Question

如何在纵向设备方向内将 View 转换为横向

我的 View Controller 代码。

import UIKit

class SampleViewController: UIViewController {


    var commingtextview:String = ""


    @IBOutlet weak var textview: UITextView!


    override func viewDidLoad() {
        super.viewDidLoad()

        navigationController!.navigationBar.barTintColor = UIColorFromRGBs(0x000000)
        navigationController!.navigationBar.tintColor = UIColor.whiteColor();


       textview.text = self.commingtextview

    }

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


}

使用:-

override func viewWillAppear(animated: Bool) {

    super.viewWillAppear(animated)


    self.view.transform = CGAffineTransformMakeRotation(CGFloat(M_PI_2))
  // Set whatever frame you want
  // self.view.frame = CGRectMake(xOrigin,yOrigin,Width,Height)


}
