如何在iOS应用中添加“在Facebook上关注我们”按钮？ [英] How can I add 'Follow us on facebook' button to an iOS app?

问题描述

我已经完成了我的iOS应用程序但只需要添加两个按钮：

I've about completed my iOS app but only need to add two buttons:

• 在facebook上关注我们


• 在Twitter上关注我们

我想我会在这里找到几个简单的例子，但很惊讶地发现根本没有答案（还）。

I assumed I would find a couple of simple examples here, but was surprised to find no answer to this at all (yet).

我很确定我可以在接下来的几个小时内试图解决这个问题，但我想我会伸手去拿有一点节省时间的帮助。

I'm pretty sure I could spend the next few hours trying to figure it out, but thought I'd reach out for a little time-saving help.

只需查看代码就可以查看视图控制器（XCode 4.5.1，iOS 6）上的按钮。

Just looking for the code to go behind a button on a view controller (XCode 4.5.1, iOS 6).

我假设我可能需要提供的唯一变量是公司的Facebook帐户名。

I assume the only variable I might need to supply is the company's facebook account name.

有什么建议吗？ （提前致谢！）

Any suggestions? (Thanks in advance!)

推荐答案

首先，Facebook的URL方案： fb：// profile /< yourpageid> （来源）。具有此结构的URL将打开Facebook应用程序（如果已安装）。

First, the URL schem for Facebook: fb://profile/<yourpageid> (source). A URL with this structure will open the Facebook app, if it is installed.

有关iOS URL方案的更多信息。

点击按钮时，您可以检查Facebook是否已安装：

When your button is tapped, you can check if the Facebook is installed:

-(IBAction)fbButtonTap:(id)sender {
    NSURL *fbURL = [[NSURL alloc] initWithString:@"fb://profile/<yourpageid>"];
    // check if app is installed
    if ( ! [[UIApplication sharedApplication] canOpenURL:fbURL] ) {
        // if we get here, we can't open the FB app.
        fbURL = ...; // direct URL on FB website to open in safari 
    }

    [[UIApplication sharedApplication] openURL:fbURL];
}

对于Twitter，您可以遵循相同的基本步骤。 iOS的Twitter URL方案是 twitter：// user？id = 12345 或 twitter：// user？screen_name = yourname （来源）。同样，如果没有安装Twitter应用程序，你可以在safari中打开twitter个人资料。

For twitter, you follow the same basic steps. The Twitter URL scheme for iOS is twitter://user?id=12345 or twitter://user?screen_name=yourname (source). Again, if the Twitter app is not installed, you have open the twitter profile in safari.

至于采取直接行动，我认为你不能这样做，因为关于设备上安装的任何其他应用程序，没有固有的知识。我认为你能做的最好的就是将用户引导到各自的账户。

As for taking direct actions, I do not think you can do that, since there is no inherent knowledge about any other applciation installed on the device. The best I think you can do is direct users to each respective account.
