UIpopoverviewcontroller单击该按钮隐藏popoverview并从父视图打开imagepicker

Question

大家好我是新的iphone开发者，

打开uiimagepickercontroller时遇到问题。

我可以选择拍照并在popoverview中打开图库来拍照并打开相机，时间隐藏popoverview并打开图库隐藏弹出框并从父视图控制器打开图像拾取器imagepicker不应该从弹出视图控制器打开。

请分享您的想法。

Answer 1

//用于打开相机

-(void)btnCameraClicked {
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
        imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        [self presentModalViewController:imgPicker animated:YES];
    }
    else {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Camera is not Available" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok",nil];
        [alert show];
        [alert release];
    }
}

//用于打开图像选择器控制器

-(void)btnGalleryClicked {
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
        imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentModalViewController:imgPicker animated:YES];
    }
    else {
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:@"Photos are not available" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok",nil];
        [alert show];
        [alert release];
    }
}

在此之后，您可以使用ImagePicking方法，如：

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker

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

Answer 2

您可以使用UIPopoverControllerDelegate方法

-(void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController;
