如何从UIActivityViewController中排除Notes和提醒应用程序？ [英] How to exclude Notes and Reminders apps from the UIActivityViewController?

问题描述

我创建了一个 UIActivityViewController 并传递 String 和 URL 到它。这显然配置 UIActivityViewController 使用一些我想排除的项目（我的目标是分享我的应用程序的信息）。

通过设置相应的 excludedActivityTypes ，我已经排除了大量系统提供的活动（如添加到阅读列表）。

但是，我无法排除提醒和Notes应用程序。有人可以建议一种做法吗？这些应用程序在列表中显示为第3和第4，因此除非用户滚动，否则Twitter和Facebook不可见。

解决方案

，但涉及私人API 。

有时苹果会出现异常，特别是如果您修复了错误。

让我们深入细节...

UIActivityViewController 方法称为_availableActivitiesForItems：，它返回一个 UISocialActivity 对象的数组。

UISocialActivity ，称为activityType，它返回一个域格式的活动类型。

经过一些测试，我设法发现了提醒和Notes活动类型：

• com.apple.reminders.RemindersEditor扩展


• com.apple.mobilenotes.SharingExtension

很遗憾，将这两种类型传递到.excludedActivityTypes没有任何区别。

_ availableActivitiesForItems：救援！

老方式：

更新：I发现了一个更好的方法。

我发布的第一个解决方案在某些情况下不工作，因此不应该被认为是稳定的。 p>

标题：

  #import< UIKit / UIKit.h> 
 
 @interface UISocialActivity：NSObject 
 
  - （id）activityType; 
 
 @end 
 
 @interface UIActivityViewController（Private）
 
  - （id）_availableActivitiesForItems：（id）arg1; 
 
 @end 
 
 @interface ActivityViewController：UIActivityViewController 
 
 @end 
  

实现：

  @implementation ActivityViewController 
 
  - （id）_availableActivitiesForItems：（id）arg1 
 {
 id activities = [super _availableActivitiesForItems：arg1]; 
 NSMutableArray * filteredActivities = [NSMutableArray array]; 
 
 [活动enumerateObjectsUsingBlock：^（UISocialActivity * _Nonnull obj，NSUInteger idx，BOOL * _Nonnull stop）{
 
 if（！[[obj activityType] isEqualToString：@com。 apple.reminders.RemindersEditorExtension]&& 
！[[obj activityType] isEqualToString：@com.apple.mobilenotes.SharingExtension]）{
 [filteredActivities addObject：obj]; 
} 
 
}]; 
 
 return [NSArray arrayWithArray：filteredActivities]; 
} 
 @end 
  

$ b

新办法：

标题：

  @interface UIActivityViewController（Private）
 
  - （BOOL）_shouldExcludeActivityType：（UIActivity *）activity; 
 
 @end 
 
 @interface ActivityViewController：UIActivityViewController 
 
 @end 
  

实现：

  @implementation ActivityViewController 
 
  - （BOOL）_shouldExcludeActivityType：（UIActivity *）activity 
 {
 if（[[activity activityType] isEqualToString：@com.apple.reminders.RemindersEditorExtension] || 
 [[activity activityType] isEqualToString：@com.apple.mobilenotes.SharingExtension]）{
 return YES; 
} 
 return [super _shouldExcludeActivityType：activity]; 
} 
  

@end

Illegal，但它的工作原理。

很高兴知道它是否真的通过苹果验证。

I am creating a UIActivityViewController and pass String and URL to it. This, obviously, configures the UIActivityViewController to use some items which I want to exclude (my objective is to share the info about my app).

I have managed to exclude lots of system provided activities (like 'Add to Reading list') by setting the appropriate excludedActivityTypes.

However, I am unable to exclude Reminders and Notes apps. Can someone suggest a way of doing it? These apps appear 3rd and 4th on the list and therefore make Twitter and Facebook not visible unless user scrolls.

解决方案

There is a way, but involves private API.

Sometimes Apple makes exceptions, especially if you fix a bug.

Let's dive into details...

UIActivityViewController has got a private method called "_availableActivitiesForItems:", which returns an array of UISocialActivity objects.

UISocialActivity has got an interesting property, called "activityType", which returns a domain-formatted activity type.

After some tests, I managed to discover the Reminder and Notes activity types:

• com.apple.reminders.RemindersEditorExtension
• com.apple.mobilenotes.SharingExtension

Unfortunately, passing those two types into ".excludedActivityTypes" didn't make any difference.

"_availableActivitiesForItems:" to the rescue!

OLD WAY:

Update: I've found a better way to do it.

The first solution I've posted doesn't work in some cases, thus shouldn't be considered stable.

Header:

#import <UIKit/UIKit.h>

@interface UISocialActivity : NSObject

- (id)activityType;

@end

@interface UIActivityViewController (Private)

- (id)_availableActivitiesForItems:(id)arg1;

@end

@interface ActivityViewController : UIActivityViewController

@end

Implementation:

@implementation ActivityViewController

- (id)_availableActivitiesForItems:(id)arg1
{
    id activities = [super _availableActivitiesForItems:arg1];
    NSMutableArray *filteredActivities = [NSMutableArray array];

    [activities enumerateObjectsUsingBlock:^(UISocialActivity*  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {

        if (![[obj activityType] isEqualToString:@"com.apple.reminders.RemindersEditorExtension"] &&
            ![[obj activityType] isEqualToString:@"com.apple.mobilenotes.SharingExtension"]) {
            [filteredActivities addObject:obj];
        }

    }];

    return [NSArray arrayWithArray:filteredActivities];
    }
    @end

NEW WAY:

Header:

@interface UIActivityViewController (Private)

- (BOOL)_shouldExcludeActivityType:(UIActivity*)activity;

@end

@interface ActivityViewController : UIActivityViewController

@end

Implementation:

@implementation ActivityViewController

- (BOOL)_shouldExcludeActivityType:(UIActivity *)activity
{
    if ([[activity activityType] isEqualToString:@"com.apple.reminders.RemindersEditorExtension"] ||
        [[activity activityType] isEqualToString:@"com.apple.mobilenotes.SharingExtension"]) {
        return YES;
    }
    return [super _shouldExcludeActivityType:activity];
}

@end

"Illegal", but it works.

It would be great to know if it actually passes Apple validation.
