UINavigationBar 中的 rightBarButtonItems 间距

发布于 2025-01-03 11:12:17 字数 109 浏览 0 评论 0原文

我正在使用 UINavigationBar 的 rightBarButtonItems 属性在导航栏的右侧添加两个按钮。是否可以使这两个按钮之间的间距更宽？

谢谢

您可以在两个按钮之间添加一个 UIBarButtonSystemItemFlexibleSpace 项。

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

You can add an UIBarButtonSystemItemFlexibleSpace item between your two buttons.

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

我无法在我的情况下获得灵活的空间，但这里是我用来定位 rightBarButtonItem 的代码：注意，我在 UIView 周围放置了边框，这样您就可以看到图像的样子在那里。

UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(89,40,100,30)];
containerView.layer.borderColor = [[UIColor redColor] CGColor];
containerView.layer.borderWidth = 1.0;
UIImage *image = [UIImage imageNamed:@"nav-icon.png"];
UIButton *navigationButton = [UIButton buttonWithType:UIButtonTypeCustom];
[navigationButton setFrame:CGRectMake(67,0,25,25)];
[navigationButton setImage:image forState:UIControlStateNormal];
[containerView addSubview:navigationButton];

UIBarButtonItem *navigationBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:containerView];

self.navigationItem.rightBarButtonItem = navigationBarButtonItem;

I was not able to get the flexible space to work in my situation but here is the code I used to be able to position the rightBarButtonItem: Note, I put a border around the UIView so you can see what it looks like with having the image in there.

UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(89,40,100,30)];
containerView.layer.borderColor = [[UIColor redColor] CGColor];
containerView.layer.borderWidth = 1.0;
UIImage *image = [UIImage imageNamed:@"nav-icon.png"];
UIButton *navigationButton = [UIButton buttonWithType:UIButtonTypeCustom];
[navigationButton setFrame:CGRectMake(67,0,25,25)];
[navigationButton setImage:image forState:UIControlStateNormal];
[containerView addSubview:navigationButton];

UIBarButtonItem *navigationBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:containerView];

self.navigationItem.rightBarButtonItem = navigationBarButtonItem;
