将图像传递给下一个视图
提问于 2015-05-19 07:45:46
我设法让用户在单击按钮时从他的图库中选择一个图像，但是当用户选择一个图像时，我如何移动到下一个视图？
下面是我从图库中选择图像的代码
@IBAction func gallery(sender: AnyObject) {
var image = UIImagePickerController()
//image.delegate = self
image.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
image.allowsEditing = false
self.presentViewController(image, animated: true, completion: nil)
}当我删除注释时，一个错误显示为
cannot assign a value of type 'postChoices' to a value of type 'protocol<UIImagePickerControllerDelegate>?我在这里尝试做的是，当从图库中选择一张图片时，转到下一个视图，并在另一个视图中查看它

//Add Delegate to ur View Controller UIImagePickerControllerDelegate
class ViewController: UIViewController, UIImagePickerControllerDelegate
//Create Variable
var controller: UIImagePickerController?
//Delegate Methods
func imagePickerControllerDidCancel(picker: UIImagePickerController!) {
println("Picker was cancelled")
picker.dismissViewControllerAnimated(true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController!,
didFinishPickingMediaWithInfo info: [NSObject : AnyObject]!){
println("Picker returned successfully")
}//和View did load方法
controller = UIImagePickerController()
if let theController = controller{
theController.delegate = self
theController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
theController.allowsEditing = false
