LinkedIn和Google+ UIActivity View Controller按鈕？

Question

據我所知，UIActivity View Controller有一個Facebook & Twitter按鈕，但如果有服務通過UIActivityViewController共享到Google+或LinkedIn，我就會徘徊？

蘋果提供的類型中沒有一種可用，但您可以創建自己的。您可以創建一個UIActivity類，並把它傳遞到UIActivityViewController來處理髮送數據給每個你正在尋找的互動與服務：

DataItemProvider *dataToShare = [[DataItemProvider alloc] initWithPlaceholderItem:FileTypeToShare]; 

GooglePlusActivityType *googleActivity = [[GooglePlusActivityType alloc] init]; 
LinkdInActivityType *linkdinActivity = [[LinkdInActivityType alloc] init]; 

NSArray *activityTypes = @[googleActivity, linkdinActivity]; 
NSArray *activityItems = @[dataToShare]; 

UIActivityViewController *activityController = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:activityTypes]; 

[activityController setCompletionHandler:^(NSString *activityType, BOOL completed) { 
    //Put in your completion handle code here. 
}]; 

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

然後實現類都GooglePlusActivityType和LinkdInActivityType處理加載數據到兩個網站。
