如何直接进入“所有照片”相册？

Question

My code is like this:

oldPicker = [[UIImagePickerController alloc] init];
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
{
   oldPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
   oldPicker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:oldPicker.sourceType];
}
oldPicker.delegate = self;
oldPicker.allowsEditing = NO;
[self presentViewController:oldPicker animated:YES completion:nil];

The effects is when I click the button,it shows me the albums choosing view,but I just want to skipping the albums choosing view and directly show the "All Photos" albums.

I have tried to setting the sourceType to UIImagePickerControllerSourceTypeSavedPhotosAlbum , but it shows me the "Moments" albums but not the "All Photos" albums

Answer 1

There is no way to do that using UIImagePickerController .

There are only 3 values available for UIImagePickerControllerSourceType .

 enum { UIImagePickerControllerSourceTypePhotoLibrary, UIImagePickerControllerSourceTypeCamera, UIImagePickerControllerSourceTypeSavedPhotosAlbum }; typedef NSUInteger UIImagePickerControllerSourceType; 

Constants

 UIImagePickerControllerSourceTypePhotoLibrary 

Specifies the device's photo library as the source for the image picker controller.

 UIImagePickerControllerSourceTypeCamera 

Specifies the device's built-in camera as the source for the image picker controller. Indicate the specific camera you want (front or rear, as available) by using the cameraDevice property.

 UIImagePickerControllerSourceTypeSavedPhotosAlbum 

Specifies the device's Camera Roll album as the source for the image picker controller. If the device does not have a camera, specifies the Saved Photos album as the source.

So for achieving the scenario you mentioned you need to write your own image picker. There is a custom control available, you can check that also CTAssetsPickerController
