iphone - 如何关闭imagePickerController？

Question

我就是听不懂:

到底如何才能在 xcode 上“关闭”imagePickerController？这是打开相机的代码，它工作得很好..

-(IBAction) startcamera {


imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.allowsEditing = NO;
imagePickerController.showsCameraControls=NO;
imagePickerController.toolbarHidden=YES ;
imagePickerController.wantsFullScreenLayout=YES;
imagePickerController.cameraOverlayView=self.view;
self.imagePickerController.delegate=self;
    [self presentModalViewController:imagePickerController animated:YES];
[imagePickerController release];

}

现在，假设我想通过单击按钮来关闭 imagePickerController(意味着不选择任何图像):我该怎么做？尝试过:

-(IBAction)closecamera {


[imagePickerController release];
    [imagePickerController dismissModalViewControllerAnimated:YES];

}

但它不起作用!有什么线索吗？提前致谢

Answer 1

1. 不要释放 imagePickerController 两次。
2. 您可以使用 [selfmissModalViewControllerAnimated:YES];
关闭它
