iOS OC 导航栏自定义rightBarButtonItem

UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
    customView.backgroundColor = [UIColor lightGrayColor];

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 34, 80, 10)];
    label.text = @"Custom";
    label.textAlignment = NSTextAlignmentCenter;
    [customView addSubview:label];
    
    UIImage *image = [UIImage imageNamed:@"collect"];
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setFrame:CGRectMake(33, 0, 34, 34)];
    [button setImage:image forState:UIControlStateNormal];
    [button addTarget:self action:@selector(collectBtnClicked) forControlEvents:UIControlEventTouchUpInside];
    [customView addSubview:button];

    UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:customView];
    self.navigationItem.rightBarButtonItem = barButtonItem;//rightBarButtonItems是一样的（多个的时候用s）

下面我自己用的

 UIView *containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
    containerView.backgroundColor = [UIColor clearColor];
    [containerView addSubview:self.customerServiceButton];
    // 将自定义按钮添加到UIBarButtonItem中
    UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc] initWithCustomView:containerView];
    // 将按钮添加到导航项的右侧
    self.navigationItem.rightBarButtonItems = @[rightBarButton];

@property (nonatomic, strong) QMUIButton *customerServiceButton;//客服按钮

#pragma mark - Setter && Getter 懒加载
//客服按钮
-(QMUIButton *)customerServiceButton{
    if (!_customerServiceButton) {
        _customerServiceButton = [QMUIButton buttonWithType:UIButtonTypeCustom];
        [_customerServiceButton setFrame:CGRectMake(76, 10, 24, 24)];
        [_customerServiceButton setImage:UIImageMake(@"下载 2") forState:UIControlStateNormal];
        [_customerServiceButton addTarget:self action:@selector(customerServiceButtonEvent) forControlEvents:UIControlEventTouchUpInside];
    }
    return _customerServiceButton;
}

- (void)customerServiceButtonEvent{
    NSLog(@"用户点击了客服按钮888");
    ZXJKeFuViewController *vc= [[ZXJKeFuViewController alloc] init];
    [self.navigationController pushViewController:vc animated:YES];
}

有人这样写

- (void)createRightItem{
    
 
    
    self.navigationItem.rightBarButtonItem = [UIBarButtonItem qmui_itemWithImage:UIImageMake(@"下载 2") target:self action:@selector(rightClick)];
    
    self.navigationItem.rightBarButtonItem.tintColor = UIColorMakeWithHex(@"#292929");
}

- (void)rightClick{
    
    [self addNewAdsClick];

    
}

- (void)addNewAdsClick
{
    ZXJKeFuViewController* vc= [[ZXJKeFuViewController alloc] init];
    [self.navigationController pushViewController:vc animated:YES];
    
}
