Iphone UIPopOverview控制器单击按钮隐藏popoverview并从父视图打开imagepicker

大家好，我是新的iphone开发者

打开uiimagepickercontroller时出现问题

我可以选择拍摄照片并在popoverview中打开gallery以拍摄照片并打开相机隐藏popoverview并打开gallery从父视图控制器隐藏popover并打开imagepicker imagepicker不应从popover视图控制器打开

请分享你的想法

//用于打开摄像头

-(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，您可以使用图像拾取方法，如：

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker

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

//用于打开摄像机

-(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，您可以使用图像拾取方法，如：

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker

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

您可以使用UIPopoverControllerDelegate方法

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