如何从我的iPhone应用程序在Twitter应用程序中打开twitter页面？

The page I want to open using twitter app:

我想用twitter app打开的页面：

https://twitter.com/#!/PAGE

https://twitter.com/#!/PAGE

To open twitter app I use the following code:

要打开Twitter应用程序，我使用以下代码：

NSURL *urlApp = [NSURL URLWithString: [NSString stringWithFormat:@"%@", @"twitter://https://twitter.com/#!/PAGE"]];
[[UIApplication sharedApplication] openURL:urlApp];

But this code doesn't seem to work as expected, I got only twitter app launched without the page which i want to show.

但是这段代码似乎没有按预期工作，我只推出了没有我要显示的页面的推特应用程序。

You are looking for the following url:

您正在寻找以下网址：

twitter:///user?screen_name=PAGE

Note that Twitter is not installed on all devices. You should check the result of openURL method. If it fails, open the page in Safari with regular url.

请注意，并未在所有设备上安装Twitter。你应该检查openURL方法的结果。如果失败，请使用常规网址在Safari中打开该页面。

I know its quite a late response to this question and I agree that, Murat's answer is absolutely correct. Simply add a check as follows:

我知道对这个问题的反应非常晚，我同意，穆拉特的答案是绝对正确的。只需添加一个支票如下：

NSURL *urlApp = [NSURL URLWithString: [NSString stringWithFormat:@"%@", @"twitter:///user?screen_name=PAGE]];

if ([[UIApplication sharedApplication] canOpenURL:urlApp]){
        [[UIApplication sharedApplication] openURL:urlApp];
    }

I hope this helps someone. Cheers!! :)

The following code opens twitter page on twitter app if it is already installed, otherwise opens twitter on safari:

以下代码在twitter app上打开twitter页面（如果已安装），否则在safari上打开twitter：

NSURL *twitterURL = [NSURL URLWithString:@"twitter://user?screen_name=username"];
if ([[UIApplication sharedApplication] canOpenURL:twitterURL])
    [[UIApplication sharedApplication] openURL:twitterURL];
else
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.twitter.com/username"]];

Don't forget to replace 'username' with your name.

不要忘记用您的名字替换'username'。

        [appMissingAlertView release];

This is the full code required in Swift. I am using Swift 4 but i believe it is the same for Swift 3.

这是Swift所需的完整代码。我使用的是Swift 4，但我相信Swift 3也是如此。

let Username =  "YOUR_USERNAME_HERE" 
let appURL = NSURL(string: "twitter:///user?screen_name=\(Username)")!
let webURL = NSURL(string: "https://twitter.com/\(Username)")!
let application = UIApplication.shared
if application.canOpenURL(appURL as URL) {
      application.open(appURL as URL)
    } else {
        // if Instagram app is not installed, open URL inside Safari
        application.open(webURL as URL)
    }

Don't forget to add the Info keys needed to use canOpenURL:

不要忘记添加使用canOpenURL所需的Info键：
