Ios 以编程方式从一个ViewController转到另一个ViewController

我以编程的方式设置了这个按钮，我一直在试图弄清楚，当按下它时，如何切换到另一个

ViewController

。我一直在尝试查找实现这一点所需的代码类型。我好像找不到

import UIKit

class ViewController: UITableViewController {

    override func viewDidLoad() {
    super.viewDidLoad()

    let image = UIImage(named: "Camera.png") as UIImage!
    let button = UIButton.buttonWithType(UIButtonType.System) as! UIButton
    button.frame = CGRectMake(self.view.frame.width / 2 - 30, self.view.frame.size.height - 70, 70, 70)
    button.setImage(image, forState: .Normal)
    self.navigationController?.view.addSubview(button)
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


}

这就是我如何进行设置的。请有人告诉我需要使用哪种类型的代码，或者给我举个例子。谢谢

只要一句话

self.navigationController!.pushViewController(self.storyboard?.instantiateViewC‌​ontrollerWithIdentifier("view2") as! UIViewController, animated: true)

---

首先，通过以下方式向按钮添加操作：

button.addTarget(self, action: "buttonTapAction:", forControlEvents: UIControlEvents.TouchUpInside)

然后添加辅助对象方法：

func buttonTapAction(sender:UIButton!){

    //this code will navigate to next view when you press button.
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewControllerWithIdentifier("SecondViewController") as! SecondViewController
    self.navigationController?.pushViewController(vc, animated: true)
}

完整代码：

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let image = UIImage(named: "s.png") as UIImage!
        let button = UIButton.buttonWithType(UIButtonType.System) as! UIButton
        button.frame = CGRectMake(self.view.frame.width / 2 - 30, self.view.frame.size.height - 70, 70, 70)
        button.setImage(image, forState: .Normal)
        button.addTarget(self, action: "buttonTapAction:", forControlEvents: UIControlEvents.TouchUpInside)
        self.view.addSubview(button)
    }

    func buttonTapAction(sender:UIButton!){

        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let vc = storyboard.instantiateViewControllerWithIdentifier("SecondViewController") as! SecondViewController
        self.navigationController?.pushViewController(vc, animated: true)
    }
}

创建从ViewController到TargetViewController的手动序列

现在，向按钮添加一个操作

button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)

在行动中做到这一点

func buttonAction(sender:AnyObject)
{
    self.performSegueWithIdentifier("manualSegue", sender: nil)
}

希望这对您有所帮助。

首先为按钮创建一个操作，如下所示

- (IBAction)btnInvite:(id)sender {

}

然后导入要继续的viewcontroller，如

#import "YourViewController.h"

最后，把下面的代码放到按钮操作方法中，不管我们在上面创建了什么

- (IBAction)btnInvite:(id)sender {
YourViewController *viewController=[self.storyboard instantiateViewControllerWithIdentifier:@"YourViewController Identifier Name"];
[self.navigationController pushViewController:viewController animated:YES];}

希望对你有用

let VC = self.storyboard?.instantiateViewController(withIdentifier:"yourViewController") as! yourViewController
 self.navigationController?.pushViewController(VC, animated:true)

仅使用您的Viewcontroller名称更改您的Viewcontroller

您需要如何从一个VC跳转到另一个VC的代码示例吗？您好，谢谢您的帮助，这很有效，但我对self.navigationController有问题吗？因为我设置按钮的方式是将其覆盖在选项卡视图上。请尝试以下操作：

self.presentViewController（vc，动画：true，完成：nil）

请为您的答案添加一些解释，以便将来的用户更好地理解您的代码。
