如何删除 UIBarButtonItem 旁边的填充 [英] How to remove padding next to a UIBarButtonItem

问题描述

我在导航栏的自定义右侧栏按钮项中添加了一个自定义按钮，如图所示.

I have added a custom button to the navigation bar's custom right bar button item as shown in the image.

我希望能够删除按钮后的空格，使其接触屏幕的右边缘，但即使在搜索后也找不到解决方案.如果有人能提到如何，那就太好了.

I'm want to be able to remove the space after the button so that it touches the right edge of the screen but couldn't find a solution even after searching. If someone could mention how, would be great.

这是我正在使用的代码

UIButton *aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];    
aButton.frame = CGRectMake(50.0, 0.0, 60, 44);
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButton addTarget:self action:@selector(testButtonControl:) forControlEvents:UIControlEventTouchUpInside];

self.navigationItem.rightBarButtonItem = aBarButtonItem;

推荐答案

您必须创建一个新视图，添加按钮和其他所有您想要的内容，并将其添加到 titleView，如图所示.

You have to create a new view, add button and everything else you want and add it to the titleView as shown.

- (void)viewDidLoad {
    self.navigationItem.titleView = [self titleView];
}

- (UIView *)titleView {
    CGFloat navBarHeight = self.navigationController.navigationBar.frame.size.height;
    CGFloat width = 0.95 * self.view.frame.size.width;
    UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, navBarHeight)];
..
// please add what you need here
....
}
