Ipad UIImagePickerController和UIPopoverController错误 [英] Ipad UIImagePickerController and UIPopoverController error

问题描述

我使用此代码打开带有imagepicker的popover

I am using this code to open a popover with imagepicker

-(IBAction)photosAction:(id)sender 
{
// dismiss any left over popovers here
UIImagePickerController* picker = [[UIImagePickerController alloc] init]; 
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
picker.delegate = self; 

UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
self.popoverController = popover;          
popoverController.delegate = self;
[popoverController presentPopoverFromBarButtonItem:sender  permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
[picker release];

但这会导致错误成员'popoverController'的请求，而不是结构或联盟并且此错误'popoverController'未声明（首次在此函数中使用）。

But this results in this error request for member 'popoverController' in something not a structure or union and this error 'popoverController' undeclared (first use in this function).

此外我想解雇popover时选择了图像。

Also I want to dismiss the popover when the image is selected.

选择图像后，我应该在以下函数中添加什么代码来解除弹出窗口。

What code should I put in the following function to dismiss the popover once the image is selected.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

感谢您的帮助！

推荐答案

此错误是由于我的功能需要栏按钮项目，我使用的是普通的ui按钮。

This error was caused becaused my function requires a bar button item and i was using a normal ui button.
