UIBarButtonItem 与 UIButton 作为 CustomView 奇怪的问题

Question

我正在使用itiWithCustomView 方法创建UIBarButtonItem 作为rightBarButtonItem，其中customView 是UIButton，contentHorizontalAlignment 作为UIControlContentHorizontalAlignmentRight。
barbuttonitem 工作正常。
但是在一个push popviewcontroller操作之后，barbuttonitem点击区域大大减少了（我认为不超过3-4像素）。
请帮我解决这个问题

UIImage *filterImage = [UIImage imageNamed:@"filter"]; UIButton *filterButton = [UIButton buttonWithType:UIButtonTypeCustom];
filterButton.frame = CGRectMake(0, 0, 44, 44);
filterButton.showsTouchWhenHighlighted = YES; [filterButton setImage:[UIImage imageNamed:@"filter"] forState:UIControlStateNormal];
[filterButton addTarget:self action:@selector(filterTapped:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *filterItem = [[UIBarButtonItem alloc]initWithCustomView:filterButton];
self.navigationItem.rightBarButtonItem = filterItem;

我认为您为将条形按钮移动到右侧一点点分配了对齐方式。取而代之的是，您可以尝试遵循 sn-p。它可能会解决您的问题。

self.navigationItem.rightBarButtonItem = nil;
self.navigationItem.rightBarButtonItems = [self setRightBarButtonWithTarget:self action:@selector(topRightButtonClick) image:@"imagename"];

以及创建创建右栏按钮的常用方法

- (NSArray *)setRightBarButtonWithTarget:(id)target action:(SEL)action image:(NSString *)imgName
{
    UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    rightBtn.backgroundColor = [UIColor clearColor];
    [rightBtn setImage:[UIImage imageNamed:imgName] forState:UIControlStateNormal];
    [rightBtn addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];
    rightBtn.frame = CGRectMake(0, 0, 26, 26);

    UIBarButtonItem *negativeSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
    negativeSpace.width = -5;
    UIBarButtonItem *homeButton = [[UIBarButtonItem alloc] initWithCustomView:rightBtn];

    NSArray *arrBarItems = [NSArray arrayWithObjects:negativeSpace, homeButton, nil];
    return arrBarItems;
}
