Ios UIActivityViewController中各个活动的不同活动项

是否可以为

UIActivityViewController

中的每个活动使用不同的活动项？例如，我有以下代码：

NSArray *objectsToShare = @[schemeURL, wordedString];
controller = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

// Exclude all activities except AirDrop.
NSArray *excludedActivities = @[UIActivityTypePostToTwitter,
                                    UIActivityTypePostToWeibo,
                                    UIActivityTypeAssignToContact, UIActivityTypeSaveToCameraRoll,
                                    UIActivityTypeAddToReadingList, UIActivityTypePostToFlickr,
                                    UIActivityTypePostToVimeo, UIActivityTypePostToTencentWeibo];
controller.excludedActivityTypes = excludedActivities;
[self presentViewController:controller animated:YES completion:nil];

我想将要发送到Facebook的数据设置为

wordedString

属性，并将要通过空投发送的数据设置为

schemeURL

属性。这可能吗？提前感谢。

您可以将UIActivityItemProvider子类化，并可以使用以下方法检查活动类型。。试试看

//- Returns the data object to be acted upon. (required)
- (id)activityViewController:(UIActivityViewController *)activityViewController itemForActivityType:(NSString *)activityType
{
if ([activityType isEqualToString:UIActivityTypePostToFacebook]) {
    NSString *theText = @"Some text for Facebook";
    return theText;
}

if ([activityType isEqualToString:UIActivityTypePostToTwitter]) {
    NSString *theText = @"Some text for Twitter";
    return theText;
}

if ([activityType isEqualToString:UIActivityTypePostToWeibo]) {
    NSString *theText = @"Some text for Weibo";
    return theText;
}

if ([activityType isEqualToString:UIActivityTypeMail]) {
    NSString *theText = _someText;
    return theText;
}

if ([activityType isEqualToString:kYourCustomMailType]) {
    NSString *theText = @"Some text for your Custom Type";
    return theText;
    }

return @"Some default text";

将UIActivityItemProvider子类化主要是当您希望“提供异步的共享项”时。如果您只想自定义每个活动的有效负载，您应该创建一个符合UIActivityItemSource协议的对象。@1Pawan您好，您能确认这是否对您有效吗？您能确认这是否对您有效吗？
