如何在UINavigationBar中添加UISegmentedControl？ [英] How to add the UISegmentedControl in UINavigationBar?

问题描述

我尝试将 UISegmentedControl 添加到带有标题的 UINavigationBar 的底部。但我无法添加它，我无法在 tableView.headerView 中添加 UISegmentedControl ，因为我需要在 tableView.headerView ，所以只需要一个解决方案，我需要将 UISegmentedControl 添加到<$ c $的底部C> UINavigationBar的。任何人都有另外的想法，我可以解决这种情况吗？

I have tried to add the UISegmentedControl to the bottom of UINavigationBar with title. But i cannot add it and I cannot add UISegmentedControl in the tableView.headerView,because i need the search bar in the tableView.headerView, so there is just one solution that i need to add UISegmentedControl to the bottom of UINavigationBar. Anyone have another idea that i can solve this situation?

这是我尝试过的代码（使用 Swift ）：

Here is the code that I have tried(with Swift):

        class searchingViewController: UITableViewController{ 
                override func viewDidLoad() {         
                    var items: [AnyObject] = ["Searching Method A", "Searching Method B"]
                    var searchSC:UISegmentedControl!
                    searchSC.frame = CGRectMake(0, 0, frame.width - 20, 30)
                    searchSC.selectedSegmentIndex = 1
                    searchSC.backgroundColor = UIColor(white: 1, alpha: 1)
                    searchSC.layer.cornerRadius = 5.0
                    navigateUIToolBar = UIToolbar(frame: CGRectMake(frame.minX + 10, ios7_8Info.getStatusBarHeight()+self.navigationController!.navigationBar.frame.height+frame.minY+(21/2),
                        frame.width - 20, 30))

                    navigateUIToolBar.addSubview(searchSC)
                    self.navigationController?.navigationBar.addSubview(navigateUIToolBar)
                  }
          }

推荐答案

把它放入navigationBar有这样的东西左右和标题视图...使用....访问。

To put it in the navigationBar has a right left and title view for such things... accessed using....

self.navigationItem.titleView = mySegmentedControl

供将来参考....

self.navigationItem.rightBarButtonItem
self.navigationItem.leftBarButtonItems // for adding an Array of items

要将其添加到导航视图下方但将其设置为静态..添加它到viewController.view ...你在使用UITableViewController吗？如果是这样，可以切换到UIViewController并添加一个tableView，然后将您的toolbarview作为该self.view的子视图。

To add it below the navigation view but have it static.. add it to the viewController.view... Are you using a UITableViewController? If so maybe switch to a UIViewController and add a tableView then your toolbarview as subviews to that self.view.
