UIActivityViewController在共享時不顯示Facebook上的鏈接

Question

當我使用facebook上的共享功能時，我無法看到字符串和鏈接，下面是示例代碼。

NSArray * activityItems = @[[NSString stringWithFormat:@"Some initial text."], [NSURL URLWithString:@"http://www.google.com"]]; 
NSArray * applicationActivities = nil; 
NSArray * excludeActivities = @[UIActivityTypeAssignToContact, UIActivityTypeCopyToPasteboard, UIActivityTypePostToWeibo, UIActivityTypePrint, UIActivityTypeMessage]; 

UIActivityViewController * activityController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:applicationActivities]; 
activityController.excludedActivityTypes = excludeActivities; 

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

Answer 1

您的鏈接必須是NSURL對象：

NSString *link = @"http://itunes.apple.com/app/id00000000"; 
NSArray *activityItems = @[ [NSURL URLWithString: link] ]; 

Answer 2

您的鏈接在那裏，但它不作爲您的文章的文本的一部分內聯顯示。相反，它被看作是一個附件樣預覽：

如果你想看到的文字你的鏈接，將其添加到您的NSString活動項目：

NSArray * activityItems = @[[NSString stringWithFormat:@"Some initial text. An inline link http://www.yahoo.com"]]; 

這樣，您將看到字符串和鏈接：
