ios - 从 Swift 中的画廊中挑选图像

Question

我在 View Controller 中有一个 ImageView 。我想在用户从图库中选择图像时设置此图像。

我试过这段代码:

@IBOutlet var profilePicture: UIImageView!
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {
    self.dismissViewControllerAnimated(true, completion:nil)
    println("image selected from gallery")
    self.profilePicture.image = image
}

它向控制台打印调试消息，但没有更改图像。我该如何解决这个问题？

您只是忘记将从画廊获得的图像分配给您的 UIImageView。

@IBOutlet var profilePicture: UIImageView!
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {
    profilePicture.image = image

    self.dismissViewControllerAnimated(true, completion: { () -> Void in   
    })
    println("image selected from gallery")
    self.profilePicture.image=image
}
