标题: ios - UIActivityViewController 和注释

我的应用程序中有 UIActivityViewController 用于发布到 Facebook 等内容，但它也作为选项添加到 Notes 中，但由于 Notes 没有 UIActivityType，我无法排除它，但它也没有向 Notes 添加任何内容。我的代码是:

Mail *mail = [[Mail alloc]init];
    NSString *html = self.finalObject[@"Request"];
    NSString *thetitle = [self.finalObject[@"Title"] stringByReplacingOccurrencesOfString" " withString"%20"];
    NSString *thedate = self.finalObject[@"dateMade"];
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat"MMM_dd_yyyy"];
    [dateFormat setTimeZone:[NSTimeZone timeZoneWithAbbreviation"GMT"]];
    NSDate *theNewDate1 = [dateFormat dateFromString:thedate];
    NSString *theNewDate = [dateFormat stringFromDate:theNewDate1];

    mail.thehtml = html;
    self.nameofhtmlfile = [[[[@"http://www.iprayed4u.net/app/" stringByAppendingString:thetitle] stringByAppendingString"_"] stringByAppendingString:theNewDate] stringByAppendingString".html"];

    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems[self] applicationActivities[mail]];



        activityVC.excludedActivityTypes = @[ UIActivityTypePostToWeibo,

                                              UIActivityTypeCopyToPasteboard,

                                              UIActivityTypeAssignToContact,
                                              UIActivityTypeMail,
                                              UIActivityTypePrint,
                                              UIActivityTypeAirDrop
                                              ];



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

- (id)activityViewControllerUIActivityViewController *)activityViewController itemForActivityTypeNSString *)activityType {

    if ([activityType isEqualToString:UIActivityTypePostToTwitter]){
        NSString *test = [[@"I just pledged to pray.  You can pray too, just click " stringByAppendingString:self.nameofhtmlfile] stringByAppendingString" to view request.  Get #iPrayed4U here https://appsto.re/us/p_t30.i"];
        return test;
    }
    if ([activityType isEqualToString:UIActivityTypePostToFacebook]){
        NSString *test = [[[[[@"'" stringByAppendingString:self.finalObject[@"Title"]] stringByAppendingString"'.  "] stringByAppendingString:@"I just pledged to pray.  You can pray too, just click " ] stringByAppendingString:self.nameofhtmlfile] stringByAppendingString:@" to view request.  You can also get the app for free.  Check out iPrayed 4 U on iOS at https://appsto.re/us/p_t30.i #iPrayed4U"];
        return test;
    }
    if ([activityType isEqualToString:UIActivityTypeMessage]){
        NSString *test = [[[[[@"'" stringByAppendingString:self.finalObject[@"Title"]] stringByAppendingString:@"'.  "] stringByAppendingString:@"I just pledged to pray.  You can pray too, just click " ] stringByAppendingString:self.nameofhtmlfile] stringByAppendingString:@" to view request.  You can also get the app for free.  Check out iPrayed 4 U on iOS at https://appsto.re/us/p_t30.i #iPrayed4U"];
        return test;
    }
    return nil;
}
- (id)activityViewControllerPlaceholderItemUIActivityViewController *)activityViewController {
    return @"Some string";
}

我怎样才能让它从 UIActivityViewController 中删除 Notes，或者让它实际工作？

Best Answer-推荐答案

您不能排除 Notes，因为它不是系统事件:它是共享扩展。只有用户可以决定是包含它还是排除它。

现在您已经添加了其余代码，您可以看到 Notes 不保存任何内容的原因:您没有向它传递任何数据。当 Notes 请求数据时，您将返回 nil:

- (id)activityViewControllerUIActivityViewController *)activityViewController itemForActivityTypeNSString *)activityType {
    if ([activityType isEqualToString:UIActivityTypePostToTwitter]){
    }
    if ([activityType isEqualToString:UIActivityTypePostToFacebook]){
    }
    if ([activityType isEqualToString:UIActivityTypeMessage]){
    }
    return nil; // this is what you are sending to Notes
}
