IOS 10 UIImagePickerController委托未被调用

Question

我已设置以下内容以在使用iPad时选择图像。问题是委托似乎永远不会被调用。我已经设置了断点，但它们从未被激活过。

·H

@interface HomeViewController : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate>

.M

- (IBAction)loadImage:(id)sender {

self.imagePickerController = [[UIImagePickerController alloc] init];
self.imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
self.imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
self.imagePickerController.allowsEditing = NO;
self.imagePickerController.delegate = self;

[self presentViewController:self.imagePickerController animated:YES completion:nil];

}

// This method is called when an image has been chosen from the library or taken from the camera.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

//You can retrieve the actual UIImage
UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
//Or you can get the image url from AssetsLibrary
NSURL *path = [info valueForKey:UIImagePickerControllerReferenceURL];

[picker dismissViewControllerAnimated:YES completion:nil];
}

有人能看到这个问题吗？

如果您使用Xcode8来运行项目，请检查项目的info.plist，确保有一个用于＆＃34;隐私照片库使用的密钥＆＃34;。

你的代码是对的，也许问题是info.plist。

Answer 2

我遇到了类似的问题，事实证明，一旦选择了图像，拾取器就会被垃圾收集，因此代理人没有被调用。

我需要确保在呈现之前对选择器进行了强有力的引用。

一旦完成，它工作正常。
