iphone - iOS 7 中的 UIImagePickerControllerSourceTypePhotoLibrary 无法正常工作

Question

当我升级到 iOS7 时，当我从应用程序访问照片库时，我的应用程序显示一个空的 View Controller 。它正在与旧的框架一起使用。

 UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
    imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    imagePickerController.delegate = self;
    self.imagePicker = imagePickerController;
    //self.imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentViewController:self.imagePicker animated:YES completion:nil];

Answer 1

请直接申请此代码

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePickerController.delegate = self;
[self presentViewController:imagePickerController animated:YES completion:nil];

当此代码运行时，当您单击“确定”时，将显示“应用程序”想要访问您的照片消息，然后将显示所有图像

谢谢。
