关闭 UIImagePickerController

Question

我有以下代码：

SecondViewController *secondView = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];

[imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
[imagePicker setCameraOverlayView:secondView.view];
[imagePicker setShowsCameraControls:NO];

[self presentModalViewController:imagePicker animated:YES];

我的问题是： 如何从“SecondViewController”中关闭 ModalViewController？

Answer 1

您必须从 secondView 中的 UIImagePickerControllerDelegate 方法调用 imagePicker 上的以下内容。

例如：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    // process message
    [imagePicker dismissModalViewControllerAnimated:YES];
}

Answer 2

接受的答案在 iOS7 中不再有效。下面是应该使用的方法。

同样，应该从 UIImagePickerControllerDelegate 在 UIImagePicker 上调用此方法。

-(void) imagePickerController:(UIImagePickerController *)picker
             didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    [[picker presentingViewController] dismissViewControllerAnimated:YES completion:NULL];

}
