iOS 7中UINavigationbar下面的UISegmentedControl
Answers:
这是一个简单的效果。
首先，将分段放置在工具栏中。将此工具栏放在导航栏的正下方。设置工具栏视图控制器的代表，并返回UIBarPositionTopAttached在positionForBar:。您可以在商店应用程序中看到，如果执行交互式弹出手势，则该分段栏的移动与导航栏的移动不同。那是因为它们不一样。
现在删除发际线。“发际线”是UIImageView导航栏的子视图。您可以找到它并将其设置为隐藏。例如，这就是Apple在其本机日历应用程序以及商店应用程序中所做的。请记住在当前视图消失时显示它。如果您稍微玩一下Apple应用程序，将会看到发际线设置为隐藏在上，viewWillAppear:并显示为viewDidDisappear:。
要获得搜索栏的样式，只需将其设置为searchBarStyle即可UISearchBarStyleMinimal。
好答案！别忘了更新tableView的contentInset以避免工具栏覆盖内容：-)

“将此工具栏置于导航栏的正下方。” superView应该是什么？

@Koen您的用例更加复杂。创建一个容器视图控制器，然后在其中添加细分。然后将其他控制器添加为段控制器下的子控制器。

仍然感到困惑，最好的方法是添加工具栏，我应该在框架中进行硬编码

initWithRect: CGRectMake(0, self.toplayoutGuide.length, 320, 44)，还是可以使用自动布局来放置它？什么是childView的新顶部self.toplayoutGuide.length + 44？
@Vrutin不要使用条形按钮项。而是，将其添加为工具栏的子视图。然后，您可以将大小设置为工具栏的大小。

现在删除发际线。“细线”是UIImageView，它是导航栏的子视图。您可以找到它并将其设置为隐藏。例如，这就是Apple在其本机日历应用程序以及商店应用程序中所做的。请记住在当前视图消失时显示它。如果您稍微玩一下Apple应用程序，将会看到发际线在viewWillAppear：上设置为隐藏，并在viewDidDisappear：上显示。
另一种方法是查找发际线并将其移至添加的工具栏下方。这是我想出的。
@interface ViewController ()
@property (weak, nonatomic) IBOutlet UIToolbar *segmentbar;
@property (weak, nonatomic) UIImageView *navHairline;
@end
@implementation ViewController
#pragma mark - View Lifecycle
- (void)viewDidLoad
{
[super viewDidLoad];
// find the hairline below the navigationBar
for (UIView *aView in self.navigationController.navigationBar.subviews) {
for (UIView *bView in aView.subviews) {
if ([bView isKindOfClass:[UIImageView class]] &&
bView.bounds.size.width == self.navigationController.navigationBar.frame.size.width &&
bView.bounds.size.height < 2) {
self.navHairline = (UIImageView *)bView;
}
}
}
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self _moveHairline:YES];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[self _moveHairline:NO];
}
- (void)_moveHairline:(BOOL)appearing
{
// move the hairline below the segmentbar
CGRect hairlineFrame = self.navHairline.frame;
if (appearing) {
hairlineFrame.origin.y += self.segmentbar.bounds.size.height;
} else {
hairlineFrame.origin.y -= self.segmentbar.bounds.size.height;
}
self.navHairline.frame = hairlineFrame;
}
@end
我还发现Apple NavBar代码示例（自定义UINavigationBar）对于解决此问题非常有用。
另外，请务必处理UIToolbar的顶部边框，它可能会出现，并且您可能会将其与NavBar的细线混淆。我还希望UIToolbar看起来与NavBar完全一样，然后您可能想要调整ToolbarsbarTintColor。
这是一个基于协议的Swift快速解决方案，以公认的答案为基础：
HideableHairlineViewController.swift
protocol HideableHairlineViewController {
func hideHairline()
func showHairline()
}
extension HideableHairlineViewController where Self: UIViewController {
func hideHairline() {
findHairline()?.hidden = true
}
func showHairline() {
findHairline()?.hidden = false
}
private func findHairline() -> UIImageView? {
return navigationController?.navigationBar.subviews
.flatMap { $0.subviews }
.flatMap { $0 as? UIImageView }
.filter { $0.bounds.size.width == self.navigationController?.navigationBar.bounds.size.width }
.filter { $0.bounds.size.height <= 2 }
.first
}
}
SampleViewController.swift
import UIKit
class SampleViewController: UIViewController, HideableHairlineViewController {
@IBOutlet private weak var toolbar: UIToolbar!
@IBOutlet private weak var segmentedControl: UISegmentedControl!
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
hideHairline()
}
override func viewDidDisappear(animated: Bool) {
super.viewDidDisappear(animated)
showHairline()
}
}
// MARK: UIToolbarDelegate
extension SampleViewController: UIToolbarDelegate {
func positionForBar(bar: UIBarPositioning) -> UIBarPosition {
return .TopAttached
}
}

shadowImage导航栏的属性。
嗨，您能解释一下如何在Interface Builder中放置工具栏吗？自动布局？您还能注释掉上面的扩展名，看看会发生什么吗？我认为这无效。

您可以在Apple示例代码中找到带有UISegmentedControl的导航栏：https : //developer.apple.com/library/ios/samplecode/NavBar/Introduction/Intro.html
或者，您也可以通过编程方式创建它，这是我在其他线程中的答案中的代码 将分段控件添加到导航栏并使用按钮保留标题
我想做同样的事情。

if (self) {
[self initialize];
}
return self;
}
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
[self initialize];
}
return self;
}
- (void)initialize {
// Set tittle position for top
[self setTitleVerticalPositionAdjustment:-(MyNavigationBarHeightIncrease) forBarMetrics:UIBarMetricsDefault];
}
- (CGSize)sizeThatFits:(CGSize)size {
// Increase NavBar size
CGSize amendedSize = [super sizeThatFits:size];
amendedSize.height += MyNavigationBarHeightIncrease;
return amendedSize;
}
- (void)layoutSubviews {
// Set buttons position for top
[super layoutSubviews];
NSArray *classNamesToReposition = @[@"UINavigationButton"];
for (UIView *view in [self subviews]) {
if ([classNamesToReposition containsObject:NSStringFromClass([view class])]) {
CGRect frame = [view frame];
frame.origin.y -= MyNavigationBarHeightIncrease;
[view setFrame:frame];
}
}
}
- (void)didAddSubview:(UIView *)subview
{
// Set segmented position
[super didAddSubview:subview];
if ([subview isKindOfClass:[UISegmentedControl class]])
{
CGRect frame = subview.frame;
frame.origin.y += MyNavigationBarHeightIncrease;

UINavigationButton是私有API，您的应用将被拒绝使用。您应该尝试掩盖该类的使用。
@LeoNatan在搜寻之后决定冒险将我的应用程序保存在我的答案和zhas中！获准

iTSangar 2014年
请记住，即使您一次获得批准，也有可能在将来的某个日期被拒绝，否则Apple可能在以后的提交中拒绝您。至少需要做少量工作来隐藏私有API的使用。

您的解决方案很棒，我可以在导航栏中添加任何内容，但不幸的是，我无法单击添加到视图中的任何对象： ）

iDev 2015年
看起来不错，除了“后退”按钮（恰好被添加到底部）之外。

gklka 2015年
苹果有专门用于此的示例应用程序。它介绍了为导航栏设置透明阴影图像和彩色背景图像，以及如何在导航栏下方配置视图。它还具有其他导航栏自定义示例。
参见https://developer.apple.com/library/ios/samplecode/NavBar/Introduction/Intro.html
我尝试使用@Simon的方法删除发际线，但没有成功。我可能做错了，因为我是超级菜鸟。但是，除了删除该行之外，您还可以使用hidden属性将其隐藏。这是代码：
var hairLine: UIView = UIView()
override func viewDidLoad() {
super.viewDidLoad()
doneButton.enabled = false
for parent in self.navigationController!.navigationBar.subviews {
for childView in parent.subviews {
if childView is UIImageView && childView.bounds.size.width == self.navigationController!.navigationBar.frame.size.width {
hairLine = childView
}
}
}
}
override func viewWillAppear(animated: Bool) {
hairLine.hidden = true
}
override func viewWillDisappear(animated: Bool) {
hairLine.hidden = false
}希望这对某人有帮助！
