iphone - UIpopoverviewcontroller 单击按钮隐藏 popoverview 并从父 View 打开 imagepicker

Question

大家好，我是新的 iPhone 开发者，

我在打开 uiimagepickercontroller 时遇到问题。

我可以选择在 popoverview 中拍照并打开图库来拍照并打开相机，然后隐藏 popoverview 并打开图库隐藏 popover 并从父 View Controller 打开 imagepicker imagepicker 不应从 popover View Controller 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 Controller

-(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，例如:

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker

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