将位置更改为更靠近 UINavigationBar 中 rightBarButtonItem 的右侧 [英] Change position closer to the right of rightBarButtonItem in UINavigationBar

问题描述

这是我的代码

- (void)createCustomBtnRightBar:(UIImage *)buttonImage{self.navigationItem.rightBarButtonItem = nil;UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];如果(按钮图像！= nil){[button setImage:buttonImage forState:UIControlStateNormal];button.frame = CGRectMake(0, 0, 45, 33);button.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 0, -10);} 别的 {[button setTitle:@"Add New Pal" forState:UIControlStateNormal];button.frame = CGRectMake(0, 0, 110, 24);[button.titleLabel setTextAlignment:NSTextAlignmentRight];}[button addTarget:self action:@selector(onClickBtnSendClip:) forControlEvents:UIControlEventTouchUpInside];[按钮 setBackgroundColor:[UIColor greenColor]];//创建一个 UIBarButtonItem 与按钮作为自定义视图UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];self.navigationItem.rightBarButtonItem = customBarItem;}

将宽度更改为 200 时

当添加button.titleEdgeInsets = UIEdgeInsetsMake(0, 20, 0, 0);

在所有这些情况下，右边的区域都不能移动

我需要这样的东西.

我什至试过这个

UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];customBarItem.customView = 按钮；

但是会崩溃

*** 由于未捕获的异常NSInvalidArgumentException"而终止应用程序，原因:固定和灵活空间项不允许作为单独的导航栏按钮项.请使用 rightBarButtonItems(复数)属性.*** 首先抛出调用堆栈:(0 核心基金会 0x00000001132a2e65 __exceptionPreprocess + 1651 libobjc.A.dylib 0x0000000112d19deb objc_exception_throw + 482 CoreFoundation 0x00000001132a2d9d +[NSException raise:format:] + 2053 UIKit 0x000000011156d560 -[UINavigationItem setRightBarButtonItem:animated:] + 1314 sdsd sdsdsd 0x000000010e042dd3 -[SendClipViewController createCustomBtnRightBar:] + 1475

当我是故事板直接的按钮栏并且右侧的空间更小(根据我的需要)时，我之前工作得很好.

任何帮助将不胜感激.谢谢

解决方案

你需要使用 .Fixed Space 来实现:

UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];negativeSpacer.width = -10;self.navigationItem.rightBarButtonItems = @[negativeSpacer, customBarItem];

This is my code

- (void)createCustomBtnRightBar:(UIImage *)buttonImage
{
    self.navigationItem.rightBarButtonItem = nil;
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    if (buttonImage != nil) {
        [button setImage:buttonImage forState:UIControlStateNormal];
        button.frame = CGRectMake(0, 0, 45, 33);
        button.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 0, -10);
    } else {
        [button setTitle:@"Add New Pal" forState:UIControlStateNormal];
        button.frame = CGRectMake(0, 0, 110, 24);
        [button.titleLabel setTextAlignment:NSTextAlignmentRight];
    }

    [button addTarget:self action:@selector(onClickBtnSendClip:) forControlEvents:UIControlEventTouchUpInside];    
    [button setBackgroundColor:[UIColor greenColor]];

    //create a UIBarButtonItem with the button as a custom view
    UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];

    self.navigationItem.rightBarButtonItem = customBarItem;
}

When Change width to 200

When add button.titleEdgeInsets = UIEdgeInsetsMake(0, 20, 0, 0);

In all these cases, the area of the right can not move

I need something like this.

I even tried this

UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
customBarItem.customView = button;

but does crash

Worked perfect before when I was the button bar direct from the story board and space on the right was smaller (as I need).

Any help would be appreciated. Thanks

You need to use .Fixed Space to achieve this:

UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
negativeSpacer.width = -10;
self.navigationItem.rightBarButtonItems = @[negativeSpacer, customBarItem];
