LinkedIn和Google+ UIActivity View Controller按钮？

据我所知，UIActivity View Controller有一个Facebook & Twitter按钮，但如果有服务通过UIActivityViewController共享到Google+或LinkedIn，我就会徘徊？

苹果提供的类型中没有一种可用，但您可以创建自己的。您可以创建一个UIActivity类，并把它传递到UIActivityViewController来处理发送数据给每个你正在寻找的互动与服务：

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]; 

然后实现类都GooglePlusActivityType和LinkdInActivityType处理加载数据到两个网站。
