ios - UIActivityViewController：SMS選項不顯示

Question

我使用UIActivityViewController允許通過郵件，Facebook，Twitter和SMS進行共享。我有以下代碼：

-(void) aFunction 
{ 
NSString *textToShare = appRecord.title; 
UIImage *imageToShare = [UIImage imageNamed:@"test/png"]; 
NSURL *url = [NSURL URLWithString:@"http://www.stackoverflow.com"]; 
NSArray *activityItems = [[NSArray alloc] initWithObjects:textToShare, imageToShare,url,nil]; 


UIActivity *activity = [[UIActivity alloc] init]; 

NSArray *applicationActivities = [[NSArray alloc] initWithObjects:activity, nil]; 
UIActivityViewController *activityVC = 
[[UIActivityViewController alloc] initWithActivityItems:activityItems 
            applicationActivities:applicationActivities]; 

activityVC.excludedActivityTypes = @[UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypePrint ,UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypeSaveToCameraRoll,UIActivityTypeMessage ]; 

[self presentViewController:activityVC animated:YES completion:nil]; 
[activityItems release]; 
[activity release]; 
[applicationActivities release]; 
[activity release]; 
} 

的代碼產生如下：

短消息服務選項丟失。我做錯了什麼？

您排除UIActivityTypeMessage（excludedActivityTypes）。這隱藏了消息（SMS/iMessage）選項
