarButtonItem(image: UIImage(named: "hamburgerMenu")?.withRenderingMode(.alwaysOriginal),
                                              style: .plain,
                                              target: self,
                                              action: #selector(menuButtonPressed))

navigationItem.setLeftBarButtonItems([negativeSpacer, hamburgerButton], animated: true)

你好，优素福，谢谢它的工作原理，之前我在setLeftBarButtonItems上直接添加了UIButton。现在它可以正常工作了，感谢iphone 6和6 plus，您必须使用不同的空间。@Yusufterzi，对我来说，我想在左栏按钮（后退按钮）上添加空间。我怎样才能做到这一点？我需要swift 4版本

let negativeSpacer = UIBarButtonItem()
negativeSpacer.width = -16

let hamburgerButton = UIBarButtonItem(image: UIImage(named: "hamburgerMenu")?.withRenderingMode(.alwaysOriginal),
                                              style: .plain,
                                              target: self,
                                              action: #selector(menuButtonPressed))

navigationItem.setLeftBarButtonItems([negativeSpacer, hamburgerButton], animated: true)
