iOS的11导航栏图标问题

问题描述：

iOS的11导航问题，我需要设置导航栏

这是我当前的代码左右和标题视图。

原来是这样，但现在我有问题吧：

btnMenu = [UIButton buttonWithType:UIButtonTypeSystem]; 
    [btnMenu setFrame:CGRectMake(0, 0, 25, 25)]; 
    [btnMenu setTintColor:[UIColor blackColor]]; 
    [btnMenu setContentHorizontalAlignment:UIControlContentHorizontalAlignmentLeft]; 
    [btnMenu setImage:[UIImage imageNamed:@"menu"] forState:UIControlStateNormal]; 
    [btnMenu addTarget:self action:@selector(clickOnMenu:) forControlEvents:UIControlEventTouchUpInside]; 

    leftBarButton2 = [[UIBarButtonItem alloc] initWithCustomView:btnMenu]; 

    [arrLeftBarButton addObject:leftBarButton2]; 

self.navigationItem.leftBarButtonItems = [NSArray arrayWithArray:arrLeftBarButton]; 


[viewTitle addSubview:search]; 
[viewTitle addSubview:btnSelectSearch]; 
viewTitle.translatesAutoresizingMaskIntoConstraints = false; 

self.navigationItem.titleView = viewTitle; 

BBBadgeBarButtonItem *badgeNotify = [[BBBadgeBarButtonItem alloc] initWithCustomUIButton:btnNotify]; 
badgeNotify.badgeBGColor = [UIColor whiteColor]; 
badgeNotify.badgeTextColor = [UIColor blackColor]; 
badgeNotify.badgeValue = @"0"; 

self.navigationItem.rightBarButtonItem = badgeNotify;

看到https：//开头计算器.com/questions/44442573/navigation-bar-rightbaritem-image-button-bug-ios-11 –

It似乎您正在设置导航栏不是建议大小的图像。查看人机界面指南：https：//developer.apple.com/ios/human-interface-guidelines/icons-and-images/custom-icons/ PS：如果您可以发布您的代码，我们会更容易。所以可以指出实际问题。 – Rishi

对象 -

NSLayoutConstraint * widthConstraint = [btnMenu.widthAnchor constraintEqualToConstant:25]; 
NSLayoutConstraint * heightConstraint =[btnMenu.heightAnchor constraintEqualToConstant:25]; 
[widthConstraint setActive:YES]; 
[heightConstraint setActive:YES]; 

UIBarButtonItem* btnMenuItem = [[UIBarButtonItem alloc] initWithCustomView: btnMenu]; 
self.navigationItem.leftBarButtonItem = btnMenuItem;

斯威夫特

let widthConstraint = button.widthAnchor.constraint(equalToConstant: 25) 
let heightConstraint = button.heightAnchor.constraint(equalToConstant: 25) 
heightConstraint.isActive = true 
widthConstraint.isActive = true
