Currently, we probably cannot disable Save to Files or Add to Shared Album by add excludedActivityTypes in activityViewController. But we can prevent when user did press two activity types will do not perform action instead we'll showing alert.
First we create custom UIActivityItemProvider
class ActivityItemProvider: UIActivityItemProvider {
override func activityViewController(_ activityViewController: UIActivityViewController, itemForActivityType activityType: UIActivityType) -> Any? {
// in here we'll check activityType = "com.apple.CloudDocsUI.AddToiCloudDrive" (Save to Files),
// activityType = "com.apple.mobileslideshow.StreamShareService" (Shared Album)
if(activityType.rawValue.contains("com.apple.CloudDocsUI.AddToiCloudDrive") || (activityType.rawValue.contains("com.apple.mobileslideshow.StreamShareService") {
// dismiss activityViewController first
activityViewController.dismiss(animated: true, completion: nil)
// show alert controller, we can using UIApplication.shared.keyWindow?.rootViewController to present alert
return nil
}
return self.placeholderItem
}
In where we call UIActivityController, let's using
let item = ActivityItemProvider.init(placeholderItem: {your item})
let activityViewController = UIActivityViewController.init(activityItems: item, applicationActivities: nil)
ObjectiveC version
#import "BRActivityItemProvider.h"
#import "UIViewController+Additions.h"
@implementation BRActivityItemProvider
- (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(UIActivityType)activityType {
[super activityViewController:activityViewController itemForActivityType:activityType];
NSLog(@"itemForActivityType %@", activityType);
if([activityType containsString:@"com.apple.CloudDocsUI.AddToiCloudDrive"] || [activityType containsString:@"com.apple.mobileslideshow.StreamShareService"]) {
[activityViewController dismissViewControllerAnimated:true completion:^{
UIViewController *rootController = [UIApplication sharedApplication].keyWindow.rootViewController;
if(rootController != nil) {
NSString *str = [activityType containsString:@"com.apple.CloudDocsUI.AddToiCloudDrive"]
? @"Cannot save file to iCloud Driver"
: @"Cannot save file to Shared Album";
dispatch_async(dispatch_get_main_queue(), ^{
// this's my custom show alert controller, you can change your own
[rootController showAlertController:str action:^(UIAlertAction * _Nonnull action) {
}];
});
}
}];
return nil;
}
return self.placeholderItem;
}
In where call UIActivityViewController
BRActivityItemProvider *itemProvider = [[BRActivityItemProvider alloc]initWithPlaceholderItem:item];
UIActivityViewController *activityController = [[UIActivityViewController alloc]initWithActivityItems:itemProvider applicationActivities:nil];
activityController.popoverPresentationController.sourceView = controller.view;
// your logic code
// ....
