app name doesn't appear in permission request alert

问题

I am using UIImagePickerController to allow the user to pick images from the device.

When doing it the first time, I get a standard permission request alert, but the app name is missing..

I couldn't find any mention for this in the documentation.

 imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        imagePickerController.mediaTypes = @[(NSString *)kUTTypeImage];
        [self presentViewController:imagePickerController animated:YES completion:nil];

Other permission request (like location services) are displaying the app name appropriately.

回答1:

for some reason, bundle display name in info.plist was blank..

changed it back to $(PRODUCT_NAME) and issue is solved
