Can I change the position of navigationbar item?
提问by u1053236
Here is the snapshot:
这是快照：
And the code is here:
代码在这里：
UIButton *leftButton = [UIButton buttonWithType:UIButtonTypeCustom];
leftButton.frame = CGRectMake(0.0f, 0.0f, 46.0f, 32.0f);
[leftButton setBackgroundImage:[UIImage imageNamed:@"navi_register_up.png"] forState:UIControlStateNormal];
[leftButton addTarget:self action:@selector(doRegister) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *leftBarItem = [[UIBarButtonItem alloc] initWithCustomView:leftButton];
self.navigationItem.leftBarButtonItem = leftBarItem;
[leftBarItem release];
Is there any way to move the button up some px? Thank you:)
有没有办法将按钮向上移动一些像素？谢谢：）

You need to create a UIBarButtonItemwith system item UIBarButtonSystemItemFixedSpacewith -5 width which will remove 5 pxpadding. Then set leftBarButtonItemswith both fixed space item and your back bar item like this -
您需要创建一个宽度为 -5 的UIBarButtonItem系统项UIBarButtonSystemItemFixedSpace，这将删除5 px填充。然后像这样设置leftBarButtonItems固定空间项目和你的后栏项目 -
UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
[negativeSpacer setWidth:-5];
self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:negativeSpacer,leftBarItem,nil];

You can try this,
你可以试试这个
leftButton.imageEdgeInsets = UIEdgeInsetsMake(-2, 0, 0, 0);

Add a UIBarButtonSystemItemFlexibleSpaceitem in between the items you want to separate.
UIBarButtonSystemItemFlexibleSpace在要分开的项目之间添加一个项目。

Here's a Swift 3 version of the most voted answer:
这是投票最多的答案的 Swift 3 版本：
let soundButton = UIBarButtonItem(image:image , style: UIBarButtonItemStyle.plain, target: self, action: #selector(self.soundPressed))
let negativeSpacer = UIBarButtonItem(barButtonSystemItem: .fixedSpace, target: nil, action: nil)
negativeSpacer.width = -5
self.navigationItem.rightBarButtonItems = [negativeSpacer,soundButton]

The height of a standard bar button is 29pt. Do yourself a favor and just shrink leftbutton's height and navi_register_up.png's height instead.
标准条形按钮的高度为 29pt。帮自己一个忙，只是缩小leftbutton的高度 和navi_register_up.png的高度。

You can use this code,I think this will be helpful to you. UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0,0,50,32); [button setBackgroundImage:[UIImage imageNamed:@"btn_back.png"] forState:UIControlStateNormal];
您可以使用此代码，我认为这会对您有所帮助。UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0,0,50,32); [button setBackgroundImage:[UIImage imageNamed:@"btn_back.png"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(BackBtnClicked) forControlEvents:UIControlEventTouchUpInside];
UIView *backButtonView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 50, 32)];
backButtonView.bounds = CGRectOffset(backButtonView.bounds, -1, -4);
[backButtonView addSubview:button];
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButtonView];
//barButtonItem.imageInsets = UIEdgeInsetsMake(-6, 20, 30, 0);
[self.navigationItem setLeftBarButtonItem:barButtonItem];

I had a similar issue and found an option that sufficed in the storyboard. Just click on the navbar item and you should see the x/y position options.
我有一个类似的问题，并在故事板中找到了一个足够的选项。只需单击导航栏项目，您就会看到 x/y 位置选项。
