我正在使用PageViewController和标签栏。我有一个问题是“如何通过触摸按钮移动另一个视图”。我的应用程序有5个ViewController，它们位于PageViewController上。并且PageViewController在ViewController上。该ViewController是MainController。所以我用大约4：1（PageViewController：标签栏）分隔了主视图。因此，选项卡栏位于MainController上，当触摸选项卡项目时，MainController可以更改ViewController。
但是我想做的是可以更改ViewController的五个ViewController之一上的按钮。
该按钮无权更改ViewController。因此，我搜索了如何解决此问题，但找不到很好的解决方案。
我认为解决方案很短，大约1〜2句话。
我附上了我的代码，所以希望任何知道如何解决此问题的人都可以帮助我。
我是Swift的新手，请详细说明
这是MainController的一部分
import UIKit
class ViewController: UIViewController, UIPageViewControllerDataSource, UIPageViewControllerDelegate {
var pageViewController: UIPageViewController!
var subVC: [UIViewController] = []
var viewIndex: Int = 0
var tabIndicator1 = UIView()
var tabIndicator2 = UIView()
var tabIndicator3 = UIView()
var tabIndicator4 = UIView()
var tabIndicator5 = UIView()
var views = [UIView]()
override func viewDidLoad() {
super.viewDidLoad()
createVC() // make five ViewControllers
self.pageViewController = self.storyboard?.instantiateViewController(withIdentifier: "PageViewController") as! UIPageViewController
self.pageViewController = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil)
self.pageViewController.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.view.frame.height)
self.addChildViewController(self.pageViewController)
self.view.addSubview(self.pageViewController.view)
let startVC = subVC[0]
viewIndex = 0
let viewControllers = NSArray(object: startVC)
self.pageViewController.setViewControllers(viewControllers as? [UIViewController], direction: .forward, animated: true, completion: nil)
self.pageViewController.didMove(toParentViewController: self)
createTabBar() // make Tab Bar
createIndicator() // make Tab Indicator
self.pageViewController.dataSource = self
self.pageViewController.delegate = self
}
...
func createVC() { // I have five ViewController files
let HomeVC = VCInstance(name: "Home")
let AccessVC = VCInstance(name: "AccessLog")
let RegisterVC = VCInstance(name: "Register")
let SettingVC = VCInstance(name: "Setting")
let HelpVC = VCInstance(name: "Help")
subVC = [HomeVC, AccessVC, RegisterVC, SettingVC, HelpVC]
}
func VCInstance(name: String) -> UIViewController {
return UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: name)
}
....
最佳答案
您可以使用此代码，可能会对您有所帮助。
extension UIViewController {
func goNextPage(animated: Bool = true) {
guard let currentViewController = self.viewControllers?.first else { return }
guard let nextViewController = dataSource?.pageViewController(self, viewControllerAfter: currentViewController) else { return }
setViewControllers([nextViewController], direction: .forward, animated: animated, completion: nil)
}
func goPreviousPage(animated: Bool = true) {
guard let currentViewController = self.viewControllers?.first else { return }
guard let previousViewController = dataSource?.pageViewController(self, viewControllerBefore: currentViewController) else { return }
setViewControllers([previousViewController], direction: .reverse, animated: animated, completion: nil)
}
}
