Question

当点击它时，是否可以让UIImage导航到另一个ViewController？就像UIButton。

一样

感谢。

Answer 1

你可以使用

var tap = UITapGestureRecognizer(target: self, action: Selector("imageCliecked"))
yourimageView.addGestureRecognizer(tap)
yourimageView.userInteractionEnabled = true // this is must dont forget to add

方法是

func imageCliecked()
{
println("Tapped on Image")
// navigate to another 
self.performSegueWithIdentifier("yoursegueName", sender: self)
}

   override func prepareForSegue(segue: UIStoryboardSegue, sender:AnyObject?)
  {
  if segue.identifier == "yoursegueName" {

  var destViewController: ViewController = segue.destinationViewController as ViewController

  destViewController.img = imageView.image // pass your imageview
   }

   }

另一个ViewController

 class ViewController: UIViewController 
{

 strong var img: UIImage!

 override function viewDidLoad()
 {
  if(self.img)
  self.imageView.image = img;
 }
}

"abcdefg".length - "bcdefg".length
= 7 - 6
= 1

Answer 3

对于你的问题，我尝试了以下解决方案。也正常。

  override func viewDidLoad() 
  {

    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    var tapGesture = UITapGestureRecognizer(target: self, action: "navigationFromImage:")

    tapGesture.numberOfTapsRequired = 1

    imageviewNavigation.userInteractionEnabled = true

    imageviewNavigation.addGestureRecognizer(tapGesture)

  }

 func navigationFromImage(sender: UIGestureRecognizer)
 {

    var secondViewController = storyboard?.instantiateViewControllerWithIdentifier("navigatingSecondViewController") as SecondViewController

    secondViewController.globalImage = imageviewNavigation.image!

    navigationController?.pushViewController(secondViewController, animated: true)
              //OR

    presentViewController(secondViewController, animated: true, completion: nil)

 }

同样在Storyboard中，单击所需的视图控制器

     1.Go to or click show the Identity inspector
     2.Click Identity
     3.In StorybordId you must give "navigatingSecondViewController" or whatever you want.
     4.Finally you must give same name in your storyboard?.instantiateViewControllerWithIdentifier("navigatingSecondViewController")

在SecondViewController中

   var globalImage: UIImage = UIImage()

   override func viewDidLoad() 
   {

      super.viewDidLoad()

      // Do any additional setup after loading the view.

      imageAccess.image = globalImage
   }

是的，可以使用属性......将一个控制器导航到另一个控制器......

e.g。

// second Controller.....(you pass image on this controller)
#import <UIKit/UIKit.h>
@interface NewScreen : UITableViewController
{

}
@property(strong,nonatomic)UIImage *yourImage;
@end


/// First Controller where you pass your image...

- (IBAction)convertVideoButtonClicked:(id)sender
{
    NewScreen *objNew=[self.storyboard instantiateViewControllerWithIdentifier:@"NewScreen"];
    objNew.yourImage=imageNamed;
    [self.navigationController pushViewController:objNew animated:YES];
//  NSURL *videoPath = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"part1" ofType:@"mov"]];
//  [self convertVideoToMP4:videoPath];
}
