UIActivity ViewController显示项目

Question

所以我已经把我的Activity控制器链接到一个共享按钮上了。每当我指向特定的项目时，它都会填充文本和图像，但是我使用的是文本和图像的数组，我希望它在用户滑动到下一页时自动填充数组中的项目。但它似乎没有正确地呈现自己。下面是我的代码：

{
    NSString *shareApp2 = @"Test Share Button";
    UIImage *shareImage2 = [UIImage imageNamed:@"challenge@2x.png"];
    NSString *shareChallenge = @"Challenge";
    NSArray *shareDays2 = self.pageDays2;
    NSArray *shareText2 = self.pageTitles2;
    NSArray *itemsToShare2 = @[shareApp2, shareImage2, shareChallenge, shareDays2, shareText2,];
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare2 applicationActivities:nil];
    activityVC.excludedActivityTypes = @[UIActivityTypeAirDrop, UIActivityTypePrint, UIActivityTypeSaveToCameraRoll, UIActivityTypeAssignToContact];
    [self presentViewController:activityVC animated:YES completion:nil];
}

问题出在这两行上：

NSArray *shareDays2 = self.pageDays2;
NSArray *shareText2 = self.pageTitles2;

如果我这样表示它，它将工作得很好，但它只会填充我指向的数组中作为Integer的特定项：

NSArray *shareDays2 = self.pageDays2 [0];
NSArray *shareText2 = self.pageTitles2 [0];

我已经尝试了多种ARC和Count或self presenting方法，但都没有成功，我知道我忽略了一些非常简单的东西。如果您需要源文件或更多详细信息，请让我知道，谢谢

尝试使用此代码进行共享：

NSString *textToShare = @"Look at this awesome website for aspiring iOS Developers!";

NSURL *myWebsite = [NSURL URLWithString:@"http://www.codingexplorer.com/"];

NSArray *objectsToShare = @[textToShare, myWebsite];

UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];

NSArray *excludeActivities = @[UIActivityTypeAirDrop,
                               UIActivityTypePrint,
                               UIActivityTypeAssignToContact,
                               UIActivityTypeSaveToCameraRoll,
                               UIActivityTypeAddToReadingList,
                               UIActivityTypePostToFlickr,
                               UIActivityTypePostToVimeo];

activityVC.excludedActivityTypes = excludeActivities;

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