ios - 为什么不能从 UIActivityViewController 中删除 Gmail？

Question

我想从我的 UIActivityViewController 中删除 Gmail。这是我的以下代码：

ActivityViewController *activityVC = [[ActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
activityVC.completionWithItemsHandler = ^(NSString *activityType, BOOL completed, NSArray *returnedItems, NSError *activityError) {
    NSLog(@"%@", activityType);
};

NSArray *excludeActivities = @[@"com.google.Gmail.ShareExtension"];

activityVC.excludedActivityTypes = excludeActivities;

[self presentViewController:activityVC animated:YES completion:nil];

但 Gmail 仍然存在！有人建议如何删除吗？

笔记

我com.google.Gmail.ShareExtension从打印的日志中得到
